Contacta V-Series V22a PRO Hearing Loop Driver
Description
V-Series V22a PRO Hearing Loop Driver. 2 X 90° phase shifted (DSP controlled) Class-D amplifier 8A RMS @ >22.6VRMS
DSP controlled auto gain and high frequency compensation for meta loss.
Audio Time delay, Switchable AGC, Loop diagnostics, Full colour LCD display. 1 RU full rack space.
Our highly efficient and powerful V22a PRO is a constant current hearing loop driver with dual output for phased array loop layouts. It is designed for medium-sized facilities and venues.
It has a Class-D amplifier output stage and an audio subsystem built around advanced digital systems including an ARM Cortex processor and dual DSPs. Combined with a powerful CPU to ensure peak performance, the V22a PRO provides self-monitoring and email alerts, remote setup over local area networks, guided hearing loop setup to make installation simple, and excellent speech and music reproduction.
Applications
