The result is a complete, ready-to-use wireless microphone system that lets instructors focus entirely on their class rather than their equipment.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eProfessional UHF Wireless Performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe S4.10W is built around Trantec's fully synthesised PLL quartz tuning technology, delivering stable, reliable and interference-free UHF wireless performance across up to 10 simultaneous channels. The receiver features antenna diversity operation with a detachable antenna, ensuring consistent signal reception and minimising dropouts as the instructor moves around the studio or gym floor. Receiver LEDs provide clear real-time monitoring of AF peak level, RF level and diversity channel A or B status at a glance. The system is available in two frequency variants — Channel 70 (licence-free, four switchable frequencies) and Channel 38 — please select your required version before adding to basket. Please note that Channel 38 operation requires a PMSE licence.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCompact, Robust \u0026amp; Easy to Use\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe beltpack transmitter is housed in a professional resin and coating finish enclosure, measuring just 62 x 100 x 25mm and weighing only 85g with battery — small and lightweight enough to be worn comfortably throughout an entire fitness class without distraction. A single AA alkaline battery powers the beltpack for approximately 10 hours, making it more than sufficient for a full day of back-to-back classes without the need for a battery change. The included neoprene aerobic belt (ACC-AB1000) is designed to hold the beltpack securely against the body during vigorous movement, keeping the transmitter stable and the cable managed neatly throughout the session.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVersatile Receiver Connectivity\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe receiver provides both balanced XLR and unbalanced ¼\" jack audio outputs for straightforward connection to a wide range of PA amplifiers, mixers and installed audio systems. A 12V DC power supply is required for the receiver. The compact receiver chassis — measuring 215 x 39 x 102mm — can be used freestanding or rack-mounted in a standard 19\" rack enclosure, with options for single or dual receiver mounting, making it equally suitable for permanent gym or studio installations and portable setups.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eTrantec S4.10-W-EB Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePurpose-Built for Fitness Instruction:\u003c\/strong\u003e Complete system designed specifically for aerobic, spinning and gym class instructors requiring reliable hands-free wireless audio during high-energy sessions.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eNeoprene Aerobic Belt Included:\u003c\/strong\u003e ACC-AB1000 aerobic belt securely holds the beltpack transmitter in place throughout vigorous movement and activity.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHeadset Microphone Included:\u003c\/strong\u003e MIC-SJ66 sweat-proof headset microphone in black.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eChannel 70 or Channel 38 Available:\u003c\/strong\u003e Licence-free Channel 70 (4 switchable frequencies) or Channel 38 — select your required version.
