[. . . ] C1648P 2000w Powered mixer C1648P REAR PANEL 1 C1648P REAR PANEL FEATURES: 1. SPEAKER OUTPUTS The combination SPEAKON jacks also accept 1/4" plugs. Chaining together more than one speaker on an output is fine as long as the total impedance is not below 4 ohms. If the speaker load is lower than 4 ohms, the amp may go into one of the PROTECT modes. [. . . ] The PAN control directs the channel into the L/R output or any of the 4 sub groups after depressing the appropriate ASSIgN switches. The PfL (pre fader listen) switch allows you to hear the channel in the headphones before the fader is turned up.

With the mixer unplugged and the unit turned off, complete the following procedures: · For high level balanced or unbalanced devices such as instruments & keyboards, plug into the LINE input jacks using a shielded cable with 1/4" phone plugs. CONNECTING AC POWER TO YOUR MIXER · The mixer can be used with 120 or 240VAC (it automatically switches internally) · Use only a grounded (3 prong) power outlet to prevent a shock hazard. CONNECTING INPUTS TO YOUR MIXER · For low level balanced devices such as microphones, plug into the balanced MIC inputs using a shielded microphone cable with XLR connectors. 3. TURNING YOUR MIXER ON · Adjust all channel FADERS and master LEVEL controls to their OFF positions · Adjust all channel's HI, MID, and BASS controls and the two master 9 Band GRAPHICS to their center positions. · Adjust the Channel "PAN" controls to their center positions. · Turn the mixer on by the rear panel POWER SWITCH and watch for the POWER LED. miC PhANTom PowER SwiTCh / REd LEd This switch provides +48v power for condenser mics such as Carvin's CM90E in groups of 8 channels. This leaves the remaining MIC inputs for sources that don't require phantom power. dUAL STEREo 24-biT EFFECTS PRoCESSoR The internal 24-BIT stereo processors receive signals from the channel EFF1 and EFF2 controls and the master EFF1 and EFF2 controls. If the adjacent PK (peak) LED flashes, reduce the level from the channel or master EFF1 or EFF2 send controls. A "solid" PK LED will show EFFEctS 1 or 2 have been muted by the MutE switches. The RETURN control will adjust the volume level of the selected effects. Remember each channel has its own two EFFECT sends that will send the signal to the effects processors. The red PK LED will indicate when the effects signal from the channel is distorting. Reduce the level of the channel EFFECT control until the PK LED stops flashing. EFFECT AND PARAMETERS a. )ECHO: When the SELECT control is at the "seven O-clock" position, it is selected to the first ECHO setting where you get a single repeat echo (minimal regeneration). Turning the PARAMETER control to 1 will provide the shortest delay time between the original signal and the echo. Increasing the PARAMETER control to the right will increase the time delay between the original signal and the echo. To increase the number of echo repeats, turn the SELECT control clockwise to "9 O-clock" (maximum regeneration). [. . . ] ComP 1-4 GRoUP ComPRESSoRS / LEds Each of the 4 sub groups features a compressor, which will reduce the output when it gets above the level you set with the COMP control. The compressor circuit is pre-fader, so you can set the COMP once and 44 still adjust the group fader as needed. The LED will indicate when the compressor is working. 45 42 43 36 35 34 34. dUAL PRECiSioN 9 bANd GRAPhiC EQs are one octave filters at 60, 125, 250, 500, 1k, 2k, 4k, 8k & 16k Hz centers that offer ±12dB adjustment to help eliminate feedback & enhance tone for the main or monitor mix.
