Radial ProAV1™ and ProAV2™ Specifications

The Radial ProAV1 and ProAV2 are passive direct boxes designed to handle the extreme dynamics and frequency range that is now common with digital sources. Linear across the audio range, these exhibit low distortion at all frequencies, amazing signal handling and very little phase shift. The result is a clean, natural sounding rendition that is both noise-free and dependable.
