Inputs are available via 1/4″, RCA, 3.5mm stereo, and line-level XLR connections, giving you the ability to easily connect to smartphones, tablets, laptops, CD players, or even a +4dB line level output from a console or recording interface.

Radial Engineering ProAV1 – Audio/Video Passive Direct Box

The ProAV1 Passive Direct Box is ideal for events that interlace audio with video where music sources can include iPods, CD players and video decks.

To eliminate the need for various adaptor, a “Swiss Army” array of connections are provided, including 1/4″ for instruments, RCA and 1/8″ connectors for consumer electronics and computers and a +4dB XLR input for professional systems. The front panel connectors can also be used as thru-puts to allow multiple patch points.

Custom wound transformers are employed that are able to withstand exceptionally hot levels while maintaining linearity from 20Hz to 18.5kHz. The resulting smooth Bessel curve is warm and natural, making the AV1 particularly adept at handling digital sources that can sound harsh. Transformer isolation adds the benefit of eliminating ground loops that cause audio hum and buzz and video hum bars or snow.

Ultra-quiet passive design requires no external power source
Eliminates ground loops that can cause hum and buzz
Handles huge transients without distortion

Consumer Audio to PA System
The ProAV1 is perfect for interfacing consumer audio electronics with pro PA and recording equipment. The dual phone, RCA and 3.5mm inputs on the ProAV1 sum the left and right stereo channels to a mono output.

Standard DI For Instruments
The ProAV1 Passive Direct Box works just like standard direct boxes for passive and active musical instruments like guitars, basses, and keyboards. You can thru-put the signal to an on-stage amp while transformer isolation keeps things quiet.
