HDI 1029Infrared Wireless Systems | Receivers

The HDI 1029 is a multi-channel narrow-band stethoset receiver. Depending on the model, it can be switched between 8 or 16 channels. Due to this multi-channel design, it is ideally suitable for use at international conferences. The stethoset receiver is an economical alternative to the bodypack receiver with its “external” head-phone. Short events with a changing audience bring out the special advantages of this type of receiver: they can be quickly distributed and collected again as there is no cable to get entangled.

The transducers of the HDI 1029 are situated directly behind the ear pads. The result-ing sound quality is clearly better than that of systems using pneumatic transmis-sion. Moreover, the stethoset design clearly attenuates ambient noise, values of up to 15 dB having been achieved. This attenuation for example increases the intelligi-bility of translations when the floor language is being reinforced at the same time. The operating controls of the HDI 1029 – a combined on/off/volume control and a channel selector switch – are located at the bottom of the receiver where they are protected against coffee splashes etc. After use, the receiver should always be switched off. The IR receiving diodes are located on the front of the receiver. Thus, the users always have good reception as long as the diodes do not face the body.

The HDI 1029 has a built-in squelch. When the IR signal from the radiators becomes too weak, the receiver mutes the audio output in order to avoid loud hiss. During conference breaks, this muting circuit serves to save energy. The receiver switches to stand-by so that the BA 90 accupack is not discharged too quickly. The environ-mentally friendly BA 90 has a weight of only 8 g and allows an operating time of appx. 10 hrs with the HDI 1029. The various possibilities for recharging the BA 90 are decribed below.

The silicone earpads of the HDI 1029 can easily be removed and cleaned. Never-theless, they are tightly attached to the headphones to prevent them slipping off accidentally.

If you want to recharge several BA 90 at the same time, you should use the L 92-10 or L 92-20 charging unit for up to ten or up to twenty accupacks. The BA 90 are inserted into the units from both sides, and recharging is indicated by the LEDs on top of the charging unit.

However, the best solution is to recharge the accupacks while they remain inserted in the receivers. The L 1030-10 charging unit can recharge up to ten complete receiv-ers. It is powered by the plug-in mains unit NT 92, which is suitable for up to two L 1030-10. For up to five cascaded units, you can use the NT 2013 or NG 2013-UK. The necessary plug-in mains units are not delivered with the charging units. Please order them separately in the version you require (European, UK and USA versions available).

The L 29-50-2 charging and transport case makes storing and recharging still easier. The charging case can accommodate up to 50 HDI 1029, the accupacks remain in the receivers and recharging is timer-controlled. Power is supplied via an NT 2013 (or NG 2013-UK) plug-in mains unit which must be ordered separately. The BA 90 accu-packs cannot be overcharged, so they can remain in the charging units even when they have been fully recharged, which takes approximately 14 hrs. The charging unit in the L 29-50-2 automatically switches over to trickle charging after 14 hours.
