Product Overview
The SLXD14/B98H features the BETA98H/C miniature instrument microphone and the SLXD1 transmitter. It provides transparent digital audio and rock-solid RF stability for lecture halls and live performances.
The SLXD14 Wireless System delivers transparent, 24-bit digital audio and rock-solid RF performance for a wide range of applications, from day-long presentations to nighttime performances. Operate up to 32 compatible systems per 44 MHz band, with easy setup and optional rechargeability accessories for wireless excellence, wherever required. Ships with SLXD4 single-channel receiver, SLXD1 bodypack transmitters and BETA 98H/C miniature cardioid condenser instrument microphone with antenna, rackmount accessories and 2 AA batteries.
The BETA®98H/C is a premium cardioid condenser instrument 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 mic to be easily positioned and secured, 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.
