for a nominal fee and you can call us Direct and order one. You may also order one through your local MESA Dealer.
NOTE: Use an unshielded cable for the LOOP EXT. SWITCH function.
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 STRATEGY or other power amp for large venues
The primary application for the SLAVE is to add additional power while using just the one STRATEGY preamp. It is com-
mon practice to use the SLAVE jack to feed the FX LOOP RETURN jack of other 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 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 ampli-
fiers or effects..
SLAVE LEVEL (ABOVE REAR PANEL ON TUBE DECK)
This control determines the signal level at the SLAVE Jack. The
SLAVE captures the entire sound of the amplifier from the SPEAKER OUTPUT jacks and is padded down to create an optimum
signal level for insertion into the INPUT of other Power Amps. .This allows additional STRATEGY “slave” amps to be used as support
power for larger Concert venues by connecting to their FX LOOP RETURN and using only the power section leaving you with just
one preamp to navigate.
The SLAVE may be used to feed consoles as well—but the signal is hotter than that of the DI OUTPUT and not voiced with any speak-
er simulation. We suggest using the DI OUTPUT for Console interfacing whenever possible as it is better suited for this application.
NOTE: IMPORTANT! No matter what application you intend to use the SLAVE OUTPUT for—begin with the SLAVE LEVEL all
the way down—and increase the SLAVE LEVEL SLOWLY to reach an appropriate signal level for your needs. Failure to follow this
scheme could result in damage to surrounding equipment and your ears!
NOTE: The SLAVE is NOT a DI OUTPUT. Use the DI OUTPUT for all Console interfacing needs whenever possible as the SLAVE is
not optimized for this application.
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.
You may mute the audio signal at the SPEAKER OUTPUTS by using the TUNER MUTE function on the optional STRAT-
EGY 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.
