Your Renkus-Heinz amplifier has been designed to provide yea

14、rs of trouble-free, high performance operation. We hope you enjoy it. If you purchased the model P3500, your amplifier will include either a PK-xxx-A loudspeaker controller module or a PK-BLANK-A blank card (see pages 8 to 13 for details). The PK-xxx-A is a dual channel controller module that is a d

15、edicated companion to a specific Renkus-Heinz loudspeaker. It provides protection circuitry, electronic crossover circuitry and response optimization for its associated loudspeakers. The PK-BLANK-A blank card is used when a controller module is not included. Caution: If your amplifier includes a PK-

16、xxx-A, it is configured for use with a particular loudspeaker model and should not be used with any other model. Use of the wrong loudspeaker may result in loudspeaker damage. Your Renkus-Heinz amplifier was completely tested and inspected before leaving our factory and should have arrived in perfec

17、t condition. Please carefully inspect your amplifier and its shipping carton for any noticeable damage, and if any damage is found, immediately notify the shipping company. Only the consignee may institute a claim with the carrier for any damage incurred during shipping. Be sure to save the carton a

18、nd all packing materials for the carriers inspection. It is also a good idea to save the carton and packing material even though the ampli- fier arrived in good condition. If shipping the amplifer should ever be required, it should be shipped only in its original factory packing. Important: Your Ren

19、kus-Heinz amplifier contains no user-serviceable parts and all service should be referred to qualified service personnel. We recommend that it be returned to the factory in its original packing carton if factory service is required. Introduction 5 P3500/P3501 OPERATION MANUAL Technical Specification

Plug

22、-In Module/Protection LEDs (on P3500 only) If your amplifier is a model P3500, it will include either a PK-xxx-A loudspeaker controller module or a PK-BLANK-A blank card. If the module is a PK-xxx-A, the model number of the associated loudspeaker will be included on the face of the module as shown i

23、n the above drawing. PK-BLANK-A cards carry no loudspeaker model number. Both the PK-xxx-A and PK- BLANK-A have two LEDs (one for each amplifier channel) as shown above. These LEDs light up (turn red) whenever the loudspeaker protective circuits are activated. The P3501 amplifier has no provisions f

24、or plug-in loudspeaker controller modules and does not have these two LEDs. Note: The following instructions apply to both the P3500 and P3501. 2. Signal LEDs The two Signal LEDs (one for each amplifier channel) glow green to indicate the presense of an audio signal in the amplifier and red to indic

25、ate clipping. Occasional operation of the red clip indication (flickering of the red light) is an indication of optimum system utilization. Extended illumination of the red clip light is a sign the system is being overdriven and should be avoided. 3. Output LEDs The two Output LEDs (one for each amp

26、lifier channel) indicate the status of the amplifiers protective circuits by glowing red whenever one or more of the amplifier protective circuits has been activated. The amplifier contains separate over-temperature, DC on output and shorted- load protective circuitry for each channel. Whenever a fa

27、ult is detected, the offending channel is shut down and the status light turned red to call attention to the problem. The over- temperature and shorted output protective circuits are self restoring and the channel will return to normal operation as soon as the problem is corrected. The circuit that

28、protects against DC on the output is not self restoring and the channel will remain off until the circuit is reset by turning the amplifier off and then on. Note: If the status LEDs remain red after the circuit is reset, the amplifer needs to be looked at Output LEDs 13 -CH1 -CH2 PROTECTION SR7/9 -

Important - - When the amplifier is being operated in

30、the bridging output mode, both attenuators must be set in the same position to avoid a mismatch in the signal level being sent to each channel. 6. Power On/Off Switch and Circuit Breaker This switch is used to turn power to the amplifier on and off. It also acts as a protective power line fuse (circ

31、uit breaker) and in case of overload will automatically turn the power off. If the switch shuts off during normal use, push it back to the on position just one time. If it will not stay on, the amplifier needs service. Do not attempt to operate the amplifier by holding the switch in the on position.

32、 Before connecting the amplifier, check the AC voltage requirement and make certain the unit is connected to the proper voltage. Failure of the unit will result if a 120 volt amplifier is connected to a 220 volt power line. Standby LED 8 P3500/P3501 OPERATION MANUAL Rear Panel Features AC Power Cord

33、 Output Connections 1. AC Power Cord A line cord with appropriate matching connector is supplied with the amplifier. Before connecting the amplifier, check the AC voltage requirement listed on the name plate and make certain the unit is connected to the proper voltage. Failure of the unit will resul

34、t if a 120 volt amplifier is connected to a 220 volt power line. 2. Blank Plate The blank plate covers space reserved for an optional computer control module. 3. Channel 2 Output Connectors The two binding posts marked 2- i.e., input connector #1 drives amplifier channel #1 and input connector #2 dr

35、ives amplifier channel #2. The outputs are separate and in phase. Both input attenuators are active to allow different level settings for each channel. Mono Mode In the Mono Mode (far right position), input # 2 is disabled and the two amplifier channels operate in parallel from a single input (input

36、 # 1). This eliminates the need to install a jumper cable to operate the amplifiers in parallel. The outputs are separate and in phase and both input attenuators are active to permit different level settings for each channel. Do not parallel the amplifier outputs! Bridge Mode This mode allows the tw

37、o amplifier outputs to be strapped or bridged to produce a single output with double the power capabilites of a single channel. Both channels are driven from a single input (input # 1), but out of phase. Input #2 is disabled. Both input attenuators are active and must be set to the same level. Note

38、that in bridging mode both sides of the output should be considered hot and should not be grounded. 897 CH2 OUTPUT -LINE LEVEL- INPUT CH2 MONO STEREO BRIDGE L O OP IN G /P R OC E S SE D L O OP IN G /P R OC E S SE D CH1 OUTPUT -LINE LEVEL- INPUT CH1 P1 G P2 + P3 - 10 P3500/P3501 OPERATION MANUAL If y

39、ou hav a model P3500 amplifier, it will include either a plug-in PK-xxx-A loudspeaker controller module (see above photograph) or a PK-BLANK-A blank card. If the module is a PK-xxx-A controller module, the model number of the associated loudspeaker will be labeled on the front of the module below th

40、e two loudspeaker protection LEDs. If the module is a PK- BLANK-A blank card, there will be no loudspeaker model number on the face of the module. PK-xxx-A controller modules are loudspeaker specific modules (the xxx is associated with the model number of the associated loudspeaker). The modules pro

41、vide protective circuitry for that specific loudspeaker model along with electronic crosssover, response smoothing and, where appropriate, low/mid frequency time alignment. The protective circuitry protects the transducers from overheating (thermal overload) and the damage caused by high level trans

42、ients. Protection against damage from over excursion, a problem associated with low frequency drivers is also provided. The operating parameters of PK-xxx-A controller modules are preset during manufacture to match a specific loudspeaker and are not user adjustable. Do not attempt to change or modif

43、y them in any way. PK-BLANK-A cards are used when a controller module is not needed. Note: If your amplifier is a P3501, it will not have facilities for a plug in module and will not include the two loudspeaker protection LEDs found on the P3500.

Both amplifiers are fan cooled and it is important that an ample supply of air is provided at the amplifier rear and a free air exhaust space is provided in front of the amplifier. The two internal fans provide adequate cooling when the rack has an open back and the front is not obstructed. Closed back racks may need to be pressurized and provided
