Audibax Sidney 500 A - Dual Handheld UHF Wireless System with Carrying Case (516–558 MHz)

Audibax Sidney 500 A - Dual Handheld UHF Wireless System with Carrying Case (516–558 MHz)

The Audibax Sidney 500 A is a dual-handheld UHF wireless microphone system designed for events, conferences, education, churches, and live performances. It operates in the A-band (516–558 MHz) and offers stable transmission with a signal-to-noise ratio > 100 dB , dynamic range > 100 dB , frequency stability ±0.03% , and distortion ≤ 0.02% . It includes two handheld microphones with unidirectional dynamic capsules and a receiver with independent balanced XLR outputs for each channel and a 6.3 mm mixed output jack . Typical coverage is up to 50 m line-of-sight , with a specified frequency response of 40 Hz–16 kHz . Each transmitter is powered by two AA (1.5 V) batteries and provides up to 10–12 hours of battery life; the receiver is powered by 12–15 V DC via a 100–240 V AC adapter. It comes with a carrying case for safe handling and storage.

Frequently Asked Questions

• How many microphones are included? Two handheld microphones and a dual-channel receiver.
• How do I connect the system to my equipment? Use the balanced XLR outputs to send each channel to a separate mixer/interface input, or the 6.3 mm mixed jack output for a single stereo/mono input.
• Can I use multiple systems at the same time? Yes, it is possible to operate multiple systems within the band if the frequencies are planned to avoid overlaps and local spectrum regulations are respected.
• What is the battery life of the microphones? Approximately 10–12 hours per microphone with new AA alkaline batteries.

Connections and power supply

• Receiver: 2 × balanced XLR outputs, 1 × 6.3 mm mixed output, DC 12–15 V power input (includes AC 100–240 V adapter).
• Handheld transmitters: powered by 2 × AA (1.5 V) each; RF power 5 mW .

Usage recommendations

• Place the receiver in line of sight with the microphones and separate the antennas in a “V” shape for better reception.
• Avoid placing the receiver near Wi-Fi routers or powerful RF equipment.
• Before the event, perform a distance test and adjust levels to avoid saturation.
