HSP SERIES INSTALLATION AND OPERATION MANUAL
REAR PANEL
1
Mains Input Connector
Your amplifier is fitted with a standard IEC 60320-C14 socket for mains
connection. Use the mains cable supplied to power up the unit.
NOTE:
Your unit must always be earthed!
2
Speaker Outputs
The class D amplifier output features 100V Line, 70V Line or 4 Ohm low
impedance operation.
IMPORTANT
: Remove the speaker connector link if operating the amplifier
in 4 Ohm operation.
NOTE:
Only one output type should be used at a time.
3
RS232 Communications Port
The RS232 port is designed to be connected to an external control system or to
a remote PC. Using an RS232 converter (not supplied), connect to this port to
communicate with the amplifier from the PC software application or via serial
commands. The PC software application allows for real time monitoring and
configuration of the amplifier.
Consult the Software Control Over RS232 setup section of this manual for
further details of this control.

External Mute, Standby and Fault
External Mute
Connect this input to ground (GND) to mute amplifier channels.
Consult the
External Mute
section of this manual for further detail of this
control.
Standby
Connect this input to ground (GND) to enable standby mode.
Consult the
Standby Input
section of this manual for further detail of this
control.
Fault
This active low output indicates a fault in the amplifier. There are two possible
faults that can be indicated:
•
The amplifier has gone into thermal shutdown due to a measured high
temperature
•
The amplifier has detected an overload condition on the speaker terminals
Consult the
Fault
section of this manual for further detail of this control.
5
Input Channel Clip LEDs
The input channel clip LEDs are used to indicate that the input signal is being
clipped. If the input is clipping, reduce the signal by turning the attenuation pot
counter-clockwise (when viewed from rear) until the clip LED ever so slightly
turns on with an input source present.
The input source should be representative of the audio that will be used in the
system on a daily basis.
