The Samson AirLine 77 Fitness E4 is the ideal companion for fitness classes, dynamic presentations or stage performances. Thanks to its all-in-one design, the AH7 headband microphone integrates the transmitter directly into the headband: no more annoying belts or cables during exercise.
Its Qe condenser capsule provides precise, natural voice pick-up, while its sweat-resistant structure makes it perfectly suited to environments such as sports halls or dance stages.

Operating on the E4 band (864-875 MHz), the system guarantees a range of 90 metres in open field and up to 8 hours' autonomy on a single AAA battery. The built-in LED indicator warns you when the battery is running low, so there's no chance of a surprise power cut.

On the reception side, the CR77 uses a True Diversity dual-antenna design to ensure exemplary signal stability, even in busy environments. The half-rack chassis fits easily into a flight case or fixed installation, and the XLR and 6.35 mm jack outputs allow connection to any console or powered loudspeaker.

With a frequency response of 50 Hz to 15 kHz and a signal-to-noise ratio of 90 dB, the Samson AirLine 77 Fitness E4 combines mobility and reliability for those who live their sound without ever lifting a foot.
