1. 입력 조절기

이퀄라이져의 입력신호 레벨을 조절합니다. 입력 게인(이득)을 
-12dB 에서 +12dB범위까지 변화시킬수 있으며 신호레벨 크기는 
바 그래픽 출력레벨메타로 표시됩니다. EQ의 각 밴드 별 부스트와 
컷으로 인한 게인(이득) 변화에 대한 전체적인 메인 출력레벨을 조
절하는데 사용하세요.

2. 부스트/컷 레인지 선택 스위치와 표시등

이 스위치는 ±6dB 또는 ±15dB 두 개의 부스트/컷 범위 중 이퀄
라이저가 사용할 것을 선택하는 스위치입니다. 매우 정밀한 부스
트/컷 조절을 원한다면 ±6dB 레인지를 선택하세요.
±15dB 범위가 선택될 경우 붉은색 표시등이 ±6dB범위 선택 시 
노란색 표시등이 점등됩니다. 
부스트/컷 스위치는 서서히 꺼집니다. 이는 다른 사운드 시스템에 
손상을 줄 수 있는 경우를 방지하기 위해서입니다.

1. Input Gain Control

This control sets the signal level to the equalizer. It is 
capable of -12dB to +12dB of gain. The signal level amounts 
indicated on the output level BAR GRAPH.
This control is used to compensate for variations in volume 
due  to  gain  changes  caused  by  equalizing  individual 
frequencies

2. Boost/Cut Range Selection Switch and LEDs

This switch selects which of the two boost/cut ranges the 
equalizer will use, either ±6dB or ±15dB. 
The red LED lights when the ±15dB range is selected, and 
the yellow LED lights when the ±6dB range is selected 
and the ±6dB boost/cut range are provided for higher 
precise slide controls. Note that the boost/cut switch is 
slightly recessed. This is to prevent accidental activation of 
the switch, possibly causing damage to other sound system
