3. BALANCED XLR, PHONE INPUTS

3. 입력단자

감전의 위험이 있으니 스피커 결선 작업을 하기전에 반드시

기기의 전원을 꺼주시기 바랍니다.
스피커 결선시에는 극성에 주의 하십시오.
스피커 결선시에는 전력 손실과 댐핑팩터를 높이기 위하여
충분히 굵은 선을 최단거리로 결선 하십시오.

4. 출력단자

3

Normal input level is 1.6V (+4dBu) 15K    balanced with channal 

A,B XLR and 1/4" phone jack input terminal for the extension to 

another amplifier connect link jack to another amplifier input jack.

바란스형 입력잭으로서 입력 감도는 +4dBu(1.6V) 15K

입니다.

4. SPEAKER CONNECTORS

Turn the amplifier off befor touching the output connection.

WARNING

To prevent electric shock do not operate the amplifier with 

any of the conductor portion of the speaker wire exposed.

SPEAKER CABLING

Larger wire sizes and shorter lengths minimize both loss of 

power and degradation of damping factor. 

Do not place speaker cables next to input wirning.  

5. MODE SELECTOR

BRIDGE MONO

STEREO

Both channels operate separately : for stereo or 2-channel

operation, speaker impedance for each channel at least 4    .

Both channels are connected as a bridge : for a speaker

impedance of at least 8   .

5. 운용모드

스테레오

브릿지 모노
채널A+ 콘넥터를 스피커+단자, 채널B+콘넥터를 스피커-단자와
연결하여 출력을 증강하기위한 방식으로 신호 입력을 채널A에만

각 채널이 분리되어 운용할 경우에 사용되며 스피커 최소 부하는
4

입니다.

공급합니다. 스피커 최소 부하는 8

입니다.
