Sennheiser CHG 4N US 4 Bay Charger - 506802

Product Overview

The Sennheiser CHG 4N US is a 4-bay network-enabled charger designed specifically for SpeechLine Digital Wireless transmitters — the SL Bodypack DW and SL Handheld DW. Purpose-built for permanent AV rack installations in conference rooms, boardrooms, and lecture hall facilities, the CHG 4N provides organized simultaneous charging of up to four transmitters while delivering real-time battery status monitoring via its network interface. Integration with Sennheiser Control Cockpit allows AV administrators to remotely monitor charger and battery status across the entire SpeechLine fleet from a single management dashboard. The CHG 4N is the essential infrastructure component for any facility operating multiple SpeechLine wireless systems in high-turnover, all-day event environments.

Product Description

Managing a fleet of wireless microphone transmitters in a busy corporate or institutional environment demands more than just a place to plug them in — it requires intelligent infrastructure that keeps equipment ready, status visible, and operations seamless. The Sennheiser CHG 4N US 4-Bay Network Charger is precisely that infrastructure. Engineered as a companion to the SpeechLine Digital Wireless ecosystem, the CHG 4N accommodates four SL Bodypack DW or SL Handheld DW transmitters simultaneously, with each bay operating independently and displaying its own battery status via dedicated LED indicators. The flexible network interface supports both IPv4 and IPv6 addressing, enabling seamless integration into modern enterprise LAN environments without compatibility concerns. Through Sennheiser Control Cockpit — Sennheiser's centralized AV management software — facility managers can remotely monitor charge levels, device health, and charger status without physically visiting each charging station, dramatically reducing the time AV staff spend on equipment checks before events. Each bay's LED status indicators provide an at-a-glance view of charging progress directly on the unit itself, allowing quick visual checks when walking past a rack. The CHG 4N is rack-mountable and designed for permanent installation in AV equipment racks, head-end closets, or front-of-room credenzas. Its RJ45 network connector provides a standard, reliable connection to the facility LAN. With dimensions of 270 x 100 x 102 mm and a weight of approximately 1,100 g (without power supply), the CHG 4N is compact enough to fit into standard AV racks without consuming excessive rack space. The SKU 506802 unit is the US-market version with appropriate power specifications for North American installations. For facilities operating SpeechLine Digital Wireless systems at scale — multiple conference rooms, tiered auditoriums, or enterprise-wide deployments — the CHG 4N is not optional infrastructure; it is the operational backbone that keeps transmitters charged, organized, and monitored.

Technical Specifications

Frequently Asked Questions

Q: Which Sennheiser transmitters are compatible with the CHG 4N charger?

The CHG 4N is designed for the SL Bodypack DW and SL Handheld DW transmitters from the Sennheiser SpeechLine Digital Wireless ecosystem. It is not compatible with non-SpeechLine transmitters such as EW G4 bodypacks or Digital 9000 series units.

Q: Does the CHG 4N require network connectivity to function as a charger?

No. The CHG 4N will charge transmitters placed in its bays regardless of whether it is connected to a network. Network connectivity is required only for remote monitoring and management via Sennheiser Control Cockpit — charging itself is a standalone function.

Q: How many CHG 4N units can be monitored through Sennheiser Control Cockpit?

Sennheiser Control Cockpit supports multi-device management across an enterprise network, meaning multiple CHG 4N chargers across different rooms or floors can be monitored from a single dashboard. The exact number of managed devices depends on your Control Cockpit license and network configuration.

Q: Can the CHG 4N charge SL Bodypack DW and SL Handheld DW transmitters in the same unit simultaneously?

Yes. The four bays are independent and can accommodate a mix of SL Bodypack DW and SL Handheld DW transmitters simultaneously within the same charger unit, making it ideal for mixed-fleet conference environments.

Q: Is the CHG 4N rack-mountable?

The CHG 4N is designed for permanent installation in AV rack environments. Its compact dimensions of 270 x 100 x 102 mm make it suitable for integration into standard equipment racks. Confirm rack mounting hardware compatibility with your specific rack configuration or consult Creation Networks for installation guidance.

Q: What does the US designation on the CHG 4N US mean?

The "US" designation indicates this model is specified for North American power standards (120V/60Hz). If you are installing outside North America, ensure you select the appropriate regional variant to match local power infrastructure.

Q: How do the LED status indicators work on the CHG 4N?

Each of the four charging bays has its own set of LED indicators that display the battery charge status of the transmitter in that bay. LED behavior (colors and patterns) indicates whether the battery is charging, fully charged, or in a fault state, allowing quick visual inspection without accessing the management software.

Q: Can Creation Networks help design a complete SpeechLine Digital Wireless system including charging infrastructure?
