WARRANTY AND SEAGE
This solution demonstrator board is intended for potential customers to
evaluate the audio performance of the Mueta Class D amplifier solution in
an automotive configuration and for no any other use.
The MAD2x100 is not a finished product. Mueta does not accept any
warranty or liability claims against this board. All testing is conducted at
the user’s risk.
General Guidance
1. Ensure that all rotary controls are fully anti-clockwise (counter-
clockwise) and filter switch is in the off position.
2. When connecting any power or load to this equipment, please use
appropriate spade connectors.
Connection / power on procedure
1. Connect loudspeakers (or test load or measurement equipment)
across output + and – speaker terminal outputs
2. Connect muted audio source to each channel RCA phono input.
3. Power up audio source.
4. Apply power to MAD2x100 in the following sequence.
a. Ground
b. Permanent Live
c. Ignition Live
Input gain control
The input gain control does not reduce the input voltage to 0V – the input
is controlled from around 0.5V to 5V.
Power Supply Notes
The red LED indicates that there is power on the power terminals.
The green LED indicates that the power supply is supplying the amplifier.

Note 1 – The input impedance restriction is a limitation of power supply not the amplifier. The
amplifier contains short circuit protection circuitry
Note 2 – The power supply is designed for music output – not sine wave output. If you wish to
amplify sine waves, accurate measurements should be conducted at power output values of
<100W RMS driving a single channel only.
