Mains On/Off Switch
– This switch turns the system power ON or OFF.
The switch illuminates to indicate the presence of AC power present in the
chassis. This switch is prior to the fuse. The light in the switch may flicker
depending on local voltage conditions. This is normal and nothing to be
concerned about.
NOTE: The Mains Switch will illuminate even if the fuse is blown.
However, the DC Indicators will not illuminate if the fuse is blown.
IMPORTANT NOTE:
When attached, the included lighted footswitch will
defeat the Front Panel controls for the Mute to Tune and Enhance Bypass
functions.

Cooling System
– Your amplifier features a thermostatically controlled fan,
which will switch on when the internal temperature reaches 130 degrees F.
In low volume situations (into 8 Ohm loads) the fan may not come on at all.
The cooling system also features a high temperature thermal safety system,
which will activate a circuit if the operating temperature goes above 200
degrees F. This circuit will automatically turn off the output of the system in
the event of overheating. It will automatically reset itself as soon as the unit
cools down to a safe operating temperature.
NOTE
: the D.I. will continue to operate normally even when the amplifier is
in thermal safety mode. Only the stage sound will be lost.
IMPORTANT NOTE: Excessive heat is a Very Bad Thing and can
result in severe damage to your amplifier. DO NOT bypass or
disconnect any part of your thermal safety system. Doing so will
immediately void your warranty!
