If the fuse should fail. IT MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair. WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. GROUND SWITCH (3) Three-position rocker-type switch which, in most applications, should be operated in its center or zero position. There may be some situations when audible hum and/or noise will come from the loudspeaker. If this situation arises, position the ground switch to either positive or negative (+ or -) or until the noise is minimized. NOTE: Should the noise problem continue, consult your Authorized Peavey Dealer, the Peavey Factory, or a qualified service technician THE GROUND SWITCH IS NOT FUNCTIONAL ON 220/240 VOLT MODELS. SPEAKER OUTPUTS (4) The VTM features the capacity to deliver full power (VTM-60 gives 60 watts/VTM-120 gives 120 watts) into 16-. 8-, or 4-ohm loads. This is accomplished by using the correspondingly labeled speaker jack(s). These jacks are configured in a switching jack circuit which automatically selects the correct output from the multi-tap output transformer. When independent cables are used with each enclosure, the patch sequence is as follows: one 16-ohm enclosure patches into the 16-ohm jack; the second 16-ohm enclosure patches into the 8-ohm jack; the third 16-ohm enclosure patches into the 4-ohm jack, and so on up to four enclosures maximum. NOTE: The fourth speaker jack should not be utilized unless four 16-ohm enclosures are patched into the VTM with independent cables for each enclosure. When speaker enclosures are "daisy-chained'’ (connected from enclosure to enclosure and only one cable is patched into the amplifier), the procedure is as follows: two 16-ohm enclosures patch into the 8-ohm jack; three 16-ohm enclosures patch into the 4-ohm jack; four 16-ohm enclosures patch into the 4-ohm jack. NOTE: Applications requiring four 16-ohm enclosures should be connected with four independent cables from the amplifier, jacks one through four for best results. HUM BALANCE (5) A control to minimize hum. To adjust, first make sure that nothing is plugged into the amp but the speaker cabinet. Turn the uniton and set the Pre Gain and Post Gain controls at 7 While listening to the speaker closely, gradually rotate the Hum Balance control using a screwdriver until hum is at a minimum. This procedure is required periodically. Reset Hum Balance after tube change. BOOSTER OUTPUT/REMOTE STANDBY (6) A preamp out signal which can be routed to another power amp. When placing a one button on/off switch in this jack it can be used as a remote standby. NOTE: VTM-60 back panel identical except for Fuse Rating (3 amp).
