What to know before buying

The J11 frequency band is subject to local authorization. Confirm compliance in your area before ordering.
The stated 300 ft range is line-of-sight, and the up-to-14-hour battery claim applies to each BLX2 under typical conditions.

Listing details to confirm

The listing is inconsistent about the package: its title and feature text specify a BLX88 receiver and two BLX2 handheld transmitters, while the included-components and built-in-media fields name a BLX1 bodypack transmitter. Confirm the selected listing's exact kit before purchase. The listing labels the wireless connection as XLR even though it describes an RF system. Treat XLR as an unconfirmed connection detail and confirm the receiver output and required connections for your audio setup.

Frequently asked questions

Can two microphones be used with this system?

The listing describes a BLX88 dual-channel receiver and two BLX2 handheld transmitters, so it is presented as a two-microphone setup. Confirm the selected package because other listing fields name a BLX1 bodypack transmitter.

What is the claimed operating range?

The listing claims up to 300 ft (100 m) line-of-sight. It does not establish that distance in every environment.

How long do the transmitters run on batteries?

The listing claims up to 14 hours for each BLX2 handheld transmitter using AA batteries under typical conditions.

Can I use the J11 band in Canada?

The supplied listing says to verify local authorization for the J11 (596–620 MHz) spectrum. Confirm current local requirements before ordering.
