Aux. Input -
This standard _ inch input jack is designed to accept the signal
from an external source such as a CD or cassette player, drum machine,
synth. module, etc. The signal is summed (added in) prior to the tone
controls and Master Volume control. This jacks can also be used to return a
studio cue signal, allowing the WT800C to provide you with your own
headphone mix in the studio. The Aux signal is summed with the main input
and sent to all outputs, including the DI.
Right/Low Amp Output
– These consist of two _ inch jacks and an NL-4
connector (sometimes called a Speakon). The jacks are wired in parallel. The
total speaker load impedance should not go below 2 ohms. On NL-4
connectors, we use +1, -1 connections.
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 an AGC (Automatic Gain Control) circuit if the
operating temperature goes above 200 degrees F. This circuit will
automatically turn down the output of the system in the event of overheating.
It will automatically reset itself to full power 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!
OPERATING INSTRUCTIONS
Mechanical and Thermal Issues
– During operation, your amplifier should
always be placed away from sources of moisture or heat. Care should be
taken not to obstruct the ventilation holes on the bottom and sides of the
unit. In the event of thermal shutdown, you should eliminate the cause of the
thermal problem (poor ventilation, speaker loads lower than 2 ohms
PER
CHANNEL
) immediately. The supplied rack ears can be used to install your
amplifier in a conventional equipment rack for protection during
transportation.
