[. . . ] CPMTM 2462 Operations Manual Operating Guide For more information on other great Crest products, go to your local Crest dealer or online at www. crestaudio. com. Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock -- DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] After proper power has been supplied to the CPM 2642 the next step is to connect any outboard equipment such as recording devices, effects units, equalizers, and power amps. This section describes the optimum method for connecting your outboard devices to your mixer. All connections should be made with the power turned off on all associated units including the CPM 2642. Always use high quality cables and connectors to ensure optimum performance and minimal noise. 7 4. 3 MASTER L/R OUTPUTS Each of the Master L/R channels has an 0 dBu/2 k Ohm, 1/4" unbalanced output and a +4 dBu/ 600 Ohm, XLR balanced output. The unbalanced and balanced outputs can be used simultaneously. MONO OUTPUT The Mono Output is a +4 dBu/600 Ohm, XLR balanced output. MONO OUT mixes the post-fader L and R signals. The output signal level is affected by the L-R master faders as well as its own MONO LEVEL CONTROL (6). MONO LEVEL CONTROL This control adjusts the level on the MONO OUTPUT (5). Unity gain is at the center detente position and +6 dB of gain in the full clockwise position maximum. 11 5. 5 6 6. 4 7. 10 MASTER L/R INSERT IN/OUT (See page 11) These two 1/4" stereo (TRS) jacks allow an external device to be inserted into each of the signal paths, pre-fader in the Master L/R channel. A switch in the jack normally connects the send to the return until a plug is inserted. CONTROL ROOM L/R OUTPUT These two 0 dBu/10 k Ohm, unbalanced 1/4" (TS) outputs provide the signal to drive the control room monitors. The level is controlled from the HEADPHONE/CR LEVEL CONTROL on the front panel. TWO TRACK INPUT A 0 dBu/10 k Ohm, unbalanced 1/4" (TS) stereo input, which allows the signal from an external tape machine to be monitored on the HP/CR OUTPUT. This input is duplicated with a pair of parallel RCA connectors. 8. 9 9 9. 8 10. MAIN OUT RCA These outputs duplicate the MASTER L/R main, unbalanced output with a pair of RCA connectors for convenient connection to a tape machine input. 11 8 12 11. 12. GROUP 1--6 OUTPUTS These six unbalanced 0 dBu/2 k Ohm, 1/4" (TS) outputs provide the signals from GROUP 1--6. AUX 1-2 OUTPUTS Each of the two AUX1-2 master-mix channels has a 0 dBu/2 k Ohm, 1/4" unbalanced output and a +4 dBu/600 Ohm, XLR balanced output, which can be used simultaneously. AUX 3--6 OUTPUTS These four unbalanced 0 dBu/2 k Ohm, 1/4" (TS) outputs provide the signals from AUX 3--6. 13. VI. INPUT CHANNELS The input channels of the CPM 2642 are the heart of its versatility. Various channel configurations have been included to eliminate the need for patch cables and adapters. This section will describe those different configurations and the numerous features of each. 12 CHANNEL 1 AND 2 SUPER MIC/LINE CHANNELS (BACK PANEL CONNECTIONS) 19 20 14. MICROPHONE INPUT This XLR balanced input is for a low impedance microphone or (through ­20 dB pad) for a high level, high impedance line source.
