Alpine MRA-F350

Overview

Our take on the Alpine MRA-F350

Now Alpine makes it easier to experience multi-channel DVD sound in your vehicle. The MRA-F350 Digital Theater 5-channel amplifier, controlled by a compatible Alpine in-dash stereo, delivers full multi-channel sound with stunning realism.

This amplifier requires a compatible Alpine head unit and an optical cable.

Now Alpine makes it easier to experience multi-channel DVD sound in your vehicle. The MRA-F350 Digital Theater 5-channel amplifier, controlled by a compatible Alpine in-dash stereo, delivers full multi-channel sound with stunning realism.

The amp's all-digital design delivers 50 watts to each of five channels, supplying the front, rear, and center-channel speakers in your system with plenty of clean power. A subwoofer preamp output routes the low frequencies to your subwoofer amplifier.

Hook up a digital source like a DVD player or a game system to the optical digital input, and the amp's internal processors convert the digital info into surround sound. Another bonus — built-in Dolby Pro-Logic II processing brings convincing multi-channel sound to your standard stereo CDs.

All the amplifier's functions are controlled right from the touchscreen of your compatible Alpine receiver — the amplifier has no built-in controls. Alpine's sophisticated Bass Engine processor allows you to adjust the output to best complement your system.

Overall good amp, got it when I bought my head unit. only two gripes, slightly underpowered for speakers with a low sensitivity rating, also it disables the rca out's on the back of the head unit (volume control wise) so you can't use any more amps for mids.

    Crutchfield Customer Review (What's this?)

    I got this amp for my alpine iva w203, and the monster optical cable that is reccomened for, and the local installers said it does not fit, but i called customer service and they said it deffinitly fits, so far i am very dissapointed, i would not buy this again!! a waste of time, just get a nice four channel amp and you will be satisfied...

    Crutchfield Customer Review (What's this?)

    I added this to my ALPINE IVA-D100.First I would like to say when I first got this amp I was not very happy but when I started to read the directions to find out how the set up everything it made me realize I got a great amp for a steal. The first problem I had was the volume it sounded like it had no power at all but after going through all the option on my touch screen and changing things it starting sounding great and I can tell you this till this day I am learning great new things with this amp. The one big thing I can tell you is read on the different things this amp can do and how they work because thats when you are going to see the difference what this amp can do than any other amp. Remember dont give up on it.

    amplifier and digital sound processor in one,great deal

    Crutchfield Customer Review (What's this?)

    I bought this with an IVA-W205 head unit. What a great idea having the digital processor built into the amp! Instead of several pairs of RCA cables from the headunit to the amp all I had to run was the AI-NET and optical cables. No remote-on needed either,although I did have to run one from the headunit to the subwoofer amplifier. If you're not running a center channel,make sure you set it to OFF when doing the speaker settings. I was watching Transformers on DVD and almost all the voices were missing,I noticed the center channel setting was ON and upon changing it the voices were back. Alpine doesn't list it in their specs,but I think the subwoofer preamp output voltage is probably 2 volts because I had to set the subwoofer amplifier's (Blaupunk PA series I bought from Crutchfield many years ago) gain quite high. I would've given this amp a 5 rating if it weren't for this. They also should have added a remote-on connection at the amp itself to trigger the subwoofer amp(s). This is a great price for this amplifier,plus additional $ off if you buy an Alpine DVD receiever is a steal! If you're purchasing one of the recievers listed you definitely should spend the extra $ and get this amplifer if you want true Dolby Digital/DTS/ProLogic II. Without this amp or an Alpine processor you'll only have a 2-channel downmixed version coming from the headunit's RCA outputs.

    Crutchfield Customer Review (What's this?)

    This amp is fantastic, stellar surround sound and loud clear output thanks to the digital signal path. Hook it up to a 1-DIN Alpine center channel speaker and you will be amazed. It makes a slight clicking sound when switching functions in the menu on my head unit. The noise isn't loud enough to damage the speakers and is simply a minor annoyance. This is a very small issue and you can easily get around hearing any "pops" from the speakers by simply lowering the volume and then turning it up after you select the Chapter you wish to view, or DVD-Audio track you wish to hear etc. I never hear any clicks or pops when navigating my I-pod or playing CD's etc. I love this amp it is the corner stone of my system and a great match with a double DIN Alpine receiver and well powered sub. I matched this with a mono block Alpine amp that pushes 500 watts at 4ohms to a single 10" Sub (JL Audio Stealth box). This amp is an amazing deal and its performance will leave you grinning from ear to ear.

    Clean, powerful sound

    Written by: Christopher from North Port, FL on March 8, 2008

    Crutchfield Customer Review (What's this?)

    This is a fantastic amp and a good deal. The installation of this amp may be a bit overwhelming for a DIY, inexperienced installer. As the other review for this product pointed out, finding an optical cable both long enough to run from the deck to them amp that also has small enough connecters to fit the awkward Toslink connector on the head unit may prove challenging. Also keep in mind that fiber optic cable is more easily damaged than traditional copper cables, and special care needs to be taken routing it. Optic cable is pretty expensive, so keep these things in mind. As Crutchfield warns, this unit requires special Alpine decks (not just any Ai-Net deck will do). Also keep in mind that the optical cable input is REQUIRED, and that Ai-Net will NOT send an audio signal to the amp (even though it does for most other Alpine products). If you can get over these difficulties, you will be presently surprised. The fiber optic cable creates a crystal-clear input even at max volume levels. The clean, powerful output makes the speakers really shine, though the choosiest audio enthusiasts may want a bit more power. The real highlight of this product, though, isn't really the amplifier; it's the sound processor. Obtaining highly detailed, fine-tuned control of the soundscape via your Alpine head unit can create a new appreciation for your music and movies. Any serious car audio enthusiast should consider this product, even for 4-channel setups like my own (since the center channel can be turned off).

