G. INPUT/OUTPUT CONNECTIONS

The STK, VS-2004/VS-1204 and VS-2003/VS-1203 power 

amplifiers are designed to be as versatile as possible. The 

following descriptions of the input and output connections 

are designed to help you maximize the unit's potential.

1. XLR Input Jacks / Through Jacks

Electronically balanced input accepts a standard XLR male 
and female connector.

Pin1=ground, Pin2=hot or positive (+). 
Pin3=cold or negative (-).

G. 입출력 단자 연결

STK VS-2004/VS-1204/VS-2003/VS-1203 파워 앰프는 가능한 다
양한 응용이 가능하도록 설계되었습니다. 다음의 입출력 연결에 
대한 설명은 기기의 활용을 극대화 할 수 있도록 도와줄 것입니다.

1. XLR 입력 잭 / 입력신호 XLR 출력잭

전기적으로 밸런스드 입력신호 용인 표준규격의 XRL
돌출형과 함몰형 컨넥터를 연결합니다.

2. Speaker Outputs

Speaker connections are speakon jacks and dual banana 
MDP/bare wire binding posts. The binding posts that will 
accept a standard dual banana plug or bare wire. Either 
method provides a safe and reliable connection capable of 
transferring high power signals if properly connected. 

To avoid ANY possible shock hazard, the power amplifier 

should be disconnected from the AC power source before 
making any connections. When connecting your speakers 
using either method, be sure to pay close attention to proper 
polarity. Although connecting your speaker systems out 
of phase using the wrong polarity will not damage your 
speakers, it will affect the quality of sound.
When using bare wire connections, be sure that your 
connections are "clean". If any strands of wire from one 
connector are allowed to touch the adjacent connector, 

damage to your amplifier and sound system could occur.

H. POWER REQUIREMENTS

Your STK VS-2004/VS-1204 and VS-2003 /VS-1203 are pre-
wired at the factory for the correct line voltage (120V or 220-

240V) and is furnished with the appropriate power cord and 

fuse. If fuse replacement is necessary, always use a fuse with 

the exact type and rating as specified on the specifications 

page of this manual or as indicated on the unit itself.

2. 스피커 출력

스피커 연결은 베어 와이어(연심투명선) 바인딩 포스트나 speakon 
연결단자 모두 사용할 수 있습니다.
연결이 잘 되어 있다면 두 방식의 연결 모두 안전하고 
확실하게 높은 파워의 신호를 전달합니다.
가능한 모든 사고를 예방하기 위해서 연결이 확실히 이뤄지기 전
에는 절대 전원을 연결하지 마십시오.
또한, 어떤 방식의 연결을 선택하셨던 간에 올바르게 극성을 연결
하도록 주의를 기울이십시오.
극성을 잘못 연결했음에도 불구하고 스피커에 손상을 입히지 않
는다면 반드시 음질에 문제가 생길 것입니다. 
베어 와이어(연심투명선)를 사용하여 연결할 경우 간단하고 깔끔
하게 연결이 잘 되었는지 확인해야 합니다.  
만약 한 가닥이라도 접속단자에 인접하여 단자를 건드리게 된다
면 앰프에 손상을 입힐 것이며 다른 사운드 시스템에도 손상을  
입히게 됩니다.

H. 요구되는 전력

STK VS-2004/VS-1204/VS-2003/VS-1203 은 생산 단계에서부터 
정격전압(120V or 220-240V)에 적합하도록 되어 있으며 전원 코
드와 퓨즈가 함께 제공됩니다. 퓨즈의 교환이 필요할 경우 반드시 
제품과 사용 설명서에 기재되어 있는 동일한 타입의 퓨즈를 사용
하시기 바랍니다.
