CleanBoxPro - ARTcessory
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 professional recording studios, live sound, PA,
permanent installs, DJ, AV, consumer HiFi, podcasting and broadcasting. The
CleanBoxPro can be used with: mixers, audio processors, laptop computers,
computer sound cards, CD/DVD players, video gaming machines, MP3
player/recorders, powered monitors and digital audio workstations.
