Unlike traditional analog wireless systems, the UWP-D supplements its proven analog UHF transmission technology with a proprietary digital audio processing. Transient sounds and consonants are reproduced with greater accuracy, resulting in clear, natural sound that’s intelligible and nuanced.

The ECM-V1BMP lavalier mic is optimized for capturing clear and intelligible speech. This omnidirectional mic picks up sound from every direction, allowing for a variety of placement options and freedom of movement.

Press and hold the NFC/Sync button on the receiver and it scans for the cleanest RF channel. Simply hold the transmitter next to the receiver; it automatically syncs up and you're good to go!

Unlike purely digital systems, the UTX-B40 allows you to send a single mic to multiple cameras for broadcast applications. Fast NFC communication makes setup for multiple receivers a breeze.

Auto-Gain mode saves you the time and aggravation of setting and managing the input level on the transmitter. It uses a limiter to help prevent distortion, great when the loudness of the presenter’s voice is unknown.

The +15 dB Gain Volume-Boost mode boosts the mic gain by 15 dB to compensate for situations when the mic is not close enough to the presenter’s mouth and the audio level is insufficient.

Manual input-level setting is also available.

The unit features an easy-to-read OLED display. The quick response of the display lets you see the operating conditions clearly and accurately in real time, even in bright sunlight.

Two levels of DSP filtering help remove the artifacts caused by occupancy sensors used in modern "green" buildings to turn off lights when people leave a room.

Two AA batteries (alkaline or NiMH rechargeable type) power the transmitter for up to 8 hours.

The unit can also be powered through its USB port, allowing it to run for numerous hours on a USB power pack or indefinitely, if you have access to AC.

A battery count-up timer allows for accurate reading of battery running time to minute accuracy.

• Switchable Mic/Line input level so you can set the correct gain level for your sound source.
• Low-cut filter reduces noise caused by wind or machinery—Off / Low (100 Hz) / Mid (150 Hz) / High (200 Hz).
• Simple menus make navigation easy. Advanced menus for in-depth control are also available.
• The variable mute button on the transmitter can be programmed for latched or momentary muting. It can also be used as a momentary talk button.
• You can operate up to 16 mics in one location.

The UWP-D transmitter can be used with a UWP Series or WL-800 Series receiver. A UWP Series or WL-800 Series transmitter can be used with a UWP-D receiver.

Q: 10. What is the best frequency band for the US West coast?

A: There is no one specific frequency band that is best for the US West Coast. The Sony UTX-P40 Wireless Plug-On Transmitters for the UC14 and UC25 bands each have 2,772 auto-scan frequencies within the band. This means that there are 2,772 individual frequencies that the wireless microphone system scans to automatically select the clearest one to use for transmitting audio. The UC90 band has 654 auto-scan frequencies within the band. The UTX-P40 Transmitter will need to be used with a compatible Sony wireless microphone receiver that operates on the same frequency band.
