PDA103S Kit Components
1 AFILS sticker:
Position the sticker where it can be clearly seen by hearing
aid users.
2
APL dual phono line
level ‘outreach’ plate
c/w APS SCART lead &
Belden connection cable:
Surface-mount the APL plate onto a standard 25mm UK
back box - a 6m length of Belden cable is provided for
connecting the APL to the amplifier. The APS SCART lead
(supplied), should be connected to the audio source
(normally a TV) and the APL plate.
3 Amplifier location:
The amplifier should be surface-mounted and sited as close
as possible to the equipment to which it is connected.
4 Loop cable:
Run the loop cable horizontally around the perimeter of
the room. For best results, tuck the cable under the edge
of the carpet or fixed to skirting boards or the ceiling.
If installing a floor loop, ensure the loop cable is protected
from being crushed in walkways or by furniture.

PDA103 Installation Instructions Approved Document No. DAU0000103 Rev 2
Note: As an alternative to using the APL plate, the amplifier supplied with the PDA103S kit
has a TOS-link digital connector and most modern televisions can be directly connected to
the amplifier using a TOS-link cable (not supplied).
Inputs & Controls
1
Mic input:
3.5mm mono jack input supplied with 12V phantom power
for use with electret microphones. Note that dynamic
microphones are NOT compatible with this input.
Mic control: Adjusts the sensitivity of microphone level input.
2
Line input: 3.5mm stereo jack input for connecting an audio (line) source.
Line control: Adjusts the sensitivity of the audio line level input.
3
Digital input: TOS-link digital input (PDA103S kit only).
Digital control: Adjusts the sensitivity of the TOS-link input (PDA103S kit only).
4
Outreach input: 4-way input for the outreach plate audio input system.
Outreach control: Adjusts the sensitivity of the outreach input.
5 DC in:
2.5mm DC power supply connector. The amplifier operates at
20Vd.c. Only the plug-top power supply (supplied) should be
connected to the amplifier.
Indicators
9 Limit: Illuminates red to confirm the AGC circuitry is functioning.
10 Peak: Illuminates red in line with peaks in the input signal(s).
11 Loop Fault:
Illuminates steady red when the induction loop is unintentionally
connected to an input ground. To rectify, turn off the mains power
supply and check for loop wiring faults.
Product Safety Note: When the DC power supply is connected to the
amplifier (with the mains on), this indicator may light and the
amplifier will shutdown. If this happens, turn off the mains power
switch and wait for 10 seconds before switching mains power back on.
12 Power On: Illuminates green when the amplifier is receiving power.
Outputs & Controls
6 Loop output: 2-way induction loop connection.
7
Metal Compensation
control:
In applications with high metal content, this control can be
used to help combat the frequency response problems caused
by metal ‘absorbing’ the magnetic field.
8 Level control:
Adjusts the strength of the magnetic field generated by the
induction loop.
