Radial Engineering ProAV1 Multi-media Passive Direct Box

These innovative DIs feature a 'Swiss army knife' compliment of connectivity options including standard 1/4" jacks for instruments, RCAs jacks for hi-fi gear, and 3.5mm (1/8") mini TRS making them ideal for interfacing computers and other -10dB consumer electronic devices.

The motor is a custom wound, high performance transformer that yields a linear response from 20Hz to 18kHz that is both warm and true. This is augmented with a mu-metal can that encapsulates the transformer to reduce potential magnetic field contamination from outside sources such as power transformers, dimmers and video screens. Anyone that has placed a speaker next to a video monitor knows how magnetic interference can disturb electron flow. IN Audio, the problem can be heard!

The forgiving nature makes the ProAV1 a perfect mats for high output devices that can easily overload typical direct boxes. Furthermore because both units provide transformer isolation, problems such as hum & buzz caused by ground loops are eliminated.

The ProAV1 is a single channel DI with stereo inputs and an auto merge function that mixes left and right signals to mono mic level at the XLR output. It is augmented with a +4dB balanced XLR input for interfacing pro gear such as VTRs. The ProAV2 is a straight ahead stereo DI that converts -10dB to mic level. For permanent installations, both units can be mounted in a podium or under a table top using the Radial J-Clamp or may be 19" rack mounted using the Radial J-Rak.
