[. . . ] This will minimize the amount of monitor signal that is picked up by the microphones. PHANTOM POWER Switch Push in this switch to provide phantom power to the XLR MIC input connectors. Phantom power is required to operate most condenser microphones (some condenser microphones are batterypowered). The PPM Series provide +15V DC phantom powering on pins 2 and 3 of the XLR connectors. If you are using condenser microphones, or any mic that requires phantom power, engage the PHANTOM POWER switch (located just below the EMAC section). If you have dynamic, ribbon, or tube mics that do not require phantom power, leave the PHANTOM POWER switch out. Phantom power will MASTER OUTPUT SECTION LEVEL CLIP 5 O O EFX TO MAIN Use this control to add the EMAC internal effects (or external effects, if connected) to the main mix. The effects signal is added to the main POWER signal path just after the RUMBLE REDUCTION switch 63 and just prior to the MAIN +15 MASTER control. 10 The EFX TO MAIN control 5 ranges from off through unity 0 (the center detent position) on 5 up to +10 dB of extra gain. 10 125 250 500 1K 2K 4K 8K 16K 15+ 10 5 0 5 10 15O O U +10 EFX TO MON U 0 5 10 15 20 MAIN MASTER This controls the overall signal level at the MIXER LINE and at the input to OUT(s) the power amplifiers.

Caution: Turn all output levels down before operating this switch to avoid the possibility of a "pop" in your speakers. Connecting a line-level input to an XLR input connector with the phantom power switched on could damage the output of the source device. We recommend using the 1/4" jacks for line-level inputs. PHANTOM POWER CH 1-8 BREAK (MUTES CH 1-6) When the switch is in the OUT position, the main mix is routed to the inputs of both amplifiers. For the mono versions (406M, 408M, 808M), the same signal is routed to the inputs of both amplifiers. When the switch is pushed IN, the main mix is routed to the input of the MAIN power amp, and the monitor mix is routed to the input of the MONITOR power amp. You can still connect up to two speakers to each amplifier output, since there are two parallel SPEAKER OUTPUT jacks for each amplifier on the back panel. Note: On the stereo versions (408S, 808S), the left and right signals are summed together just prior to the MAIN power amp input when the POWER AMP ROUTING switch is pushed in. BREAK Switch As in "take a break. " Push this switch in during your breaks and the mono channels (1-6), monitor send, and effects send are muted so you don't run the danger of something going haywire during your break, like having your system start feeding back or having some would-be poet jump up on stage and start reciting his latest epic. This switch doesn't affect the TAPE IN or the stereo channels (7&8) so you can go ahead and run your cassette or CD player while you are on break. COMPRESSOR Pushing this switch in activates a circuit at the input to the power amplifiers that senses the signal level and reduces the possibility of driving the amplifier into clipping. Clipping creates distortion that not only sounds bad, but can actually damage your loudspeakers. We recommend that you leave this switch pushed in (unless you hate your speakers). TAPE IN LEVEL You can connect a tape deck or CD player to the PPM Series and play back prerecorded music during your breaks. The tape signal is added to the main signal path just after the RUMBLE REDUCTION switch and just prior to the MAIN MASTER control. This is a stereo control, but for the mono versions (406M, 408M, 808M), the left and right inputs are summed. POWER AMP ROUTING This handy switch provides the flexibility to use the internal power amplifiers to power both the main and monitor outputs, or to power two main speakers with the internal amplifiers and use a separate power amplifier to power the monitor speakers.

[. . . ] Doing so helps minimize hum, buzz, and other extraneous non-audio signals. Many "authorities" tell you that shields should be connected only at one end. Sometimes this can be true, but for most (99%) audio systems, it is unnecessary. If you do everything else correctly, you should be able to connect every component of your audio system using standard, off-the-shelf connecting cables that are available at any music store. Here are some guidelines: 1. [. . . ]
