Massive power for a wide range of audio applications

Connect this 2 x 140-watt beast to the preamp outputs of a receiver or a wireless music player such as the Sonos Port. Add a pair of speakers that can handle the high power, and get ready for a breathtaking sonic thrill ride.

Use the MM7025 in your main listening room to drive your primary speakers. Expect to hear tighter, weightier bass, and wider dynamic swings that bring you closer to the sound of live music. (If your speakers can be biamped, this Marantz makes a superb choice for driving the low-frequency half of your system.)

Audiophiles using a preamp or A/V processor with XLR outputs can connect to this amp's XLR inputs and take advantage of the superior sound quality they provide. You could also use this amp to power a second zone. If you're using a speaker selector to divide the second-zone power among multiple rooms, don't worry. There's plenty of juice here to go around.

The MM7025's current-feedback amplifier design provides for nuanced reproduction of fine musical detail and plenty of sonic muscle to support chest-thumping transient peaks. HDAM-SA3 circuits provide high-speed signal response for precise sound.

Product Research

Features

Current Feedback: The MM7025 is equipped with a current feedback circuit and uses the same complimentary push-pull circuit as the far more expensive SM-11S1 power amp, providing minimal phase shift and excellent detail resolution. The current/voltage conversion section has a Wilson current mirror circuit to improve circuit stability and high-speed processing.

Instant Power Supply: The final stage of the power amp uses the same LAPT (high efficiency power transistor) as the SM-11S1, offering instant power supply capability. The power section has a large transformer and Marantz original 15,000 μF / 71 V x 2 block condensers to provide a powerful, presence filled sound.

Heat Dissipation: The chimney-shaped heat sink efficiently processes the heat emitted from each side of the amp and a quiet cooling fan removes the heat from the chassis. A high-sensitivity temperature sensor IC is used to control the cooling fan's rotation speed to match the amount of heat generated by the amp.

Auto Standby: With the Auto Standby Mode is turned on this unit will enter standby mode after approximately 30 minutes (continuous) with no input signal.

Speaker Outputs: The speaker output terminals are binding posts; they are not 5-way posts, but will accept single banana plugs, pin connectors, and bare wire. A plastic collar prevents their use with spade lugs and they're too far apart for dual banana plugs.

Inputs: There are RCA (unbalanced) and XLR (balanced) inputs. Separate switches for the left and right channels specify which is engaged; useful if you're not using the MM7025 as a stereo amp.

Display: A blue indicator on the front panel display and a blue ring around the display light when the power is on; the blue ring around the display can be turned off if you prefer. Separate red indicators on the display light when the protection circuit or Auto Standby feature is engaged.

Remote Power Control: This unit is equipped with a remote power control function; when a compatible Marantz preamp is connected, this unit's power can be switched on and off simultaneously with the preamp. The RCA Remote Control input is connected to the preamp and the Remote Control output can be connected to other compatible Marantz components; CD player, DVD player, Tuner, etc.

Flasher Input: The IR flasher input is useful with universal remote controls; power and mute remote codes are available for the MM7025.

DC Control: The 3.5mm mini-jack input allows the MM7025's power to be controlled by another device (5-15 V). The DC Control output allows the MM7025 to control the power of another compatible device (12 V/44 mA).

Can I use a maranta PM 6007 as a preamp on this unit?
mike  Sep 06, 2023
2 answers
A
Thank you Hogan.
mike  Sep 07, 2023
A
Greetings Mike, and thanks for your question. The PM 6007 has just a fixed record out, that output being fixed would not attenuate the volume, with the control on the PM 6007. Now on the amp. Its just a power amp, it has no control for volume. Technically, you can connect the two, you just would have no way to control the volume or tone on the record out. What you need to use as a preamp for the MM7025 is something with a variable preout.

A
This power amp cannot be used without a preamp processor or a receiver with preamp outputs. We do have preamp processors and receivers that will work with this power amp and let you connect all three of those devices. I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation on which one to use with this power amp.

Q
Does the marantz mm7025 wil drive fine My Wharfedale lintons that are listed at 6 ohms and fall to 3.5 ohms???? Or better Buy the nad c 268 that are confortable with any impendance???
carlos espinoza  Jun 25, 2023

Q
Hi, I'm looking to add Marantz MM 7025 to my NAD 3025 V2 and power up my Wharfedale 80th Denton. Is the MM7025 too much power for my current speaker set up?
singe  Jan 18, 2023
1 answer
A
The MM7025 is capable of 170w per channel output when presented with a 6-ohm impedance. This would exceed the recommended power rating of 20-100w per each Wharfedale Denton 80.

