Alpine Status HDA-V90 - 5-Channel Amplifier

The Alpine HDA-V90 5-Channel Power Amplifier features a Class-D amplification circuit with Sierra-H technology (see below for more details on Sierra-H). It features an RMS power output of 4x 75 Watts + 1x 300 Watts @ 4Ohm, 4x 100 Watts + 1x 500 Watts @ 2Ohm or 2x 200W @ 4Ohm bridged and a frequency response of 10Hz to 60kHz (channel 1-4) and 8Hz – 400Hz (channel 5).

If you want to build a full Alpine Status sound system with external amplifiers, we recommend the Alpine Status Class-D amplifiers. These amps are developed to perfectly match the Alpine Status speakers and subwoofer for best sound quality. There is a Mono power amplifier (HDA-M80), a 4-channel amplifier (HDA-F60) and a 5-channel amplifier (HDA-V90) with a dedicated high-power subwoofer channel.

All controls are conveniently located on the top side of the amplifiers, protected by a cover plate. This gives you easy access to HP / LP filters and frequency adjustments, gain controls and input channel selectors (different for each amplifier model).

Product Features

Excellent Sound Quality

Alpine Status amplifiers feature many audiophile technologies and selected high-end components to reproduce excellent sound quality. A copper shield keeps electromagnetic interferences away from the black PCB board, to ensure best audio reproduction. The Signal to noise ratio is >87dB (channel 1-4 1W into 4 Ohm) and >80dB (channel 5 1W into 4 Ohm).

Sierra-H Circuit

After the original analog sound wave is converted to a digital signal and amplified, the Sierra-H circuit compares and corrects the amplified signal with the original waveform twice, to reproduce a highly accurate signal without any gaps.

One-Sided Terminal

All connections (power supply, speaker outputs, RCA inputs / outputs and the remote bass knob connector), as well as all fuses are located on the down-side of the amplifier. This makes it much easier to achieve a clean installation in your vehicle. You can connect the RUX-KNOB2 for subwoofer level control (in bridged mode channel 3 + 4).

Thermal Protection

Along with Alpine’s new intelligent amplifier platform, the new Alpine Status amplifiers feature an improved heat sink and protection circuit design that eliminates thermal shut-down, for dependable music playback.

Studio Recording Spec

Alpine Status achieves 192kHz/24Bit playback, which is 6.5 times the amount of digital audio data in a standard CD or digital streaming service and exceeds the standard High-Resolution spec of 96kHz/24Bit found in most aftermarket sound solutions. This allows Alpine Status to capture and accurately reproduce details like the breath of the artist or a musician’s subtle interaction with an instrument. This capability not only reproduces music to the artist’s original intention, but emulates the experience of a studio recording in the vehicle.
