1. Introduction

1.1 Introduction to AMV-340

AMV-340 is a 40 Watt Power Amplifier (Class-D) with output alternatively at 70V or 100V.
It has 2 stereo inputs (1x3.5mm jack for line in, 2xRCA for L&R), 1 digital input & 1
balanced MIC. It is integrated with powerful functions, including ducking function, EQ
control, MIC mixer etc, and MIC input supports 3 levels with condenser MIC, dynamic
MIC & line audio input.

As for power amplifier we have normally voltages at 70V and 100V for different countries,
but AMV-340 is designed to integrate with both voltages to meet different requirements.

1.2 Features

 Mono audio output at 40Watt.
 Switchable between 70V and 100V.
 Ducking function.
 16 ID codes for controlling between different AMV-340 amplifiers.
 3-level MIC input, supports condenser microphone, dynamic microphone and

wireless microphone.

 MIC port can support balance/unbalance signal, suppress the external noise

effectively.

 Two stereo audio inputs and one digital audio input, switchable by button, IR remote

& RS232.

 Volume/Bass/Treble controllable by buttons, IR remote & RS232.
 Fast switching speed for good performance.
 Convection cooler, fan is not needed.
 LED indicator, for power and working status.
 Antistatic case design to provide good protection for long-term and stable

performance.
