ART Pro Audio CLEANBox Pro - Dual Channel Level Converter - Manual (Page 4)

INTRODUCTION:
Thanks for purchasing Applied Research and
Technology’s CLEANBoxPro. The CLEANBoxPro
provides two channels of unbalanced to balanced level
conversion and two channels of balanced to unbalanced
level conversion in a rugged, compact, and portable
unit. Balanced lines offer increased immunity to external
electrical noise, such as hum. Since a balanced system
minimizes induced noise, it is the preferred method of
connecting audio gear, especially when long lengths of
cable are used.
One section of the CLEANBoxPro converts two
channels of consumer-level unbalanced input signals
into two channels of pro line-level balanced output
signals. It has two RCA jack inputs and a stereo mini-
phone jack input connected in parallel. The balanced
output feeds two XLR male jacks.
The other section of the CLEANBoxPro converts two
channels of line-level balanced input signals into two
channels of consumer unbalanced output signals. It has
two XLR female input jacks. The unbalanced output
feeds two RCA jacks and a stereo mini-phone jack
connected in parallel.
Each section has stereo level controls to optimize signal
levels. An LED indicator lights when power is applied.
The CLEANBoxPro can be an invaluable tool in
application areas including (but not limited to!): home or
