GROUND SWITCH (24)
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 -)
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.
AC LINE CORD—120 V PRODUCTS ONLY (25)
For your safety, we have incorporated a three-wire line (mains) cable with proper grounding
facilities. It is not advisable to remove the ground pin under any circumstances. If it is
necessary to use the equipment without proper grounding facilities, suitable grounding adaptors
should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with
the proper grounded receptacles.
(For UK Only) As the colours of the wires in the mains lead of this apparatus may not correspond
with the coloured markings identifying the terminals in your plug, proceed as follows:
• The wire which is coloured green and yellow must be connected to the terminal which is marked
by the letter E or by the earth symbol, or coloured green or green and yellow.

N or coloured black.
• The wire which is coloured brown must be connected the terminal which is marked with the letter
L or the coloured red.
