1. Introduction
1.1.Introduction to Mini Digital Amplifier
The Mini Digital Amplifier 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.
1.2.Features
2x20Watt@4Ohm as the default amplifier output.
Bridge connection function. User can switch the Mini Digital Amplifier to be
1x40Watt@8Ohm by bridge connection.
Two stereo audio inputs, switchable by button, IR remote & RS232.
Volume/Bass/Treble controllable by buttons IR remote & RS232.
MIC port can support balance/unbalance signal, suppress the external noise
effectively.
Line audio output at 3.5mm jack, with volume controllable.
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.
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 Mini
Digital Amplifier 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.

2. System Connection Introduction
2.1.Audio Output
2.1.1. Default output: 2x20Watt@4Ohm
The default output of amplifier is 2x20Watt@4Ohm, so user can connect the amplifier
output in the regular way. As the picture below:
2.1.2. Bridge connection: 1x40Watt@8Ohm
The Mini Digital Amplifier has the bridge connection, to double the output power at
1x40Watt@8Ohm. It will sum up the input left channel and input right channel to be
mono output, and the power is up to 40Watt.
The bridge connection is:
2.1.3. Dual-mono Output
The Mini Digital Amplifier also has the function of double-mono output. It can sum up
the left and right channel, to be the mono audio output. In this way, the both of the
outputs are showing the same mono audio.
The connection is:
Connecting the two pins, like this
Connecting the four pins, like this

2.2.Microphone input
The microphone input of Mini Digital Amplifier has three modes, and different modes
use different connections, as the picture below:
2.2.1. 48V phantom power input
When the switch turns to “48V”, the MIC input will provide a 48V phantom power. This
is usually used for power supply for condenser microphone, Connection is:
“+” connects to positive, “-” connects to negative and “╧” to ground.
Note: In this mode, only condenser microphone can be connected with.
2.2.2. MIC input
When the switch turns to “MIC”, the microphone input is used for connecting with
dynamic microphone. There are two different connections:
1) Unbalanced connection:
“╧” connects to ground, and “-” connects to signal.
“╧” connects to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧”
connects to ground.
Connecting the four pins, like this

2.2.3. LINE input
When the switch turns to “LINE”, the microphone input is used for connecting with
normal audio or wireless microphone output. There are two different connections:
1) Unbalanced connection:
“╧” connects to ground, and “-” connects to signal.
“╧” connects to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧”
connects to ground.

3. Operation of the Control Panel and the IR Remote
3.1.Operation of the Control Panel
The buttons provides the control of volume/EQ control and switching. The following
content introduces audio switching and EQ control in detail.
3.1.1. Audio switching
There are two switchable stereo audio inputs, one 2xRCA input, and one 3.5mm jack
input, switchable through the buttons as below:
3.1.2. Volume/EQ controlling
The line volume and MIC volume can be controlled by the buttons.
The MIC Volume/LINE volume/LINE bass/LINE treble will be selected by the buttons,
and controlled up/down/mute by the function buttons. Please check the picture below:
