CHAPTER I: SETTING UP

1. Audio Outputs
2.Optional Foot Controllers & Foot
Switches
3.Optional BC1 Breath Controller
4.Headphones

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.

5. MIDI Terminals
6. Cassette

These terminals are used when connecting the DX21 to other MIDI (Musical Instrument 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 received 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).
