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.
JDA-250 : 100V / 40
JDA-500 : 100V / 20

4. 출력 단자

입력신호가 없을때, 소비전력을 저감시키는 슬립기능의 모드 선택 
스위치입니다.
PRE MODE
20Khz pilot tone에 상관없이 무신호시에 sleep 기능이 작동됩니다. 

20Khz pilot tone에 의해 입력이 무신호일지라도 sleep기능이 
작동하지 않습니다.

5. SLEEP MODE

400Hz 저역 차단 필터의 기능을 “ON/OFF”하는 스위치입니다.

6. 400Hz 저역 차단 필터

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.
JDA-250 : 100V / 40
JDA-500 : 100V / 20

5. SLEEP MODE

PRE MODE

This is mode select swtich of sleep function lowering the power
consumption when there is no input signal. 

Regardless of 20Khz pilot tone, the sleep function is operated under 
no signal condition.

POST MODE

Even if the input is under no signal condition by 20Khz pilot tone, 
the sleep functino is not operated.  

6. 400Hz LOW-CUT FILTER

This is "On/Off" switch for cutting low frequency below 400Hz.
