Digital wireless 5.8GHz TX/RX charging base - SWIFF AUDIO SWF-WX503

The SWIFF AUDIO WX-503 Digital Wireless System pairs a transmitter with a receiver for stable, interference-free audio, and several TX / RX sets can run together on one show. Its 5.8 GHz digital link preserves excellent sound while keeping latency below 5 ms, so players hear themselves instantly on stage; the radio path also resists crowding from other wireless services.

Any source with a 6.3 mm jack can be wired in, and noise cancellation suppresses the loud thump if the TX is pulled off the instrument unexpectedly. A (double) press on the function key lights a 4-LED bar with charge data for both transmitter and receiver. Compact, rugged mechanics survive heavy touring, and the straightforward UI speeds initial setup.

Audio bandwidth spans 20 Hz to 20 kHz, SNR is above 90 dB and reception sensitivity is below -110 dBm @ 20 dBsinad, while transmission distance exceeds 30 m. Supplied accessories include a USB Type-C high-speed charging dock built around a 5200 mAh lithium polymer pack (19.2 Wh) with IN 5 V DC 2 A and OUT 5 V DC 2 A, good for up to three full refills of the WX-503 TX and RX or for topping up phones and tablets. The box adds a charging bay, storage bay, Type-C charging cable and user manual, and the system provides 4 channels. Highlights: 5.8 GHz band for clear audio and fewer clashes with Wi-Fi and other wireless gear; simple controls; disconnect pop protection; shared charging case that triples runtime between wall sessions. Typical users: professional and amateur musicians, rehearsal and teaching rooms, project studios, concerts and live performances, events and audiovisual productions.
