Ideal for theatrical productions, fitness instruction, presentations, conferences, houses of worship, schools and live performances where a headset microphone offers advantages over a lapel solution, the S4.10A delivers stable, interference-free UHF wireless performance with 16 selectable frequencies and support for up to 10 simultaneous channels.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe S4.10A is available in two frequency variants — Channel 70 and Channel 38 — please select your required version before adding to basket. Channel 70 operates within the licence-free UHF band, requiring no PMSE licence for use in the UK. Channel 38 offers an alternative frequency option and requires a PMSE licence for operation. Both variants deliver the same professional performance and feature set.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eReliable Diversity Reception\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe S4.10A receiver features antenna diversity operation with a detachable antenna, ensuring consistent signal reception and minimising dropouts as the performer or presenter moves around the stage or venue. Receiver LEDs provide clear real-time monitoring of AF peak level, RF level and diversity channel A or B status — giving the operator a clear and instant overview of system performance at all times. Three squelch systems — Tone SQ, Carrier SQ and Noise SQ — work together to ensure a clean, noise-free output signal. The compact professional metal receiver chassis measures 215 x 39 x 102mm and can be used freestanding or rack-mounted in a standard 19\" rack enclosure, with options for single or dual receiver mounting for permanent venue installations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCompact Beltpack Transmitter\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe S4.10A beltpack transmitter is an exceptionally compact and lightweight unit, measuring just 62 x 100 x 25mm and weighing only 85g with battery — small and light enough to be worn comfortably throughout an entire performance, presentation or fitness session without distraction. Powered by a single AA alkaline battery, the beltpack provides approximately 10 hours of continuous use on a single battery — more than sufficient for a full day of back-to-back sessions.
