Balanced Inputs
The balanced (XLR) inputs accept analogue audio signals from preamplifiers with balanced outputs.
The pin assignments of the balanced XLR input connectors are:
Pin 1: Shield
Pin 2: +ve signal (hot)
Pin 3: -ve signal (cold)
Please refer to the owner’s manual of your preamplifier to verify that the pin assignments of the output
connectors correspond as above. If this is not the case, wire the cables so that the appropriate
preamplifier output pin connects to the equivalent 100p input pin.
Note:
These inputs are for analogue audio signals only. They should not be connected to the AES/EBU
digital output of a CD player or any other digital device.
6
Unbalanced Inputs
The unbalanced (RCA) inputs accept analogue audio signals from preamplifiers with single-ended outputs.
Note:
These inputs are for analogue audio signals only. They should not be connected to the digital
output of a CD player or any other digital device.

Input Switch
This switch is used to select the ‘XLR’ (balanced) or ‘RCA’ (unbalanced) inputs.
8
Trigger Input
The trigger input allows the Audiant 100p to be brought in and out of standby by a remotely connected
device; for example, another audio component or a home automation system. The trigger input uses
a mono 3.5mm (
1/8
”) plug and accepts voltages of 0V DC up to 12V DC. A trigger voltage between 3V
and 12V DC will bring the amplifier out of standby and it will enter standby when the trigger voltage is
0V DC.
The trigger input plug must meet the specifications shown below:
Sleeve: GND
Tip: Signal

RS232 Port
The RS232 port allows external serial control of the Audiant 100p for custom install use. A full
command set is available on the Perreaux website. This port can also be used by authorised Perreaux
service personnel for software updates.The Coax Input is for connecting coaxial digital sources, such
as CD players, music streamers etc.
