D.I. Level 

– Controls the level being sent from the XLR balanced output

jack. We suggest setting the control at approximately 12 o’clock initially. If
the signal to the board is too hot, it’s better to engage the Input Pad on your
channel of the board than to turn it down here, if at all possible. In general,
it’s better (in terms of signal-to-noise ratio and dynamic presentation) to
send as hot a signal as possible to the board. However, you can adjust the
signal level, if necessary, so make sure your soundperson or recording
engineer is aware of this capability.

Ground Lift Switch 

– This switch lifts the ground within the balanced

output system to allow you to eliminate excessive noise/ground loops when
connected to external systems.

Mono Pre-EQ Effects Send/Return 

– These standard _ inch jacks allow

you to send and receive your signal to and from external devices. This
effects loop is positioned post (behind) the compressor and before the
Enhance control and the tone section. This loop is at line level; do not use
instrument level effects in this loop as they tend to be overloaded by the
higher signal level which can cause distortion.

Stereo Post-EQ Effects Send/Return

 – These standard _ inch jacks allow

you to send and receive your signal to and from external devices. This
effects loop is positioned post (behind) the tone section. This loop is at line
level; do not use instrument level effects in this loop as they tend to be
overloaded by the higher signal level which can cause distortion. To use
with mono effects, return the signal to the Left return.

Tuner Out Jack 

– This standard _ inch jack is designed to provide a pre-

gain signal for connection to a tuner. It can also be used to provide pre-tone
signal to other devices such as a direct box or console. The signal is enough
to provide adequate signal to virtually every tuner on the market.

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 WT800B 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.
