The PDA103L, PDA103R, and PDA103S are audio frequency induction loop systems (AFILS) designed for small rooms when the area is up to 50 square metres.
Each amplifier has has an 3.5mm jack socket for the unbalanced, -60dBV microphone input for use with the supplied AMT tie clip/desktop microphone. A stereo 3.5mm jack socket, provides a -27dBV unbalanced input for connecting an external audio source at 'line level' and a balanced 4-way connection block offers an input at -10dBu for linking with up to ten outreach audio plates.
The IP40 rated amplifiers may be wall-mounted Rotary controls for the input channels are located on the front panel along with a level control to adjust the strength of the magnetic field generated and a metal compensation control to help combat any frequency response issues normally caused when excessive metal absorbs the magnetic field. There are four LEDs which are useful indicators of the system's performance. The first is a red LED that illuminates when the 10dB auto gain control (AGC) circuitry is performing correctly at its preset 20:1 ratio. The second red LED illuminates when any of the input channels reach the peak input level. The third red LED illuminates to signify any loop faults such as an unintentional connection to an input ground. The final LED is green and is lit when the amplifier is receiving power.
