Up to 15 hours of battery life on a single charge ensures the system can support full-day events without interruption. Available in four frequency sub-bands (DW-3 through DW-6) to optimize performance in various installation environments.

Product Description

The SL Bodypack – HS 2 KIT is part of Sennheiser's SpeechLine Digital Wireless (SL DW) ecosystem, a purpose-built platform for corporate and institutional audio-visual installations where speech intelligibility and operational simplicity are paramount. The SL Bodypack DW transmitter is engineered around digital DECT transmission at 1.9 GHz, a spectrum that is specifically allocated for voice applications and experiences far less interference than traditional UHF wireless systems in congested enterprise environments. Bi-directional communication between the transmitter and the SL Multi-Channel Receiver DW means channel assignment, frequency management, and interference avoidance happen automatically — no RF expertise required of the operator. The transmitter's LC display shows link name, battery charge level, and reception quality at a glance, while the accessible mute switch allows discreet silencing during sessions. The included HS 2 BE headset microphone uses the renowned MKE 2 Gold condenser capsule, delivering exceptional clarity for speech and voice transmission. Its robust steel wire cable is built to withstand the rigors of daily use in high-traffic corporate environments, and the short gooseneck provides precise mic positioning without obstructing the speaker's face. The SL Bodypack DW is equipped with a lithium-ion rechargeable battery pack with external charging contacts, compatible with the Sennheiser CHG 4N 4-bay network charger for organized fleet management. USB charging is also available for flexibility. Lockable 3.5 mm jack connectivity ensures the HS 2 won't accidentally disconnect mid-presentation. Remote control capability via Sennheiser Control Cockpit allows AV managers to monitor and adjust transmitter settings from a central interface without entering the room. With AES 256-bit encryption standard, conversations remain secure in sensitive corporate and government settings. The SL Bodypack – HS 2 KIT is available in four frequency sub-bands (DW-3, DW-4, DW-5, DW-6) to accommodate different regional DECT band allocations and installation requirements.

Frequently Asked Questions

Q: What receiver is required for the SL Bodypack – HS 2 KIT?

The SL Bodypack DW transmitter is designed for use with the Sennheiser SL Multi-Channel Receiver DW. The SpeechLine ecosystem uses bi-directional communication between compatible transmitters and receivers, enabling automatic frequency management and remote control. This kit does not include a receiver — it must be purchased separately.

Q: Why choose 1.9 GHz DECT over traditional UHF wireless systems?

The 1.9 GHz DECT band is internationally allocated specifically for voice communications and experiences dramatically less interference than UHF bands that are increasingly congested with broadband, TV, and other wireless systems. In corporate and institutional environments with many concurrent wireless devices, DECT provides more stable and predictable performance.

Q: Can multiple SL Bodypack – HS 2 KIT transmitters be used simultaneously?

Yes. The SpeechLine Digital Wireless system is designed for multi-channel operation. Multiple SL Bodypack DW transmitters can be managed through the SL Multi-Channel Receiver DW and Sennheiser Control Cockpit, making it scalable for large conference rooms and auditoriums.

Q: Is the HS 2 microphone compatible with other Sennheiser bodypacks?

The HS 2 BE uses a standard 3.5 mm locking jack connector. It is specifically optimized for use with SpeechLine Digital Wireless bodypacks but may be compatible with other Sennheiser transmitters using the same connector type. Consult the Sennheiser compatibility guide or contact Creation Networks for specific pairing advice.

Q: How is the SL Bodypack DW charged?

The SL Bodypack DW features external charging contacts for use with the Sennheiser CHG 4N 4-bay network charger, which supports organized fleet charging and battery status monitoring. It also includes a USB socket for charging via any standard USB power source — useful for travel or when the CHG 4N charger is not available.

Q: What frequency sub-band should I choose — DW-3, DW-4, DW-5, or DW-6?

The DW frequency sub-bands correspond to different portions of the 1.9 GHz DECT spectrum and are allocated by region. In North America, specific sub-bands are approved for use. Contact Creation Networks or consult Sennheiser's regional frequency guide to determine the correct sub-band for your country and installation environment.

Q: Does the SL Bodypack DW support encryption for confidential meetings?

Yes. AES 256-bit encryption is built into the SpeechLine Digital Wireless system as a standard feature — not an optional add-on. Every audio transmission is fully encrypted, making it suitable for boardrooms, legal proceedings, government sessions, and any environment where audio privacy is a requirement.

Q: Can Creation Networks assist with a SpeechLine wireless system design for my facility?

Yes. Creation Networks provides professional AV system design and Sennheiser product expertise for corporate, institutional, and house-of-worship installations. Visit creationnetworks.net to explore the full SpeechLine catalog and contact us for a tailored wireless audio solution.
