Description car amplifier Alpine R-A75M

The Alpine R-A75M Car Audio Amplifier is a state-of-the-art Class D single-channel amplifier with excellent performance. Alpine offers an improved series of amplifiers that are specifically designed to work with the R-Series speakers. They are highly resistant to high temperatures and do not turn off due to overheating. The new 1-channel amplifier boasts an impressive power of 1500 watts, and in addition, it complies with Hi-Res Audio standards.

Original digital design
Small case and powerful sound: the new design of the digital amplification system makes it possible to obtain high power output, while maintaining the rather small dimensions of the amplifier-only 274 mm wide and 223 mm long. This model is easy to install on almost any car.

Overheat protection
Along with the updated proprietary intellectual platform, the new R-series amplifiers have an improved radiator design and a protective circuit that completely eliminates shutdown due to elevated temperature, which significantly increases the reliability of the device.

Bass control with a special filter
The presence of the Bass EQ function allows you to enhance the bass reproduction by 50 Hz to +12 dB when setting the bass signal. In addition, the presence of an ultra-low-pass filter before amplification removes the lowest frequencies. Due to this, the speakers are protected from reproducing sounds in the ultra low range, which minimizes the loss of energy when reproducing frequencies that are not audible to the human ear. It also provides extra protection for subwoofers.

Low and high level inputs
There are 4 linear RCA inputs to which you can connect both a standard singal and a high and low level signal. This provides easy connection of the amplifier directly to any car audio system, regardless of the outputs that the head unit is equipped with. Thick cables up to 4 AWG can also be connected to the power cable terminal.

Subwoofer control
You can connect the RUX-KNOB2 remote bass control to the amplifier (not included, sold separately) to control the subwoofer level directly from the dashboard of your car.

Hi-Res Audio Compatibility
The amplifiers in this series use the innovative Alpine platform, based on the Class-D amplification scheme. Double feedback is added to it, which is connected after the output filter. This ensures that the result is very accurate and controlled sound. This technology ensures the amplifier is compatible with the high requirements of Hi-Res Audio.
