then be sure it is properly seated (all the way in) when inserting the cable into the 8-pin DIN receptacle and the footswitch.
NOTE: NEVER force an improperly aligned cable! It can be connected easily when properly aligned.
NOTE: It is good practice to secure the Footswitch cable so that it will not be stressed should someone step on, trip over or pull the
cable sideways in some manner. This could cause damage to the pins on the male end of the cable or even possibly the sleeves
within the DIN jack. The simple, time tested gaffer's (duct) tape is a good idea even if you and your band mates don't move around
much during performance – someone else might.

NOTE: IMPORTANT! NEVER UNPLUG THE SPEAKER LOAD (Cabinet) WHILE THE AMPLIFIER IS IN USE AND BEING PLAYED!
The following are some basic Speaker Cabinet setup guidelines to follow for the proper loading, highest power headroom and tight,
punchy Tone.
One 8 Ohm Cabinet should be connected to the 8 OHM SPEAKER OUTPUT.
Two 8 Ohm Cabinets should be connected to the two 4 OHM SPEAKER OUTPUTS.
One 4 Ohm Cabinet should be connected to one of the 4 OHM SPEAKER OUTPUTS.
The three wiring schemes above cover 90% of the Cabinet load scenarios you will encounter. If you are attempting to connect cabi-
nets in a configuration not listed above, please consult the SPEAKER IMPEDANCE MATCHING AND HOOK-UP GUIDE toward the
end of this manual. If you are still unsure of the proper connection, DO NOT GUESS – play it safe! The PRODIGY is a high power
amplifier and improper speaker impedance connections can cause excessive tube wear or premature tube failure and other poten-
tially expensive and time-consuming damages not covered under warranty due to misuse.
NOTE: IMPORTANT! DO NOT USE A 2 OHM LOAD ON THE PRODIGY. IT WILL CAUSE STRESS ON THE OUTPUT TRANS-
FORMER AND OUTPUT TUBES, CREATE EXCESSIVE HEAT AND WEAR THE POWER TUBES FASTER OR CAUSE THEM TO
FAIL PREMATURELY.

An optional PRODIGY Footswitch is available that provides remote control of the VOICE,

tune your instrument silently without going back to your amplifier. The VOICE button allows you to toggle
the VOICE feature from Mode (position) 1, 2, 4 and 5 back to the "Bypassed/Flat" setting of Mode #3.
The female 8-pin DIN receptacle is for the optional PRODIGY Footswitch. Connect the 8-pin DIN cable
to this receptacle when the PRODIGY Footswitch is to be used to control the MUTE, VOICE, LOOP and
SOLO. Make sure the cable is oriented correctly - with the pins lining up with the sleeves in their jacks and
