Rear Panel (D-5.5)

Sum Output jacks

(SUM OUTPUT)

The unbalanced RCA pin jack, 1/4" phone jack and electronical- ly balanced XLR connector are wired in parallel. The RCA jack has a nominal output level of -l0dB and an impedance of 1k ohms, and the 1/4" phone jack has a nominal output level of +4dB and an impedance of 1k ohms. The XLR connector has a nominal output level of +4dB and an impedance of 1k ohms. All jacks may be used simul- taneously.

Ground Lift Switch (GND) These switch are assigned to the XLR Sum Output and Stereo L & R connectors, and are used to avoid ground loops and induced hum that sometimes occur when connecting the D-5.5's XLR Sum Output or Stereo L & R Output with other equipment. Sliding the Ground Lift Switch from the NORMAL position to the LIFT position breaks the ground con- nection and may reduce hum and noise. For most applications the witch should be left in the NOR- MAL position.

Effect Return Jack (EFF RET)

This 1/4" phone jack is used in conjunction with the Effect Send jack to connect an outboard effects device (ie., delay or re- verb) to the D-5.5. The Effect Return jack should be connected to the output of the effect. Nominal input level is — 20dB with an impedance of 10k ohms.

Reverb Return Jack (REV RET)

This 1/4" phone jack is used in conjunction with the Reverb send jack to connect an outboard effects device (ie., delay or re- verb) to the D-5.5. The Effect Return jack should be connected to the output of the effect device. Nominal input level is -20dB with an impedance of 10k ohms. When a plug is inserted into this jack, the built-in reverb circuitry is automatically cut off.

CAUTION - The ground pin on the AC plug should not be re- moved under any circumstances. If the D-5.5 must be used on an AC circuit with no ground or and open ground, then a suitable grounding adapter should be used and its ground terminal should be securely attached to a good earth connection. Failure to do so will result in increased noise and shock hazard.

MIDI Thru Connectors (MIDI THRU)

The MIDI signal from the MIDI Input connector (MIDI IN, A/B) is split and sent unaltered to the four MIDI Thru connectors on the D-5.5, and to six more MIDI Thru connectors on the D-5.5E, if used. Each of the MIDI Thru jacks can be connected to a different synth- esizer's MIDI Input jack, allow- ing one MIDI keyboard or se- quencer to control up to four other MIDI synths. (ten when using the D-5.5E and sixteen when using the two D-5.5E's.)

RCA Phono (RIAA)

Inputs (PHONO)

These RCA pin jacks have a nominal level of — 50dB and an impedance of 50k ohms, and accept input sources from -50dB to +10dB. Proper adjustment of the pad and trim control (PAD/ TRIM) and input fader ensure optimum signal-to-noise ratio and minimum distortion. When using a turntable with magnetic cartridge, place the phono EQ IN/OUT switch on the front panel to the "in" position.

1/4" phone Channel Input (IN-

PUT)

This jack is a standard 1/4" phone jack, with a nominal level of -40dB and an impedance of 100k ohms, and accepts input sources from -40dB to +20dB. Proper adjustment of the pad and tirm control (PAD/TRIM) and in- put fader ensure optimum signal- to-noise ratio and minimum dis- tortion. When a plug is inserted into the 1/4" input jack, the cor- responding XLR mic input or phono input is automatically switched out of the input circuit- ry-

Phantom Power Switches (PHANTOM1~8)

The phantom power switch on each input channel permits the user to supply 48V DC through the input connectors to a conde- nser microphone. If phantom power is not required, the switch must be in the "off" position.

Balanced XLR Microphone In- put

(MIC)

The XLR-type microphone input connectors are electronically ba- lanced with a nominal level of —60dB and an input impedance of 1k ohms, and will accept sig- nals from -60dB to 0dB. Phan- tom powering is provided for use

with condenser-type mic- rophones (see PHANTOM), and once again the proper adjustment of Pad and Trim control (PAD/ RTIM) and Input Fader will in- sure optimum signal-to-noise ratio and minimum distortion. The mic input is automatically disconnected when either the corresponding the 1/4" phone jack is used.

MIDI Input DIN Connectors (MIDI IN, A/B)

These connectors will accept the MIDI output of any synthesizer, sequencer, or other MIDI device. Use of non-MIDI-standard DIN cables, or of cables longer than 5m (16'5") may result in improp- er operation and data loss.
