frequency 10 times (70 Hz becomes 700 Hz).
As with the frequency control, improper setting of the range 
switch could cause damage to your speaker
system when power si switched on. If you are using an VC-
23, proceed to step 18.

4. Select Channel A Mid/High Crossover Frequency 
(VC-34 Only)

On the front panel, turn your channel A mid/high frequency 
control to the recommended crossover frequency.
This frequency will be the minimum at which your high 
frequency speaker or tweeter can safely operate.
You may wish to raise that frequency point, however, you 
should never operate below the limit set forth in your speaker 
manual. If you do not know the recommended crossover 
frequency of your speaker systems, you should contact the 
manufacturer or your dealer. Failure to properly set this 
control will cause damage to your speaker systems. By setting 
this control, you have now routed the frequencies above the 
selected crossover point to the high frequency output of the 
VC-34 frequencies below the crossover point will be sent to 
the mid frequency output.

5. Check Frequency Range Selector Switch

The yellow indicator light will indicate the crossover 
frequency range selector switch is in the "in" position once 
power has been switched on. Check this for the proper 
setting of your selected crossover frequency. 
Remember, the ×10 switch multiplies the selected crossover 
frequency 10 times (70 Hz becomes 700 Hz).

Note: 

Steps 18 through 20 refer to mono subwoofer operation. If 
you do not intend to use the subwoofer section, set the input 
and output level controls at minimum and keep them at this 
setting.

6. 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.

7. Select Subwoofer Crossover Frequency

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

그러나, 주파수 포인트를 올리고 싶더라도, 스피커 매뉴얼 대로의 
설정 값을 조정하여서는 안됩니다. 만약 스피커 시스템에서의 권장 
크로스오버 주파수를 모르신다면, 스피커 제조사나 담당 판매자에
게 문의하여 주십시오.
본 설정을 적절하게 하지 못할 경우 스피커 시스템에 손상이 생길 
수 있습니다.
본 설정은 크로스오버 주파수 포인트로부터 VC-34의 중주파 출력
으로의 통로를 만들게 되는 것입니다. 크로스오버 포인트 이하의 
주파수는 저주파 출력으로 나가게 됩니다.

5. 주파수 범위 선택 스위치 확인

노란색 표시등은 크로스오버 주파수 선택 스위치가 눌려진 상태일 
때 켜지게 됩니다. 크로스오버 설정을 하기 전에 먼저 표시등이 점
등되어 있는지 확인해 주세요.
x10 스위치는 선택된 크로스오버 주파수를 10배로 높인다는 것을 
기억하세요.(70 Hz 는 700 Hz가 됩니다).

참고사항: 

18번부터 20번까지의 단계는 모노 서브우퍼 동작에 관한 설명입
니다. 만약 서브우퍼를 사용하지 않으신다면 입,출력 레벨 컨트롤
을 최하로 낮춰주시고 그 설정을 유지하여 주십시오. 

6. 모노 서브우퍼 출력

모노 서브우퍼 설비를 사용할 때에는 위에 설명한 것과 같이 크로
스오버의 출력을 서브우퍼 앰프의 입력으로 연결하세요. 연결을 마
치셨다면, 서브우퍼 앰프의 출력을 서브우퍼 스피커 시스템의 입력
으로 연결하여 주십시오.

7. 서브우퍼 크로스 오버 주파수 선택

서브우퍼 크로스오버 주파수의 선택은 고, 저주파 조절기로 할 수 
있습니다. 
서브 우퍼 스피커의 매뉴얼이나 서브우퍼 후면의 최적 크로스오
버 설정값을 참고하여 크로스오ㅂ 주파수를 설정하여 주십시오. 
만약 아무런 설정값에 대한 정보가 없다면, 크로스오버 주파수를 
150Hz로 설정하여 주십시오.

8. 하이-패스 필터 동작준비

STK 크로스오버에는 서브우퍼 섹션에 하이패스 필터가 내장되어 
있습니다. 이 필터는 15Hz 미만의 신호는 깔끔하게 깍아내 줍니
다. 그런 낮은 주파수 스펙트럼에는 귀로 들을 수 있는 소리가 거의 
없기 때문에 이 필터를 사용하게되면, 과한 저주파로 인한 서브우
퍼의 손상을 막을 수 있습니다.  
하이패스 필터를 동작시키려면, 하이패스 스위치를 눌려진 상태가 
되도록 해주세요.

9. 시스템 게인

계속하기 전에 본 매뉴얼의 “전문적인 동작을 위한 팁” 부분을 읽
고 따라 주세요. 사운드 시스템을 동작시킬 때 각 장비의 게인 구조
와 순서를 이해하는 것은 매우 중요합니다. 특히 이 장비를 사용할 
때에는 더더욱 그렇습니다.
위 섹션에서 올바른 게인 조절 절차를 알려드리겠습니다. 22번 단
계에 설명된 것과 같이 시스템의 전원을 올리시고 신호 기기에 따
른 전체 시스템에서 크로스오버까지의 각 레벨과 게인 구조를 설립
하여 주십시오.
