INTRODUCTION & CONTENTS
INTRODUCTION
ANI-PA is a compact-size digital amplifi er (Class-D) with 3 inputs (2 line level and 1 MIC). It is integrated with many useful functions,
including Volume control, bridge connection to additional ANI-PA’s, dual-mono, EQ control, microphone mixer, etc.
It is designed for use in many different applications, including classrooms, small meeting rooms, lecture halls, bars, etc.

FEATURES
FEATURES
1. Two stereo audio inputs, switchable by push-button, RS-232 & IR remote (optional).
2. Volume/Bass/Treble controllable by push-button, RS-232 & IR remote (optional).
3. 2x20Watt@4 Ohm as the default amplifi er output.
4. Line audio output at 3.5mm jack, with volume controllable.
5. Bridge connection function. User can switch the ANI-PA to be 1x40Watt@8Ohm by bridge connection.
6. Dual-mono function. User can sum up the stereo audio to two times mono audio.
7. MIC mixer function. The microphone will be mixed to the line audio output, and be controlled separately.
8. MIC input supports 48V phantom power, dynamic MIC and wireless MIC.
9. MIC port can support balance/unbalance signal, suppress the external noise effectively.
10. Noise gate function. It keeps detecting the audio and MIC input, will mute the output after 10 seconds when there is no input.
11. Ultra low inrush current, no need for power sequencing. This allows multiple ANI-PA to be powered on simultaneously without
overloading power circuits.
12. Convection cooled, a fan is not needed.
13. Antistatic case design: providing good protection for long-term and stable performance
14. LED indicator, for power and working status.

AUDIO CONNECTION
AUDIO OUTPUT
Default Output: 2x20Watt@4 Ohm
The default output of the amplifi er is 2x20Watt@4 Ohm, so user can connect the amplifi er in stereo. As the picture below:
Connecting all four pins.
Bridge Connection: 1x40Watt@8 Ohm
The ANI-PA has the bridge connection, to double the output power at 1x40Watt@8 Ohm. 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:
Connecting only two pins.
Dual-Mono Output:
The ANI-PA also has the function of double-mono output. It can sum up the left and right channel, to be mono audio output. In this way,
both of the outputs are showing the same mono audio.
The connection is:
Connecting all four pins.

AUDIO CONNECTION CONT’D
MICROPHONE INPUT
The microphone input of ANI-PA has three modes, and different modes use different connections, as the picture below:
48V Phantom Power Input
When the switch is set 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.
NOTICE: In this mode, only condenser microphone can be connected.
MIC Input
When the switch is set to “MIC”, the microphone input is used for connecting with dynamic microphone. There are two different connections:
1) Unbalanced connection:
a) “╧” connects to ground, and “-” connects to signal, or
b) “╧” connects to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧” connects to ground.
LINE Input
When the switch is set to “LINE”, the microphone input is used for connecting with line level audio sources. There are two different
connections:
1) Unbalanced connection:
a) “╧” connects to ground, and “-” connects to signal, or
b) “╧” connects to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “╧” connects to ground.

Input modes switch.
BUTTONS CONTROL
The buttons provides control of volume/EQ and switching.
AUDIO SWITCHING
There are two switchable stereo audio inputs, one 2xRCA input, and one 3.5mm jack input, switchable through the buttons as below:
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 control up/down/mute by the function buttons.
For example, to turn up the line volume, you fi rst select “LINE”, and then press the button “▲”.

Source Selection
Firstly to select the function
from this menu.
Then to turn down/up the
level, or mute the output.

2: The bracket [ ] is not part of the command.
3: Any dot “.” after the letters is part of the command.
Example 1:
Switch the Input 2 to the line out. RS-232 command: [2A1.]
Example 2:
Turn up the volume on line audio. RS-232 command: [603%]
Example 3:
Preset the MIC volume to “21” degree. RS-232 command: [521%]
Example 4:
Check the status of Zoom function [0608%]
To cycle thru the Zoom functions, send the command repeatedly [0608%][0608%]
