Mixer Layout
18. Effects SEND Knob – The SEND knob is used to adjust the total amount of effects
added to the master bus.
19. Effects Program (PROG) Selector – This control knob is used to select one of 16, 24–
bit DSP effects programs.
20. MASTER Knob – The MASTER volume knob controls the overall output level. This
knob determines the final output signal level. Signals from all channels are routed
here just before being routed to the built–in power amplifiers and Left and Right
speaker output jacks.
21. Metering LED Indicators – This six–segment bar meter shows the XP800's output
level. For optimum signal–to–noise ratio, set the VOLUME control so that program
material is usually at or around +3 to +6 VU, with occasional, but not steady light-
ing of the red "LIMITER" segment.
22. SPEECH/MUSIC Switch – The SPEECH/MUSIC switch is used to change the overall
frequency response, or tone contour, for the XP800 sound system. If your appli-
cation is mainly for music, press the switch down to select the MUSIC response
curve. If your application is mainly for spoken word, leave the switch up to select
the SPEECH response curve.
23. PHANTOM Switch – The XP800 features an onboard phantom power supply to oper-
ate condenser microphones. When the switch is engaged, the LED will illuminate
indicating that phantom power is now available on the microphone pre–amps.
IMPORTANT NOTE: To avoid a loud pop, be sure to turn down the MASTER level
control before plugging and unplugging the mic cables when the phantom power is
active.
