The BLX series beltpack transmitter works with lavalier and headset microphones, and also with the WB98H microphone, designed especially for horns. It is designed to withstand the high sound pressure level at the bell of a saxophone, trombone or trumpet. This package comes with the WB98H mic, along with the mounting clip to hold the microphone to your horn.

It is a premium cardioid condenser instrumental microphone that clamps onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the microphone to be easily positioned and secured in place, and an isolation shock-mount reduces the transmission of instrument 'key noise' and other mechanical noise. A gooseneck angle brace is included to provide better retention of the microphone placement during more active performances.

The beltpack transmitter features an On/Off hard toggle switch, preferring to eliminate the multi-function push button that is used on some wireless transmitters. Many users found the multi-function single button to be inconvenient and unreliable.

This package includes the BLX beltpack transmitter and the WB98H microphone and mounting hardware, along with the BLX4 receiver. The BLX4R receiver is packaged in a lightweight, durable metal chassis and can be mounted in any 19-1/2" rack. It comes with all necessary mounting hardware. It has a smaller footprint than previous receivers, and features an enhanced group and channel scan. Up to 12 compatible systems per frequency band (region dependent). It features microprocessor-controlled internal antenna diversity, one-touch QuickScan frequency selection quickly locates the best frequency, 1/4" and XLR audio outputs, and two color audio status indicator LED.
