The PulseAudio PAV140 is an amplifier that produces 40 Watts with Class-D
power that is able to output 70V or 100V. Features two stereo inputs (3.5mm
jack for line in and (2) RCA for L&R), one digital input and one balanced MIC
input, with integrated ducking functionality, EQ control, and MIC mixing. The
MIC input supports three levels with condenser MIC, dynamic MIC and line
level audio input. The single output channel supports up to 40W @8ohms
and is able to be controlled manually, as well as with IR and RS232. Can
be combined with multiple amplifiers within a system, with the ability of
controlling each zone individually. The PAV140 is a great solution for any
70v/100v speaker application.

CONNECT AND OPERATE
7
1. Ensure power is o or removed from the PAV140
2. Connect an analog (3.5MM stereo or dual-RCA) and/or digital (optical) audio cable
between the audio output of the source device and the appropriate audio input
3. IF USING A MICROPHONE: Move the MIC Input Switch to the appropriate setting and
connect using the 3 conductor phoenix connecter based on the type of microphone being
used
a. 48V – 48dB gain with 48V phantom power: When the switch turns to “48V” (It
has a good frequency characteristic, high input impedance and high sensitivity in
this mode), 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
b. MIC – 48dB gain: When the switch turns to “MIC” (It has a low frequency
characteristics, and wide frequency response in this mode). The microphone input is
used for connecting a dynamic microphone. There are two dierent connections:
i. Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal or “-” and “ ” connect to
ground, and “+” connects to signal.
ii. Balanced connection: “+” connects to positive, “-” connects to negative
and “ ” connects to ground.
c. LINE – 4dB gain: When the switch turns to “LINE” (It has a low frequency
characteristics, and wide frequency response in this mode), the microphone input is used
for connecting with normal audio or wireless microphone output. There are two dierent
connections:
i. Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal or “-” and “ ” connect to
ground, and “+” connects to signal.
ii. Balanced connection:
“+” connects to positive, “-” connects to negative and “ ” connects to ground.
4. Connect the speakers according to the diagram below
5. OPTIONAL: If using IR with the PAV140-IR (sold separately), connect the IR receiver into
the IR IN port of the PAV140
6. OPTIONAL: If using RS232, connect the provided 3-conductor phoenix connector cable
into the RS232 port
a. By default, the RS232 ID selector is set to 0
b. Setting the ID selector to any of the other values will prevent the PAV140 from
accepting any RS232 commands not in the correct format.
7. Connect the power supply into the power input port
8. Power on attached audio devices and test

NOTICE
1. The letter inside bracket [ ] is the variable code, which is able to be changed
2. The bracket [ ] is not included to the actual RS232 commands
3. Any dot “.” after the letters is part of the commands
4. ID coding:
• The ID codes of 40 Watt Power Amplifier ranges from 0 to F (hexadecimal), when
sending RS232 commands, please take notice of the address of the ID code
• If the address of the ID code is 0, any RS232 command is available
• If the address is in 1~F, it has one unique ID code (If the ID code is not the same with
the address, no RS232 command will work)
• While the ID code is in 1~F, please add “ID/” before sending the command
• For example, if the ID code is 5, the RS232 command needed is “604%”, the correct
command is in this format: 5/604%
• There is no need to add “ID/” before the command when the ID code is 0
Examples:
1. Switching the input 2 to the line out, the command is: 2A1
2. Turning up the volume of line audio, the command is: 603%
3. Preset the MIC volume to “21” degree, the command is: 521%
4. Checking the working status of 40 Watt Power Amplifier, the command is: 600%
5. If the ID code is 0, sending command 601% is able to turn up the MIC volume. If the ID
code is 2, sending command 601% will not work, and the MIC volume remains unchanged. The
right command is 2/601%
