ART CLEANBoxPro Overview

The ART 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 used 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.

Works great.

Does exactly what is is supposed to do. Any balanced input to any unbalanced output. Any unbalanced input to any balanced output. By connecting like input/output together you can create a mono line level control. (must use both volume controls) I used it to connect my iPhone to my balanced input PA system. I recommend this item.

Clean Box Pro Good for converting XLR output to RCA input

Works Very well. I needed to place between my( Pro Gear) Behringer Mixer XLR output to my (Consumer Gear) amplifier RCA input. Turned the needle to 1/3 way up and awesome sound from my speakers. No more noises! Awesome product. I am using for karaoke. The Clean Box Pro is excellent in converting from my mixer XLR output to the amplifier RCA input.

Excellent

Bought because I was having an issue with audio buzz when recording from a Pro Audio Mixer to consumer video camera. It did take most of the buzz out. I still had to enhance the audio to get rid of a little. But it did same some time and easy to use.

This Cleanbox was just what I needed to connect my video camera to a soundboard. I was getting humming even with a ground loop isolator. This CleanBox alone took care of that problem and I am able to connect from a 1/8 stereo microphone jack on my camera to the RCA out of the soundboard now with no problem or noise. ... I would recommend this product as well as purchasing any products from B & H Photo-Video-Audio in New York.

With VCA down it takes out the ground wonderfully, an active powered approach to ground level noise. Wonderful product and beats the passive unpowered boxes.

Works but  induces noise

The Clean Box provided the required step up in voltage and impedance to match my consumer HT AVR to a Behringer ep4000 to drive two Fi Audio IB318 woofers. However, to get adequate volume the Art's introduced unacceptable noise into the circuit.

Wanting to isolate a balanced run so can I input balanced, route unbalanced output back into unbalanced input and get balanced output?
Asked by: Dave
You may take a balanced line into ch 1 bal line in, out of line 1 Unbal line out into line in 2 and then back out line 2 bal out, so yes.Im not sure how it will sound tho, as thats a lot of conversions and impedance changes- better to use an isolation transformer, or buy an in line isolation transformer/barrel instead.

Will this convert a mono XLR out from a mixer's main output(+4) to a dual mono signal over 1/8&quot; TRS to a suitable level for a camcorder?
Asked by: Mark
The ART Cleanbox Pro is neither ideal, nor made for that use. You would want to use something more like B&amp;H # SES43DBMZ2XJ or B&amp;H # KOCMX2V2 for that application.

Will this work with the output of a Vocaster 2 (1/4&quot;) to Mic input of a ATEM Mini Pro (3.5&quot;)? If so what connectors do I need?
Asked by: Aaron
The ART CLEANBoxPro does not convert Line level to Mic level, so it would not be suitable for connecting the monitor outputs of an interface to the mic input of a switcher. However, its 3.5mm output could be used in conjunction with an attenuator cable such as BH #WHH4NL3.5 for this purpose.

question

With a balanced input will it output both balanced and unbalanced?
Asked by: luis
No, there are two separate one way paths. Bal to unbal and unbal to bal.
