.
(1) Power Switch
This switch controls the power supply to the amplifier. There is a short delay on power-up,
this is to avoid switch-on "thump" which could damage the loudspeakers.
.
(2) Gain Controls
The level of each Channel is individually adjusted by these controls.
Rotating these controls fully clockwise, results in no attenuation to the incoming audio signals.
.
(3) Indicator Section, Status:
a. Power Indicators
This indicator shows when the amplifier is on and each channel is receiving power.
b. Protect Indicators
These indicators light briefly during the power up cycle and also light should a
fault occur. Illumination of the protect indicators, shows that the output of the
amplifier has been disconnected by means of an internal relay to protect
connected speaker systems from being damaged by the fault.
(4) Indicator Section, Signal levels:
a. Output Level Display
These show the (Peak) output level of the amplifier for each channel.
Note: It is useful to remember for trouble shooting, that the sensors for the
Output Level Display, detects levels after the output relays. Therefore if the
display is operating, a signal is present at the speaker sockets when driven above a threshold of
approximately -9db. Also note that when operating signal level is low, the led may not
illuminate. In this instance observe signal presence either by increasing volume until led
illuminates, or listen to speaker output to verify correct operation. For further information on the
signal lights and how they relate to the power the amp is generating please visit
