Other aspects to consider 23
24-Track Recorder
The RM800 does not allow simultaneous discrete recording onto 24 tracks, yet
there is a way to record up to 16 tracks in one pass and still route all tape'
returns to the 24-channel version of the RM800 for permanent playback and
mixdown control. That is not a flaw, by the way. Even the biggest mixing con­
soles in the world have more inputs than there are tape outs.
A workable 24-track setup requires an 8-ins/16-outs patch-bay connected to
the GROUP OUT connectors. The 16 patch-bay outs need to be connected to
16 inputs of the multitrack recorder(s), while the 8 ins of your patch-bay must
be connected to GROUP OUT 1-8. Again, you may want to connect output 1
of the patch bay with input 1 of your multitrack, ‘2’ with ‘2’, and so on. Connect
the outputs of your multitrack with the TAPE IN jacks 1-24 of your RM800.
Working this way means that you will not be able to record onto tracks 1 and
9,2 and 10... 9 and 16 simultaneously, but then again, the fact that you have
eight Groups and a flexible assign matrix (i.e. there is no need to assign input
module 2 to Group 2 - choose any assignment you need) means that you can
work efficiently. Just remember to patch the GROUP OUTs to the right multi­
track inputs.
Connect the TAPE SEND (GROUP OUT/DIRECT OUT) 17-24 connectors to
the remaining eight track inputs and feed the tape outs of the multitrack to the
TAPE IN connectors of these modules (17-24).
Other aspects to consider
Microphones
Microphones, especially those that require phantom powering must be con­
nected to MIC/LINE inputs 9-16 (or 17-24 on RM800-24). Set the PHAN­
TOM power switch (rear panel, below the POWER switch) to the ‘On
position.
Note: When the PHANTOM power switch is on, +48V is present at all 8 (9~16 or
17-24) MIC/LINE XLR connectors. Be careful not to damage other signal sources
that may he connected to the XLR connectors. For security reasons, we strongly sug­
gest you disconnect all signal sources that do not require phantom power before set­
ting the PHANTOM power switch to the ‘On’ position.
Microphone positioning is a crucial aspect for professional sounding record­
ings. As a rule, the angle and distance at which the microphone is positioned
with respect to the signal source determine the sound that will be recorded.
Before deciding to correct the frequency response of the signal source using the
EQ, try other positions and listen to the result. The type of microphone used
to pick-up a signal source is another important aspect. Try to read as much as
you can lay your hands on about microphone positioning and microphone
types. Also, ask your friends and colleagues for advice.
