The PDA500 and PDA1000 are professional 19” rack-mount induction loop
amplifiers offering outstanding sound quality. They are ideal for use in
large prestigious applications such as theatres, cathedrals, large
conference halls, etc., where first class sound and unrivalled reliability are
a must.
Each amplifier includes one balanced/unbalanced microphone input (with
optional phantom power) and one balanced/unbalanced line level input.
Both inputs accept standard 3pin XLR connectors.
The pre-amplification stage of both amplifiers utilises an advanced signal
processing system that allows tight control over the signal without any
degradation of output quality. A selection of internal controls are also
provided, allowing the processor to be further adjusted by experienced
installers to suit a specific application.
The PDA500 and 1000 are supplied in 1U and 2U cases respectively and
both feature an input peak LED, recessed level and drive controls and an
output current meter to monitor loop activity. Their flexibility is further
enhanced by their compatibility with SigNET’s unique ‘outreach plate’
input extension system.

One output drive control, giving a loop current adjustable between 40mA & 2.6A
(PDA500) and 100mA & 5A (PDA1000)
Engineer controls
Two internally adjustable jumper links are provided (accessible to suitably skilled and
technically competent personnel only). Their functions are described below:Link 1 allows the processor to be set up for compression or compander mode operation.
(Compression is the default setting and is recommended for systems where the main input is from
a mixing desk or theatre stage. Compander mode is recommended for systems using multiple
microphones where there is little or no external signal processing).
Link 2 allows the amplifier’s ‘duck’ facility to be switched on or off.
(When switched on, the MICROPHONE input is attenuated by 10dB for every 1dB of the LINE input
above a threshold level. This is useful for theatre-based applications as it helps prevent echo
occurring when an audience response microphone is used in conjunction with a stage/front of
house signal feed to the loop amplifier’s line level input stage. The default setting is ‘Duck’ off).
