Specification (Draft):

This amplifier has three audio inputs and two microphone inputs.

Three audio inputs are at constant level all the time. So you have to control volume level by the buttons on the remote panel. After adjustment of the each audio source (DVD Player 1 to 3), this amplifier must remember each volume level in memory. So next time we select a DVD player, then the volume level setting from memory is recalled. Same thing must be true for DVD Player 1 & 2.

When you slide a button on microphone 1 then music from DVD player will stop and microphone audio will go through amplifier. Same thing must be true for Microphone 2. However Microphone 1 has top priority over all the inputs. Microphone 2 has priority over 3 x DVD Player.  Microphone volume level must also be remember in the memory

DVD Player selection is done by input selector button on remote panel.

On-off control will provide standby function to amplifier.
