12. Mono Subwoofer Output

If you will use the mono subwoofer facility, connect the 
subwoofer output of your crossover to the input of your 
subwoofer amplifier as described above. If you haven't already 
done so, connect the subwoofer amplifier output to the input 
of your subwoofer speaker system.

13. Select Subwoofer Crossover Frequency

Select the subwoofer crossover frequency as you did with the 
high through low frequency controls. 
Consult the manual supplied with your subwoofer or look 
at the back plate on the speaker to determine the optimum 
crossover setting. If no information is available, set the 
crossover frequency to 150 Hz.

14. Engage Hi-Pass Filter

Your STK crossover is fitted with a high pass filter in the 
subwoofer section. This filter sharply rolls off the signal 
below 15 Hz. As there are no audible sounds located that low 
in the frequency spectrum, using this feature will protect 
your drivers from subsonic, over-excursion damage. To 
engage the high pass filter, depress the high pass switch to 
the "in" position.

15. System Gain

Before proceeding, refer to section "Professional Operating 
Tips" in this manual. It is important that you understand 
proper gain structure procedures when using any sound 
system. but it is of particular importance when using 
this device. This section will help you learn correct gain 
adjustment procedures. Once you have powered up the 
system as described in step 30, establish the levels and gain 
structure for your whole system up to the crossover per the 
instructions for your source devices, mixing console and 
other signal processing.

16. Switching On Power

At this time, you may now switch on all equipment up to and 
including your crossover, but do not switch on the power 
amplifiers. Before doing so, check once more that the input 
and output level controls on the crossover are turned hard 
left, or off position. As you are operating in the mono mode, 
the mono mode indicator light on your VC-23 or VC-34 
should be illuminated.

17. Set Input Level Controls

Now you are ready to make the level adjustments for your 
VC-23 or VC-34. With your amplifiers still off, play some 
program material from your source. The signal from your 
last piece of equipment such as a graphic equalizer should be 
strong. With your program material reaching the occasional 
peak, slowly turn up the input level control for channel A, 
which serves as the mono input. Increase the level until you 
see the red peak indicator located on the front panel begin to

위 섹션에서 올바른 게인 조절 절차를 알려드리겠습니다. 30번 단
계에 설명된 것과 같이 시스템의 전원을 올리시고 신호 기기에 따
른 전체 시스템에서 크로스오버까지의 각 레벨과 게인 구조를 설립
하여 주십시오.

16. 전원 넣기

이번에는 파워앰프를 제외한 크로스오버를 포함한 모든 장비의 스
위치를 켜주십시오. 물론 그전에 모든 입력 기기와 출력 기기의 볼
륨 조절기가 최하의 위치로 되어있는지 한번더 확인해 주십시오. 
현재 모노 모드를 사용하고 있으므로 모노 모드 표시등이 켜져야 
합니다.

17. 입력 레벨 조절기 설정

앰프의 전원이 여전히 꺼져있는 상태에서 VC-23과 VC-34의 레
벨 조절을 할 준비가 되어 있다면, 신호 기기를 동작 시켜 주십시
오. 그래픽 EQ와 같은 마지막 장비의 신호는 꽤 강력할 것입니다. 
신호 기기가 이따금 피크에 도달하면, 모노 입력으로 신호를 전달
하는 채널 A의 레벨 조절기를 낮춰 주십시오. 그리고 다시 전면부
의 붉은색 피크 표시등이 깜박일 때까지 천천히 레벨 조절기를 올
려 주십시오. 이것은 단지 프로그램 피크에 대한 것입니다.  
이제 입력 레벨 조절기는 올바르게 설정되었습니다.

18. 출력 레벨 조절기 설정

크로스 오버의 유니티 게인 위치(유니티 게인이란 입력 레벨과 출
력 레벨이 동일한 게인을 말합니다.)는 출력 레벨 조절기의 "0"위치
입니다. 그 부분에 조절기가 살짝 걸리는 부분이 있습니다. 올바른 
게인 구조를 유지하기 위해 출력 조절기를 이 위치 또는 "0"의 위치
에 두고 시작하셔야 합니다. 추가적인 조절은 차후에 필요하게 될 
것입니다.

19. 파워 앰프 연결 재확인

앰프의 전원을 켜기 전에 입력 기기들과 스피커들의 연결 상태를 
다시 한번 확인해 주십시오. 
모든 연결이 확인 되었다면, 앰프의 입력 레벨이 여전히 가장 낮은 
위치로 되어있는지 확인하여 주십시오. 확인이 끝나면, 모든 앰프
의 전원을 켜 주십시오. 

20. 앰프 입력 레벨 조절기 설정

일반적으로 파워 앰프로 신호를 입력하는 기기가 앰프를 최대 파워
로 동작 시킬 수 있을 만큼 충분한 출력 게인을 가지지 못했다면 파
워 앰프의 레벨 조절은 최대로 할 필요가 없습니다. 
VC-23, VC-34는 많은 출력단을 가지고 있습니다. 시스템을 테스
트할 때는 올바른 시스템 설정과 균형을 확보할 때까지 앰프 레벨
을 다른 기기에 비해 낮게 유지해 주십시오. 
이를 통해 갑작스러운 과신호로부터 스피커 시스템을 보호할 수 있
습니다. 

21. 음소거 스위치

음소거 스위치는 시스템 설치 시 유용한 도구가 될 수 있습니다. 
VC-23은 스테레오 동작 모드에서 저주파 출력 을 음소거 할 수 있
습니다. VC-3은 저주파, 또는 중주파, 그리고 저, 중주파 모두 음
소거 할 수 있습니다. 
STK 크로스오버에는 서브우퍼 섹션을 포함하여 각 채널마다 음소
거 버튼이 있습니다.
