User manual RENKUS-HEINZ C12

[. . . ] Connect the flat wire cable/connector to the new module you are 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. [. . . ] C22 controller modules are customized to match an associated family of loudspeakers (for example, the TRC series) and must be programed to match a specific loudspeaker by the proper setting of several control switches. 4 C12 · C22 · L20 OPERATION MANUAL C22 Controller Module (continued) 1 2 3 4 5 6 7 MODEL C22 CH 2 OUTPUTS CH 2 INPUT PIN 1 = GND PIN 2 = + PIN 3 = - CH 1 INPUT CH 1 OUTPUTS RENKUS-HEINZ MADE IN USA PROCESSED LOOPING / HPF GROUND LOOPING / HPF PROCESSED 1 & 7. Channel 2 & 1 "Processed Output" Connector Male 3-pin XLR type controller "processed output" connectors for Channels 2 & 1; provide "looping" controller processed outputs for use in driving additional amplifiers. Channel 2 & 1 "FR/HPF Output" Connector Male 3-pin XLR type controller output connectors for the FR/HPF channels; used to drive additional amplifiers. An internal selector switch determines whether this connector provides a full-range "looping" output or a processed band-limited "high pass filter" output. Channel 2 & 1 Audio Input Connectors Female 3-pin XLR type input connector for Channel 2 & 1. 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 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 amplifier's level controls be set at the same or a higher level than the level of the amplifiers being driven. 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 controls 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 channel's high pass filter.
