Peavey is proud to introduce you to the new PV™ 500 amplifier. This amplifier uses proven technology gained from years of amplifier design, taking advantage of the rugged steel can TO-3 output devices for reliability. Unlike typical home stereo units, the PV 500 employs massive power transformers, very effective two-speed fan cooling, and offers impressive specifications and features not found on any other competitive unit in this price range. This amplifier was designed to drive 2 ohm loads per channel, thus delivering awesome performance levels at 4 ohm Bridge mode. The PV 500 offers rugged rack-mountable construction and more than adequate patching capability. The front panel contains a rocker mains switch, an LED power indicator, and dual LED DDT™ activation indicators. The back panel of each amplifier has an input level control, dual 1/4" phone jack inputs, 5-way binding post outputs, and dual 1/4" phone jack outputs for each channel. The resetable mains breaker is also located on the back. Additionally, the back contains switches for stereo/bridge select and DDT defeat. ? © © © FRONT PANEL FEATURES DDT™ ACTIVE LEDS (1) Illuminates when DDT compression is taking place in the channel. With the Enable/Defeat switch on the back panel in the Defeat position, this LED indicates when channel clipping is occurring. POWER LED (2) Illuminates when AC mains power is being supplied to the amp and both channels are operational. If either channel were to experience fault conditions, or have the associated circuit breaker trip, then the power LED will go out, indicating such conditions exist. POWER SWITCH (3) A heavy-duty, rocker-type switch. Selecting the “OFF” position turns off the power amplifier. BACK PANEL FEATURES CIRCUIT BREAKER (4) There are two circuit breakers located on the back of the PV 500. These breakers are provided to limit the current to the associated power transformer and protect it from overheating and possible destruction due to fault conditions in the amplifier. The trip current values have been carefully chosen to allow continuous power output performance while still protecting the power transformer. Normally, the 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 them to trip. If this occurs, turn the power switch off, then simply reset the breaker (s) and correct the cause of the overload. 3 A When tripped, the button on the breaker will be outward nearly 1/2" and can be reset by pushing inward. A normal reset button length is about 1/4". 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 breaker 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 SENSITIVITY (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 than full clockwise will yield lower system noise at the expense of mixer/system headroom. HIGH-Z INPUT JACKS (8) Two parallel (bridged) input jacks are provided for each channel. This allows for one to be used as a conventional input, and, simultaneously, the other to be used as a “line out” (Y-cord) to connect to another input jack...
