Placement Tips & Hum

HUM

*Turn the LEVEL control all the way down.

If the noise disappears, it's coming from the signal source. 
If not, try disconnecting the cable connected to the INPUT 

jack. If the noise disappears, it could be a "ground loop", 

rather than a problem with the active speakers.

Try some of the following troubleshooting ideas:

*Use balanced connections throughout your system for the 

best noise rejection.

*Whenever possible, plug all the audio equipment's line cords 

into outlets which share a common ground.
The distance between the outlets and the common ground 
should be as short as possible.

*The hum may appear when using an unbalanced 

source(consumer preamps, CD player, VCR, etc.).

This is caused by the unbalanced-to-balanced interface 

between the devices(and exacerbated by the fact that most 
consumer audio equipment have a two-wire line cord, 
without the third-pin safety ground).

Use an interconnect cable wired as shown below. The 
important point is that the shield and wire from the XLR pin 

3 are jointed at the RCA(source)end.

험 현상

*모든 볼륨 조절기를 최소로 하고 전원을 켜십시오.
만약 노이즈가 사라진다면 이 노이즈는 입력 신호로부터 나타난 
것입니다. 그렇지 않다면, 입력 잭에 연결된 케이블의 연결을 끊어 
주십시오.
그 경우 노이즈가 사라진다면 그것은 액티브 스피커에 의한 것이
라기보다는 “그라운드 루프”라고 볼 수 있습니다.
다음의 문제해결 방법을 시도해 보십시오.
*밸런스드 연결을 사용해 보십시오.

*가능하다면 언제든 오디오 기기의 모든 코드 선들을 동일한 접지
를 공유하는 콘센트에 끼워 보십시오. 콘센트와 공통 접지 사이의 
거리는 짧을수록 좋습니다.

*험 현상은 언밸런스드 입력(소비자 프리앰프, CD 플레이어, VCR 
등)을 사용 할 때 나타납니다.
이는 기기들(그리고 접지 핀이 없는 두가닥 선 코드를 가진 오디오 
기기로부터 악화된 것들) 사이에서 언밸런스드에서 밸런스드로 
접촉하면서 야기되는 것입니다. 아래에 나온 것처럼 인터컨넥트 
케이블 와이어를 사용하십시오. 중요한 것은 XLR 핀 3에서의 실
드와 와이어는 RCA(입력신호)엔드와 접합되어 있다는 것입니다.

*바룬은 TV동축 케이블에 맞도록 한쪽 끝(75옴)이 꼬이고 다른 쪽 
끝(300옴)은 두 개의 와이어를 가진 것입니다. 이것들은 비디오의 
퀄리티에 영향을 주지 않습니다.

*험 현상이 지속되면 믹서나 프리앰프의 뒤로부터 즉시 구성기기
들을 제거해 보십시오. 그리고 매번 험 형상을 체크해 주십시오(연
결을 끊기 전 전원을 꺼 주십시오).
이는 문제를 찾아내는 가장 일반적인 방법입니다.

*프리앰프 또는 믹서만이 액티브 스피커에 연결되어 있는데 험 현
상이 여전히 발생한다면 다른 연결 케이블을 사용해 보시거나 프
리앰프나 믹서의 위치를 옮겨 보십시오.

*The baluns are threaded at one end(75 ohm) to fit TV coax 

cable and have two wires at the other end

(300ohm). They will not affect the video quality. 

*If the hum persists, try removing components one at a time 

from the back of the mixer or preamplifier, and
check for hum each time(turn off your equipment before you 
undo any connections).
It is fairly common to find more than one problem. 

*If your preamp or mixer are the only things connected to 

the active speaker and the hum is still there,

try different connection cable, or move the preamp/mixer to 

another location.
