Dynamic range >36dBMetal Loss CorrectionCorrects system frequency response issues due to metal structures in a building. Gain constant at 1kHz, adjustable gain slope from 0 to 4dB per octave in 0.25dB increments.Custom dual slope MLC allows different slopes and knee frequency to be set via the menu (network models only). This does not compensate for signal loss from metal structures which can be significant.Phase ShiftUser selectable (network models only) at 0° or 90° between outputs Specifications: Perimeter Loops – Area Coverage (maximum)Room aspect ratio1:12:13:1Maximum area m2120150200For any Induction Loop System, area coverage is dependent on several factors. Please check these assumptions and contact Ampetronic for advice if required:Loop must be 1-2m above or below the receiver heightThere should be no metal structures in the plane of the loopSufficient voltage to drive the loop – check the cable table belowMaximum Cable LengthThe ILD122 is designed for SINGLE TURN loops for optimum audio quality.Loops with DC resistance from 0.2 to 1.8ΩImpedance up to a maximum of 2.0ΩMaximum cable length is dependent on cable type and on the application:Cable typeMaximum Cable Length (m) Normal Use*Transient Speech*1.0mm2 copper76872.5mm2 copper1031314.0mm2 copper1081401.8mm2 flat copper tape133155* Short term speech (e.g. service counter, airport PA system) can cope with limited clipping at high frequencies – Ampetronic recommends delivery of full current up to 1.2kHz for these applications.Longer term usage or signals with music or high quality audio must deliver full current to at least 1.6kHz to prevent fatigue and give acceptable intelligibility. Many commercially available systems do not deliver sufficient voltage to reproduce critical high frequencies – ask us for more details.ILD122 SpecificationsINPUTSPower35 W 230 V AC nominal, 45-65 Hz [120 V option available]Power switch and LED indicator on front panelMicrophone inputXLR balanced microphone input for 200-600 Ω microphones;15 dB user selectable gain boost; 15 V DC phantom power (selectable); sensitivity – 70 dBu; front panel recessed gain controlLine input6.4 mm jack socket balanced line input; sensitivity – 30 dBu; overload protected; front panel recessed gain controlLink I/O6.4 mm jack insert point for connection of SP5 phase shifter0 dBu signal can be used for recording OUTPUTSDrive voltage8.5 Vrms (12V peak) at maximum output currentDrive current• 3.5 Arms (5 Apk) continuous 1 kHz sine wave• Short term peaks >7 Apk• Front panel recessed control• Drive current indicated on 4-LED display in 3 dB incrementsLoop connectorWieland ST17/2 (supplied)Loop MonitorProvides access to actual audio signal in loop via a 3.5 mm stereo headphone connector on front panel THERMAL HEAT CHART Idle1/6 peak Output Current (Speech)1/3 peak Output Current (Pink noise)Full PowerDriverChannelsCurrent (ARMS)Load Resistance (Ohms)AC In (W)BTUAC In (W)BTUAC In (W)BTUAC In (W)BTUILD1000G19.21.5196550147115296320659ILD50016.41.515514614580227168366ILD30014.91.08271857329166142ILD12213.51.08271549247254142ILD100DC13.40.51.023619123720.450 AUDIO SYSTEMFreq. response80 Hz to 6.5 kHzDistortionTHD NAutomatic Gain ControlThe AGC is optimised for speech.
