Wired Remote Control Box Circuit Diagram
L - CH : Vcc (5 VOLT)
R - CH : SIGNAL
SW001 ~ 008: Momentary Contact
SW101, 102: Toggle Switch
Second and Subsequent Units
SW 008 DECK A/B
DECK SELECTOR button
Press this button to select either Deck A or Deck B to be
controlled.
• Make a control box using the supplied remote control box connection wire.
• Do not connect the left channel of the plug (Vcc) with 8001 (200 ohm) in the second and subsequent units.
• Use resistors having a tolerance of within ±5% (1 /4W).
Use of resistors having a poorer tolerance will cause incorrect operation.
• Never short circuit the left-channel line (Vcc). Doing so will damage the main unit.
2.
Operation with Parallel Connections
A number of DN-770R units can be simultaneously operated in parallel with 1 button.
Operation with parallel connections can be used with a maximum of 5 units.
Connection of 6 or more units will lead to incorrect operation.
3.
Cable Length
The longer the length of the cable, the more susceptible the system will be to the effects of external noise.
Keep cable lengths to 2 m or less.
Do not locate equipment that produces electrical noise in the vicinity of the cable.
Doing so might lead to incorrect operation due to the noise.
4. Do not disconnect or connect the remote control plug during operation of the unit.
The pins of the plug might cause a short circuit of the pins inside the jack which can stop the operation.
5. Pressing more than one button of the wired remote control box at the same time (for combined operations) is not possible. A music search
operation will not result from pressing the PLAY and FF, or PLAY and REW buttons at the same time.
6. Pressing a button of the wired remote control box and a button of the main unit,
DN-770R
, (for combined operations) is not possible.
7. When multiple sets are connected to a single remote box, the other sets may operate erroneously when this set’s power is turned on or off or
when the cord is connected or disconnected from the remote control jack.
Turn off the remote control box’ toggle switches (SW101, 102,…) when turning this set’s power on or off or when connecting or disconnecting
the cord from the remote control jack while other sets are connected to the remote control box.
