wired in SERIES with the signal. This means that the entire signal goes through the LOOP. The SEND jack will feed the signal out of
the preamp without interrupting it. The RETURN jack will break the path and interrupt the signal.
When nothing is plugged in to the SEND and RETURN jacks the EFFECTS LOOP is effectively bypassed and the signal is unaffected
by any loop circuitry. Because these jacks are stereo-type jacks and have two elements in them, be sure you firmly seat the cables
all the way in to the base of the "Ring" (shaft part) on the ¼" phono plug to ensure a good connection.
NOTE: DON'T COMPROMISE YOUR TONE! The EFFECTS LOOP is wired in SERIES with the dry signal. Use the best quality
processors and pedal effects possible in the EFFECTS LOOP to ensure a good impedance match and minimal signal degradation.
Also use the best quality (low capacitance) cable possible of the shortest length to minimize the loss of high end or punch (TONE).
We suggest 1-3 feet of FX related cabling, at most, to preserve tonal integrity. Everything you put in your signal path affects your
sound – so use the best!

TUNER

This jack captures the sound of your Instrument right off the INPUT jack - before it enters the preamp - and sends it
directly to the TUNER output providing a feed for tuning devices. It is a buffered signal so longer cable lengths are not an issue.

OUT
SLAVE
This jack is the output for the SLAVE circuit. Its signal is derived from the SPEAKER OUTPUT and then padded down
substantially to optimize it for driving additional amplifiers such as an additional PRODIGY or other power amp for large venues

accordingly and the signal level is on the hot side. Use the D.I. OUTPUT whenever possible for interfacing to Consoles as you will
achieve better results.
NOTE: IMPORTANT! Always begin using the SLAVE by setting the Front Panel MASTER to 7:30 (OFF) and increase it slowly as
this approach will help protect INPUT Stages, Speakers and most importantly... Ears!
NOTE: Once a signal is taken out of the SLAVE OUT it can not be inserted back into the amplifier anywhere as a feedback loop will
occur, producing a loud squeal akin to holding a microphone up to the PA Speaker.
NOTE: Use only shielded high quality (low capacitance) audio cable when taking a signal from the SLAVE OUT to other power
amplifiers or effects..
You may mute the audio signal at the SPEAKER OUTPUTS by using the TUNER MUTE function on the
optional PRODIGY Footswitch or, by triggering the MUTE feature via the EXT. SWITCHING jacks with an
external master switching device or a single tip-to-ground on/off latching footswitch.
NOTE: Use shielded audio cable for connecting the TUNER Output to an external tuner.
The primary application for the SLAVE is to add additional power while using just the one PRODIGY
preamp. It is common practice to use the SLAVE jack to feed the EFFECTS LOOP RETURN jack of
other PRODIGY or STRATEGY amplifiers and bypass their preamps. This scheme provides minimal
"tweaking" when you want to add power and also allows for a backup preamp should you ever need one
(tube failure, etc.).
While it is possible to feed Mixing Consoles with the SLAVE, it is not recommended as it is not voiced
