RQ® 880FX Powered Sound Reinforcement Mixing Console
General Description:
Congratulations on your purchase of the RQ® 880FX, the finest example of state-of-the-art mixing consoles. In
one compact package, we have included the feature set of eight low noise-discrete microphone preamps,
four stereo input channels, a stereo equalizer/automatic feedback finder, digital effects processor, and
Peavey's world-famous ruggedness and reliability. You can feel confident that the RQ 880FX mixing console
will meet your PA needs for many years to come.
To take advantage of the RQ 880FX's powerful features, please read this owner's manual carefully and keep it
as a reference. This owner's manual includes several sections detailing individual areas of mixer operation,
including: control functions, set-up, and applications in sound reinforcement.
The standard channels feature discrete low noise mic preamps with globally switched phantom power, low cut
filters, and three-band EQs with a semi-parametric mid control. There are four auxiliary sends (two dedicated
pre-EQ for monitor sends, two post-EQ/post-fader effect sends), mute, and PFL switches. The PFL logic auto¬
matically shifts the main Right meter to the PFL signal when any PFL button is pressed to assist in input gain
adjustment, and operates even when the channel is muted. The mute circuitry squelches the L and R bus and
effects sends.
"Super" mic channels 3 and 4 also have pad and phase reverse switches for those applications that require it,
as well as the standard channel functions. There are no line inputs on these channels.
In addition to the four mic channels, there are four combination mono mic/stereo line-level channels for tape,
CD, or synth inputs. Each of the four channels has all the standard channel functions including a separate dis¬
crete low noise mic preamp. The channels feature a separate control for the mic input and line-level stereo
inputs. Also, the stereo line inputs on these channels can be selected to go through the channel to the L/R
bus, or bypass the channel and feed directly to the L/R bus without EQ. This allows the mic and line inputs
to be used simultaneously yet controlled separately. The monitor sends on these channels are fed simultane¬
ously by stereo line inputs and mic inputs. The four stereo line input channels can also double as fully equal¬
ized stereo effects returns with PFL and mute, with sends to the main L/R mix and the Mon 1 and 2 mixes as
well as the Aux 1 and Digital Effects buses.
The master section features a unique graphic equalizer mode switch that allows the user to select between
stereo mode or main and monitor EQ mode. In stereo mode, the two graphic equalizers are used for the left
and right channels. In mono mode, one equalizer is used for main left/right mix and the other is used for mon¬
itor output.
We have incorporated 16 digital effects into a processor that is included in the master section as the on-board
digital signal processor. By including a separate time and damping/feedback control, the user can create
many effect settings from the 16 we provided. All channels have a dedicated digital effects send routed
directly to the DSP effects processor.
The balanced and unbalanced Left and Right equalized outputs each have LED meters. A balanced mono
output (derived from the post fader Left and Right outputs) has its own level control.
A lamp connector is provided for Peavey 18" ML-2 or 6" ML-3 flexible lamps to illuminate the console in dark
environments.
