Power (standby switch)
The LED above the switch illuminates when the power is
on. When it is switched off here, the amplifier remains in
standby mode with certain sections of the amplifier still
operational. When the preamplifier is switched on, the ON
LED will also illuminate. If you do not intend to use the
preamplifier for a while, switch the unit off using the on/off
switch on the outboard power supply.
Muting gain switch
This rotary switch has two functions and three positions.
First, it changes the gain of the line stage. The setting is
shown by the "low" and "high" LEDs. You can also use this
switch to activate the muting function. The LED above the
switch illuminates when the muting is on.
The muting function short-circuits the preamplifier outputs.
Use the muting feature whenever you plug or unplug cables
to or from the preamplifier, as it isolates the preamplifier
outputs from the power amp, allowing you to swap cables
without switching the preamplifier off.
When using the muting function, you should also turn
the volume control to zero.
Use the low/high gain setting to adjust the preamp output to
suit the efficiency of your loudspeakers and increase the
sensitivity of the volume control.
When you change the position of the switch, the muting
function automatically activates to avoid sending
switching noises to your speakers.
