1. Dimensions and Schematics

Operating Manual - DPX-200 Parametric Equalizer - Compressor/Limiter

When Using Heavy Compression, Background Noise Is Noticeable During Quiet Sections Of The Program

As defined in the section on compression, quiet program material is effectively made louder while loud peaks

are made quieter. When the program source is thus raised in volume, its noise floor is also raised in volume by a

proportionate amount. This is not a defect in the compressor/limiter, but an unavoidable side effect of the gain altering

process. If the noise becomes a problem, the solutions are to either decrease noise at the program source, or use less

compression.

Excessive Hum Or Noise

Hum is often caused by a "ground loop" between components. Try using the suggested balanced input and

output hookups if the other pieces of equipment used in conjunction with the DPX-200 have balanced inputs and

outputs. Noise can also be caused by insufficient drive levels. Make sure you are sending a nominal 0 dBV line level

signal to the unit.
