PDA200E Wall Mounted Hearing Loop Amplifier 100V-Line

Product Features

• A new version of 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 over heating
• 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

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.
