CHIL/PRO
induction loop amplifiers are ideal for use in large prestigious
applications such as theatres, churches, cinemas, conference
halls, etc., where first class sound and reliability are
a must.
Each amplifier has three inputs - Mic., Mic./Line and
‘Outreach'. The Mic. and Mic./Line inputs will accept
standard three pin XLR connectors. The four-way ‘Outreach'
input offers full compatibility with our unique Outreach
Plate audio input extension system. This system allows
the connection of up to ten additional microphone or line
inputs via a range of specially designed single gang audio
connector plates.
The pre-amplification stage of each amplifier utilises
an advanced signal processing system that allows tight
control over the audio signal without any degradation
of output quality. A metal compensation control is also
provided to help offset the frequency response problems
caused by the excessive metal content of some rooms.
Other features include three level controls (one for
each input), a loop drive control, an output current meter
and a ‘compression' activity display giving visible
indication of the amplifier's compressor.

TYPICAL PDA PRO-RANGET PLACE OF WORSHIP APPLICATION
Almost any single core tri-rated cable can be used for
the induction loop provided it is of the appropriate DC
resistance (ideally 0.5 to 1 Ohm). The graph on the right
shows the recommended CSA for different lengths of loop
cable. Simply work out the length of the loop required
and choose a cable size that falls into the non-shaded
area of the graph.
For example, to cover a room 30m x 20m (600m2) the loop
cable would need to be 100m long (2 sides @ 30m and 2
sides @ 20m). The recommended cable CSA for a loop this
length is between 2mm2 and 4mm2. Therefore, a CHIL/1000/2
(which can cover areas up to 900m2) using 2.5mm2 cable
would be sufficient.
