Sennheiser XSW1-835 Dual Wireless set A: 548-572 MHz

Sennheiser XSW 1-835 Dual A-Band Wireless Vocal System

The Sennheiser XSW 1-835 Dual A-Band Vocal is a complete 2-channel UHF wireless package aimed at vocalists, duos, hosts, and presenters seeking dependable cable-free performance with minimal setup. By pairing two SKM 835-XSW handheld transmitters with a slim EM-XSW 1 DUAL receiver, this model offers simultaneous access to Sennheiser's evolution-series vocal sound on the A-band frequency range (548–572 MHz) for two performers.

Standout Features

Each handheld transmitter uses the renowned evolution e835 dynamic capsule, voiced for live vocals and tuned with a presence boost in the 3–5 kHz range so the voice projects clearly. With antenna-switching 2-channel diversity, automatic frequency management, and easy one-button channel sync, setup remains simple even in busy RF environments.

Wireless Performance and Signal Reliability

Maintaining a clean signal across a venue is essential, and the dual-channel receiver leverages antenna-switching diversity to continuously select the best reception path.

• Frequency Range: 548–572 MHz (A-band) — up to 10 compatible channels per set
• Switching Bandwidth: 24 MHz — allows flexible tuning in crowded RF spaces
• Receiver Principle: True diversity with antenna switching — reduces dropouts as performers move
• Artists performing on small-to-mid venue stages benefit from the Transmitting Power of 10 mW for reliable range.

Capsule and Vocal Character

The included e835 capsule has become a stage staple for both spoken and sung vocals, with a cardioid pattern to reject off-axis noise. Its upper-mid presence lift helps voices cut through without heavy EQ.

• Transducer Type: Dynamic — designed for high SPLs with no distortion
• Focused pickup pattern: Cardioid — isolates the singer's voice, limiting ambient stage sound
• Frequency Response: 50–16,000 Hz — covers full vocal range with clear highs
• Sensitivity: 1.8 mV/Pa — delivers a strong, clean signal for wireless use

Power, Outputs, and Connectivity

Transmitters are powered by standard AA batteries, making replacements easy and affordable. The receiver operates from the included NT 12-5 CW supply with country adapters. Each channel features balanced XLR and unbalanced 1/4" outputs, with selectable mic/line level and adjustable squelch.

• Battery Powered: Yes — two AA cells per transmitter
• Typical gig duration is supported by Battery Operating Time: approx. 10 hrs
• Connectors: 3-pin XLR plus 1/4" (6.3 mm) jack per channel — suitable for mixers or PAs
• Line / Mic Level: switchable, 20 dB pad — accommodates most mixer and recorder inputs

Who Is It For

The YRS-23 is a solid pick for solo singers, duos, karaoke hosts, small worship teams, school events, and presenters needing two ready-to-go vocal channels. Singers value the e835 capsule's proven live character, while venue staff enjoy true-diversity reception and the XS Wireless 1 series' fast setup. It's a practical upgrade for musicians seeking a move into Sennheiser's professional-grade wireless gear.

Sennheiser Wireless Heritage

Sennheiser's XS Wireless line was designed as a streamlined gateway into the professional wireless world, borrowing capsule technology from the evolution series that set the standard for live vocals. The e835 capsule, central to this set, is widely trusted on tour stages and now comes paired with the XSW 1 receiver platform for a hassle-free UHF wireless experience.
