Hello and welcome to this buy-it-now sale for this Ampetronic Induction Loop Driver ILD9

The Ampetronic ILD9 Induction Loop Driver is designed to cover loop areas up to 500m². Several units can be connected together in Master Slave configuration for driving single turn loops covering much larger areas such as Cathedrals, sports halls and theatres. It can also be used for large conference rooms and other areas where specialised requirements apply. In these environments, the equipment can be used to drive phased arrays for low-spill operation. These specialised loop layouts can be designed by Ampetronic Ltd. who also supply the precision phase shifter needed for this work.

TECHNICAL SPECIFICATION

Line Input:

6.4mm Jack socket, fully balanced (unbalanced with mono plug).

Sensitivity: -40dBu) to +10dBu.

Common mode rejection > than 50dB below 500Hz. Overload protected.

Slave I/O:

Insert point for connection of Ampetronic Phase Shifter, Preamplifiers etc.

Can be used as output for recording purposes.

Signal level 1V RMS (+2.7dBu).

Metal Loss Corrector:

This control permits correction of the system frequency response when losses occur due to metal in the building. Loss adjustment is adjustable from 0 to 3dB per octave, using 1kHz as constant gain frequency. This does not compenstae for the power loss caused by the metal.

Loop Current:

9.6A peak signal current into a SINGLE TURN loop. Metering via front panel LEDs. These LEDs indicate the peak current, with intervals of 3dB.

Loop Voltage:

Greater than 36V peak, to enable good frequency response for larger, inductive loops. Patented circuitry prevents clipping to ensure EMC complience.

Loop Resistance:

Must be less than 2 Ohms but greater than 0.4 Ohms.

Compression:

Compression range 30dB before overload. Front panel indication of compression level.

Efficiency: less than 0.25dB output change for a 25dB input change.

Attack and Decay time constants optimised for speech.

Frequency Response:

80Hz - 10KHz ±1.5dB at low level, measured as loop current. High frequency high signal level response is a dynamic variable and is a function of loop size, loop current and signal content to ensure that no RFI generation takes place. Internal time constants are very short.

Pre-Amp Power:

± 15V DC regulated output, up to 0.3A

AC Power Input:

230V AC nominal, 45-65 Hz.

160VA. Fuse T 1.6AF

Dimensions:

Length: 432 mm.

Depth: 220 mm. 

Height: 88 mm. (2U)

Condition:
