DESCRIPTION:

The SOUNDTUBE MCA2004t audio distribution amplifier is a high-
performance audio amplifier that is designed for continuous use in commer-
cial and professional applications. The high efficiency Class " D" amplifier
design offers high performance in a compact design.
Performance features of the SOUNDTUBE MCA2004t amplifier a re f l exible
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 h igh p ass filters to a v o i d over dr iven
bass distortion and speaker line transformer saturation from low frequencies.
"SUB" or subwoofer mode is another feature offered by the MCA2004t. This
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 SOUNDTUBE MCA2004t's
temperature, short circuit, DC offset, and current overload protection.
This amplifier i s designed to provide long term reliability of operation and
includes several features to ensure many years of trouble-free operation.
Warning
Do not spec or install amplifier near support beam, ventilation duct or
other structure that may interfere with amplifier function or dispersion.
