CONTACTA LOOP DRIVERS - HLD Series

The HLD series hearing loop amplifiers enhance accessibility to music and speech in larger areas than can be covered with one-to-one or portable loop systems.

HLD5

This stand-alone, dual output hearing loop driver can provide up to 3A RMS, 7V RMS per output channel. It is for use in perimeter or phased-array configurations in smaller rooms, such as meeting rooms, classrooms and reception and waiting areas. Four inputs, two microphone and two line level, are by way of 3-pin Euroblock (Phoenix style, detachable terminal block) connector while a 2-pin connector can be used for a 100V line input. The two microphone inputs can be used balanced or unbalanced depending on wiring; a miniature (DIP) switch selects 12V or 5V phantom power. Input gain control and high frequency compensation can be adjusted via dedicated and recessed screwdriver-operated controls. Automatic gain control with a dynamic range of 40dB typical, an attack time of 10mS, and a release time of 500mS can be applied, with LEDs indicating 'Level Good'. Miniature (DIP) switches control the phased array, perimeter A or B, perimeter A+B output configurations; LEDs provide valuable feedback on output status, fault detection and power.

Dimensions: 99 x 200 x 40 (HxWxD) mm. Weight: 1.5kg.

HLD7

This single output hearing loop driver is housed in a 1U, half rack-width' aluminium case. It is designed for use in medium sized venues such as lecture halls, small theatres, and places of worship. A single HLD7 can be used to provide a perimeter loop system, or two HLD7 amplifiers linked by a RJ45 cable from the 'Expansion' socket provide a phased array configuration.

The front panel features all mode and level adjustment controls in the way of '+' and '-' press buttons. Both microphone and line inputs have LED bar-graphs to display the level; a third LED bar graph displays the drive (output) level for the amplifier. Three individual LEDs for the microphone channel indicate 'clip', 'active' (signal detected), and 'PHTM' (12VDC phantom power). Three individual LEDs for the LINE level input indicate 'clip', 'active', and 'LOW SIG' (low signal detected). Two final LED sections display perimeter/primary/secondary configuration, and power/status.

The rear panel houses all I/O connectivity including the 24V DC power input (a 2.1mm 'DC jack') and 'MIC' and 'LINE' inputs on balanced XLR and 6.3mm jack combination connectors. A loop output connector via 4-pole speakON connector provides an output voltage of 15V RMS with a current of 6A RMS. A 3-pin, voltage-free, SPCO (single pole change over) relay connection is provided for external compatible equipment. A toggle push- switch enables/disables 12V DC phantom power.

Dimensions: 44.5 x 200 x 260 (HxWxD) mm, 1U height. Weight: 2.5kg.

HLD9

The HLD9 hearing loop driver has been designed for larger venues such as theatres, conference facilities, concert halls, and sports arenas whereby a single HLD9 can be configured to provide a perimeter loop system, or two HLDs can be linked to provide a phased array system. Provides 36V RMS and 10A RMS.

All panel controls on the front panel are as the HLD7. Connectivity on the rear panel is similar to the HLD7, with the exception of the power inlet which is an AC IEC inlet.

Dimensions: 63 x 200 x 266 (HxWxD) mm, 2U rack mounting. Weight: 2.5kg

Optional accessories

MBR1 Rack mounting bracket for single HLD7 hearing loop amplifier, 1U
MBR2 Rack mounting bracket for two HLD7 hearing loop amplifiers, 1U
MBR1-9 Rack mounting bracket for single HLD9 hearing loop amplifier, 2U
MBR2-9Rack mounting bracket for two HLD9 hearing loop amplifiers, 2U

IL-RX20

The IL-RX20 Loop Listener is a compact listening device designed for use and interaction with hearing loop systems whereby an engineer can listen to the hearing loop system as though they were wearing a compatible hearing aid switched to the 'T' position. The two included alkaline AAA batteries will give more than 100 hours life; a rotary volume control doubles as on/off switch. An LED illuminates to signify power on. The included headphones are connected via 3.5mm jack socket located on the top of the IL-RX20.

Dimensions: 240x165x40 (HxWxD) mm. Weight: 550g, with headphones.

Note: Contacta products are only available for sale to customers in the UK and Ireland.
