25、oFans.CN 收音机爱 好者资料库 ENGLISH 4 PVSERIES PROFESSIONAL STEREO POWER AMPLIFIER INTRODUCTION Congratulations! You have just purchased the worlds finest professional power amplifier. The PV amplifier features a two-way crossover and sub-sonic (low-cut) filter for each channel. Crossover frequencies are fi

26、xed at 150 Hz, allowing subwoofers to be driven at extremely high sound pressure levels, and the filters cut at 40 Hz to prevent low-end rumble. Using proven technology gained through years of amplifier design, this unit takes advantage of rugged TO-3P output devices mounted on massive aluminum extr

27、usions and dissipates heat via an extremely quiet and effective two-speed fan. PV amplifiers employ mammoth toroidal power transformers and offer impressive specifications and features not found on similarly priced competitive units. This amp is designed to drive a 2-Ohm load per channel, thus achie

28、ving awesome performance levels into 4 Ohms in BRIDGE mode. PV amplifiers are ruggedly constructed, rack-mountable pieces of gear with superb patching capability, allowing superior flexibility in application. Front panel features include calibrated, detented gain (dB) controls and LED indicators for

29、 power (PWR), signal presence (SIG), and DDT (Distortion Detection Technique) activation on each channel, as well as a rocker mains POWER switch. The back panel contains an IEC connector for the mains power cord, a mains circuit breaker with reset, and the critical cooling fan opening. This opening

30、should have an adequate supply of cool air and should never be blocked or restricted. Also on the back panel are the input and output sections, including an input barrier strip for permanent installations. Each channel input section includes a combo XLR / 1/4 phone jack connector, THRU/LOW out and H

31、IGH out 1/4 jacks, and activation switches for the LOW CUT filter and crossover (150 Hz XOVER). Channel output sections feature dual shock-proof binding posts and four-conductor Speakonconnectors. An additional four-conductor Speakon connector allows BRIDGE mode output. UNPACKING Inspect the amplifi

32、er during unpacking. If any damage is found, notify your dealer immediately. Be sure to save the carton and all packing materials. Should you ever need to ship the unit back to Peavey Electronics, one of its service centers, or the dealer; use only the original factory packing. INSTALLATION PV profe

33、ssional power amplifiers are designed for durability in commercial installations and provide the quality performance required in studio and home applications. They are two-rack-space units of 16 (406 mm) depth designed to mount in a standard 19 rack. Rear mounting ears are provided for additional su

34、pport. The minimum rack depth required from the mounting surface is 17 (432 mm) to allow adequate connector clearance. BASIC SETUP Rack mount the amplifier in the location where it is to be used, remembering to allow for adequate access and cooling space. Make all the connections to the proper INPUT

35、 connectors on the desired channel. Select the proper mode configuration (STEREO or BRIDGE). Connect speakers to the proper OUTPUT connectors, reviewing carefully the impedance and phase considerations. With the POWER switch OFF, connect the IEC cord (7) to the amplifier and then to a suitable elect

36、rical outlet to allow proper current draw. With both channel gain (dB) controls at their fully counterclockwise (-) settings, turn the POWER switch to ON, and slowly raise the gain controls to desired settings. Please carefully review this manual. It covers all this information in greater detail. 5

37、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 se

38、tting 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

39、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; b

40、oth 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 excee

41、ds 1 V RMS. (4)DDTACTIVE 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 s

42、ystem 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 associ

43、ated with the system equipment connected to the amplifier and protects loudspeakers. (6)CIRCUIT BREAKER There is one circuit BREAKER on the PVamplifier. This breaker is provided to limit current to the associated power transformer, and protect it from overheating and possible destruction due to faul

44、t 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

45、. 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 wait

46、ing 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 th

47、e breaker trips instantly each time you attempt to turn the unit on, it should be taken to a qualified Peavey Service Center for repair. 12 3 4 4 3 21 5 6 BACK PANEL FEATURES (7) IEC MAINS CONNECTOR This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings f

48、or the intended operating voltage is included in the carton. U.S. DOMESTIC AC MAINS CORD The mains cord supplied with the unit is a heavy-duty, three-conductor type with a conventional 120 VAC plug with ground pin. It should be connected to an independent circuit capable of continuously supporting a

49、t least 15 amps. This is particularly critical for sustained high-power applications. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire grounded properly. Never break off the ground pin on any equipment. It is provided for your safety. The use of extension cords should be avoided but, if necessary, always use a three-wire type with at least a #14 AWG wire size. The use of lighter wire will severely limit the power capability of this amplifier. Always use a qualified electrician to install any new electrical equipment. To
