Rane MP 44 (2001 version) - Manual (Page 3)

Manual-2
INPUT CHANNELS
INPUTS 1A, 2A, 3A, and 4A are stereo,
unbalanced RCA jacks that operate as RIAA
equalized Phono Inputs or Line Inputs.
PHONO switches set the mode for Inputs
1A, 2A, 3A, and 4A. In the out position, these
Inputs operate at line-level (max input +20 dBu).
Press the switch in for PHONO operation. If a
turntable is not connected to one of these Inputs,
set the switch for Line (out).
PHONO GROUND posts are provided for connecting turntable ground wires. It is very important that each turntable have
a secure ground connection to the MP 44.
INPUTS 1B, 2B, 3B, and 4B enter via stereo, line-level, unbalanced RCA jacks. Maximum input level is +20 dBu.
SOURCE switches select A (Phono/Line) or B (Line) for
each Input Channel.
Input LEVEL controls adjust the gain from –12 dB to +12
dB. The center detent position provides 0 dB of gain (unity).
Use this control in conjunction with the OL (overload indica-
tor) to set the input gain for the best signal to noise perfor-
mance.
OL (overload) indicators light when the maximum
undistorted signal level has been reached. These are fast
responding peak detectors that light 3 dB before clipping.
Adjust Input LEVEL controls so that these indicators remain
off. This ensures that your sound remains clean and
undistorted and that adequate head room is reserved for
mixing. The OL indicators are not beat matching indicators.
EQ switches engage the 3-band tone controls. EQ switches
may be used in conjunction with the Hi, Mid and Low rotary
tone controls as “kill” switches. Set the rotary controls and flip
the switch.
HI tone controls affect frequencies from 4 kHz to 20 kHz. The range of control is +6 dB to OFF (full kill). The center
detent position is unity gain. These controls are positioned just above the vocal range and may be used for small tonal changes
or for the elimination of high frequency signals.
MID tone controls affect frequencies from 300 Hz to 4 kHz. The range of control is +6 dB to OFF (full kill). The center
detent position is unity gain. These controls may be used for small tonal changes or for the elimination of midrange signals.
LOW tone controls affect frequencies from 20 Hz to 300 Hz. The range of control is +6 dB to OFF (full kill). The center
detent position is unity gain. These controls influence signals below midrange vocals and may be used for small tonal changes
or for the elimination of bass and beats.
A – POST – B switches independently assign CH 1, CH 2, CH 3 or CH 4 to the A side of the crossfader, B side of the
crossfader or POST (after) the crossfader. The ability to assign an Input Channel to the desired mix eliminates the need for
redundant source selection on each of the four input channels.
Input Channel Faders control the mix level for each of the 4 input channels. These are VCA control faders for extended
service life and reduced travel noise. Too achieve the best mix consistency, use input LEVEL controls to set the gain and
Channel Faders to control the mix.
