Sennheiser EW-D SKM-S BASE SET Digital Wireless Handheld Microphone System, No Mic Capsule (R1-6: 520 to 576 MHz)

• With a remarkable 134 dB dynamic range on the transmitter, the days of worrying about overloading your signal are over. The EW-D can handle a wide variety of sound sources, including loud vocalists and performers, all without requiring any gain adjustment at the transmitter.
• The ultrawide dynamic range yields impressive signal-to-noise performance and accurate transient response, which bring out all the nuances of your sound.
• With 24-bit digital audio and a flat 20 Hz to 20 kHz frequency response, the EW-D delivers clear, accurate audio reproduction.
• The system's ultralow 1.9ms latency is practically undetectable, helping vocalists to stay in the groove when performing live.

• The transmitter's interchangeable capsule design allows you to use a variety of dynamic and condenser mic capsules, with pickup patterns ranging from wide omnidirectional to narrow supercardioid—capsules include the MMD 845, MME 865, MMD 935, MMD 945, MMD 42, MM 435, ME 9004, MD 5235, ME 5004, and Neuman KK204 to name a few.
• The rugged, all-metal transmitter is equipped with a mute button that can be locked out and overridden from the receiver or a mobile device during a performance.
• The transmitter quickly pairs with the receiver via Bluetooth at a distance up to 120', at the press of a button.

• The EW-D EM receiver offers intuitive front-panel controls and a high-contrast OLED with meters for RF, battery status of the associated transmitter, and audio output that make setup a breeze.
• The auto-scan function automatically seeks out the cleanest available frequency for you.
• The back panel houses a balanced XLR output and an unbalanced 1/4" output for direct connection to any PA system or mixing board.
• The two detachable 1/4-wave dipole antennas on the back of the unit can be upgraded for improved RF performance.
• The unit comes with a kit for rackmount installation and a universal power supply with EU, US, and UK adapters.

• The EW-D features an equidistant tuning grid that equally spaces 2240 frequencies across the wide 56 MHz bandwidth to prevent disruptive intermodulation issues that occur when multiple transmitters operate in confined spaces.
• The equidistant grid also enables you to maximize your channel count and operate up to 90 mic channels simultaneously without having to worry about frequency coordination and channel groups—making your setup even easier, even in congested RF environments.
• The EW-D uses Intelligent Switching Diversity technology to mount a superior defense against multipath and other anomalies that cause RF noise. The system compares incoming signals on two independent antennas and receiver circuits to ensure optimal wireless quality. The receiver switches between antennas only during header data as to never affect the audio information.
• The EW-D operates in the UHF band, far away from potential Wi-Fi interference in the 2.4 GHz band.

• With the Smart Assist App (free download available separately) installed on your Android/iOS phone/tablet, the power of Bluetooth Low Energy connectivity puts full control of the EW-D right in the palm of your hand. Use your mobile device to connect via Bluetooth for efficient operation and monitoring of your system—with no wireless expertise required.
• Take advantage of a remarkably fast automated set up of receivers and transmitters, automatic and manual frequency allocation, muting, battery status, and channel naming to help keep systems organized—all only one tap away.
• Aside from instant access to all system settings, there is also a support hub with video tutorials and detailed manuals to help get you started.
• When working with multiple systems, the App provides access to all system settings, centralizing control and eliminating the need for complicated menu navigation on each device. Wireless channel naming helps to keep systems organized.
• Up to 16 mic channels can be handled remotely via a single mobile device. Additional channels can be controlled via additional phone/tablets with a maximum of 16 channels per device. 
• If your phone is not available, you can fully operate your system using the buttons on the receiver.

• The rear-mounted, 1/4-wave detachable antennas can be upgraded to longer, 1/2-wave dipole antennas (available separately) for added range and reliability.
• Antennas may not perform optimally when rear-mounted inside a metal equipment rack. Using the AM 2 antenna front-mount kit (available separately) gives you the option to mount the two antennas on the front of your rack, maintaining line-of-sight between the receiving and transmitting antennas for even greater connection reliability—this option is available only when mounting just one EW-D EM receiver per 1 RU rackspace.
• Adding the ADP UHF passive/directional remote antennas (available separately) to your system enables you to position the antennas closer to your transmitter and orient them for maximum coverage, achieving professional-quality RF signal reliability with virtually no dropouts.
• For larger, multi-receiver systems, the EW-D ASA active antenna splitter (available separately) splits the signals from the two antennas (now connected to its rear panel), delivering the RF signals to up to four receivers in a rack. The Unit also provides DC power to the four receivers, for less clutter in your rack.

Presenters/Clergy/Lecturers/Educators:

• The sweat-resistant, subminiature MKE 2 omnidirectional lavalier mic offers a pristine, broadcast-quality sound and is easy to conceal.
• The unobtrusive ME 2 omnidirectional lavalier mic provides a forgiving pickup pattern that captures sound equally well in every direction. 
• The ME 4 cardioid lavalier mic cardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
• The ME 3 cardioid headset mic provides enhanced speech clarity for lectures and presentations.

Guitarists/Keyboardists:

• The CI 1 instrument cable lets you connect the bodypack transmitter to a guitar, bass, or keyboard.
