Product Overview
Our highly eicient and compact V7, V15 and V15a hearing loop drivers
are suitable for smaller facilities and venues.
The V7 and V15 are constant current hearing loop drivers which power
hearing loops utilising a single output. The V15a is a constant current
dual output hearing loop driver with integral phase shifter for phased
array conguration.
These hearing loop drivers have Class-D amplier output stages and
an audio subsystem built around an advanced DSP core. Combined
with a powerful CPU that ensures peak performance, they use cutting
edge technology proven in the pro audio world to achieve life-like
speech and rst-class music reproduction.
Note: For large area hearing loop installation instructions, consult the
Large Area Hearing Loop Installation Guide.

Cable & Equipment: A length of loop cable determined by the loop
design is also required. Hearing loop drivers also require ancillary
equipment for audio feeds, such as a microphone or sound system.

Suitable Cable Lengths
The tables in this section show the approximate maximum cable
lengths for diering maximum required currents.
Loop impedance (at 1.6kHz) should be less than the voltage capability
of the driver (V7: 7.5Vrms, V15: 15Vrms, V15a: 15Vrms) divided by the
required current.
This achieves 400mA/m eld strength at 1kHz.
