1606M Monitor Console
GENERAL DESCRIPTION:
The RQ
™
1606M compact mixer was designed to be used as a monitor console in sound rein-
forcement applications; it will complement any house console by expanding its monitor capabilities.
The mixer’s six monitor sends and left/right outputs make it possible to use it as a house mixer with
six equalized monitor sends—two can be used as effect sends by setting the pre/post switch to post.
CHANNELS:
This console has 16 input channels. All inputs feature discrete transistor, low-noise mic
preamps with a 20 dB pad switch to handle any input signal level (-57 dB to +30 dB). Channels 1-8
have insert jacks, channels 9-16 have high-impedance (10 k ohm) inputs. All have three-band
equalization with mid sweep, six monitor sends (four dedicated pre-fader, post EQ; two switchable
pre/ post fader), mute, and PFL. An overload detector monitors three different points in each channel
and lights when any point is within 2 dB of clipping, or when the mute switch is activated. The PFL
logic shifts the right meter to the PFL signal to assist in setting input gains to obtain the optimum 0
dBu internal levels.
A global phantom power switch with LED indicator applies power to all XLR inputs. Each input
is isolated from the others to provide protection for itself and for the front of house console, if 48 V is
already present. (Phantom power should be supplied by the FOH console if at all possible for best
performance and fewest problems.)
MASTER:
Each monitor output has a 100mm fader, mute, AFL, and a variable frequency low cut filter.
Insert jacks are available for patching in external equalization or a compressor/limiter if required. A
12-segment peak reading, meter monitors each output.
The left and right outputs can be used for an engineer’s mix, additional monitor mixes, record-
ing outputs, or even FOH feeds. These have their own meters and AFL switches.
Separate controls set the headphone levels and the wedge output levels. The wedge outputs
automatically diminish when the talkback mic is enabled to prevent local feedback. If the left-mono
jack is used without the right jack connected, it becomes a mono (mixed) signal.
The master PFL level is set by its own control; the AFL bus signal tracks the selected output
and does not have a separate adjustment. If no AFL or PFL switches are pressed, there will be no
signal at the headphones or at the wedge outputs. The talkback mic connector has phantom power
at all times, regardless of the phantom power switch setting (necessary if the house console is
supplying mic power and this mixer’s phantom switch is off). This mic signal is always sent to
monitors 1-6, and can also be routed to the left and right outputs. It is live only when the enable
button is held down.
All monitor and left/right sends have XLR balanced and 1/4" unbalanced outputs with
electronic turn-on and turn-off muting. A PFL link connection and auxiliary monitor bus inputs are
provided to allow expansion. The monitor bus inputs can also be used as line level inputs, however
any level adjustments must be made externally at the sources, as there are no input level controls.
