User manual RENKUS-HEINZ P2801

[. . . ] Caution: C12 modules are configured for use with a particular loudspeaker and P2801 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 loudspeaker(s) and turning on the system.

FR/HF amplifer output to associated full-range loudspeakers or to the high frequency section of active 2-way loudspeakers. 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) loudspeakers and subs (refer to the block diagrams show below. ) It provides crossover circuitry, protection against overload damage, and frequency response smoothing.

Audio Input Connector Female 3-pin XLR type input connector. We recommend the use of pin 2 as "hot" and pin 3 as "neutral". 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 pin 3 is not rcommended as this will cause a 180 phase invervion 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. Output Connections 2 & 3. SUB/LF and FR/HF "Output" Connectors Male 3-pin XLR type controller output connectors for the SUB/LF and FR/HF channels; used to drive additional amplifiers. Note: When the C12's 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. Otherwise, the protection feature is lost for the other amplifiers.

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 used 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.

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 to provide limiting on both amplifier channels (loudspeaker protection) plus low frequency rolloff. "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 "looping" through to additional amplifiers. 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.

[. . . ] Limit Set Switches Three position switches allow the Channel 1 and 2 maximum output levels to be set at either 100, 200 or 350 watts into 8 ohms (400, 800 or 1400 watts in bridge mode). 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 into the two amplifier inputs are amplified separately and delivered in phase to outputs 1 & 2. The output levels are controlled separately by the front panel mounted attenuators. [. . . ]
