DP-0202 DP-0204

Input boost switch 

[INPUT]

This switch simultaneously boosts the analog signal

level of each input by 6dB. When the input signal level

is low, signal processing that provides good S/N ratio

can be achieved by using this switch.

Input mode selection switch

 [DIGITAL ANALOG]

Either analog or digital mode can be selected for input

signals.

Output attenuation switch 

[OUTPUT]

This switch individually attenuates the analog signal

level of each output by 6dB or 12dB. More residual

noise can be reduced for sound output with a good S/N

ratio.

Output mode selection switch

[DIGITAL  ANALOG]

Either analog or digital mode can be selected for output

signals.

Communications port selection switch 

[PORT]

This switch is used to select the communications port

your computer is connected to.  RS-232C is valid only

when controlling a single  unit, and the front or

rear-mounted  D-SUB connector can be used. Use

RS-485 when controlling multiple units. XLR connectors

for RS-485 are mounted on the back of the unit.

System locking switch 

[LOCK]

Use this switch to set how the hardware is locked.

OFF : All  functions  are  available (unlocked), such as

memory switching.

1 : All  functions  are  locked  except  memory

switching.

2 : All front panel facilities are locked.

Make sure the power is switched ON when you use this

switch.

Word clock switch

 [WORD  CLOCK]

For most operations, set this switch to the "INT"

position. When controlling an internal signal processing

clock from external equipment, set this switch to the

"EXT" position.

RS-232C communications port 

[RS-232C]

This is a 9-pin D-SUB connector for RS-232C

communications, and can only be used when the

communications port selection switch is set to

"RS-232C". This port is connected in parallel to the

rear-mounted D-SUB connector for RS-232C. For

details, refer to p. 6 "6. PERSONAL COMPUTER

CONNECTIONS".

Unit ID number setting switch

[SET UNIT ID No.]

Use this key to set the unit ID number. For details, refer

to p. 8  "7. UNIT ID NUMBER SETTING".
