Sennheiser EM 6000 2-Channel Digital Wireless Receiver w/ True Bit Diversity and AES-256 Encryption (470 - 714MHz) - 506657 - 506657

Product Overview

The Sennheiser EM 6000 is a two-channel rack-mount digital wireless receiver from the Digital 6000 series, designed for professional live production, broadcast, and large-venue installations. It delivers intermodulation-free digital transmission with AES-256 encryption and True Bit Diversity in a compact 1 RU form factor, making it a reliable 2-channel digital wireless receiver for demanding RF environments. Unlike the EM 6000 Dante variant, this model provides full analog and AES-3 digital connectivity without a Dante network card, offering a straightforward choice for facilities running conventional analog or AES infrastructure.

Product Description

The EM 6000 houses two independent receiver channels in a single 19-inch rack unit, each with a dedicated high-contrast OLED display. The Digital 6000 platform's equidistant frequency grid prevents intermodulation products from forming between transmitters, allowing up to 20 active transmitters to operate within a single 6 MHz TV channel without coordination penalty. This is a practical operational advantage on stages or broadcast floors where large channel counts are the norm.

True Bit Diversity reception evaluates the quality of each individual bit across two parallel reception paths and recombines the optimal bits in real time. This provides a more granular dropout defense than conventional dual-antenna diversity switching, keeping audio clean through multipath-heavy environments such as arena floors, theater stages, and reverberant houses of worship. Error correction and audio error masking further address RF problems before they reach the audio output.

The 244 MHz switching bandwidth — covering 470–714 MHz — gives engineers extensive spectrum to work with when coordinating large channel counts or avoiding local interference. Thirty-two RF pre-selection filters at the antenna input suppress out-of-band interference before it can affect the receiver stages. The integrated active antenna splitter allows up to eight EM 6000 units to be cascaded from a single antenna pair, eliminating external antenna distribution hardware for installations of up to 16 receiver channels.

Audio outputs include transformer-balanced analog XLR and 6.3 mm jack connectors, a digital AES-3 output with word clock I/O, and a headphone monitoring output. The receiver supports Long Range mode with the SeDAC codec for maximum transmission range, and Link Density mode with the SePAC codec for high-density channel configurations of up to five channels per MHz. Automatic frequency setup scans and distributes frequencies to all connected units from the receiver front panel. Full remote monitoring and configuration is available via Sennheiser's Wireless Systems Manager (WSM) software. Compatible transmitters include the SK 6000 bodypack, SK 6212 miniature bodypack, SKM 6000 handheld, as well as SK 9000 and SKM 9000 transmitters operating in Long Range mode. For facilities requiring Dante network audio, the EM 6000 Dante variant adds Brooklyn II-based Dante connectivity at a higher price point.

Technical Specifications

Frequently Asked Questions

Q: Which transmitters are compatible with the EM 6000?

The EM 6000 is compatible with the SK 6000 bodypack, SK 6212 miniature bodypack, and SKM 6000 handheld transmitter in standard modes. In Long Range mode, it also works with the SK 9000 bodypack and SKM 9000 handheld from the Digital 9000 series.

Q: What is the difference between the EM 6000 and the EM 6000 Dante?

The EM 6000 Dante adds an Audinate Brooklyn II card with two Amphenol RJ-45 Dante network ports, allowing the receiver to route audio over a Dante IP network. The standard EM 6000 provides the same RF performance and outputs but without Dante connectivity, at a lower price point. If your facility uses Dante, the EM 6000 Dante is the appropriate choice.

Q: How many channels can be run from one antenna pair?

The integrated active antenna splitter supports cascading up to eight EM 6000 units from a single antenna pair — 16 individual receiver channels — without any additional distribution hardware.

Q: What is True Bit Diversity and how does it differ from standard RF diversity?

Standard RF diversity switches between two complete antenna signals based on signal strength. True Bit Diversity works at a more granular level, evaluating each individual bit from two parallel reception paths and selecting the best bit. This makes it more effective at catching errors that occur between conventional switching thresholds.

Q: Does the EM 6000 support AES-256 encryption?

Yes. AES-256 encryption is built in and transparent during operation, applicable whenever compatible encrypted transmitters are used. This is standard for the EM 6000 platform regardless of operating mode.

Q: Can I remotely control the EM 6000?

Yes. The EM 6000 integrates with Sennheiser's Wireless Systems Manager (WSM) software for full remote monitoring, frequency coordination, and configuration of multiple units from a central workstation.

Q: What is the difference between LR mode and LD mode?

Long Range (LR) mode prioritizes transmission range and reliability using the SeDAC codec. Link Density (LD) mode prioritizes spectral efficiency using the SePAC codec, enabling up to five channels per MHz of bandwidth for high-density installations.

Q: What warranty does the EM 6000 carry?

The EM 6000 carries a standard 2-year Sennheiser limited warranty against manufacturing defects. Contact Creation Networks at creationnetworks.net for warranty support or service inquiries.
