Descrizione

ProAV2 by Radial Engineering is a Stereo Passive Direct Box designed specifically for AV operators and technicians, featuring a variety of input connectors that allow easy interfacing with a wide range of audio equipment such as: standard 1/4'' Jack, RCA, 3.5'' TRS, balanced outputs with XLR connectors (MIC level 600 Ohm), plus Ground Lift and -15db attenuation Pad.

Key Features

    
• Versatile Stereo Direct Box ideal for multimedia applications
    
• Ultra-quiet, easy-to-use passive circuitry
    
• Transformer isolation eliminates hum and background noise
    
• Handles high-level transients without distortion

Radial ProAV2 is a passive DI Box designed to handle the wide dynamics and frequencies of modern digital sources. It features a linear response across the entire audio range, with low distortion at all frequencies, versatile signal management, and very low phase shift. The result is a clean, neutral, noise-free sound.

Practical Applications of ProAV2

Connect any device to a PA System

ProAV2 is an indispensable device for both live sound engineers and audio-video technicians, thanks to its ability to perfectly interface most devices with a professional audio system. It features a stereo 3.5mm input jack and dual 1/4" and RCA connectors that eliminate the need for adapters, and ultra-quiet audio performance due to transformer isolation to eliminate hum and noise from ground loops. ProAV2 maintains stereo separation and offers a linear frequency response from 20Hz to 20kHz, with mic-level balanced XLR outputs allowing signals to be sent on stage via a multi-channel audio snake, or to two channels of a mixing console.

ProAV2: Stereo In – Stereo Out

ProAV2 has a True stereo (Dual Mono) architecture, making it ideal for devices such as laptops and DVD players. It is also possible to connect phones quickly and without adapters, using its RCA and 3.5mm jack connectors.