Q
Is amplifier will be good with dynaudio evoke 20?
alexander  Jan 02, 2023
1 answer
A
Unfortunately no. The Dynaudio Evoke 30 are 4 ohm speakers and the Marantz MM7025 is only stable down to 6 ohms meaning the Evoke 30s would overheat the amp. If you'd like a recommendation for those speakers give us a call at 1-800-324-9695 and we'd be happy to make a better, more personalized recommendation!

Q
I was hoping to buy this amp to power my klipsch rp-5000's. Will running 140 watts do any damage as spec sheet from klipsch calls for 125 rms? Also, i know i would use you my current receivers preout where would that (RCA) input get connected in the mm7025? looking at the back i dk t think there i didnt see a rca input.
mike  Sep 18, 2022
1 answer
A
So there are RCA inputs on that power amp, there are located directly above the XLR inputs. The left and right are separate from each other which can make a little less than obvious. In regards to powering your speakers, you could still use this power amp to run your Klipsch towers however you would need to be mindful of how hard you run those speakers. Out of an abundance of caution, it's understandable to get closer to suggested RMS range though.

Q
I have a Marantz SR7011 with Bowers and Wilkins 703 S2 towers, HTM 71 S2 Center, two SVS PB 2000 Subs, and Polk FXi A6 sides and rears (waiting to afford swapping for B&W sides and rears). Current setup sounds great at higher volume. Wondering if adding this power amp would make much of a difference for home theater and music?
rich  May 24, 2022
1 answer
A
Hello Rich! Thank you for reaching out to us and that is a fantastic question. Using a power amp, especially one like that Marantz MM7025 would make a big difference with your system. You will get more power and better performance out of the speakers connected as opposed to running them directly off of the SR7011 so whether you are using the full theater set up or just music, you will appreciate the difference even at low to moderate volumes.

The Klipsch efficiency should make this a great amp to drive them. I drive KEF R7's which have an efficiency much lower than the Klipsch and I do have to crank it a bit (60%) to make them really come alive, the MM7025 is rated to 140 w rms into 8 ohms, so you should be good to go.

It is a 2 chanel amp. It would power either the floor speakers or the center very well. I use it to bi-amp old Paradigm floor speakers. I love the amp. It brought life back to my speakers. Nice clean power for the price.

I don't own the PM7000N. I own the PM8006. There are pre-outs on the PM8006 that I do not see on the PM7000N. I would suggest checking with Aaron at Crutchfield to confirm. He is good and if he does not know he will find out quickly.

But then again it looks as if 6006 has volume control. So you would not need a preamp after all.
casey  Jun 09, 2020
A
Well now that I look a little deeper, you would need a preamp to go between. The MM 7025 had no volume control it's just an amp. So again you would need a preamp. Hope that helps.

Where or how do I hook up my powered sub ?
sean  Mar 03, 2020

A
You can't. There is no output for a subwoofer.
casey  Apr 02, 2020
A
This amplifier does not have a subwoofer connection. It is 2 channels with 140 watts of power per channel. It delivers beautiful, balanced sound and effortlessly drives my Martin Logan 60s main speakers. I use a Denon 3500 receiver to drive my center, rear channel, and subwoofer speakers. I would highly recommend the Marantz if you have another power source to drive your subwoofer.
joseph  Apr 01, 2020
A
You can not do that. This is just a amplifier only.
eric  Apr 01, 2020
A
This amp is not designed for a sub pre out. You need an a/v receiver w/pre outs or a stand alone pre amp.
richard  Apr 01, 2020
A
Some subs accept a connection directly from the speaker outputs. If that is not the case, you may need a 3rd device. In my case that device is an ADI-2 DAC and I use the RCA outputs from the DAC to feed my sub. But it does not have to be an expensive DAC. Anything that accepts the low level signal and splits into two would work if it has the correct connectors. For example, if your sub accepts RCA inputs it could be an RCA audio splitter. Then, you can feed one pair of the splitter's output to your amp's inputs another to your subs inputs.

richard  Feb 14, 2020

Hi Mark, thank you for your question. Since the Marantz MM7025 does not have volume control, you would need a preamp to gain the ability to connect other devices to this amp, including an AM/FM tuner. Feel free to chat with us on line or by phone at 1-800-324-9695. We will be happy to go over this setup with you, and offer personalized recommendations based on your needs.
jessica  Feb 07, 2020 (Staff)

A pre-amp is needed to connect to this amp prior to connecting any devices.(unless they have a gain setting of some sort which is usually only on high-end CD players)
dave  Feb 07, 2020
A
no, there would be no volume control.
casey  Feb 07, 2020
A
I believe a tuner would need to run through a preamp. If you have a receiver with pre outs, you can use the pre outs with this amp. A receiver includes a tuner. That's what I am doing. Hope that helps.

