7. RECORD OUT JACKS
These phono connectors carry the pre-EQ (not
affected by the MAIN EQ) main mix signals.
RECORD OUT signal levels are regulated by
the MAIN master. Using phono-to-phono
patch cords, connect the RECORD OUT jacks
to the Aux. (line-level) inputs on the tape deck.
Actual recording levels would now be adjust-
ed using the tape deck's record level control/s.
For optimal recording, you may have to set
the MAIN master and channel levels fairly high. So, if you need to record while the
MP8D
is
operating in a PA situation (and set at lower levels, perhaps in a church) you can have a techni-
cian make up a couple of short padded patch cables as described below.** This cable would be
connected between the MAIN LINE OUT jack and the AMP IN jack(s). The amount of signal
going to the power amplifier(s) will be reduced so that the MAIN master and channel levels can
be set high enough to provide adequate RECORD OUT signal levels (without the PA system
being too loud.) Normally, the
MP8D
uses both Amp A and Amp B for the mains. If so, you have
to pad both amplifiers. The best way to achieve this is to use a “Y” adapter. See diagram below.
** To fashion the -20dB padded patch cables, start with two short, shielded patch cords. On each
cord, solder a 10k Ohm resistor in series with the tip of the plug to be inserted in a LINE OUT
jack, then solder a 2.2k Ohm resistor across the plug to be inserted in an AMP IN jack. It would
then be advisable to identify either the LINE OUT or AMP IN plugs on both cords perhaps with
tape or a dab of paint on the plug jacket.

This jack may be used to connect a standard on/off footswitch for the internal DIGITAL
EFFECTS PROCESSOR or alternately, as an effects send jack. In this latter function, it would
send the signal so that you could connect an external effects unit. If it is stereo, you would
connect the unit's left and right outputs to the dual RCA inputs on channel 7 or 8 (please note
that the channel inputs are not in stereo and that the stereo effect would be summed into a
mono mix). Here you would need to keep the GAIN level of that channel fairly low and make
sure that its EFX control is turned off. If the effects unit uses 1/4" plugs, you could connect the
output of the unit to any one of the BALANCED LINE IN jacks. As another alternative, the EFX
FOOTSWITCH/SEND jack may be used to deliver line-level signal to the input of an auxiliary
amp/speaker system, or a tape deck. Here, the channel EFX controls would act as secondary
level controls. Also keep in mind the channel EFX send controls are post-GAIN, so changes in
the GAIN settings will affect these levels as well.
