The transmitter connects directly to your surround set's speaker output, so volume is always synchronised with the main system — no manual matching required. The receiver includes a built-in amplifier that drives up to 2 × 50 W (2 × 25 W RMS), making it compatible with standard passive speakers.\u003c\/p\u003e\n\u003cp\u003eThe 2.4 GHz digital link carries uncompressed audio with an overall latency of 20 ms or less, and the transmitter\/receiver pair uses secure ID pairing so multiple sets can coexist in the same room (up to six pairs). The improved 2.4 GHz technology is designed to avoid interference with existing Wi-Fi equipment operating on the same band.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eUncompressed digital audio transmission at 2.4 GHz — better than CD quality, no interference, no audible delay\u003c\/li\u003e\n\u003cli\u003eBuilt-in amplifier in the receiver: 2 × 50 W (2 × 25 W RMS), sufficient to drive standard passive rear speakers\u003c\/li\u003e\n\u003cli\u003eVolume automatically tracks the surround set volume via direct speaker-output connection\u003c\/li\u003e\n\u003cli\u003eSecure ID pairing — up to 6 pairs can operate in the same room without cross-talk\u003c\/li\u003e\n\u003cli\u003eImproved 2.4 GHz technology minimises interference with existing Wi-Fi equipment\u003c\/li\u003e\n\u003cli\u003eVolume control on the receiver enables independent front\/rear speaker balance adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eNo speaker cables need to run along skirting boards or through walls to the rear speakers\u003c\/li\u003e\n\u003cli\u003ePassive speakers you already own can be used directly — no powered speakers required\u003c\/li\u003e\n\u003cli\u003eLatency of 20 ms or less keeps audio in sync with video on screen\u003c\/li\u003e\n\u003cli\u003eSignal to noise ratio of 80 dB and channel separation of 50 dB or more preserve audio quality\u003c\/li\u003e\n\u003cli\u003eMultiple pairs in the same area do not interfere with each other, making it suitable for adjacent rooms\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Surround Anywhere 221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter supply voltage:\u003c\/strong\u003e 230 VAC +10% −15% 50 Hz, 5 V \/ 600 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter idle power consumption:\u003c\/strong\u003e \u0026lt;0.5 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio transmission method:\u003c\/strong\u003e Digital (uncompressed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter frequency:\u003c\/strong\u003e 2.4 GHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter pairing:\u003c\/strong\u003e Secure ID pairing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSample frequency:\u003c\/strong\u003e 48 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudio input level (max):\u003c\/strong\u003e 11 V (RMS) @ 120 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmitter operating range:\u003c\/strong\u003e max. 30 m line of sight;
