Sennheiser CHG 70N-C Two-Bay Network-Enabled Charger for EW-DX Series - 700332

Product Overview

The Sennheiser CHG 70N-C is a two-bay network-enabled charger designed for EW-DX series wireless transmitters, sold without a power supply unit (PSU sold separately, or see the CHG 70N-C + PSU KIT at creationnetworks.net). Each bay simultaneously and independently charges an EW-DX SK bodypack, EW-DX SKM or SKM-S handheld transmitter, or a standalone BA 70 lithium-ion battery pack. The built-in RJ45 Ethernet port connects the charger to your network for remote monitoring and control via Sennheiser Control Cockpit software or Wireless Systems Manager (WSM), making the CHG 70N-C a central element of any managed EW-DX wireless infrastructure.

Power is supplied either via Power over Ethernet (PoE, IEEE 802.3af Class 0) from a PoE-capable switch or injector, or via the optional NT 12-35 CS power supply (12 VDC, 3.5 A) connected to the DC input. PoE operation simplifies deployment by eliminating a dedicated power cable run to each charger — a single Ethernet cable carries both data and power. Up to five CHG 70N-C units can be cascaded together with only a single network connection and one power supply required across the chain, dramatically reducing infrastructure complexity for large EW-DX installations. Full charge time is approximately 3.5 hours, with 80% charge achieved in roughly 2 hours. A color LED indicator at each bay provides at-a-glance charge status without requiring a networked device to check. The charger supports the Media Control Protocol over its RJ45 interface, enabling integration with third-party media control systems in broadcast galleries, houses of worship, and managed AV environments. At 7.9 x 4.6 x 4.1 inches and 1.4 lb, the CHG 70N-C is compact enough for equipment rack shelves, table deployment, or wall-mount in backstage and broadcast environments. Note: This listing is for the charger only, without PSU. The NT 12-35 CS power supply and the complete CHG 70N-C + PSU KIT are available separately at creationnetworks.net.

Key Features

• Two Independent Charging Bays — Simultaneously charges two EW-DX SK bodypacks, SKM handhelds, or BA 70 battery packs in any combination.
• Network Monitoring via RJ45 — Ethernet connectivity for remote status monitoring and control via Sennheiser Control Cockpit or WSM software.
• Media Control Protocol Support — Integrates with third-party media control systems for broadcast, AV, and installed sound environments.
• Power over Ethernet (PoE) — IEEE 802.3af Class 0 PoE support eliminates a separate power cable; one Ethernet run powers and connects the charger.
• Cascade Up to 5 Units — Chain up to five CHG 70N-C chargers on a single network connection and power supply for scalable fleet charging.
• 3.5-Hour Full Charge — Full capacity in approximately 3.5 hours; 80% charge achieved in approximately 2 hours.
• Per-Bay LED Status Indicators — Colored LEDs at each bay provide immediate, at-a-glance charge status without accessing software.
• 12 VDC DC Input — Compatible with the optional NT 12-35 CS power supply (12 VDC, 3.5 A) when PoE is not available.
• Compact and Rack-Friendly — 7.9 x 4.6 x 4.1 in / 200 x 116 x 104 mm footprint suits rack shelves, table deployment, and backstage environments.
• EW-DX Ecosystem Compatibility — Works with EW-DX SK bodypack, EW-DX SKM and SKM-S handheld transmitters, and standalone BA 70 battery packs.

Typical Applications

• Fleet charging and battery management for EW-DX wireless systems in broadcast studios
• Houses of worship managing multiple EW-DX handhelds and bodypacks between services
• Corporate AV installations with centralized wireless transmitter charging and monitoring
• Theatre and performing arts venues requiring overnight network-monitored charging
• Broadcast ENG facilities integrating charger status into media control workflows
• Rental companies managing EW-DX transmitter fleets with Control Cockpit software

Technical Specifications

Frequently Asked Questions

Q: Does the CHG 70N-C come with a power supply?

No. This listing is for the charger only, without PSU. You can power it via PoE from a compatible network switch or injector, or add the optional NT 12-35 CS power supply separately. The CHG 70N-C + PSU KIT bundle is also available at creationnetworks.net.

Q: Which transmitters and batteries are compatible with the CHG 70N-C?

The CHG 70N-C charges EW-DX SK bodypack transmitters, EW-DX SKM and SKM-S handheld transmitters, and standalone BA 70 lithium-ion battery packs. It is not compatible with EW-DP or EW-D series transmitters.

Q: Can I use the CHG 70N-C without a network connection?

Yes. Network connectivity is optional — the charger functions as a standard 2-bay charger without an Ethernet connection. The RJ45 port is only required if you want remote monitoring and control via Control Cockpit, WSM, or a media control system.

Q: How many CHG 70N-C units can I chain together?

Up to five CHG 70N-C units can be cascaded on a single network connection and power supply, allowing you to charge up to 10 transmitters simultaneously with minimal cabling.

Q: What software is used to monitor the CHG 70N-C over the network?

The CHG 70N-C is compatible with Sennheiser Control Cockpit (web-based) and Wireless Systems Manager (WSM) software. It also supports the Media Control Protocol for integration with third-party AV control systems.

Q: What does the LED indicator show at each bay?

A colored LED at each bay indicates charge status: charging in progress, charge complete, or an error condition. This allows quick visual inspection without needing to access monitoring software.

Q: What is the charge time for EW-DX transmitters?

A full charge takes approximately 3.5 hours. Approximately 80% charge is reached in around 2 hours, suitable for a quick top-up between sets or services.

Q: Can the CHG 70N-C be powered by PoE from a standard network switch?

Yes, provided the switch or injector supports IEEE 802.3af Class 0 PoE. This eliminates the need for a separate power supply at each charger location, simplifying installation in racks and wall-mount positions.
