Radial Engineering RAD-PROAV2 Passive Stereo DI with RCA 3.5 mm XLR and 0.25 in. Inputs

The Radial ProAV1 and ProAV2 are passive direct boxes specifically developed with the audio-video integrator in mind. The ProAV1 features a variety of stereo inputs that are merged via a resistive mixer to mono, greatly simplifying signal management and the ProAV2 has full two-channel stereo functionality. To eliminate the need for various adapter, 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( s) for professional systems. Front panel connectors can also be used as thru-puts to allow multiple patch points. 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. The ProAV1 is ideal for events that interlace audio with video where music sources can include iPods, CD players and video decks. The ProAV2 stereo version trades some of the connectivity features for it's full dual-channel stereo operation. Both ProAV1 and ProAV2 will be welcome additions to the AV technician's tool box.
