FRONT PANEL FEATURES

(1)INPUT GAIN (dB)

These controls are used to adjust the input gain of each channel. They determine how “loud” each channel of the power amplifier will sound for a given input signal level. Maximum input gain is achieved at the fully clockwise setting (+32 dB, 40 X), and this setting yields maximum mixer/system headroom. A setting of less than fully clockwise will yield lower system noise at the expense of mixer/system headroom. Turning the control fully counterclockwise is the “off” setting (-∞). It is always a good idea to power up any new installation at this setting to protect the system loudspeakers.

(2)POWER LEDS (PWR)

These indicators illuminate when the AC mains power is being supplied to the amp and both channels are operational. If either channel experiences fault conditions, exceeds safe operating temperature limits, or if the mains circuit breaker trips; both channel power LEDs will be dark, indicating “shutdown”. If the BRIDGE mode is selected, the PWR indicator on channel B will remain dark as a positive indication of this mode selection.

(3)SIGNAL ACTIVITY LEDS (SIG)

These indicators illuminate when the associated channel output signal level exceeds 1 V RMS.

(4)DDT™ ACTIVE LEDS

These indicators illuminate when DDT compression is taking place in the associated channel. With the DDT ENABLE / DEFEAT switch on the back panel in the ENABLE position, these LEDs indicate clipping is occurring in the corresponding channel. The Peavey DDT compression system will be covered in greater detail later in this manual.

(5)POWER SWITCH

This heavy-duty, rocker-type switch turns on the mains power to the amplifier. When the mains power is applied, there is a three-second delay in activation of the unit. This reduces/eliminates the turn-on transients associated with the system equipment connected to the amplifier and protects loudspeakers.

(6)CIRCUIT BREAKER

There is one circuit BREAKER on the PV® amplifier. This breaker is provided to limit current to the associated power transformer, and protect it from overheating and possible destruction due to fault conditions in the unit. The trip current values have been carefully chosen to allow reasonable continuous power output performance, while still protecting the power transformer. This breaker should not trip unless there is a fault in the amplifier circuitry that causes excessive mains current draw. 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 per channel or 4-Ohm bridge load) can cause the breaker to trip. If this occurs, turn the POWER switch OFF and reset the breaker, after waiting a brief period of time to allow the unit to cool down. Efforts should be made to correct the cause of the overload if possible. When tripped, the button on the BREAKER will be outward approximately 1/4" and can be reset by pushing inward and upward. A normal reset button is relatively flat. If the breaker trips instantly each time you attempt to turn the unit on, it should be taken to a qualified Peavey Service Center for repair.
