Footswitch Jack

 – Connect the Footswitch here. When connected, the 

footswitch overrides the corresponding front panel controls. 

 
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 hot 
enough to provide adequate signal to virtually every tuner on the market. 
 

Stereo 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 WT1205 to provide you with your 
own headphone mix in the studio. 

 
Recording Out 

– 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. (

For you propellerheads, this output is buffered for up to 100 

Volts DC to protect the amplifier from phantom power supplies.

 
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 Effects Sends and Returns 

– These standard ¼ inch jacks allow you 

to send and receive your signal to and from external devices. Each channel 
has a Pre-EQ and Post-EQ loop. The Pre-EQ effects loops are positioned 
post (behind) the compressor and before the Enhance control and the tone 
section. The Post-EQ loops are positioned immediately after the tone 
controls. These loops are 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. 
 

Propellerhead Note: The Effects Loops are switched on the Return jacks. 
This allows all Effects Sends to be used as Auxiliary Sends to outboard 
equipment. This qualifies as a Really Neat Thing.
