Sennheiser XSW IEM Wireless In-Ear Monitoring A: 476 - 500 MHz

Sennheiser XSW IEM Band A — Professional Wireless In-Ear Monitoring Made Simple

The Sennheiser XSW IEM Band A is a turnkey wireless in-ear monitoring system that brings the brand’s renowned personal monitoring sound to performers stepping up from wedges and budget setups. Operating in the UHF range of 476–500 MHz, musicians, vocalists, and worship teams receive a clean, reliable signal for rehearsals, club stages, and mid-sized venues. Included are all components required to start monitoring immediately: stereo transmitter, bodypack receiver, IE 4 in-ear headphones, AA batteries, multi-voltage power supply with country adapters, and a rack mount kit. No technical expertise is needed to dial in a personal mix and focus on your performance.

What Stands Out in This System’s Class

Two features give this model genuine pro-tier capability at an entry-level price. The infrared sync allows unlimited receivers to pair with a single transmitter in seconds, which is ideal for band-wide setups. Directly from the bodypack, Focus mode lets each performer prioritize one input over another for a user-specific experience — a flexibility usually reserved for higher-end systems. The combination of wideband FM modulation, 30 mW RF output power, and an integrated limiter with selectable high-frequency EQ boost results in a product that outperforms many in this segment.

Wireless Transmission & Frequency Management — Reliable UHF Coverage

Benefit from the professional UHF band, which is the gold standard for live IEM systems, thanks to its immunity from congested 2.4 GHz Wi-Fi and 900 MHz ISM interference. Eight pre-configured frequency banks, each with 12 perfectly aligned channels, ensure stable connections, while manual frequency tuning is at your disposal in challenging RF environments.

• Frequency Range (Band A): 476–500 MHz — keeps you clear of Wi-Fi congestion
• Switching Bandwidth: up to 24 MHz — flexible frequency selection across the band
• RF Output Power: 30 mW — strong signal for stage-to-pack reliability
• Modulation: Wideband FM stereo — full-bandwidth audio transmission

Transmitter & Bodypack Specs — Built for the Stage

Mount the metal-housed stereo transmitter in a half-rack space and pair it with a high-impact bodypack receiver that easily clips to a belt or strap. Inputs are electronically balanced combo sockets. The stage-proof panel keeps your settings protected from accidental bumps, with a status LED and LC display visible at a glance.

• Transmitter Dimensions: approx. 200 × 128 × 42 mm — half-rack form factor
• Antenna Output: BNC socket, 50 Ω — supports external antennas and combiners
• AF Inputs: 2× XLR-3 / 1/4" combo, electronically balanced — stereo or dual-mono configuration
• With receiver power supplied by 2× AA batteries (1.5 V), approx. 6 h runtime, you get a full set of batteries in the box to start your performance.

Audio Performance & IE 4 Headphones — Sound That Translates

Expect flat, accurate audio quality spanning 45 Hz to 15 kHz, with a signal-to-noise ratio of ≥88 dB and total harmonic distortion under 1%. The included IE 4 headphones feature dynamic transducers with a range of 40 Hz–20 kHz and 106 dB SPL, paired with exchangeable sleeves for secure isolation from stage noise.

• AF Frequency Response: 45 Hz–15 kHz — full-range monitoring for vocals and instruments
• Signal-to-Noise Ratio: ≥88 dB — clean, hiss-free monitoring
• High Boost EQ: +10 dB at 13 kHz — selectable on-pack high-frequency lift
• To protect your ears from sudden volume spikes, the Limiter reduces gain by −10 dB.
• IE 4 SPL: 106 dB at 1 kHz, 1 mW — confident output even in loud stage environments

Who Is It For — Performers, Worship Teams, and Touring Acts

The Sennheiser XSW IEM Band A is suited for working musicians, church worship teams, and small-to-mid venue performers needing dependable monitoring without the expense or complexity of flagship systems. Drummers, keyboard players, and vocalists who struggle to hear themselves through wedges will benefit from a customized stereo or focus mix delivered directly to their ears. System expandability — unlimited receivers per transmitter — makes this instrument ideal for bands outfitting multiple players on one RF budget.
