Hookups and Cabling:

The HVQ series equalizers are designed for n4dBu 
levels. The equalizers can be used with either balanced or 
unbalanced sources, and the outputs can be used with either 
balanced or unbalanced loads, provided the proper cabling is 
used.
A balanced line is defined as two-conductor shielded cable 
with the two center conductors (Hot ,Cold) carrying the same 
signal but of opposite polarity when referenced to ground. 
An unbalanced line is generally a single-conductor shielded 
cable with the center conductor carrying the signal and the 
shield at ground potential.

Input Cable Configurations:

The equalizer has an input impedance of 40Kohm balanced 
and 20Kohm unbalanced. 
This makes the HVQ series equalizers' audio inputs suitable 
for use with virtually any low source impedance
(under 2Kohm).

Output Cable Configurations:

The equalizer's output is capable of driving a 600 Ohm load 
to +22dBu. For maximum hum rejection with a balanced 
source, avoid common grounding at the equalizer's inputs 
and outputs. 
Most balanced(3-conductor) cables have the shield connected 
at both ends. 
This can result in ground loops which cause hum. 
If hum persists try disconnecting the shield on one or more  
of the cables in the system, preferably at the input of a device, 
not at the output.

다른 기기와의  케이블 연결:

HVQ  시리즈  이퀄라이저는  입출력레벨을  +4dBu  기준으로 
설계되었습니다.  본  이퀄라이저는  밸런스드  또는  언밸런스드 
신호와 함께 사용될 수 있으며 출력 또한 적절한 케이블 연결이 된 
밸런스드, 언밸런스드와 함께 사용될 수 있습니다. 
밸런스드 라인은 쉴드 그라운드와 함께 2개의 서로 극성이 다른 
(HOT+,  COLD  -  )단자로  접속되며  2개의  단자는  동일신호를 
전달합니다. 언밸런스드 라인은 일반적으로 쉴드접지단자와 함께 
하나의  극성  (HOT,+)으로만  접속되어  신호를  전달하는  싱글 
컨덕터 케이블입니다.

입력 케이블 구성:

본 이퀄라이저는 입력 임피던스를 밸런스드 40Kohm, 언밸런스드 
20Kohm을 갖고 있습니다. 
이는 HVQ 시리즈 이퀄라이저를 어떠한 낮은(2Kohm 이하) 
인피던스를 갖는 기기와 연결하여 사용하더라도 신호손실이 없도 
록 하면 다른 접속기기에 무리가 없도록 최적화하고 있습니다.

출력 케이블 구성:

본 이퀄라이저는 600 Ohm의 부하조건에서 +22dBu 출력레벨을 
갖습니다.  밸런스드  신호접속에서  최대의  노이즈  제거는 
일반적으로 이퀄라이져의 입력과 출력케이블 모두를 접지시키는 
것은 피하기를 권합니다.
대부분의  밸런스드  케이블(3번접속단자)은  양쪽  끝이  실드와 
연결되어 있습니다. 이는 잡음을 야기하는 그라운드 루프의 원인이 
됩니다. 만약 잡음 현상이 발생한다면 시스템과 연결된 케이블중 
하나 혹은 그 이상의 실드와 연결된 끝을 끊어주십시오. 되도록 
출력이 아닌 입력부 케이블에서 시도하십시오.
