Flexfx, Active crossfader, Fader cleaning – Rane MP 44 (2003 version) User Manual
Page 5: Manual

Manual-
FlexFX™
FlexFX™
switches independently assign any combination of the four Input Channels to the FlexFX Loop for external
processing. FlexFX assignment is totally independent of A – POST – B mix assignment. You’ll get more out of your favorite
external effects box than you ever thought possible, and experiment with this feature for a long time to come. The indicator
illuminates when FlexFX is active on it's Channel.
FlexFX SEND
jacks are unbalanced ¼" Tip/Sleeve Outputs. The maximum output level is reduced to +16
dBu to accommodate the inputs on lower voltage external effects processors. All Input Channels assigned to the
FlexFX
loop are removed from the direct mix, summed together by the FlexFX summer and output on this stereo
pair of jacks.
FlexFX RETURN
jacks are unbalanced ¼" Tip/Sleeve Inputs. This stereo pair of jacks provide the return in-
put from the external processor's output. This Input provides 6 dB of gain to accommodate lower voltage external
processors. The maximum input level is +16 dBu. The FlexFX return signal is summed with the direct signals to
form the Left / Right mix.
ACTIVE CROSSFADER™
The MP 44 features a high-performance Active Crossfader. In
addition to low travel noise and long fader life, the design provides
the accuracy and consistency required by the most demanding Turn-
tablist. The continuously adjustable CROSSFADER CONTOUR
control provides smooth and consistent crossfader response adjust-
ment. Control ranges from the “constant power” response required
for smooth blends to fast cut. This crossfader design accommodates
all mixing styles.
The CROSSFADER CD TRIGGER switch enables the CD TRIGGER outputs which are ⅛" mini
TRS jacks. CD stop pulses are output on the Sleeve. CD start pulses are output on the Tip. The ring is
unused. Ground return is via the CD player RCA signal cables. The automatic CD trigger circuit monitors
the position of the Crossfader. When the Crossfader moves to full cut (0) for the A side, CD TRIGGER
1
outputs a 50 ms, active low stop pulse. When the crossfader moves just above full cut for the A side mix,
CD TRIGGER 1
outputs a 50 ms, active low start pulse. The same operation is true for the B side of the
crossfader and CD TRIGGER 2.

Fader Cleaning
With heavy use in harsh environments, the faders may need
lubrication. This treatment extends longevity and can make used
faders as good as new. The fader assembly must be removed from
the MP 44 for proper cleaning. We recommend any of the fol-
lowing cleaning solutions:
Caig DeoxIT FaderLube F100 spray lubricant (www.caig.com)
Caig DeoxIT FaderLube F5 spray cleaner (www.caig.com)
CRC 2-26 (www.crcindustries.com)
