BST PWA-BROADCAST-TX - UHF Transmission Module for PWA220 / PWA320

BST PWA-BROADCAST-TX - UHF Transmission Module for PWA220 / PWA320

The BST PWA-BROADCAST-TX UHF transmission module allows you to duplicate the master signal of your PWA220 or PWA320 portable PA system to a second slave device (another PWA220/PWA320) or to a PWA200-SL receiver module. Designed for professional and mobile environments, it connects directly to the LINK port of the active loudspeaker and transmits the high-quality audio signal wirelessly. Installation is plug-and-play: simply set the selector to TX mode, adjust the link volume, and turn on the module to synchronize transmission. Compact and lightweight, it is ideal for expanding coverage at events, outdoor conferences, or modular installations without sacrificing flexibility and speed of installation.

Main features

• Compatible with PWA220 and PWA320 active speakers
• TX operating mode: UHF transmitter of the master signal

Product benefits

• Unlimited scalability: Add as many slave speakers as you need to cover large spaces.
• Maintaining sound quality: Transmits the audio signal wirelessly without perceptible interference.
• Mobility and speed: Set it up and running in seconds, ideal for touring and mobile installations.
• Perfect integration: It is powered by the main speaker and occupies the same LINK port, without modifying the equipment.
• Professional reliability: Robust UHF prevents signal loss and minimizes latency.

Use cases

• Extending sound coverage at outdoor events or large venues.
• Creating independent zones with multiple slave speakers in conferences.
• Implementation of modular systems for traveling presentations.
• Signal reinforcement in temporary installations where cabling is not feasible.

Frequently Asked Questions

• Do you need additional power?
  No, it is powered directly from the main speaker when connected to the LINK.
• How do I activate streaming mode?
  Move the internal selector to the TX position and adjust the level with the link volume control.
• How many slaves can I link?
  You can cascade up to 4 slave modules to cover larger areas.
• Does it require manual synchronization?
  No, when you turn on the TX module on the master and set the slave to RX, they automatically link.
