Overview
The BG-AMPC40 is a 40-Watt digital stereo amplifier (Class-D) with switchable output of 70V or 100V. Inputs include 2 stereo inputs (1×3.5mm port for line in, 2xRCA for L&R), 1 TOSLINK input, and 1 balanced MIC input. The 3-pin MIC input has selectable 48V phantom power, supports balanced or unbalanced signals, and features external noise suppression.
Integrated functions include ducking, EQ control, and MIC mixer. The rotary knob allows users to choose from 16 IR ID codes for easy control of multiple amplifiers. The front panel has controls for input selection, volume level for MIC and Line inputs, and bass/treble adjustment. This amplifier can be controlled with RS232 commands in addition to the front panel buttons and IR commands.

Interfaces
1. Audio Input Selection: Press the INPUT SEL button to select an input audio source, After choosing an audio source, the corresponding LED indicator will illuminate. No.1 is for dual mono audio input (2 RCA connectors for L&R), No.2 is for stereo audio input (3.5mm mini jack), and No.3 is for digital fiber audio input.
2. Audio Control: Select the MIC, Line, Bass, or Treble with this button to then be able to control their volume levels.
3. Volume Adjustment: To turn up, down, or mute the selected audio. ▽: Turn down the volume △: Turn up the volume MUTE: Mute the output.
4. Power Indicator: Illuminates red when power is connected.
5. Microphone input port: 3-pin phoenix connector for microphone input. The switch on the right side is used to select the input type: 48V (for condenser microphone), MIC (for dynamic microphone), and LINE (for line audio).
6. Audio Inputs: 3.5mm mini jack for stereo audio input. It can be connected with audio source devices (e.g., DVD player).
7. ID Code: Turn the dial to select 1 of 16 codes which range from 0 to F (hexadecimal). It is used to manage multiple units with PC control software.
8. IR: To connect with the IR receiver. Increases the range of the IR remote if the main unit is out of line of sight.
10. L+R RCA: Dual-mono audio input.
11. Digital Audio Input: Fiber connector for digital audio input (PCM format only).
12. RS-232: 3-phoenix connector for serial control. It can be connected with a PC to control the amplifier.
13. Audio Output: To connect with audio output devices such as speakers (to select 70V or 100V depends on the input voltage of the speakers). COM is for grounding (GND).
9. Power Port: Connect with the power adapter (DC24V).
