Hearing Loop Setup Mechanical / Mounting Technical Specification Standards Contacta has a policy of continuous product development, therefore small specification changes may not be reflected in this manual. Images, labels, packaging, accessories and product colours are subject to change without notice.
Product Overview The ID-6 hearing loop driver is a cost-effective solution designed for seamless integration into various OEM equipment requiring a hearing loop output. With a compact design, flexible mounting options and wide operating power supply range, the driver is versatile for use in applications such as digital signage, retail counters, help points, intercoms, and lifts.
Components ID-6 / ID-6B Hearing Loop Driver 2. Signage [IL-SN01 / IL-SN02] 3. 4 x Universal Wall Plugs 4. 4 x Fixing Screws Cable & Equipment: A length of loop cable determined by the loop design is also required. Hearing loop drivers also require ancillary...

75V/100V Line Level Sources should be connected between pin 1 (Com) and pin 3 (75V). B) Mute Mute signal for fast disable/enable of outputs: HIGH (Greater than 6V) = outputs OFF (high-Z), LOW = outputs ON. The ID-6/6B is unmuted if this input is not used (unconnected).

C) Status Indications INPUT OK: This LED lights when the input signal is at the minimum level necessary to drive the ID-6 / 6B. If the driver is operating on higher supply voltages with some loops it may be possible to increase the input gain on the LINE IN input beyond the point where the INPUT OK LED lights.

Warning: This output is bridge-tied. Grounding either output may damage the device. E) DC IN The ID-6 can operate from direct current (DC) power supply voltages from 12V to 24V (18V to 24V for battery backup). Warning: Before applying power be sure to check the polarity.
Suitable Cable Lengths The tables in this section show the approximate maximum cable lengths for differing maximum required currents. Examples shown at 12V, 14V and 24V supply voltages. 12V PSU Single-Turn Hearing Loop (Metric) Double Turn Hearing Loop (Metric) 12V Power Supply (Metric) 12V Power Supply (Metric) 2.0A 3.0A...
The tables below detail the maximum turns that the ID-6 can drive at 5 amps for loops with differing dimensions, of course less turns and lower currents can be used.
Front Panel Overview HF COMP (High Frequency Compensation) allows the frequency • response of the ID-6 to be modified to counteract the effects of metal in the vicinity of the installed loop. Rotating the control clockwise increases the amount of HF Comp applied (increases the high frequency whilst reducing the lower frequency relative to 1Khz).
ID-6B Battery Operation The standard ID-6 does not have a built-in backup power supply. If continued operation in a power outage is required, two options exist: Connect the ID-6 to an existing backup power source. This could be a generator or other system already in place at your facility/ venue.

Some specifiers and installers may wish to provide their own battery. Batteries with a capacity of less than 1000mA/H must not be used: they may be damaged by over-charging. It is the responsibility of the specifier and installer to ensure that suitability of any battery that is used.
Hearing Loop Set Up To ensure optimal performance of a ID-6/6B hearing loop driver, setup should be performed in following order: Step 1: Metal Loss (see page 20-21) Step 2: Output Level and Clipping (see page 21) Step 3: Field Uniformity (see page 21) Step 1: Metal Loss Position a Field Strength Meter in the centre of the hearing loop.

ting and record the value measured. 10. If the difference between the values measured at 1000Hz and 5000Hz is less than 3dB, record the results and move on to Step 2: Output Level and Clipping. If the difference is higher than 3dB, rotate the HF comp adjustment clockwise until the difference between the values measured at 1000Hz and 5000Hz is less than 3dB, record the results and move on to Step 2: Output Level and Clipping.
Mechanical / Mounting The ID-6 offers two mounting options: Flat Face Mounting: Secure the device to a flat surface using • the four mounting holes. We recommend using M3 countersunk screws. A set of universal wall plugs and screws are provided for installation.
Page 23
M3 bolts are required for this mounting option (not supplied). 112mm (4.4”) When using the edge mounting option, ensure the screws you use are no longer than 10mm (0.3”). This is important to avoid internal damage to the ID-6.
