Our take on the Russound X225

Today's networked audio players, music streaming services, and remote control apps for smartphones and tablets have radically changed the way we experience music at home. You still need good clean power to drive your speakers, but you probably don't need a traditional receiver with a lot of buttons to push. Maybe all you really need is a smartly automated amp like the Russound X225.

Today's networked audio players, music streaming services, and remote control apps for smartphones and tablets have radically changed the way we experience music at home. You still need good clean power to drive your speakers, but you probably don't need a traditional receiver with a lot of buttons to push. Maybe all you really need is a smartly automated amp like the Russound X225.

Connect one music component as your primary source, and it will activate the amplifier when it sends out an audio signal. The amplifier returns to standby mode when the audio signal ceases. Your secondary audio source takes over automatically when there's no signal coming from the primary source. There's no need to manually switch inputs.

Say you have a network audio player, such as a Sonos ZonePlayer 90 connected to the primary input. Any time you fire up the ZonePlayer, your X225 turns itself on and feeds the music to your speakers. Because the X225 has two sets of speaker outputs, you could be listening in the den, the kitchen or wherever you chose to install your speakers. Because you control the ZonePlayer with a wireless controller or smartphone app, it doesn't matter where you put it. The ZonePlayer and the X225 could be out of sight in a utility closet or cabinet.

You might connect an old-school music source like a CD player to the secondary input, and enjoy it whenever you're not using your ZonePlayer. When a CD stops playing, the X225 will automatically switch to standby mode.

Russound x225 Home Stereo Amplifier

Steve from Stockton, California on 1/28/2014

Crutchfield Customer Review (What's this?)

Simply put, this Home Stereo Amplifier is a Audiophile's dream. I needed to drive a pair of Cerwin Vega 'AT-15' Home Stereo speakers(on R & L 'B' speakers) that I rebuilt from the inner cabinet to the speakers (woofer & tweeter in each cabinet on only.) Woofer replacement- I went with 2 ROCKFORD FOSGATE 8 ohm(rated at 300 W. each), and two 4 ohm car 'metal bullet (horn)' tweeters . And I also have another pair of KLIPSCH Chorus II speakers that I worked over a while back(on R & L 'A' speakers), and both pairs of large Home Stereo speakers sound very nice on the Russound x225 amplifier. And being my YAMAHA Home Stereo equalizer has a 'output level', I turned the 'primary volume' on the Russound all the way up, and I turned the 'output level' on the equalizer to about 2 (goes to 10). The YAMAHA receiver has 80 W. (8 ohm) per channel, and the Russound has 150 per channel (8 ohm). Yes it is a great Amplifier(and well worth the money!) that I got on sale at Crutchfield.

Pros: it is very powerful!

Cons: I did not realize how important the small Right & Left (small) 'PRIMARY VOLUME' controls on the reverse are as the 'owner's manual' does not cover the importance enough - turning these up: you can be in for a big, and unpleasant surprise. Do so VERY SLOWLY, and CAREFULLY.

Excellent Amplifier

Joe from PR on 12/29/2013

I have used this amplifier during last two years to hear stereo music. No flaws. Excellent sound. To be honest, the best sound I have ever heard from a Hi-Fi system. Just connect the source directly to it (no pre-amp) and you will hear a no coloring sound very close to the original recordings. Volume is controlled using master volume level buttons behind the unit, and fine tune volume trim knob in front. The purchase of this amplifier is the most important music decision we have ever done to put a lot of satisfaction to this hobby. Of course you have to keep care of others important aspects such as good sources, speakers, cable interconnects, low resonance music rack, etc., etc. We also own the model Russound X125 placed in a smaller room (20' x 14'). Similar results.



Nice Amp!!

Cannot Recommend

WayneF from The Woodlands, TX on 10/23/2013

Crutchfield Customer Review (What's this?)

Bought one of these, set it up and it sounded good. Not great, but for the price and less than optimal specs, it was okay. After a while we noticed ends of songs were being "cut off" and the beginnings of songs did not start until a half-beat or so into the song. Once we noticed it, it became very apparent and somewhat annoying. We tried adjusted all settings and nothing seemed to help. We called tech support and it was suggested that we use a stereo mini jack to connect the pre-amp to the power amp via the 12v trigger. It didn't help. Called back and explained the issue to customer service and tech support. We called so many time we don't remember who told us that wasn't normal, that the Russound should switch off after receiving no signal for 2-4 minutes but not between songs on a CD or any source, and certainly not before a song is over, at any volume. Dealing with audio components for over 40 years, we have never experienced this. The tech support person suggested he send us a return authorization as well as a new unit that day. The second unit did the same thing. We tried different sources - CD, turntable, MP3 - all with the same results. We then connected everything back to the integrated amp we were using as a pre-amp and everything worked fine, so we are confident the problems lie with the Russound amps. We would not recommend this product.

Pros: Low price

Cons: Shoddy performance Poorly written owners manual


Hands-on research

Product Research


Overview: The Russound X225 is a dual source 2-channel power amplifier. The X225 features volume and balance controls, as well as A/B speaker switching on the front panel.

Power Output: The X225 is a Class D amplifier rated at 225 watts per channel into 4 ohms, and 150 watts per channel into 8 ohms. Both amplifier channels can be bridged for a higher power mono output of 470 watts into a single 8 ohm load (The Stereo/Bridge switch on the back panel should be in the Bridge Mono position when bridging.)

Signal Sensing Inputs: The X225 can be turned on manually or automatically by setting a switch on the rear panel. For manual power, the front panel power switch turns the unit on or off. When set to automatic, the unit will power on when music is sensed on either RCA input connector. Once the signal is no longer detected, the unit will automatically shut off. The signal sensing feature also allows you to switch from one input source to another by turning one of the connected components on or off. Signal sensing inputs allow the amplifier to easily integrate with multi-room audio systems and home theater components.

Line Level Output: In addition to the line level inputs, the X225 has a stereo RCA line level output. This output allows you to send the audio of the selected source to another amplifier.

Speaker Level Signal Inputs: If you have a source that is only available as a speaker level signal, you can connect it to the amplifier via the spring clip input terminals on the back panel. Only one set of speaker level inputs can be utilized and assigned by the selector switch. You can set the speaker level input as the primary or secondary signal.

12V Trigger: On the back panel, there two 3.5mm minijacks for a 12-volt trigger input and a 12-volt (100mA) trigger output. These allow the amplifier to be activated by, or to activate, other devices with a mini-plug cable. The trigger delay can be set between 3 and 15 seconds.

Thermal Protection: The amplifier is designed with a special circuitry that protects the unit under a thermal overload condition. Thermal protection mode will only engage when the unit has been run at high volume for extended periods without adequate ventilation and/or when speaker impedances are below the minimum levels. For proper ventilation, it is recommended that the amp have a minimum of 2" of clearance around each side of the unit.

Short Circuit Protection: In addition to thermal protection, the X225 also has special circuitry to protect the amplifier from short-circuit conditions. This can be caused by a faulty speaker or when speaker wires come in contact with each other. When this condition occurs, the amplifier will shut down until the short circuit is corrected.
