Rane MP 44 (2001 version) - Manual (Page 6)

Manual-5
The MASTER 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 PROG / CUE mode (down), the top half of the
meter shows the mono Master level and the bottom half mono Cue level. Set for PROG / CUE,
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 are balanced XLR
Outputs with a maximum signal level of +20 dBu.
UN-BAL HOUSE OUTPUT jacks are unbalanced RCA outputs with 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.
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 and mono PGM.
