1. Introduction
AMPMA40X is a compact-size digital amplifier (Class-D) with 3 inputs(2 line in and 1
balanced MIC). It is integrated with powerful functions, including bridge connection,
dual-mono, EQ control, microphone mixer etc.
It has a good application in different places, including classroom, small meeting room,
lecture hall, bar, pub etc.
2. Features

Two stereo audio inputs, switchable by button, IR remote & RS232.

Volume/Bass/Treble controllable by buttons IR remote & RS232.

2x20Watt@4Ohm as the default amplifier output.

Line audio output at 3.5mm jack, with volume controllable.

Bridge connection function. User can switch the AMPMA40X to be 1x40Watt@8Ohm
by bridge connection.

Dual-mono function. User can sum up the stereo audio to two times mono audio.

MIC mixer function. The microphone will be mixed to the line audio output, and
be controlled separately.

MIC input supports 48V phantom power, dynamic MIC and wireless MIC.

MIC port can support balance/unbalance signal, suppress the external noise
effectively.

Auto noise gate. It keeps detecting the audio and MIC input, will mute the output
when there is no input.

Ultra low inrush current, no need for power sequencing. This allows multiple
AMPMA40X to be powered on simultaneously without overloading power
circuits.

Convection cooler, fan is not needed.

Antistatic case design: providing good protection for long-term and stable performance

LED indicator, for power and working status.
