AMPETRONIC INDUCTION LOOP AMPLIFIERS - CLD1 Series - Counters, small rooms and vehicles

Designed for counter systems and small-area perimeter loop systems, such as ticket counters or small interview rooms, taxis and cars. the CLD1 is housed in a small metal case with flanges with fixing holes for mounting to surfaces or under counters. When used as a perimeter loop driver, maximum coverage is 35 square metres. When used with the optional counter-loop kit, it will project a field to the requirements of IEC60118-4 approximately one metre from the loop.

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 ‘excellent’ 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.

CLD1

There are two inputs using 3.5mm jack sockets, one for a microphone, the other switchable microphone or line, each providing DC powering for electret capsules. Screwdriver controls are provided for sensitivity of the two inputs, loop-current and metal-loss correction. LEDS indicate input signal, loop-current and power.

Frequency response: 80-6300Hz. AGC: Optimised for speech, dynamic range greater than 36dB. Output current: 2.4A RMS, 3.4A peak. Power source: 12V DC, 1A maximum, or 230V AC 45-65Hz using the AC power adapter. Dimensions: 128 x 74 x 35 mm.

Included accessories: Handbook and installation instructions. ‘Loop system present’ sign, AC power adapter. For kits including microphones and pre-formed loops please see CLD1-CT, -CB, -CD below.

CLD1 AC

This provides the same performance and functionality as the CLD1, but is powered directly from AC power, via a two-pole, IEC320 figure-8 connector. Power source: 230-240V AC. Dimensions: 178 x 74 x 35mm.

Included accessories: Handbook and installation instructions. ‘Loop system present’ sign. AC power lead. For kits including microphones and pre-formed loops please see CLD1 AC-CT, -CB, -CD, -CX below.

CLD1-CT, CLD1 AC-CT

Included accessories: As the CLD1 and CLD1 AC respectively, plus a tie-clip style electret microphone with three metre lead and a GE00001 loop-coil kit which should be unfolded and mounted vertically inside the front panel of the counter, using the adhesive clips provided.

CLD1-CB, CLD1 AC-CB

Included accessories: As the CLD1 and CLD1 AC, respectively, plus an electret boundary-layer microphone and a GE00001 loop-coil kit which should be unfolded and mounted vertically inside the front panel of the counter, using the adhesive clips provided.

CLD1-CD, CLD1 AC-CD

Included accessories: As the CLD1 and CLD1 AC respectively, plus a desk-top electret microphone and a GE00001 loop-coil kit which should be unfolded and mounted vertically inside the front panel of the counter, using the adhesive clips provided.

CLD1 AC-CX

Included accessories: As the CLD1 AC, plus a GE00001 loop-coil kit which should be unfolded and mounted vertically inside the front panel of the counter, using the adhesive clips provided.

ILD20 Loop Amplifier

This has now been replaced by the CLD1 AC.

Warranty

Ampetronic offer a full five-year warranty on all products manufactured by them effective from date of shipment, provided the equipment has been used exclusively for the intended purpose and has not been modified, altered, used in an inappropriate manner or repaired by a non-authorised person. There are very few product exceptions (see www.ampetronic.com/info/terms.php for further details on products covered) to this warranty. Note: Repairs found to contravene these conditions may be subject to a further charge plus shipping and handling fees.
