Product Overview
The compact, high-performance SoundTube MCA2004t amplifier is designed for continuous use in commercial and professional environments. It delivers 200W at 8 ohms or 70/100V constant voltage output across each of its four channels, providing the power and versatility needed for various audio applications. This Class D amplifier features Euroblock-style connectors for balanced and unbalanced audio signals, along with an input routing matrix mixer that allows all connected speakers to be powered by one or multiple sources.
To prevent distortion from overdriven bass frequencies, the amplifier includes a selectable 70 Hz high-pass filter. Additionally, subwoofer mode can be activated on Channels 1 and 2, applying a 120 Hz low-pass filter while enabling a 120 Hz high-pass option for the remaining channels. When subwoofer mode is selected for any channel, the output impedance automatically adjusts to 4 ohms.
