Samson AirLine 77 Guitar System AF1 (N2) - UHF Wireless Guitar/Bass System without Bodypack (with True Diversity Receiver)

The Samson AirLine 77 Guitar System AF1 is a wireless guitar and bass system that completely eliminates the need for a bodypack: the AF1 transmitter connects directly to the guitar via an angled 1/4" jack (designed for Fender/Stratocaster-style inputs with recessed connectors). The system includes the CR77 UHF True Diversity receiver , which provides link stability with A/B antenna indicators , RF and audio level LED meters , and balanced XLR and unbalanced 1/4" jack outputs switchable to Mic/Line level. The N2 version operates on the 642.875 MHz (UHF) channel , ideal for stages and backline applications that demand reliability.

The AF1 offers up to 14 hours of battery life on a single AAA battery and features a −15 dB pad for matching the output of high-gain instruments. The CR77 adds squelch control, mic/line level selection, and a typical range of up to 90 m (300 ft ) line-of-sight. It's a compact, straightforward solution for guitarists and bassists who want cable-free mobility and a simple workflow.
