Bridging Switch
The Scamp features an internal bridging function which can be activated with this
switch.
Gain Control
Use this to adjust the volume level when an external preamplifier is not being used.
Using USB digital
Connect your personal computer via an A to B type USB cable. The Scamp will
automatically be recognised by the computer as a USB DAC. Using the sound options
on the computer you can select the USB DAC sound device to output audio to the
Scamp.
Using the Bridging Function
When the bridging switch is pressed the Scamp becomes a high power mono
amplifier. When using this mode the connections need to be made differently. Only
one input is required this can be left or right depending on which speaker you want to
connect to. The speaker then connects to the red terminals only. The positive speaker
connection should go to the right red terminal and the negative speaker connection
should go to the left red terminal. Do not connect to the black binding posts. Repeat
this procedure for the other amplifier. You will now have two bridged mono block
amplifiers with an 80W output.
Automatic Overload shutdown
If the Scamp is overdriven or the volume is turned up too high then the amplifier will go
into shutdown mode where the music will sound quieter and distorted. This is to protect
both the amplifier and speakers. Simply reduce the volume until you can hear the music
clearly again.
