Product Overview
Our highly eicient and compact V7, V12a and V14 hearing loop drivers
are suitable for smaller facilities and venues.
The V7 and V14 are constant current hearing loop drivers which power
hearing loops utilising a single output. The V12a 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:
Voltage capability of the driver (V7: 7.5Vrms, V12a: 12Vrms,
V14: 14Vrms) divided by the required current.
This achieves 400mA/m eld strength at 1kHz.

Example of finding suitable cable length using V12a:
A loop requiring 110m of cable needs 3A at 1kHz to achieve the
required eld strength.
If there are two cables in stock 0.5mm round and 1.5mm round, by
looking at the above table we can see that the maximum length at 3A
for the 0.5mm cable is 68m.
Using this cable will cause the driver output to clip at 1.6kHz when
driven at 3A. Using the 1.5mm cable will allow the 3A to be driven at
1.6kHz without clipping.
