Safety 

Do not remove the grounding. It is for your safety. If you remove the grounding it can cause electric 

shocks. 

 

Hearing 

To avoid hearing damages, you should not operate a sound system with high levels. This applies to 

monitor systems, which are in the near of the ear, headphones or IEMs also. 

 

Accessory  

Please use only the accessory which is set by the manufacturer.  

 

Important 

 

Damages caused by the disregard of this user manual are not subject to warranty. The dealer will not 

accept liability for any resulting defects or problems. Make sure the electrical connection is carried out 

by qualified personnel. All electrical and mechanical connections have to be carried out according to 

the European safety standards. 

 

2.  Introduction 

 

Congratulations on your purchase of the compressor/Limiter. Te unit was designed to meet the need 

for universal peak-sensitive automatic gain control (AGC) devices with exceptional audio performance 

and rugged durability. The unit has the following key features.  

 

Treshold control 

 

Input/output meter with select switch 

 

Balanced XLR connectors 

 

A single TRS patch point detector loop 

 

Premium components throughout 

 

Quality construction through computerized, automated assembly  

 

We are confident that you will be pleased with the high performance, superb sound quality, and 

reliability that we are known for.  

2.1. What compressors and limiters do 

 

Limiting 

 All musical programs have constant changes in loudness. It is the job of a limiter to 

detect when the volume has exceeded a predetermined maximum safe level, and to 

turn down the volume. When the incoming signal returns to its original level, the limiter 

should respond by restoring the gain to normal. Thus, when the level is within a 

specified ‘safe’ range, the limiter has no effect. When an occasional peak occurs, the 

limiter responds.
