Wireless Microphone Systems
We do our best to keep healthy stocks across the many Wireless Microphone System SKUs but in the rare case where we don't have your required system in stock, please contact our sales team as we can often make your product to order by borrowing the system components (transmitters, receivers or mics) from other stocked systems.

The amplifier handles a 4Ω load or 70V/100V speaker runs, perfect for multiple speaker setups in small retail stores or doctor’s offices. A cool-running, powerful Class D amplifier delivers 100 watts with <0.1% THD and an outstanding Signal-to-Noise Ratio of >95dB, ensuring extremely clean performance under all conditions.
