Instrument wireless system from BLX series that combines professional-quality sound with simple setup and an intuitive interface for legendary audio performance right out of the box, containing a rack-mount receiver BLX4R, a body-pack transmitter BLX1 and a BETA98H/C instrument microphone. Rack-mountable and featuring rugged metal construction, the receiver offers simple setup and intuitive controls. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference, while removable antennas allow for quick antenna distribution. It provides XLR and 6.3mm output connectors with adjustable output level, an LCD screen with detailed RF and audio metering and a two-colour audio status indicator LED. The body-pack transmitter features power and battery status LED, an adjustable gain control and quick and easy frequency matching. It is powered by AA batteries (included) that provide up to 14 hours of continuous use. The premium condenser instrument microphones clamps onto the bell of wind instruments or onto the rim of percussion instruments. It features transformerless preamplifier circuitry which improves linearity across the full frequency range and its cardioid pickup pattern provides high gain-before-feedback and excellent rejection of unwanted noise. Its high maximum sound pressure level (SPL) enables it to handle the extreme demands of brass, woodwind and percussion instruments. The microphone’s integrated gooseneck and ratcheting swivel joint allows it 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. The microphone features a 3m high-flex cable with attached preamplifier (XLR connection). The system provides a 100m operating range under typical conditions and comes supplied with single and dual rack-mount kit, two 1/4 wave antennas, a zipper bag, a power supply and two AA batteries. Frequency: 606-630 MHz
