UTILIZATION

The machine heats up and need to be are! configuration and simple and effective, there is a pumping effect is compressed as a strong background noise (lamps!)

SOUND QUALITY

Compression is very effective, with good audio quality. Produced a noise not ngligable!

I use it with the voices and instruments.

OVERALL OPINION

I use it for two months, its background ESG me, especially for use in mastering!, Compression is very effective and the sound is very clear.

I can not compare because I have no other machine of the same type.

Do not sell the newer, only on the second hand market.
