CHAPTER I:
The DX21 has two audio outputs, one for each tone generator channel. These
are labelled MIX/A and B. When a plug is plugged into the MIX/A output only,
the sound from both the A and B tone generator channels will be mixed and delivered
via the MIX/A output. When plugs are inserted into both MIX/A and B jacks,
however, the channel A signal will be delivered via the MIX/A output and the
channel B signal will be delivered via the B output. This permits sending a stereo
signal to a stereo sound system giving you the full impact of the DX21's dual and
split play mode capability.
The remaining three phone jacks are for optional foot controllers and footswitches.
The VOLUME jack accepts a Yamaha FC-7 or equivalent foot controller for volume
or "swell" control. The SUSTAIN jack accepts a Yamaha FC-4 or FC-5 footswitch
or equivalent for sustain control–press for sustain, release to damp. And the
PORTAMENTO jack also accepts a Yamaha FC-4 or FC-5 footswitch or equivalent
permitting ON/OFF switching of the programmed portamento effect.
Yamaha's unique BC1 breath controller is plugged into the mini-jack on the rear
panel.
The PHONES jack accepts any standard pair of stereo headphones. When a plug
is plugged into the B output only, the channel A and channel B signals are delivered
to the headphones in stereo. When the B output is not connected, both A and B
signals are mixed and output from PHONES jack. Headphone volume is controlled
via the VOLUME control on the top panel.
These terminals are used when connecting the DX21 to other MIDI (Musical In-
strument Digital Interface) compatible equipment such as digital sequence re-
corders, modular FM voice generators, drum machines, etc. The MIDI OUT terminal
transmits MIDI data from the DX21 to other MIDI equipment. The MIDI OUT
terminal will normally be connected to the MIDI IN terminal of the receiving
equipment. The MIDI IN terminal accepts MIDI data from external MIDI equipment
such as a digital sequence recorder, music computer or modular FM voice generator.
THe DX21's MIDI IN terminal will normally be connected to the MIDI OUT terminal
of the transmitting equipment. The MIDI THRU terminal re-transmits the data re-
ceived at the MIDI IN terminal. Thus, data received via the DX21 MIDI IN terminal
can be simultaneously sent to other MIDI equipment.
The DIN connector end of the supplied cassette cable is plugged into the DX21
CASSETTE connector. The three plugs on the other end of the cable should be
connected to a cassette data recorder (the kind normally used with personal
computers, etc.) as follows:
RED cassette deck microphone input.
WHITE cassette deck earphone output.
BLACK cassette deck remote input (The DX21 does not output cassette
remote control signals, so this jack may be left unconnected).
