2x Ampetronix ild300 induction loop driver units
From canford / ampletronic below
Suitable for applications requiring a larger coverage area including conference facilities, theatres, sports halls, educational environments, larger meeting rooms, cinemas, courts and lecture halls, these loop drivers will cover up to 1300 square metres. They are AC powered and may be wall or rack-mounted.
Ampetronic systems are designed for ‘fit-and-forget’ reliability. Their frequency response ensures intelligibility for the hearing aid user, essential for extended periods of listening, or where there is any musical output in the signal. A compressor and automatic gain-control system, combined with wide-band audio circuitry, produces ‘excellen’t reproduction of music and speech. Normal speech dynamics are retained to maximise expression, while the total dynamic range is automatically adjusted to a level suitable for hearing-aid users. The systems can also be used by people with no hearing aid, by using separate loop receivers, such as the Ampetronic ILR3, for those with partial hearing impairment, or in visitor guidance applications and teaching in noisy environments.
The loop drivers are designed to be used with simple, single-turn loop installations. With appropriate loop array designs, the loop drivers can also be used in areas of high metal losses, and for adjacent rooms or confidential environments where interference or spill-over must be avoided
This model is designed to cover loop areas up to square areas of 250 square metres, or rectangular areas of over 400 square metres, depending on loop-aspect ratio.
The ILD300 is built in a half rack-width case. On the rear it has a single balanced microphone input using an XLR connector, with +15V phantom power available. A balanced line input is provided using a 6.35mm 3-pole jack socket, and an input / output using a 6.35mm three-pole jack for recording, slave and insert purposes. A mini-DIN connector provides an ancillary DC outlet, +/- 15V DC, for powering accessories such as Ampetronic’s pre-amplifiers, See Ampetronic Adapters and Pre-amplifiers. A preset control sets metal-loss correction. The IEC power inlet has an associated fuse, the loop output uses a detachable connector.
The front has recessed preset controls for sensitivity of the microphone and line inputs, drive current. Two four-LED displays indicate compression and loop current. LEDs indicate overload, over heat and loop error conditions. A 3.5mm stereo jack socket provides access to the actual audio signal in the loop for use with headphones. The power switch has an associated LED. It may be used free-standing or mounted in a rack or on a wall using accessory brackets.
Frequency response: 80-6500Hz. AGC: Optimised for speech, dynamic range greater than 36dB. Output current: 7A sine wave, 1kHz; more than 10A peak. Power source: 230V AC nominal, 45-65Hz, 35W. Dimensions: 215 x 210 x 44 mm. Weight: 2.25kg.
Included accessories: Handbook and installation instructions. Power cable. ‘Loop system present’ sign, 197mm x 252mm. Mating connector for loop output.
Optional accessories: Wall mount brackets WML-1U, rack mount brackets RM-1U, see below. Note that the ILD 300 is one half-rack width so will need a BPL-1U blanking plate if only one ILD 300 is mounted in the RM-1U. Also see Ampetronic Adapters and Pre-amplifiers.
