Sennheiser EW-D SK BASE SET (Y1-3), Receiver, Bodypack Transmitter, Without Lapel, 1785.2-1799.8MHz

Sennheiser EW-D SK BASE SET (Y1-3) Digital Wireless Base System

The Sennheiser EW-D SK BASE SET Y1-3 (Article Number: 508749) is a professional, single-channel digital UHF wireless foundational package. This specific "Base Set" configuration bundles a stationary rackmount receiver and a rugged bodypack transmitter, deliberately omitting a lapel or headset microphone. This allows front-of-house engineers and media integration specialists to choose the exact lavalier, headworn mic, or instrument interface cable that best fits their application.

This system operates in the Y1-3 frequency band (1785.200 MHz to 1799.800 MHz). This upper-spectrum allocation provides a reliable solution in regions with highly congested lower UHF TV channels (470–608 MHz), moving your audio link into a dedicated, low-interference frequency pocket.

Key System Performance and Integration Attributes

• Equidistant Tuning Grid Precision: Borrowing tech from Sennheiser’s flagship Digital 6000/9000 systems, the EW-D platform features linear transmitter performance that completely eliminates intermodulation distortion. This permits an equidistant channel frequency layout spaced exactly 600 kHz apart, maximizing frequency coordination without complex math.

• 134 dB Input Dynamic Range: The bodypack transmitter features an ultra-wide analog input dynamic scale. This completely removes the need for traditional transmitter sensitivity/gain adjustment menus; the hardware handles whispering presenters and high-output electric guitar transients simultaneously without clipping.

• Bluetooth Low Energy (BLE) Smart Assist App App integration: Mobile crews can configure, label, coordinate, and scan the entire wireless setup remotely using an iOS or Android smartphone via Bluetooth. It allows real-time battery status monitoring, muting overrides, and instant sync pairing directly from the screen.

• Ultra-Low Latency: Clocking in at a near-imperceptible 1.9 milliseconds of total system digital latency, the audio path maintains impeccable timing for live stage vocalists, musical theater leads, and active monitoring applications.

System Deployment and Hardware Interfacing Advice

Locking the Input Pin Configuration: The EW-D SK bodypack uses a 3.5 mm locking TRS input jack. When plugging in a third-party or older Sennheiser Evolution lavalier (like an ME 2-II or MKE 2), always thread the connector's metal collar firmly into the bodypack's chassis socket. This secures the connection against clothing tugs and prevents static discharge pops or connection dropouts.

Mind the Y-Band Antenna Physics: Because the 1.7 GHz frequency band uses short radio wavelengths, maintaining a clear line-of-sight between the receiver's rod antennas and the bodypack is critical. Avoid hiding the receiver inside metal equipment cabinets. If you are mounting the receiver inside a deep metal audio rack, use the included GA 3 Rackmount Kit extension cables to mount the antennas cleanly onto the front faceplate for the best possible line-of-sight reception.
