A
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 properly grounded receptacles.
SPEAKER OUTPUTS (6)
A
Provided for connection of external speaker(s). Minimum total impedance is 4 ohms.
DDTTM
COMPRESSION (7)
Each of the two internal power amplifiers is equipped with Peavey’s patented
DDTTM
Compression. The
DDT circuits will automatically engage to prevent clipping distortion within the power amplifiers. Compres-
sion is defeated when the pushbutton is “in”.
DDTTM
should be enabled at all times to protect speakers.
INPUT SENSITIVITY (8)
Maximum input gain (minimum sensitivity rating) is achieved at the full clockwise setting. A setting of less
than full clockwise will yield lower system noise at the expense of headroom. Calibration indicates sensitivity
in
volts/dBV
necessary to attain full available output.
OPERATION NOTE: The input sensitivity rating of a power amplifier is the voltage level required to drive the
amplifier to full output.
CHANNEL INPUTS (9)
Standard
l/4”
phone jacks with a special switching function to allow two modes of operation:
a. For normal STEREO operation, each jack is used as the input to the respective channel
(see fig. 1).
b. For dual-channel MONO operation, the A input jack may be used by inserting the plug only to the
first “click” or detent (see fig. 2). In this mode, the signal source is applied equally to both
channels.
