Contacta V-Series V22 Hearing Loop Driver
Description
V-Series V22 Hearing Loop Driver. Single Channel Class D Amplifier 12ARMS @ >22VRMS
DSP controlled auto gain and high frequency compensation for meta loss.
Audio Time delay, Switchable AGC, Loop diagnostics, LCD display. 1 RU full rack space.
The V22 is a powerful constant current, single output hearing loop driver. It is suitable for hearing loop systems in medium to large venues for perimeter and figure-eight loop layouts. The Class-D output stage deliver enough current to handle tough loop loads.
The audio subsystem is built around an advanced DSP Core with microprocessor control. This modern driver delivers an optimal combination of efficient performance and power. It provides a high-spec and feature-rich interface which is easily controlled from the LCD display.
The built-in Line Output allows for additional V22 drivers to be chained from the first. Note: The Line Output is not phased and cannot be used to create phased pairs of V22s.
