Mini Digital Amplifier, with MIC Mixer and EQ

5. Audio Connection

5.1 Default output: 2x20Watt@4Ohm

The default output of amplifier is 2x20Watt@4Ohm. So, the user can connect the

amplifier output in the regular way. As the picture below:

5.2 Bridge connection: 1x40Watt@8Ohm

The MMA220 has the bridge connection, to double the output power at

1x40Watt@8Ohm. It will sum up the input left channel and input right channel to be

mono output, and the power is up to 40Watt.

The bridge connection is:

1x40Watt@8Ohm

2x20Watt@4Ohm

Switching to the

“STEREO”

Switching to the

“BRIDGE”

Connecting the two pins, like this

Connecting the four pins, like this