Q
Is there significant improvement in sound quality if the MM7025 amp is connected to the Marantz SR7011 for music w/Klipsch Chorus II speakers listening at low-mid volume levels?
jerome  Sep 14, 2019
4 answers
A
I DO NOT USE THOSE COMPONENTS WITH THE AMPLIFIER.
kenneth  Oct 10, 2019
A
There will not be any significant improvement in sound quality but the MM2075 will pair nicely with your SR7011 and take a significant amount of the power demands away from your receiver which should help with potential clipping and overheating issues. The MM2075 delivers powerful yet nuanced sound quality and will definitely be an excellent complement to your SR7011.
joseph  Oct 09, 2019
A
Mine is connected to a Marantz SR 7010 and the sound Is outstanding
robert  Oct 09, 2019
A
Great question. I have not heard the Chorus speakers so I can not attest to sound or quality of sound coming out of them via the 7011. They are really efficient speakers, 101db, so you don't need a lot of power However, I have found myself and have been told by others with much more first hand knowledge about this sort of thing that anytime, any speaker has a dedicated power source, like the 7025 (or really any dedicated amp) it will produce a better sound quality than trying to boost it with an internal amp from an AVR and then adding an amp. Less "noise" in the signal + more direct path = better sound. Hope that helps

audiobully  Aug 02, 2017

I think not. You would have to have some sort of output to connect to a preamp before linking to the power amp. I f there is an output option on the NA I would assume you could link to the power amp via an auxlliary input.

Q
Can you use this amp as mono to each front tower speaker?
numan  Oct 12, 2016
4 answers
A
Yes you it can send mono to each front tower speaker as long as the input device hooked up to the amp is sending mono to both speakers. Basically it is a pass-thru from input device to speaker so whatever signal is sent to the right speaker is what is amplified to the right speaker. Whatever signal is sent to the left speaker is what is amplified to the left speaker. The only change to the signals sent is that they are amplified, (made louder), so that the input device doesn't have to have its own amplifiers for each channel. Hope that this answers the question to your satisfaction, and helps. ;o)
charles  Oct 13, 2016
A
I'm not quite sure what you mean. If you want to only connect one speaker to the amp, vice two, then yes is the answer. An amp is a pretty dump device. It merely amplifies the sound, and maybe cleans up the sinewave of the output from your receiver or preamp device. I have a preamp and eight speakers (no center channel). I use the 7025 for my front left and right. Then another 7 channel amp for the other six surround speakers.
todd  Oct 13, 2016
A
Yes
nancy  Oct 13, 2016
A
Yes you can. I would check your speaker power maxium as you dont want to overpower them and risk damage. Your tuner/reciever will need to have enough pre out terminals to send signal to two amps.

I have components (DVD player, satellite radio and am old cassette tape player) hooked into an NAD pre-amp/tuner powered by the Marantz. Does your receiver have an integral amplifier? if so that may be a problem. If the receiver puts out an un-amplified signal I would think it would
patricia  Aug 05, 2016
A
This is a question for the experts at Crutchfield. As per the "about tech" Website, "...the R-S700 (includes a) multizone/multi-source feature, which allows a listener in Zone 2 to hear a different source than the main room. The receiver's non-powered Zone 2 output requires an amp and two speakers in the second zone. It comes with a separate Zone 2 remote control to operate the receiver from another room. Note: Multizone operation requires running speaker wires and IR (infrared remote) control wires from Zone 1 to Zone 2, which may require professional installation." The Marantz MM7025 will provide very good to excellent power amplification for zone two. Although it has a remote control connection via an RCA plug cable, the Yamaha uses IR. Given this, the remote operation may not work. Bill M.
william r  Aug 04, 2016
A
That all depends. Please follow the link above, and see if this will help answer your question. The MM7025 is a two channel amp. The Yamaha R-S700 appears to be a 2 or 4 channel receiver, depending on whether your speakers are 4, 6 or 8 ohms rated. I'm not quite sure that you will gain much with the addition of the MM7025, if all you are using only 2 channels. Best to check the web site at audioholics(dot)com for best practices.
todd  Aug 03, 2016