    Spectacular Deal

    Crutchfield Customer Review (What's this?)

    I bought this amplifier as part of the AV head unit deal Crutchfield is running, and have it paired up with my Alpine IVA-W205. I have to start by saying that it was an amazing deal.<BR><BR>When you buy this amp and pair it up with a compatible alpine deck, you're really buying 2 pieces of equipment at the same time. You get the digital amplifier, which is capable of decoding dolby surround, and on top of that you get a pretty sick audio processor / eq as well.<BR><BR>The built in audio processor / eq gave me a ton more control over my sound than what was built into my deck: tunable crossovers, time correction, multi-band EQ for front and rear, and the list goes on. <BR><BR>A couple words of warning however. Be wary of the optical cable you buy - if you're going to spend a ton of money on a nice cable, make sure it has connectors with a slim profile. I bought a Monster brand cable and the connectors at the ends of it were so thick that they wouldn't plug into my deck or the amplifier. The deck (IVA-W205) has the optical port oriented so the cable lays flat against the back of the deck, and the amplifier's optical port is recessed a hair more than it should be.<BR><BR>Also, at 50 watts RMS per channel this amplifier is slightly underpowered for higher end speakers. This said, I have it powering a set of components and a set of 6x9s and they still sound great.<BR><BR>All of that said, I dont think you can beat this amp for the money.

    Features

    Overview: The MRA-F350 is a five channel Car Theater (as opposed to Home Theater) amplifier designed to power your front (left and right), center, and rear (left and right) speakers, while a preamp output feeds your subwoofer amp. This amp requires a compatible Alpine head unit for set up and control. By itself, the amp offers no stand alone capability. Surround sound processors are built-in and also controlled by the head unit. The following head units include controls for this amp: IVA-D100, IVA-D105, IVA-D106, IVA-D310, IVA-D901, IVA-W200, IVA-W205, IVA-W505, DVA-9860, DVA-9861, and DVA-9965.

    Surround Processors: This amp has three surround sound processors built-in:

    • Dolby Digital: Plays Dolby Digital soundtracks in as many as six discrete channels (5.1)
    • DTS: Plays DTS soundtracks in as many as six discrete channels (5.1)
    • Dolby Pro Logic II: Simulates 5.1 channel playback from a stereo source (CD, FM Radio, etc)

    Crossovers: The MRA-F350 has four separate crossovers. All but the low-pass (subwoofer output) can be turned off for full range operation:

    • Front left and right (channels 1&2): variable high-pass from 20-200 Hz in 1/3 octave steps, selectable slope of 6, 12, 18, or 24 dB/octave
    • Rear left and right (channels 3&4): variable high-pass from 20-200 Hz in 1/3 octave steps, selectable slope of 6, 12, 18, or 24 dB/octave
    • Center (channel 5): variable high-pass from 20-400 Hz in 1/3 octave steps, selectable slope of 6, 12, 18, or 24 dB/octave
    • Subwoofer (pre-amp out): Variable low-pass from 20-200 Hz in 1/12 octave steps, selectable slope of 6, 12, 18, or 24 dB/octave

    Subsonic Filter: In addition to the low-pass crossover, the subwoofer output also has a subsonic filter. The frequency is variable from 20-50 Hz in 1/6 octave steps with a selectable slope of 6, 12, 18, or 24 dB/octave.

    Subwoofer Output: The subwoofer output is a line level signal (RCA) with a low-pass crossover and subsonic filter. The phase of the sub output can be reversed; 0° or 180°.

    Time Alignment: The built-in surround processors offer time alignment for all six channels (5.1) to compensate for the less than perfect speaker positioning typical in a car. The delay range runs from 0-20 milliseconds in 0.1 ms increments.

    Equalizer: The MRA-F350 has a parametric equalizer with a total of 17 bands; five for the front, five for the rear, five for the center, and two for the sub. The center frequencies are adjustable from 20-20 kHz in 1/6 octave steps. The width of the EQ band (Q) can be adjusted to 0.5, 1, 2, 3, 4, or 5. The adjustment level is +/-9 dB.

    Optical Input: The amp has an optical digital (standard Toslink) input for use with digital sources, such as a DVD player, game system, etc.

    STAR Topology: Alpine's unique STAR (Signal Transit for Accurate Response) Circuit PCB design provides a single common ground for all amp sub-blocks, preventing ground interference and minimizing internal noise.

    Compatibility

    Head Unit: The MRA-F350 requires a compatible head unit for setup and control, it cannot be used without one. The current list of compatible head units includes (but is not limited to): IVA-D100, IVA-D105, IVA-D106, IVA-D310, IVA-D901, IVA-W200, IVA-W205, IVA-W505, DVA-9860, DVA-9861, and DVA-9965.

    Speakers: Although the original manual lists bridging instructions, per Alpine: The amp is not bridgeable, and it's designed to power 4 ohm speakers.
