Soundtube MCA2004t - Multi-Channel Class D Audio Amplifier

The SoundTube MCA2004t audio distribution amplifier is a high-performance audio amplifier that is designed for continuous use in commercial and professional applications. The high efficiency Class "D" amplifier design offers high performance in a compact design. Performance features of the MCA2004t amplifier are flexible audio input connections for both balanced and unbalanced audio signals. The amplifier input uses two removable Euroblock style connectors to interface with the input source. The amplifier's input routing feature allows the distribution of the input signal to the selected output. This feature allows all connected speakers to be driven by a single or multiple sources.

The amplifier offers 70Hz switchable high pass filters to avoid over driven bass distortion and speaker line transformer saturation from low frequencies. SUB or subwoofer mode allows Channel 1 and Channel 2 to be switchable subwoofer outputs. This mode applies a 120Hz low pass filter to either, or both Channel 1 and Channel 2 and allows for a 120Hz high pass filter to the remaining channels. When this mode is selected for a particular channel, the output impedance will be automatically changed to 4 ohms.

This amplifier has auto signal sense or a deep sleep trigger, as well as an auxiliary port used to remotely monitor the health of the amplifier. The MCA2004t's protection circuitry includes temperature, short circuit, DC offset, and current overload protection. This amplifier is designed to provide long term reliability of operation and includes several features to ensure many years of trouble-free operation.
