Manual-5
The LIMIT threshold control sets the maximum allowable MASTER signal level. The Limiter affects both
House and Booth signals. This control is located on the rear panel and screw driver adjust to prevent tampering.
Threshold range is –20 dBu to +20 dBu. Center detent is 0 dBu. LIMIT threshold indicators are located on the front
and rear panels.
Only 6 dB of post limiter makeup gain is available. To set the maximum system level, adjust the Limiter with
HOUSE and BOOTH LEVEL controls set to maximum. Applications include limiting SPL, protecting amplifiers
and speakers.
A note to DJs: If you are running gains high enough to cause hard limiting, faders and tone controls will not respond as
expected. For example, if you run signal levels 10 dB over the Limit threshold, you must turn signal levels down 10 dB before
you hear a reduction in level. The Limiter is a safety net designed to protect ears and equipment. Under normal operating
conditions, the LIMIT indicator should only flash occasionally.
MASTER HOUSE & BOOTH OUTPUTS
The PEAK PROGRAM METER has two modes of operation. In LEFT / RIGHT mode (up)
the meter indicates House Output level. In CUE / PGM mode (down), the top half of the meter
shows the mono CUE level and the bottom half mono MASTER level. Set for CUE / PGM, you
can see the relative beat and level of the Master mix and Cue signals.
The PEAK PROGRAM METER has two sensitivity settings. Push the recessed METER
SENSITIVITY switch in so that 0 dB = +4 dBu (less sensitive). Set the switch to the out position
so that 0 dB = -10 dBV (more sensitive). The meter is peak responding with a 1 second peak hold.
MASTER HOUSE LEVEL & BOOTH LEVEL faders are VCA controlled for extended
service life and reduced travel noise.
The MASTER BALANCE control determines the left/right balance of the MASTER mix. The
control influences both HOUSE and BOOTH Outputs.
The MASTER MONO switch is a recessed front panel switch used to set HOUSE and
BOOTH Outputs for mono operation. The Green MONO indicator lights when the MONO switch
is engaged.
HOUSE OUTPUT jacks give you two choices. The XLR Outputs have a maximum
signal level of +20 dBu, and are the preferred connection to equalizers, crossovers or power
amplifiers. The unbalanced RCA outputs have a maximum signal level of +16 dBu. Do not
drive unbalanced cables longer than 10 feet (3 meters); 6 feet (2 meters) or shorter is
recommended. Both types may be used simultaneously
BOOTH outputs are balanced ¼" TRS Outputs with a maximum signal level of +20 dBu.
HEADPHONE MONITOR
MONITOR controls determine the source and level of the PHONES signal.
With the MONITOR MONO switch out, the PAN control fades between stereo
CUE and stereo PGM signals. The CUE signal is selected using CUE CH 1, CH 2,
CH 3 and CH 4 switches in any combination. The associated yellow indicator lights
when a CUE is active. The PGM signal monitors the HOUSE Output (same signal
going to the Master House).
With MONITOR MONO selected (in), the PAN control fades between mono
CUE (left ear) and mono PGM (right ear).
