COMPRESSOR ON/OFF SWITCH
This button switches the compressor on and off.
VOLUME
This knob controls the overall volume of the amplifier.
DDT
™
(Distortion Detection Technique)
This button prevents power amplifier clipping that can damage speakers. Although this feature can be
activated or bypassed by this switch, Peavey
®
recommends the DDT stay enabled for optimum system
performance.
HEADPHONE OUTPUT
1/4" headphone output for personal monitoring.
DDT INDICATOR LIGHT
When DDT is enabled, the Protect/Clip LED will flash when DDT is triggered. This is normal. However,
if the LED is constantly illuminated, the gain level needs to be reduced to prevent possible equipment
damage. When DDT is defeated, the LED becomes a clip indicator. The DDT LED indicator is also a fault
indicator. If the amp is overheating, this LED will light up red and the amp will produce no sound. In this
case, the user needs to stop playing and allow the cooling fan to cool the amp down before continued
use. When the amp has returned to normal operating temperature, the light will turn green again. Also,
the user needs to verify that they are not exceeding the 4 ohm load limit and that the cooling vents are
free from obstruction. The other fault condition is when the output short protection is activated either
by a shorted speaker cable or by exceeding the 4 ohm load limit. If the LED stays red all the time, the
amplifier needs to be taken to an authorized Peavey service center immediately for service.
POWER SWITCH
To apply power to the unit, flip the switch to the “ON” position. The green LED will illuminate, indicating
that power is being supplied.
Caution:
The Power switch in this unit does not break both sides of the primary mains.
Hazardous energy can be present inside the chassis even when the Power switch is in the
"OFF" position.
AC POWER INLET:
This is the receptacle for an IEC line cord, which provides AC power to the unit. Connect the line cord to
this connector to provide power to the unit.
Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does
not have a ground pin, a suitable grounding adapter should be used, and the third wire should be
grounded properly. To prevent the risk of shock or fire hazard, always make sure that the amplifier and
all associated equipment is properly grounded.