If your amp has main out and in yes.other factors are speakers. Over all very satisfied with my purchase very solid amp. Clear with good punch. Component compatibility will always be a factor. Your system for me can only be as good as your speakers

hello I have a sony str-dn1050 and was told this is nice amp ,I would like to buy but want to make sure it will work,i have only two polk speakers as of now and have it bi-amped , had 1 guy say I would need a receiver with pre-amp outputs and had another guy say it will work on zone 2? so im looking for a third opinion? and lets say it does work will I still b able to use all the features of the receiver? thanks for doing the homework on this,i don't want to have to return it..oh and my sony runs on 6 olms if this makes any diff? but ty mark
mark  May 04, 2015
2 answers
A
To bi-amp with that Sony model, you will want to use the Sony to power the high frequency section of your Polks and then connect the Marantz to the zone 2 / "B" speaker outputs of the receiver, to drive the woofers. You will have to go into the set-up menu and select "A+B" speakers. Sony rates the receiver into 6 Ohm loads. All that means is you should be confident that it will drive speakers that are rated at 6 Ohms (or higher) safely. Only analog signals will be output from the "zone 2 / B speaker" output. That should not be an issue.

Hi Mark, Sorry but I can't help. I actually returned the receiver and never opened it. I was in the middle of painting and remodeling and figured it wasn't a good time to be messing around with this. Thanks, Pat

Q
I see that the instructions say this amp goes into standby after 30 minutes of not sensing input signal, but will it turn on automatically when it senses signal again? basically, does this amp have an signal sensing auto on feature?

The short answer is yes, it will turn on automatically. I use an RCA cable from my Marantz NR1510 receiver's remote control "output", and connected to the remote "input" on the MM7025. I use the pre-amp output from the NR1510, connected to the MM7025, which drive my older Klipsch RF-82's very well. Pretty sweet in fact!

Yes, but you don't have to use it. It's purely optional. It also has a 12V trigger, which works great for me.

So frustrating it has no auto on feature... I have 5 airplay zones in my home and need and amps I can leave installed in a cabinet that turn on and off automatically when signal is sensed from an Airport Express. I have some older Sonance amps that do that now, but 2 have failed and I need to start replacing them with something better.

My system shuts down after 30 minutes (phone call with mother-in-law) and did not restart automatically.

I have the mm7025 hooked up to a Marantz receiver there is a remote control cable as well as signal cables to the amp from the receiver. When I turn the receiver on the amp comes on .5 sec delay. the amp stays on as long as the receiver is on. It does go into standby mode when there is no audio signal present, but when in standby the ON blue light stays lit and the fan shuts down. The Amp is truly amazing as far as construction, twice the amp for the money compared to other brands..

I have seen no evidence that it has an auto on feature. My answer would be no to your specific question. However, it does have the capability to install a "trigger", which detects that another device has been turned on. For instance, I have a series of amps, only have to turn on one, the rest are automatically triggered.

I am going to us this with a older model sony reciver M#strde885 with a subwoffer and a pair of klips towers I all ready get a 100 watts per channel but am looking to get clean and clear sound ,my question is will the amp make much of a difference? Dan C

It depends on how hard you push the Klipsch now and how stout a 100W the Sony receiver is. Most A/V receivers, especially towards the lower end of the market, can't deliver anything like their rated power to all channels simultaneously. The Klipsch should be a relatively easy load, though, so unless you're really rockin', your Sony receiver should have enough power to drive them easily -for stereo music that is. If you like to crank up action flicks, putting an amp like the Marantz on the front channels will really lighten the load on your receiver. And even for stereo music listening, if you like the bass and like to listen at life-like levels, the bigger, beefier amp will definitely do a better job.

Does this amplifier have a cooling fan? If so, how loud is the fan? I may be sitting within 6 feet of the amplifier. I don't want to hear the fan during the quiet intervals.

Have never heard the fan. It does have one.

It does have a cooling fan. It's speed is matched to the amount of heat that is being generated. I have had this amp for over a year, use it almost daily and have never heard the fan run. This amp has a very low operating temperature.
