The two-channel and stereo versions of Sennheiser’s new stethoset generation operate on the extremely reliable carrier frequencies 2.3 and 2.8 MHz. They are an ideal choice for applications where reproduction quality is paramount, e.g. for ste- reo music transmissions.

The most versatile of these receivers is the HDI 302, which can be switched between stereo operation and reception on channel 1 or 2. This option is very convenient when you are, for example, planning to set up a high-quality mini interpretation system. You could transmit two translations on channels 1 and 2 and reinforce the floor language via a PA system. The RI 300 product variant is a pure stereo receiver, which cannot be switched between channels.

The HDI 302 and RI 300 are fitted with a squelch which mutes the audio output when the IR signal becomes too weak, thus avoiding loud hiss. The receivers are powered by a BA 151 NiMH accupack which can be charged in the L 151-10 charging unit while remaining in the receivers. Optionally, the L 151-10 also charges spare

accupacks instead of an entire receiver. The charging unit is powered by an NT 92 plug-in mains unit. The L 151-2 charger charges two accupacks and is supplied com- plete with mains unit. For larger, professional applications, the charging units can be cascaded. Up to five L 151-10 are then powered via an NT 2013 (or NG 2013-UK) plug-in mains unit.
