Sony UWP-D Dual Wireless Set – Freq. Range 33-40

  • Dual receiver and 2x transmitter set
  • Digital companding circuitry
  • Automatic channel scanning
  • Integrated 3-channel mixer at receiver
  • Selectable mic/line input at transmitter
  • Adjustable attenuator
  • Simultaneous multi-channel operation
  • UWP and WL-800 series compatibility


The Sony UWP-D Dual Wireless Set – Freq. Range 33-40 offers wide frequency coverage with up to 72 MHz bandwidth across a broad range of channels. Its integrated 3-channel mixer allows you to control your levels as well as assign outputs freely. The URX-P03D receiver can be mounted directly (without cables) onto many Sony cameras that have an MI (Multi-Interface) Shoe by using the optional SMAD-P3D two-channel shoe adapter.

We’ve completed this set with a Hirose to AA dummy adapter, to give you the ability to power the receiver independently in your sound mixer bag.

Wireless Features

With its Clear Channel Scan, Active Channel Scan function, and IR Sync features, the system detects unoccupied channels and selects the most appropriate channel automatically for fast- and-easy system setup.

The Auto Set channel mode allows the user to find and set available frequencies to use within the operating frequencies of the system. The receiver will automatically set the transmitter channel using the IR Sync feature. The extra-wide switching bandwidth covers a large area, with a wide choice of channels available across multiple models.

This system achieves an exceptionally stable audio signal being delivered from two independent receiver sections within the unit. Optimum signal quality is delivered by the two receivers sections, and a comparison circuit constantly pulls the one with the best signal to give dropout-free transmission.


The UWP-D system provides its own headphone output socket, which is particularly useful when working with a camera that does not have a headphone output. Furthermore, it provides variable output level control of ±12 dB, for use with the various input levels of camcorders and DSLR cameras.
