Power amplifier input in the Dynacord mixer
Also, when using this input, no volume or power supply will affect this input. One thing some people do is connect the Mon outputs to this input.
At the top of these inputs is a master audio output that you can use to connect your device to an effector and feed the effector's output back into the mixer.
This will allow you to apply the desired effect to the output sound of the device by connecting an effector to your device if the Dynacord device does not have the desired sound effect (FX).
The power amplifier input, except for the above, will allow you to continue using the amplifier in case of mixer failure or noise in the mixer.
