PDA200E WALL MOUNTING INDUCTION LOOP AMPLIFIER Ideal for meeting rooms, lecture theatres, churches, schools, TV lounges, shops and other small to medium sized applications Provides max. square room coverage of 120m2 (11m x 11m) or max. rectangular room coverage of 250m2 (10m x 25m) Straightforward internal screw connectors Wall mountable for permanent installation – ideal for schools and colleges where rooms are often left unsupervised Internal tamper-resistant drive, level and tone controls One balanced/unbalanced microphone input One balanced/unbalanced line level input Alert tone switch input for doorbells, fire alarms, security systems, etc 100V line input for PA system connection Fully automatic compressor-limiter Full 2Ω drive capability for increased coverage at higher frequencies Compatible with SigNET’s unique ‘outreach plate’ input extension system Available in a variety of kit formats to suit a host of typical loop installations Fully compliant with EN60118-4 (formerly BS6083) and BS7594:1993 The PDA200E has revolutionised the induction loop marketplace by bringing the ability to understand, install and appreciate the technology involved to a whole new client base. Straightforward internal screw connectors and preset controls mean no specialist audio experience or audio connectors are required. By following the simple set-up procedure, no further adjustments are necessary, allowing a top quality assistive listening system for the hard of hearing to be set-up in its entirety by new and experienced installers alike. No less than four easy-to-access inputs are provided: Balanced/unbalanced mic (with phantom power for use with electret mics). Balanced/unbalanced line (for the connection of TV and other audio feeds). Alert tone switch (a tone generator for use with doorbells, fire alarms, etc). 100V line (for the connection of PA system audio feeds). The amplifier’s state-of-the-art current drive audio processing circuitry includes an automatic compressor/limiter which maintains the loop signal within a small dynamic range to improve intelligibility. Manual adjustments can also be made using the amplifier’s internal tamperresistant drive, level and tone controls, allowing the system to be tailored to suit the exact requirements of any room. For ease of specification and installation the PDA200E is available on its own or in the following kits formats:AKM1 Meeting/seminar room kit AKR1 Waiting room kit AKT1 TV/Music lounge kit AKW1 Place of worship kit 1 AKW2 Place of worship kit 2 AKH1 Heath and fitness club kit AKL1 Lecture room kit AKU1 Retail unit kit (the exact contents of each kit are listed overleaf) Optional 100V line input from PA system APM Omni-directional microphone Belden twin pair screened audio cable A typical PDA200E meeting/seminar room installation using items supplied in our AKM1 kit Loop Cable (not supplied see tech specs for recommended type) PDA200E POWER REQUIREMENTS INPUTS Three 5mm screw connector inputs are available - mic., line & 100V. If more than one is used, the signals are mixed MICROPHONE Input impedance 600Ω balanced/unbalanced Sensitivity 2-5mV (-46db to -50db) Phantom 12V LINE Input impedance >10kΩ balanced/unbalanced Sensitivity 0dbv (300mV rms to 1.5V rms) 100V LINE Input impedance 200kΩ Sensitivity +40dbv ALERT Closing a volt-free switch across this input generates a 2kHz tone through the loop. Should additional inputs be required, the PDA200E is compatible with SigNET’s outreach plate input extension system. This allows up to ten extra mic or line level inputs to be daisy-chained to the PDA200E. See our separate datasheet for details.
