Overview

What is the Sennheiser EW-DX 835-S SET?

The Sennheiser EW-DX 835-S SET is a two-channel digital wireless handheld microphone system with two EW-DX SKM-S transmitters, two MMD 835 cardioid dynamic capsules and one EW-DX EM 2 receiver. It delivers 1.9 ms latency, a 134 dB dynamic range and up to 12 hours per transmitter on the included BA 70 packs, which suits presenters, panel hosts and singers in UAE conference venues, ballrooms and places of worship.

The Sennheiser EW-DX 835-S SET is a ready-to-use Evolution Wireless Digital kit for two voices at the same time. Each EW-DX SKM-S handheld has a programmable mute switch and the Sennheiser standard capsule interface, so the head can be swapped for other Sennheiser or Neumann capsules. The half-rack EW-DX EM 2 receiver fits a 19 inch rack with the included GA 3 kit and can be managed over the network.

Why this product

Key Benefits

  • Two channels in one half-rack receiver

    The EW-DX EM 2 receives both handhelds, shows each link on an OLED display and runs on its 12 V adapter or on PoE (IEEE 802.3af).

  • Low-latency digital audio

    The Sennheiser Performance Audio Codec (SePAC) gives 1.9 ms system latency and a 134 dB dynamic range, so transmitter gain does not have to be set for each voice.

  • Dense, intermodulation-free frequency planning

    Up to 88 MHz switching bandwidth with equidistant spacing allows up to 146 channels at 600 kHz in Standard Mode, or 293 channels at 300 kHz in Link Density Mode.

  • Encrypted wireless link

    AES-256 encryption protects the audio link against eavesdropping in boardrooms and confidential meetings.

  • Rechargeable transmitters with an always-on display

    BA 70 lithium-ion packs run each handheld for up to 12 hours, the transmitters charge in the optional CHG 70N-C charger, and the E-Ink display keeps the settings visible even with the battery removed.

  • App and network control

    The Smart Assist App connects over Bluetooth Low Energy at up to 25 m, and Sennheiser Control Cockpit, Wireless System Manager or third-party control system plug-ins manage the receiver over Ethernet.

Use cases

Applications

  • Conferences and panel discussions

    Two handhelds let a moderator and a panellist, or a presenter and an audience microphone, run side by side on one receiver.

  • Hotel ballrooms and corporate events

    Each SKM-S transmits at 10 mW with a working range of up to 100 m, enough for large function rooms.

  • Places of worship and live vocals

    The cardioid MMD 835 capsule handles up to 154 dB SPL, so it works for speech and for singing close to the grille.

  • Training rooms and auditoriums

    Network control lets the AV team monitor battery and signal status from a control room instead of at the rack.

Expert FAQs

What pickup pattern does the Sennheiser EW-DX 835-S SET use?

The Sennheiser EW-DX 835-S SET uses the MMD 835, a dynamic capsule with a cardioid pickup pattern. It picks up the voice in front of the grille and rejects sound from behind, which helps against feedback from stage monitors. The capsule handles up to 154 dB SPL and has a sensitivity of 2.1 mV/Pa.

Which frequency range of this Sennheiser set should I order for the UAE?

The Sennheiser EW-DX 835-S SET is sold here in two frequency ranges: Q1-9 (470.2 to 550 MHz, article no. 509300) and R1-9 (520 to 607.8 MHz, article no. 509301). Sennheiser states that specific frequencies are subject to local RF regulations, and its International Frequency Advisor (SIFA) lists the ranges allowed per country, so confirm the range for your venue and match it with any receivers, boosters or splitters you already use.

How long does the handheld battery last?

Each SKM-S handheld in the Sennheiser EW-DX 835-S SET runs for up to 12 hours on a BA 70 lithium-ion pack, and two BA 70 packs are included. The handheld also accepts 2 AA 1.5 V batteries. It can charge inside the transmitter with the CHG 70N-C network-enabled charger, or the packs can charge on the L 70 USB charger, both sold separately.

What is the wireless range of the Sennheiser EW-DX 835-S SET?

The Sennheiser EW-DX 835-S SET has a working range of up to 100 m (328 ft), with each handheld transmitting at 10 mW ERP. For longer antenna runs Sennheiser offers the EW-D AB antenna boosters, for example EW-D AB (Q) for 470 to 550 MHz and EW-D AB (R) for 520 to 608 MHz. The Smart Assist App reaches the receiver over Bluetooth Low Energy at up to 25 m.

How many of these wireless channels can run in the same room?

Up to 146 Sennheiser EW-DX channels can run within the 88 MHz switching bandwidth in Standard Mode with 600 kHz spacing, or up to 293 channels in Link Density Mode with 300 kHz spacing. Each EW-DX EM 2 receiver handles 2 channels, and the AutoScan function assigns equidistant, intermodulation-free frequencies without manual RF planning.

What does the EM 2 receiver in this set connect to?

The Sennheiser EW-DX EM 2 receiver sends each wireless channel to a mixer, DSP or amplifier through its audio outputs, rated at 18 dBu max., and has a headphone output for monitoring. Its RJ-45 Ethernet port carries control for Sennheiser Control Cockpit and third-party systems such as Crestron and Q-SYS, and it can be powered over that cable with PoE (IEEE 802.3af) instead of the 11 to 13 V DC supply.

Can I change the capsule on the Sennheiser EW-DX 835-S SET handheld?

Yes, the handheld in the Sennheiser EW-DX 835-S SET takes other capsules. The SKM-S uses the Sennheiser standard capsule interface, so the MMD 835 can be replaced by modules such as the MMD 945-1 (supercardioid dynamic), MME 865-1 (supercardioid condenser), MMK 965-1 (switchable condenser) or the Neumann KK 204 and KK 205, sold separately.
