Description

V-Series V34 PRO Hearing Loop Driver. Single Channel Class D Amplifier 12ARMS @ >34VRMS

DSP controlled auto gain and high frequency compensation for metal loss.

Audio Time delay, Switchable AGC, Loop diagnostics, Full colour LCD display. 1 RU full rack space.

Our highly efficient and powerful V34 PRO is a constant current hearing loop driver with a single output for perimeter loops. It is designed for large 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 V34 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

Suitable for large facilities and venues such as:

  • Theatres
  • Concert halls
  • Places of worship
  • Sports arenas
  • Conference facilities
Standards
  • Induction loop performance compliant with BS EN60118-4 (when correctly installed)
Features
  • Inbuilt guided hearing loop setup utilising an integral test signal generator
  • Intelligent self-monitoring system supplies status emails on changes to driver functions
  • Dual-DSP controlled automatic gain control and high frequency compensation for metal loss
  • Class-D amplifier output stage capable of delivering 12ARMS @ >34VRMS
  • Highly-rated custom heat-sinks and active cooling
  • Integrated universal switch mode power supplies provide ultra-efficient power utilisation (up to 90% efficient)
  • Constant current output stage
  • Adjustable audio time delay for audio syncing across large distances
  • Intuitive and sleek user interface on a full colour, high resolution LCD
  • Adjust both drive and loop output levels using an embedded LAN service, minimising installation time
  • Settings/profiles saved to a USB storage device
  • Continuous self-testing
  • Integrated protection circuits with temperature, voltage, short circuit and DC detection
  • Full width 1U 19” rack mount
