Recording Out (D.I.) – This fully balanced XLR output allows you to send
a pre- or post-EQ signal to a recording or sound reinforcement mixing
console. We use Pin 2 hot configuration. Adjusting the Master Volume
control will not affect this send. This output is designed to use with phantom
powered systems. However, it never hurts to turn off the phantom power at
the board, if possible.
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.
Aux. Inputs - These standard ¼ inch input jacks are 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. These jacks can also be used to
return a studio cue signal, allowing the WT550 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.
Tuner Out Jack – This standard ¼ 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.
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.
