with AC power supply. The Power and DC LED shall light up when in use of Battery Backup.
Fault LED On/Off:
Enable/disable the Fault Power LED indicator. In need of turning off the indicator, use a thin
screwdriver to press the retractable button.

Channel 1/2 Outputs:
Each channel outputs a replica of the corresponding balanced audio input signal either on the XLR
connector or on the Euro-terminal block.
The following table lists the pins of XLR connector(Female and Male):
Item
Description
Pin1
Chassis ground (cable shield).
Pin2
Positive polarity terminal for balanced audio circuits (aka "hot").
Pin3
Negative polarity terminal for balanced circuits (aka "cold").

Channel 1/2 Inputs:
For each channel, there is an XLR balanced input and a Euro-terminal block balanced input. Each
input gain control can be adjusted to suit the users’ needs. The ON/OFF gain switch can
instantaneously bypass the gain controller and set the channel gain amplifier to maximum.
AC Power Socket:
Main 230V~253V, 50/60Hz AC power input with fuse. It accepts a standard mains power lead fitted
with an IEC connector.
Channel 1/2 Audio Output:
For each amplifier channel, there is a dedicated Audio Output connector for connection of either 8
Ohm speakers, 50V speakers or 100V speakers. For the 8 Ohm connection and if you are using more
than 1 speaker, please ensure that speakers are wired in a way that the total impedance load is
between 8 Ohm and 16 Ohm. The Com point is the negative terminal and 8 Ohm, 50V and 100V are
the positive terminals.
Fault Contact:
The fault contact indicates an amplifier fault by an opening contact.
Channel 1/2 Inputs GAIN and ON/OFF switch:
The ON/OFF switch is mainly for the parallel output and the knob is for adjusting the amplifier gain.

Parallel & Bridged Output/Installation
To combine 2 or more channels into one. For example, 120W x 2 Channels to be one channel with
240W power, see the listed description below:
BPA-2120 (120W x 2 Channel to be 240W power)
BPA-2240 (240W x 2 Channel to be 480W power)
BPA-2480 (480W x 2 Channel to be 960W power)
Parallel Output:
1. Turn the input gain to "OFF" position on channel 2, but keep the channel 1 Input gain adjustable.
