• In this example, you will be able to send the tape playback
signals to the stereo bus so that you adjust PAN (5) and
EQ (7), as well as add additional signal processing with
external units.
•Connect the master recorder and signal processors as
shown on page 23.
•Set the INPUT selectors (1) of channels 1 -3 to TAPE,
channel 4 to INPUT
•Set all MIX/TRK selectors (6) to MIX, thus placing tracks
1 -3 and the MIDI sound source of channel 4 on the
stereo bus.
•Connect the two additional MIDI sound sources to chan¬
nels 5 and 6 and connect the stereo return of the AUX 1
signal processor to channels 7 and 8, thus placing these
signals on the stereo bus.
•Select only STEREO on the MONITOR selector (16).
•Use the AUX 1 bus to process signals of tracks 1-3 (tape
playback) and use the AUX 2 bus to process signals of the
MIDI sound sources (channels 4-6).
NOTE: Set the AUX 2 send controls (11) for channels 7 and
8 fully counterclockwise to minimum, because these inputs
are used for the stereo return from the AUX 1 signal
processor
•Rehearse as necessary, then record your final mixdown.

ROUTINE MAINTENANCE
In addition to the normal care required of all electronic equip¬
ment, the cassette recorder section of your 280 requires reg¬
ular cleaning and demagnetizing to keep it in top operating
condition.
As the tape passes over the heads and guides, and between
the pinch roller/capstan assembly, a small amount of oxide
residue is left behind. This physical phenomenon is true of all
tapes and all tape recorders.
Cotton swabs and proper cleaning solutions should always
be handy.
NOTE: AVOID CHEAP SWABS THAT ARE SKIMPY IN THE
COTTON
DEPARTMENT—THEY CAN SCRATCH THE
HEAD SURFACES.
The heads, guides and capstan shaft should be cleaned with
anhydrous alcohol solutions; the pinch roller, with special rub¬
ber cleaning solutions. These cleaning agents are readily
available.
NOTE: NO ORGANIC SOLVENTS (such as lacquer thinners)
should ever be used on the heads, capstan shaft and
guides. DO NOT USE SILICONE LUBRICANTS ON THE
PINCH ROLLER! This will increase wow and flutter.
If you get lazy or forgetful and allow the oxide deposits to
build-up, performance will suffer noticeably—especially high-
end response and wow & flutter. If you have total disregard
for these routine maintenance procedures, the heads could
become magnetized and wreck every tape you try to play,
The simplest rule to follow is: CLEAN AND DEMAGNETIZE
BEFORE EVERY SESSION. If you*re in to "all-nighters" and
marathon sessions, do it every 8 hours. (Clean your tape
recorder more often than your teeth!)
NOTE: Use either a hand demag netizer (preferred) or a
demagnetizing cassette and follow the instructions of the
manufacturer But avoid the cassette tapes with built-in or
applied cleaning agents because too many of them contain
an abrasive.
