SZI 1015 (product page)

Summary

Sennheiser's catalogue page for its 2-watt infrared radiator, now marked as no longer available to buy.

Key findings

• States: "This product is no longer available to be purchased".
• Describes the SZI 1015 as a 2-watt radiator for infrared transmission systems covering up to 400 m², supporting carrier frequencies of 2.3 and 2.8 MHz in single-channel, two-channel or stereo operation, switched on and off by the modulator's carrier and able to be daisy-chained.
• Names no successor product.

Limits

An undated product page with no explanation: it shows that this radiator is no longer sold, not whether the maker has left infrared altogether. Sennheiser's spare-parts catalogue still lists its infrared modulators, radiators and receivers for service.
