Audibax Sidney 1250 B - Dual UHF Wireless System with 2 Handheld Microphones (Frequency B 570.3–640.7 MHz)

Audibax Sidney 1250 B - Dual UHF Wireless System with 2 Handheld Microphones (Frequency B 570.3–640.7 MHz)

The Audibax Sidney 1250 B is a dual UHF wireless microphone system that includes two handheld microphones with cardioid dynamic capsules and a dual receiver with RF/AF displays and indicators. Designed for live performances, corporate events, educational institutions, and rental/installation, it combines diversity antennas for stable pickup, independent volume control per channel, and a clear audio path with a frequency response of 40 Hz–18 kHz , a signal-to-noise ratio >103 dB (1 kHz), and distortion <0.5% . It operates in the B frequency band (570.3–640.7 MHz) with ±0.0005% stability and RF power <10 mW , offering an approximate range of 80 m . The receiver features two balanced XLR outputs (one per channel) and one 6.35 mm mixed output jack for sending a combined stereo/mono mix if required. Each microphone is powered by AA batteries with an approximate autonomy of 8 hours and has an on/off switch and a display with low battery warning.
