Rear Panel Layout - Sherbourn PA7-150 User Manual

Rear Panel Layout

1. Status LED Switch – Status LEDs can be turned on
and off with this switch.
2. Unbalanced / Balanced Input Selector – When turned
towards 'Un-Bal', the RCA (unbalanced) input is chosen
and active. When turned towards 'Bal', the XLR / Bal-
anced input is chosen and active.
3. XLR / Balanced Audio Input – Standard XLR input
connection that connects to a standard XLR audio output
connection on a preamplifier, receiver or multi-channel
processor.
4. RCA / Unbalanced Audio Inputs – Standard RCA in-
put connection that connects to a standard RCA audio out-
put connection on a preamplifier, receiver or multi-chan-
nel processor.
5. Master Power Switch - This rocker switch provides the
master power for the amplifier. After it is in the ON posi-
tion, the amplifier can be turned on manually from the
front panel switch or automatically with the trigger input
via 3.5mm input jack. Under normal use, this switch
should remain on, leaving the amplifier in standby posi-
tion, and coming to full power with either the front panel
'standby' button, or activation through the remote trigger.
6. Remote Trigger Input – The 7-150 can be remotely
triggered by another device, and in turn, remotely trigger
another device. When a remote trigger output from a pre-
amplifier, processor or other audio device is connected to
the trigger input here, the amplifier will power up and shut
down along with the first device. Another device (CD
player, amplifier, etc) can be added to this chain using the
tridder output. This 3.5mm jack accepts a 5-12 volt input
for remote activation of the amplifier and mates directly
with the Sherbourn processor trigger output. If building
your own cable, center is positive and outer shield is neg-
ative.
7. Speaker Outputs (5 way Binding Posts) - These are the
speaker outputs. The 5 way binding posts accept stripped
speaker wire, banana plugs (single or dual), or spade con-
nectors. Be sure to observe correct polarity when connect-
ing speakers and be sure that the wires do not touch
between positive and negative terminals.
8. Power Receptacle - This is a standard IEC 2 prong
power receptacle. It is advised that this amplifier have a
direct connection to a wall outlet. Do not plug into a
"power strip".
Note: Potentially lethal voltages present! Never connect,
disconnect or modify speaker wiring with the
amplifier turned on.
