CONTROLS AND FEATURES
(cont'd.)
[!!]REMOTE IN/OUT terminal
External control input and output terminal. Instead of
using the INPUT SELECT button, an external control
signal changes the INPUT mode. INPUT mode status
data is also output through this terminal.
• The terminal is DIN 8-pin (female).

■
To test external control, short-circuit the REMOTE
ENABLE terminal (Pin No. 1) to the GND terminal (Pin
No. 8) so that the external remote control becomes
valid (L level). Then, turn the SELECT 1 terminal (Pin
No. 2) and the SELECT 2 terminal (Pin No. 3) ON to
select the INPUT SELECT mode.

( Notes: }
• To lest external control, short-circuft the REMOTE
ENABLE terminal (Pin No. 1) to the GND terminal (Pin
No. 8) so that the external remote control becomes valid
(L level). External control doesn't function when external
remote control is invalid (H level).
• The POWER SAVE function doesn't work when external
remote control is valid.
~EXT SYNC terminals (available only for
INPUT A)
Input (IN) and output (OUT) terminals for horizontal
synchronization (HD) or composite synchronization (Cs)
signals, as well as vertical synchronization (VO) signals.
The output terminal is bridge-connected.
• Available only for INPUT A.
* Synchronization signals are automatically detected.
External synchronization is selected when HDND or Cs
is input. The priority is as follows: H DND > Cs.
~AUDIO INPUT terminal
Audio input tenninal (RCA pin-jack).
* The audio input level is 500 mVrms. Sound becomes
distorted when a signal greater than 1 Vrms is input.
§]Ac inlet [AC INPUT]
Power input connector. Connect the provided AC power
cord@].
~Power cord
Provided power cord for connecting the AC inlet IAC
INPUT]@]to an AC outlet (120 V AC, 60 Hz).

CONNECTIONS
• Before connecting your system, make sure that all units are turned off.
• The illustration below shows some examples of different connections. Terminal connections may differ depending on the
component{s) connected. Be sure to refer to the instructions provided with the unit(s) you are connecting.
