A new version of our popular PDA200E wall-mounting hearing loop amplifier supplied in a small, compact metal enclosure measuring just 228mm wide, 155mm high and 42mm deep – around half the size and weight of its predecessor. The PDA200E is a wall-mounted hearing loop amplifier that can drive a perimeter loop of up to 200m2 (14m x 14m) in free spaces with low metal content.
Product Features
A new version of the popular PDA200E wall-mounting hearing loop amplifier
Supplied in a small, compact metal enclosure measuring just 228mm wide, 155mm high and 42mm deep – around half the size and weight of its predecessor
Now features a 100V line input (to accept feeds from PA/VA) systems and an energy-efficient Class D digital output stage
Can drive a perimeter loop of up to 200m2 (14m x 14m) in free space/areas with low metal content
Two balanced/unbalanced line-level inputs
One microphone input with 12V phantom power
Outreach connector allows up to 10 of our audio input utility plates to be added
Automatic compressor-limiter maintains the loop signal for improved intelligibility
Each input has a separate internal tamper-resistant control that can be manually adjusted
Compression, output (Peak Current 3, 2, 1) and power on (Power) front panel indicators
Short circuit protection
Internal temperature safety cut-out to stop overheating
Wall-mounted metal enclosure for a permanent robust installation
Exceeds the requirements of PD IEC TR 63079 & EN60118-4 when correctly installed
Also available in a variety of ‘AK’ Range kits for use in meeting rooms, lecture theatres, places of worship, health and fitness suites, elevators and more
In areas over 5m wide with high metal content consider using a phased array loop system instead
Power

Hearing Loop Cable
Max. Area of Coverage: 200m2 (14m x 14m) using 1mm2 cable – low metal content
Hearing Loop Impedance: 0.5 to 1Ω @ 1kHz
Sensitivity Level Controls (all rotary pot controls are screwdriver adjustable)
LINE: 1 & 2 Used to set the signal levels of the two line level inputs.
MIC: Used to set the signal level of the microphone input.
METAL C: Used to compensate for the loss of high frequencies that occur when significant amounts of metal are present. Turning this control clockwise boosts the range by +3dB per octave.
DRIVE: Used to adjust the strength of the magnetic field generated by the hearing loop by increasing/decreasing the electrical current driven into the loop.
100V: Used to set the 100V line level of the PA/evacuation system input.
Front Panel Indicators
Limit: Red LED – Indicates the signal level after adjustment. This
indicator should not be permanently lit after set up.
High/Medium/Low: Red/Yellow/Green LEDs – Provides a scale indicating the electrical current being driven into the loop. The red High indicator should only light with peaks in the input signal.
Loop Fault
Yellow LED – Lights when the hearing loop is cut or the loop impedance is not within range. To rectify, turn off the AC mains and check for loop wiring faults before re-applying power.
Power: Green LED – Lights when the amplifier is receiving power.
