Bosch Handheld Wireless System with PL22 Dynamic Microphone (R300-HD/B)

14 hours of battery life on two AA batteries, and a single button to find the cleanest channel out of 32. The cardioid head rejects room noise and limits the risk of feedback on stage.

  • UHF wireless link, 32 preset channels
  • ClearScan: automatic search for the clearest channel at the touch of a button
  • EZsync: channel transfer by infrared from the receiver to the transmitter
  • 14 h of battery life with two AA alkaline batteries
  • Dual-antenna receiver to avoid signal loss
  • Metal handheld transmitter, backlit LCD screen with battery gauge
  • Metal receiver chassis, 19-inch rack mounting possible
  • Balanced and unbalanced outputs on the receiver
  • For singing, conferences and hosting

Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Staging : microphone stand, boom arm, pop filter, mounts and ambient speakers photographed are not included unless stated.
  • Quantity : the number of speakers or channels visible in the image does not necessarily match the set sold.
  • Cables and tips : the cables, adapters, ear tips and cases supplied are those listed in the specifications.
  • Specifications : Bluetooth, jack socket, USB, noise cancellation and battery life cannot be read from a photo.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.
