Sennheiser L 6000 - US Intelligent Charging Station for Digital 6000 & 9000 Series Transmitter Battery Packs

Product Overview

The Sennheiser L 6000-US is a 1 RU rackmount intelligent charging station designed to simultaneously recharge up to eight Digital 6000 and Digital 9000 series transmitter battery packs. With an internal power supply, an Ethernet port for remote monitoring via Wireless Workbench software, and per-bay three-color LED status indicators, the L 6000-US provides centralized, scalable battery management for professional touring, broadcast, and permanent installation environments. A modular four-dock design accepts LM 6060, LM 6061, and LM 6062 charging modules in any combination, accommodating handheld, bodypack, and mini bodypack battery packs from across the Digital 6000 and 9000 platforms.

Product Description

Managing battery logistics for a large wireless system inventory demands an infrastructure solution, and the Sennheiser L 6000-US is designed precisely for that role. The unit occupies a single rack unit and houses four docking positions, each of which accepts one charging module capable of charging two battery packs simultaneously — yielding a total capacity of eight packs per charge cycle. The modular architecture is the key operational advantage: LM 6060 modules charge BA 60 packs for SKM 6000 and SKM 9000 handheld transmitters, LM 6061 modules charge BA 61 packs for SK 6000 and SK 9000 bodypack transmitters, and LM 6062 modules charge BA 62 packs for the SK 6212 mini bodypack. Any combination of these modules can be installed in the four docks, allowing a single L 6000-US to service mixed fleets of handheld and bodypack transmitters. The intelligent charging system monitors each bay independently and actively controls four internal cooling fans to prevent heat buildup during charging cycles. A storage mode maintains battery packs at optimal charge levels during extended idle periods, extending overall battery health and longevity. Three-color LED indicators on each bay display charging status at a glance — no software required for basic operation. The Ethernet port connects the L 6000-US to Sennheiser’s Wireless Workbench software, enabling detailed remote monitoring of remaining charge times, run time estimates, charging cycle counts, battery quality assessments, and operating temperature data. This remote visibility is particularly valuable for broadcast and touring applications where a technical crew monitors system health from a central location. The internal power supply eliminates the need for external power adapters and simplifies rack cabling. The L 6000-US is also future-proof: charging modules for new battery pack types can be added as retrofits when the Digital platform evolves.

Technical Specifications

Frequently Asked Questions

Q: Does the L 6000-US come with charging modules included?

No. The L 6000-US base unit includes four empty docks but no charging modules. LM 6060, LM 6061, and LM 6062 modules are purchased separately based on which battery pack types your wireless transmitters use.

Q: How many battery packs can the L 6000-US charge simultaneously?

With all four docks filled, the L 6000-US charges up to eight battery packs simultaneously — two per charging module across four docking positions.

Q: Can the L 6000-US charge a mix of BA 60, BA 61, and BA 62 packs at the same time?

Yes. Each of the four docks can hold a different charging module type, allowing simultaneous charging of BA 60, BA 61, and BA 62 packs in any combination within the same unit.

Q: Which Sennheiser transmitters use the BA 60 versus BA 61 battery pack?

The BA 60 is used with SKM 6000 and SKM 9000 handheld transmitters (charged via LM 6060 module). The BA 61 is used with SK 6000 and SK 9000 bodypack transmitters (charged via LM 6061 module).

Q: What monitoring capabilities does the Ethernet connection provide?

When connected to Sennheiser’s Wireless Workbench software via Ethernet, the L 6000-US reports remaining charge times, estimated run times, charging cycle counts, battery quality status, and operating temperature for each bay.

Q: What is storage mode and when should it be used?

Storage mode keeps battery packs at an optimal partial charge level to preserve lithium-ion cell health during extended periods of non-use. It is recommended when battery packs will not be used for several days or more.

Q: Does the L 6000-US require an external power supply?

No. The L 6000-US has an internal power supply, requiring only a standard IEC power cable. There are no external power bricks or adapters needed.

Q: Is the L 6000-US compatible with future Sennheiser battery packs?

The modular dock design is future-proof. Sennheiser can introduce new charging modules for future battery types, which can be retrofitted into the existing L 6000-US base unit without replacing the entire station.
