DSP EFFECTS PROCESSOR A 24-Bit processor provides a host of great sounding effects including Flange, Reverb, Echo, & Chorus. The channel EFF send control delivers the signals to the processors.Note: Reduce these levels if the red PEAK LEDs are flashing on the processors. Turn up the MAIN effects control to add your effects to the MAIN outputs. Adjust the SELECT and the PARAMETER controls to get the desired effect. Note: An audible noise will be heard while adjusting the effects. A) ECHO: SELECT the amount of the regeneration (repeating). Now select the PARAMETER control for the shortest or longest delay time between the original signal and the echo. B) REVERB: SELECT the amount of presence (high frequencies) in the reverb. Now turn the PARAMETER control to provide the minimum or maximum decay. C) CHORUS: SELECT the amount of reverb with your chorus. Now turn the PARAMETER control to increase the depth. D) FLANGE: SELECT the amount of speed with your flange (phasing effect). Now turn the PARAMETER control to increase the depth. 24 25 26 27 20 19 22 21 23 28 29 30 20. EFFECTS PEAK LED's The PK LED indicates that the signal level to the processor is too high. To prevent distortion, turn the EFF control towards the "0" (off) position until the PK LED stops flashing. 21. MAIN EFFECTS CONTROL The MAIN EFFECTS level controls the amount of the effects that go to your MAIN outputs. 22. MONITOR EFFECTS LEVEL The MONITOR EFFECTS level controls the amount of the effects that go to your MONITORS. 23. MUSIC BREAK SWITCH / LED The MUSIC BREAK feature turns off all inputs, except for channel 6. This is useful during breaks. This allows pre-recorded music to be played through the TAPE IN jacks. The channel 6 MIC/LINE inputs are left active for announcements or solo acts. The remaining input channels (1-5) are turned OFF eliminating feedback or other unwanted sounds from open mics during breaks or changes. The LED indicates the MUSIC BREAK is ON. The internal effects are also muted. 24. GRAPHIC EQ MAIN + MONITOR When the EQ sliders are in their center position, they do not affect the audio signal. When EQ sliders are raised or lowered from this position, they boost or cut a narrow frequency band. For tone enhancement you may want to raise the 80Hz and 160Hz sliders (for deeper bass) and the 6kHz and 12kHz sliders (for crisper highs) while reducing the 400Hz, 800Hz and 2kHz sliders in a moderate "curve". To help prevent feedback, microphones should be placed behind the main speakers. To reduce feedback in the low frequency range, try lowering one of the 80Hz or 160Hz sliders. High frequency feedback is usually reduced by lowering the 2kHz or 6kHz sliders. 25. OUTPUT LED's /AMP "CLIP" LED's The OUTPUT METER LEDs indicate the output levels for each power amp. The yellow "+6" LED indicates the output level is near maximum. The red CLIP LEDs indicate when the power amps are starting to distort (clip). Reduce the MAIN and/or MONITOR master levels to prevent distortion. 26. POWER LED The blue POWER LED indicates the mixer is powered ON. 27. PROTECT LED The mixer will "protect", engaging relays to mute the speakers if: a) impedance is below minimum on any amplifier b) shorted speaker cables, or c) ventalation problems. If the LED comes on, shut the mixer OFF and check for cable problems, proper impedance and obstructed rear cooling vents. If you encounter an over-heat problem, leave the mixer ON allowing the fan to cool down the internal components. The mixer will auto-reset in about 5 minutes. 28. 48V PHANTOM POWER SW/LED The 48V PHANTOM POWER switch turns on the microphone phantom power in the channel XLR jacks. This power is used for supplying a high voltage to condenser microphones. The LED indicates the phantom power is turned on. The phantom power will not damage conventional dynamic microphones. Note: Make sure the phantom power is switched off before connecting or disconnecting microphones to avoid a "pop". 29. AMP ASSIGN SWITCH This switch allows you to use one amp for MAIN and one amp for MONITOR, or use both power amps for the MAIN speakers. The front MONITOR output jack remains unchanged and can still be used for external power amps or in-ear monitor systems. 30. EFFECTS FOOT SWITCH JACK The optional FS22 will remotely shut off the internal effects. REAR PANEL-POWER/SPEAKER CONNECTIONS The rear panel contains the POWER SWITCH and AC power cable connection. There are 2 groups of speaker jacks. Each group has one Speakon™ connector and two 1/4" outputs (wired in parallel). Each amp has a 2Ω MINIMUM IMPEDANCE (Maximum two 4Ω speakers or four 8Ω speakers per amp). MAKE ALL SPEAKER CONNECTIONS BEFORE TURNING THE MIXER ON .
