About 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.

    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.

    Inputs and Outputs

    Left Side of Amplifier:

    • Speaker Outputs: terminal strip outputs for all five speakers; each terminal is 0.338" wide
    • Power and Ground: screw terminals for power and ground that will accept up to 8 gauge bare wire (8 gauge recommended); each terminal is 0.338" wide

    Right Side of Amplifier:

    • Guide Control: 2-pin jack for connecting an outboard controller
    • Digital Input: Toslink optical digital input for digital sources (DVD, Game system, etc)
    • Changer In: since the amp is connected to the head unit's AI-Net port, a changer is connected to the AI-Net changer input on the amp
    • AI-Net: analog signals are input through an AI-Net cable; the amp has no standard RCA inputs
    • Guide Input: single RCA input
    • Subwoofer: single RCA output
