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 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 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 protection circuitry includes
temperature, short circuit, DC offset, and current overload protection.
This amplifieri s designed to provide long term reliability of operation and
includes several features to ensure many years of trouble-free operation.

1. Power Indicator LED – GREEN LED indicates amplifier POWER ON. While in auto sense sleep mode, RED LED indicates amplifier in "STANDBY".
LED OFF indicates amplifier POWER OFF, or while in deep sleep trigger mode, LED OFF also indicates amplifier in "STANDBY".
2. Channel Status LED – LED is normally OFF. GREEN LED indicates signal input. RED LED indicates amplifier limiting.
a. Amplifier Protection Error – In the event of thermal or over current protection, ORANGE LED will illuminate for the channel in protection.
The amplifier output will shut off for the respective channel until protection is no longer needed.
1. Speaker Output – This removable euroblock type of connector is used to connect the amplifier output section to a loudspeaker using a direct
or constant voltage connection. Speakers with an impedance of 4 – 8 ohms and constant voltage 25/70/100v may be connected to these
terminals. (Note: make sure dip switch selection is set for the proper load). Please be certain to check the polarity of your speaker connections.
A removable 4 pole euroblock style connector is provided for the speaker connection and will accept up to a 12-gauge wire. Strip the ends of
your wires about ¼” from the end. Loosen the screws in the connector and insert the stripped ends into the respective + and – sides of the
terminal block. Tighten the screws down to clamp the wire in place.
2. Audio Line Input – This is a removable euroblock type of connector that is used for balanced and unbalanced audio input signals. For
balanced input connection, connect the positive signal wire to the positive (+) input pin, connect the negative signal wire to the negative (-) input
pin, and connect the ground wire to the ground input pin. For an unbalanced input connection, connect the signal wire of the audio cable into
the positive (+) input pin and connect the ground wire of the audio cable to the negative (-) ground input pin.
3. Input Levels – gain adjustment control for setting the amplifier volume.
4. Dip Switch One (DS1) – Please refer to the operation section of the manual for further information.
5. Dip Switch Two (DS2) – Please refer to the operation section of the manual for further information.
6. Deep Sleep Trigger (Low Energy Mode) and Amp Status Auxiliary Port – This is a removable euroblock type of connector that is used to
remotely control the on/deep sleep function and monitor the Amp Status features. Please refer to the operation section of this manual for further
information.
7. Line Cord Power Socket – This is a standard IEC style 3 pin power connector socket to connect the approved provided power cord from
the amplifier to the wall outlet. Use only the correct power cord for the country in which the amplifier is to be used or damage to the amplifier
may occur.
