Sennheiser EW-DX TS 3-PIN Digital Wireless Tablestand Transmitter with 3-Pin XLR Connector, No Mic

Product Overview

The Sennheiser EW-DX TS 3-PIN is a digital wireless tablestand transmitter designed to pair with EW-DX series receivers, accepting a 3-pin XLR input for use with standard dynamic and electret gooseneck microphones. It delivers 24-bit digital audio with 134 dB of input dynamic range and AES 256-bit encryption across a wide 80 MHz tunable bandwidth. The metal-housed transmitter is built for boardrooms, council chambers, podiums, and conference tables where a clean, cableless microphone footprint is required. It is backward-compatible with EW-D receivers, protecting integration investments in mixed-generation installations.

Product Description

The EW-DX TS 3-PIN accepts a 3-pin XLR female input, making it the correct tablestand choice for gooseneck microphones terminated with a standard 3-pin XLR connector. Note that the 3-pin configuration does not supply phantom power — the transmitter is intended for use with microphones that draw bias/plug-in power or are self-powered, such as dynamic capsules. This is the key distinction from the 5-pin variant, which supports a wider range of XLR gooseneck configurations.

The transmitter operates on an equidistant tuning grid that spaces 3,200 selectable frequencies evenly across an 80 MHz bandwidth. This approach eliminates the intermodulation products that arise when multiple transmitters operate in close proximity, allowing dense multi-channel deployments. In standard equidistant grid mode the system supports up to 134 simultaneous channels, expandable to 269 channels in Link Density mode for large conference and broadcast environments.

System setup is handled via Bluetooth 5.1 LE, pairing the transmitter with a receiver or a mobile device running the Sennheiser Smart Assist app for iOS and Android. The programmable mute button supports momentary, Push-to-Talk, or Push-to-Mute operation, with a bicolor LED indicating active mute status. The button can be locked or overridden remotely from the receiver during a session, ensuring moderator control in multi-participant meetings. A fully charged BA 40 lithium-ion rechargeable battery pack (included) delivers up to 11 hours of runtime. When not in use, the transmitter can be placed on the CHG 2W inductive charging station (sold separately) for hands-free, cable-free recharging.

Technical Specifications

Frequently Asked Questions

Q: What is the difference between the EW-DX TS 3-PIN and the EW-DX TS 5-PIN?

The 3-pin variant uses a standard 3-pin XLR female input and does not supply phantom power. The 5-pin variant uses a 5-pin XLR input, which supports a broader range of Sennheiser gooseneck microphones including those requiring phantom power. Choose the 3-pin model for dynamic or bias-powered gooseneck capsules with standard 3-pin XLR connectors.

Q: Does this transmitter include a gooseneck microphone?

No. The EW-DX TS 3-PIN is sold as a transmitter only, without a gooseneck microphone. A compatible Sennheiser 3-pin XLR gooseneck microphone is required and must be purchased separately.

Q: Which receivers is this transmitter compatible with?

The EW-DX TS 3-PIN is designed for use with EW-DX series receivers. It is also backward-compatible with EW-D receivers for use in mixed-generation installations.

Q: How does the mute button work?

The mute button is programmable and can be set for Momentary, Push-to-Talk, or Push-to-Mute operation. A bicolor LED displays the current mute status. The button can be locked or overridden remotely from the EW-DX receiver by a moderator.

Q: How is the transmitter charged?

The included BA 40 battery pack is charged inductively when the transmitter is placed on the CHG 2W Wireless Power Transmitter (sold separately). No cable connection is required for charging.

Q: How many simultaneous channels can the EW-DX system support?

In standard equidistant tuning grid mode, up to 134 simultaneous channels are supported. In Link Density mode, the system can accommodate up to 269 channels, making it suitable for large conference centers and broadcast facilities.

Q: Can I manage this transmitter remotely?

Yes. The EW-DX TS 3-PIN connects via Bluetooth 5.1 LE to EW-DX receivers and to the Sennheiser Smart Assist app for iOS and Android, enabling remote monitoring, setup, and mute control from a mobile device or receiver interface.

Q: What is the system latency?

The EW-DX system operates at 1.9 ms latency, which is transparent in live speech reinforcement and broadcast applications.
