3、troller Module8 C22 Controller Module8 L20 Limiter Module8 Congratulations on your purchase of a Renkus-Heinz loudspeaker controller module for your P2400 or P2700 dual-channel power amplifier. Your Renkus-Heinz amplifier and controller module have been designed to provide years of trouble- free, hi

4、gh performance operation. We hope you enjoy them. Your Renkus-Heinz controller module was completely tested and inspected before leaving our factory and should have arrived in perfect condition. Please carefully inspect the module and its shipping carton for any noticeable damage and immediately not

5、ify the shipping company if you see any noticeable damage. Only you (the consignee) may institute a claim with the carrier for any damage incurred during shipping. If you have a problem, be sure to save the carton and all packing materials for the carriers inspection. Important Renkus-Heinz controll

6、er modules contain no user-serviceable parts and all service should be referred to qualified service personnel. We recommend that any module be returned to the factory in its original packing carton if factory service is required. Introduction RadioFans.CN 收音机爱 好者资料库 3 C12 C22 L20 OPERATION MANUAL I

7、nstallation Procedure Installation The installation procedure is the same for all loudspeaker controller modules. 1. Remove the existing module from the rear of the amplifier by taking out the 4 mounting screws that hold the module in place and gently pulling the module out of the amplifier chassis.

8、 Caution: Before removing the existing module from the amplifier, make sure the amplifier is disconnected from the main AC line. 2. Remove (disconnect) the flat wire cable/connector that connects the existing module to the amplifier. 3. Connect the flat wire cable/connector to the new module you are

9、 installing. Then gently insert the new module into the amplifier and secure it into place with the 4 mounting screws you originally removed. Note: The C12 controller module has 2 flat wire cable connectors on the PC board. The one to use is the one having the most pins. It is designated J12 on the

10、PC board. Caution: C12 modules are configured for use with a particular loudspeaker and C22 modules are customized for use with particular loudspeakers by the proper setting of several control switches. Make sure the module is set up to operate with your loudspeaker(s) before connecting the loudspea

11、ker(s) and turning on the system. The C12 loudspeaker controller module shown above is a single input input, dual output module used in single channel (mono) systems having either active 2-way loudspeakers (or 3-way loudspeakers set up for bi-amp operation) or in systems having full-range (passive)

12、loudspeakers and subs (refer to the block diagrams show below.) It provides crossover circuitry, protection against overload damage, and frequency response smoothing. The C12 is customized to match its associated loudspeakers with a PK-xxx kit that provides the necessary settings for the crossover,

13、protection, and equalization circuitry. There is no need to adjust the C12 before installing it.

An internal selector switch determines whether this connector provides a full-range looping output or

Channel 2 & 1 Audio Input Connectors Female 3-pin XLR type input connector for Channel 2 & 1. Refer to Audio Input Connector under the C12 for additional details. 4. Ground Lift Switch.

19、 The Ground Lift switch is used to separate the signal ground circuit 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

20、an AC connection is provided between the signal ground and the amplifier ground circuit (the chassis). Note: When the processed controller outputs are used to drive additional amplifiers, it is imperative that the amplifiers level controls be set at the same or a higher level than the level of the a

21、mplifiers being driven. Otherwise, the protection feature is lost for the other amplifiers. 4. Selector Switches The C22 Loudspeaker Controller Module has several selector switches and a Stereo/Bridging Jumper plug that are accessible when the module is outside the amplifier. The location of these c

22、ontrols is shown in the outline drawing on the next page. 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 pa

23、rallels that channels input connector 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 the previous page for further information.) The Stereo/Bridging Jumper plug is u

24、sed to bridge the two output channels together 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. Input Connections Ground Lift Switc

Stereo - Parallel - Bridge Output Mode Selector The Output Mode Select

34、or 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 into the two amplifier inputs are amplified separately and delivered in phase to outputs 1 & 2. The output levels are cont

35、rolled separately by the front panel mounted attenuators. In the Parallel mode, input 2 is disabled and the two amplifier channels operate in parallel from a single input signal fed into the Channel 1 input. This eliminates the need to install a jumper cable to operate the amplifier channels in para

36、llel. The outputs are separate and in phase and both input attenuators are active to permit different level settings for each channel. In the Bridge mode, a single signal fed into the Channel 1 input, drives both output channels in tandem and the output is delivered to the Bridge Output connector. T

37、his mode allows the two amplifier outputs to be strapped together ( bridged) to produce a single output with double the power capabilites of a single channel. Input #2 is disabled. Both input attenuators are active and must be set to the same level. Note that in bridge mode both sides of the output

38、should be consid- ered hot and should not be grounded and that the Limit and HPF switches should be set in the same position. 9. Ground Lift Switch. The Ground Lift switch is used to separate the signal ground circuit from the amplifier ground circuit and thus, eliminate hum induced by ground loops.

39、 In the left position, the signal ground is electrically connected to the amplifier ground circuit (the chassis). In the center position, the input signal ground is electrically disconnected from the amplifier ground circuit (the chassis). In the right position, an AC only connection is provided bet
