Sennheiser SK 2000 Bodypack Transmitter

Product Overview

The Sennheiser SK 2000 is a professional-grade bodypack transmitter from the Evolution Wireless 2000 series, built for demanding live performance, broadcast, and installation applications where audio reliability and transmission flexibility are critical. It offers four selectable RF output power levels— 10, 30, 50, and 100 mW—enabling operators to balance transmission range and channel density based on the specific venue and RF environment. The transmitter covers up to 72 MHz of switching bandwidth and supports 26 fixed frequency banks with up to 64 compatible presets per bank, providing extensive frequency coordination options across a wide range of operating conditions. With all-metal housing, HiDyn+ compander technology, and deep integration with the Evolution Wireless 2000 receiver ecosystem, the SK 2000 is a trusted choice for theatrical productions, broadcast studios, and touring live sound systems.

Product Description

The SK 2000 bodypack transmitter is engineered for professionals who need maximum control over every aspect of their wireless audio chain. The four RF output power settings— 10, 30, 50, and 100 mW—allow the system to be tuned for close-range studio work, mid-size theatrical stages, or large outdoor broadcast environments without requiring additional hardware. Input sensitivity can be adjusted in 3 dB steps for gains above 60 dB, providing precise level matching for instruments ranging from bass guitars to condenser lavalier microphones. An enhanced bass frequency response makes the SK 2000 especially well-suited to bass guitar applications, where low-end clarity and headroom are critical. The 26 factory frequency banks each store up to 64 compatible frequency presets, and the 25 kHz tuning step resolution allows fine-grained frequency coordination in congested RF environments. Pilot tone squelch suppresses noise and interference during signal dropout events, ensuring clean muting rather than audio artifacts reaching the PA system or broadcast feed. The backlit display activates on keystroke for discreet use in dark performance environments, while the auto-lock feature prevents accidental button presses during active performances. An infrared interface allows the transmitter to be synchronized directly from the paired EM 2000 receiver, eliminating manual frequency entry on the transmitter body. For installations using optional rechargeable batteries, external charging contacts on the transmitter body allow in-unit charging without removing the BA 2015 battery pack. The Sennheiser Control Cockpit software provides centralized management, monitoring, and configuration of all networked Evolution Wireless 2000 devices from a single computer interface.

Frequently Asked Questions

Q: Which receiver is the SK 2000 designed to work with?

The SK 2000 is designed for use with the Sennheiser EM 2000 receiver, which is part of the Evolution Wireless 2000 series. It can also be integrated into multi-channel installations using compatible EW 2000 series rack receivers.

Q: What are the four RF output power options, and when should each be used?

The SK 2000 offers 10, 30, 50, and 100 mW output settings. The 10 mW setting is appropriate for close-range applications or channel-dense environments where minimizing interference is critical. Higher power settings— 50 or 100 mW—are used for larger stages or outdoor venues requiring extended transmission range.

Q: Can the SK 2000 transmitter be configured from the receiver?

Yes. The transmitter can be configured remotely from the EM 2000 receiver menu, and frequency synchronization is performed via an infrared interface by pointing the transmitter at the receiver, eliminating manual frequency entry on the transmitter body.

Q: Is a rechargeable battery option available?

Yes. The SK 2000 supports the optional Sennheiser BA 2015 rechargeable battery pack. The transmitter includes external charging contacts that allow the battery to be charged while it remains inside the unit, without requiring battery removal.

Q: Why does the SK 2000 have enhanced bass frequency response?

Sennheiser specifically engineered the SK 2000 with an optimized bass frequency response for instruments such as bass guitars, where low-frequency clarity and headroom are important. This makes it a preferred transmitter for musicians who play bass instruments in live and studio settings.

Q: What is pilot tone squelch, and why does it matter?

Pilot tone squelch is a signal-muting mechanism that activates when the receiver loses contact with the transmitter. Instead of passing RF interference noise to the audio output, the squelch circuit cleanly mutes the output until the signal is re-established, preventing disruptive noise bursts during a live performance or broadcast.

Q: How does the auto-lock feature work?

The auto-lock feature locks the transmitter's buttons after a configurable period of inactivity, preventing accidental frequency or level changes caused by body movement, clothing contact, or inadvertent presses during a performance. The lock can be deactivated by holding the appropriate button combination.

Q: What management software is available for the SK 2000?

Sennheiser offers the free Control Cockpit software, which provides a centralized interface for monitoring, configuring, and managing all networked Evolution Wireless 2000 series devices from a computer. It displays real-time status information for all connected units and simplifies large-system administration.
