Care and Maintenance

주의 및 관리 방법

Your STK VC-23 and VC-34 crossovers are built to provide 
years of dependable service under demanding circumstances. 
It requires no internal maintenance but a common sense 
approach to its use will help you enjoy long and reliable 
operation. Here are some tips:

1. Keep Your Equipment Clean

Keep your unit clean by wiping frequently with a damp, soft 
cloth. Use a mild detergent cleaner if necessary, applied to 
the cloth, not to the crossover. Do not use solvents or other 
chemicals to clean the unit. 
A large clean paint brush is useful to remove accumulated 
dust between the many control knobs on the front panel. 
If liquids are accidentally spilled on to the unit, disconnect 
the power supply cord and allow the unit to dry thoroughly 
before attempting to use it.

2. Connecting Cables

Use only high quality connecting cables with your STK 
crossover. Faulty or suspicious cables should be replaced to 
avoid possible deterioration of sound quality.

3. Check Connections

Recheck cable connections frequently. If you move your 
equipment ofter, cables can become disconnected during 
transport, even when your unit is permanently installed and 
cabled in a rack.

1. 기기를 깨끗하게 유지해 주세요.

클리너를 사용하여 제품 표면을 닦아 주시는 것도 좋습니다. 의류
용 세제는 사용하시면 안됩니다. 솔벤트나 화학 제품 역시 사용하
시면 안됩니다. 
깨끗한 페인트 붓은 제품 구석구석의 먼지를 털어낼 수 있어서 유

모든 연결을 해제하시고 마른 천이나 걸레로 닦아주시기 바랍니다. 
또한, 제품이 완전히 건조되지 않았을 때에는 절대 전원을 넣지 말

3. 연결 상태 확인

케이블 연결 상태를 수시로 확인해 주세요. 간혹 장비의 위치를 옮
