14、2400 or P2700 dual-channel, professional, power amplifier. Your Renkus-Heinz amplifier has been designed to provide years of trouble-free, high performance operation. We hope you enjoy it. Your amplifier may include a C12 or C22 loudspeaker controller module or a L20 Limiter Module in place of the s

15、tandard dual channel input module (see pages 8 to 13 for details). The C12 and C22 controller modules are dedicated companions to a specific Renkus-Heinz loudspeaker. They provide protection circuitry, electronic crossover circuitry and response optimization for their associated loudspeakers. The L2

16、0 is a limiter module with user adjustable limit and HPF controls. It is not loudspeaker specific and allows the user to adjust the controls to suit his applica- tion. Caution: If your amplifier includes a C12 or C22, it is configured for use with a particular loudspeaker model and should not be use

17、d 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 perfect condition. Please carefully inspect your amplifier and its shipping carton for any noti

18、ceable 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 and all packing materials for the carriers inspection. It is also a good idea to save the

19、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 Renkus-Heinz amplifier contains no user-serviceable parts and all service should be referred

20、 to qualified service personnel. We recommend that it be returned to the factory in its original packing carton if factory service is required.

Channel 2 Status (Prot/Pwr) LED The Channel 2 Status LED glows green to indicate the amplifier is on and Channel 2 is operating normally. It glows red to indicate that one or more of the amplifiers

25、Channel 2 protective circuits has been activated. The amplifier contains separate over-temperature, DC on output and shorted- load protective circuitry for each channel. Whenever a fault is detected in Channel 2, the channel is temporarily shut down and the status light turned red to call attention

26、to the problem. The channel will remain off until normal operating conditions are restored. Note. The status LED is also controlled by the C12 setting the attenuators at a lower level maximizes the system signal/noise ratio. 7.

Before connecting the amplifier, check the AC voltage requirement and make certain the unit is connected to the

28、 proper voltage. Failure of the unit will result if a 120 volt amplifier is connected to a 220 volt power line. 2. Channel 2 Output Connector 4-Pin Neutrik Speakon connector provides single-connector, quick-disconnect facilities for Channel 2 on pins 1+ used to drive addi- tional amplifiers. 3. FR/H

29、F Output Connector Male 3-pin XLR type controller output connector for the FR/HF channel; used to drive additional amplifiers. Note: When the processed controller outputs are used to drive additional amplifiers, it is imperative that the source amplifiers level controls are set at the same or a high

30、er level. Other- wise, the protection feature is lost for the other amplifiers. The C22 loudspeaker controller module is a dual input, dual output controller designed for use in stereo systems having either passive loudspeakers or subwoofers. In these systems, it provides protection for the loudspea

31、kers or subs, as well as high provides a loop- ing controller processed output for use in driving additional amplifiers. 3.

The input is electronically balanced. We recommend the use of pin 2 as hot and pin 3 as neutral. Pin 1

34、is chassis ground. When the amplifier is connected to a balanced source, the shield may either be lifted or connected at the source end. The choice should be made on the basis of minimum hum. With an unbalanced source, connect the signal to pin 2 and source ground to pin 3 (connecting the signal to

35、pin 3 is not rcommended as this will cause a 180 phase inversion at the amplifier outputs). Note: Improper operation results when only pin 2 or only pin 3 and pin 1 (ground) are used for an unbalanced input. 4. Ground Lift Switch. The Ground Lift switch is used to separate the signal ground circuit

36、from the amplifier ground circuit and thus, eliminate hum induced by ground loops. In the right position, the input signal ground is electrically connected to the amplifier ground circuit (the chassis). In the left position, only an AC connection is provided between the signal ground and the amplifi

Channel 1 FR/HPF Output Connector Male 3-pin XLR type controller output connector for the FR/HPF channel; used to drive addi- tional amplifiers.

38、An internal selector switch determines whether this connector provides a full- range looping output or a processed band-limited high pass filter output.

41、NKUS-HEINZ MADE IN USA CH 1 OUTPUTS 1325674 PROCESSED 12 P2400/P2700 OPERATION MANUAL The C22 Loudspeaker Controller Module has several selector switches and a Stereo/Bridging Jumper plug that are accessible by removing the module from the amplifier. The location of these controls is shown in the ab

42、ove outline drawing. The Looping/HPF switches control the signals to the Looping/HPF output connectors. In the Filtered position, the associated output connector is connected to the output of that channels high pass filter. In the other position, the connector parallels that channels input connector

43、 and servers as a looping output. The HPF setting is used to deliver a band-limited signal to an additional amplifier for non-overlap operation (refer to the system wiring diagram on page 16 for further information). The Stereo/Bridging Jumper plug is used to bridge the two output channels together

44、to provide a single output with twice the power capabilities of a single channel. Note that the Jumper Plug is located under the right PK22-xxx kit, which must be removed (unplugged) to gain access to the Jumper Plug. The switches identified as sw 1, sw 2 and sw 3 are used to configure the C22 for s

45、pecific loudspeakers. Additional information on these switches can be found in the C22 Operation Manual. The L20 is a dual-channel limiter module. It is not loudspeaker specific and is provided with user adjustable limit and HPF (high pass filter) controls (refer to drawing on next page). It is used

46、 to provide limiting on both amplifier channels (loudspeaker protection) plus low frequency rolloff. 1 & 6. Looping Audio Output Connectors These male 3-pin XLR type connectors are wired in parallel with the input connectors and provide unprocessed looping Channels 1 and 2 outputs. They allow loopin

47、g through to additional amplifiers. 2 & 5. HPF Selector Switches Three position switches allow the Channel 1 and 2 low frequency rolloff points to be set at either 30 Hz, 60 Hz or 100 Hz to protect small loudspeakers from over excursion damage.

Stereo - Parallel - Bridge Output Mode Selector The Output Mode Selector allows the amplifer to be operated in 3 different output modes. In the Stereo mode, the two channels operate independently, just as they do in a stereo amplifier: signals fed
