DETAILS

The Trantec S4.10W is a professional UHF Headworn Wireless Microphone System purpose-built for fitness instructors, aerobic coaches and spinning class leaders — delivering reliable, hands-free wireless audio with a sweat-resistant headset microphone, neoprene aerobic belt and up to 10 hours of battery life.

The Trantec S4.10W has been specifically designed for the demands of fitness instruction environments — from aerobic and spinning classes to gym floor coaching, dance instruction and any other high-energy activity where a reliable, hands-free wireless microphone is essential.

Unlike general-purpose wireless systems, the S4.10W has been put together with the fitness instructor firmly in mind, combining a professional UHF wireless receiver with a compact beltpack transmitter, a dedicated headset microphone and a neoprene aerobic belt that keeps the beltpack securely in place during even the most energetic sessions. The result is a complete, ready-to-use wireless microphone system that lets instructors focus entirely on their class rather than their equipment.

Professional UHF Wireless Performance

The 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.

Compact, Robust & Easy to Use

The 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.

Versatile Receiver Connectivity

The 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.
