carefully chosen to allow continuous power output performance while still protecting the power trans- former. Normally, these breakers should not trip unless there is a fault in the amplifier circuitry that draws excessive mains current. However, abnormal conditions such as a short circuit on either or both channels, or continuous operation at overload or clipping (especially into 2 ohm loads) will cause the breaker to trip. If this occurs, turn the power switch off, then simply reset the breaker and correct the cause of the overload.
When tripped, the button on the breaker will be outward nearly l/2” and can be reset A by pushing inward. A normal reset button length is about l/4”. If this “thermal” type
breaker does trip, simply pushing the button back in will reset it, after waiting a brief period of time to allow it to cool down. REMEMBER, ALWAYS TURN THE POWER OFF BEFORE RESETTING THE BREAKER. If the breaker trips instantly each time you attempt to reset it, the unit should be taken to a qualified service center for repair.

DDT SWITCH (5)
This switch is used to either Enable or Defeat the DDT compressor. Normally the DDT function should be enabled to minimize the possibility of either or both channels going into clipping or overload. With DDT defeated, a severe overload could cause the mains circuit breakers to trip as a matter of course. (The Peavey DDT compression system will be covered in greater detail later in this manual.)
MODE SWITCH (6)
This switch is used to select either Stereo or Bridge mode of operation. Care should be exercised whenever the Bridge mode is selected. Accidental selection of this mode could damage loudspeakers, particularly in biamped systems. (The Bridge mode will be covered in greater detail later in this manual.)
INPUT GAIN (7)
These controls are used to adjust the input gain of each channel. Thus, they determine how “loud” each channel of the power amplifier will “play”for a given input signal level. Maximum input gain (minimum sensitivity rating) is achieved at the full clockwise setting, and this setting yields maximum mixer/system headroom. A setting of less than full clockwise will yield lower system noise at the expense of mixer/ system headroom.
