1. AC INLET

After turn off "Power switch" on Front panel, please plug "Power cord".

2. AC POWER REMOTE

This is connector for AC Power Remote control.
When this connector is short, AC power is "on" and when this 
connector is open, AC power is "off".

3. DC POWER

This is connector for connecting outer DC 24V battery.
Please be careful for the polarity of a battery and connect "-" first.

 

전면 스위치가 “OFF”된 상태에서 전원 코드를 연결하여 주십시오.

1. 교류 전원 공급 소켓

외부에서 전원을 제어하는 단자입니다.
두단자가 쇼트되면 전원이 “ON” 되며, 오픈되면 전원이 “OFF”됩니다.

2. 파워 리모트 단자

외부 24V 배터리와 연결되는 단자이며, 연결시에는 극성에 주의하여
“-”단자를 먼저 연결 하십시오.

3. 배터리 연결 단자

앰프 출력 신호는 접지와 절연되어 있으며, 스피커 연결시에는  앰프의
출력 임피던스 보다 스피커의 합성 임피던스가 높아야 합니다.
JDB-250,225 : 100V / 40
JDB-500 : 100V / 20

4. 출력 단자

AC OK: 포토 커플러 출력으로 이루어져 있으며, AC 전원이 공급대기 
상태에서 "ON" 됩니다.

5. AC OK, BATT OK, PILOT TONE

4. OUTPUT

Amplifier's Output signal is isolated from the Ground.
When connect with Speakers, total impedance of Speakers should 
be higher than Amplifier's output impedance.
JDB-250 : 100V / 40
JDB-500 : 100V / 20

5. AC OK, BATT OK, PILOT TONE

AC OK: This consist of  photocoupler and will be turn on under condition 
of standby status of AC power. 

BATTERY OK: 포토 커플러 출력으로 이루어져 있으며, 배터리 전원이 
연결되면  "ON" 됩니다.

BATTERY OK: This consist of  photocoupler and will be turn on when the 
battery power is supplied.

PILOT TONE: 외부의 파일로트 톤 신호를 입력하는 단자입니다.

PILOT TONE: This is connector to enter the signal of external PILOT TONE.
