Sennheiser EM 9046 DAO AF output module, digital, AES3, 44.1-96 kHz, 24-bit, outputs to 8x XLR-3M and 1x 25-pin sub D - 502511

Product Overview

The Sennheiser EM 9046 DAO is an AES3 digital audio output module for the Digital 9000 EM 9046 four-slot mainframe receiver system. It provides eight channels of balanced AES3 digital audio via XLR-3M connectors plus a single 25-pin sub-D multicore output for direct console integration. Supporting sample rates from 44.1 kHz through 96 kHz at 24-bit resolution, the DAO module suits broadcast studios, theatres, and auditoriums where digital audio distribution and console routing flexibility are critical. Up to six analog or digital output modules can be installed in a single EM 9046 mainframe, enabling flexible signal splitting for complex system architectures.

Product Description

The EM 9046 DAO is a plug-in output module that installs into one of the four available slots in the Sennheiser EM 9046 mainframe — the multichannel receiver at the core of the Digital 9000 professional wireless platform. The module converts received wireless audio to AES3 digital format, delivering eight discrete channels simultaneously via individual XLR-3M male balanced connectors and mirroring all eight channels on a single 25-pin sub-D multicore connector, commonly used for direct multitrack console connections. This dual-output architecture allows simultaneous feed to both a digital audio distribution system and a mixing console without additional splitters or conversion hardware. Sample rate selection covers 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz, all at 24-bit word length, meeting the requirements of high-resolution broadcast and studio workflows. Audio routing is configurable via software, giving engineers control over signal assignment across the mainframe's channel complement. The EM 9046 mainframe supports up to eight receiving channels and covers the UHF spectrum from 470 to 798 MHz, with a built-in graphical spectrum analyzer and RF level recorder for real-time frequency management. The DAO module is interchangeable with other EM 9046 output modules, including the analog AF module and Dante network output module, making it straightforward to upgrade or reconfigure the system as infrastructure requirements evolve. AES3 output ensures bit-perfect audio delivery with no analog conversion losses in the signal chain.

Frequently Asked Questions

Q: Is the EM 9046 DAO a standalone product, or does it require additional hardware?

The EM 9046 DAO is a plug-in output module and requires the Sennheiser EM 9046 mainframe to operate. The mainframe chassis is sold separately and accommodates up to four receiving channel modules plus up to six output modules.

Q: How many output modules can be installed in a single EM 9046 mainframe?

The EM 9046 mainframe supports a signal split of up to 1:6, meaning up to six output modules — DAO, analog AF, or Dante — can be installed simultaneously, distributing audio to multiple destinations from one receiver.

Q: What is the difference between the DAO module and the DAN (Dante) module?

The DAO module outputs AES3 digital audio over XLR-3M and 25-pin sub-D connectors for direct console or patchbay integration. The DAN module outputs audio over a standard Ethernet network using the Dante protocol for IP-based audio distribution. Both modules install in the same EM 9046 slot and can coexist in the same mainframe.

Q: Does the DAO module support 48 kHz operation for broadcast?

Yes. The EM 9046 DAO supports 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz at 24-bit. 48 kHz is the standard sample rate for broadcast workflows and is fully supported.

Q: Can audio routing be changed after installation?

Yes. Audio routing across the EM 9046 output modules is configurable via Sennheiser Wireless Systems Manager (WSM) software, allowing signal assignment to be adjusted without hardware changes.

Q: Which wireless transmitters are compatible with the EM 9046 system?

The EM 9046 mainframe is compatible with Sennheiser Digital 9000 series transmitters (SKM 9000, SK 9000) and, in Long Range mode, with the Digital 6000 SKM 6000 and SK 6000 transmitters.

Q: Does the 25-pin sub-D output carry all 8 channels simultaneously?

Yes. The 25-pin sub-D connector carries all eight AES3 channels as a multicore output, providing a single-cable connection to compatible mixing consoles and audio distribution systems.

Q: Is software or a driver required to use the DAO module?

No driver is required for basic AES3 output — the module functions as a standard AES3 source on connection. Sennheiser Wireless Systems Manager (WSM) software is optional but recommended for audio routing configuration and system management.
