Title: Wire second audio source to amplifier?
Post by: patroyal on November 30, 2019, 07:31:02 AM

Hi,

I'm the lucky owner of a 044 Game King and would like to wire a second audio source to the amplifier so I can also use it to play background music. I bought a 2 channel audio mixer with 2x line in and 1x line out. The plan is to wire the Game King sounds and the music both to a line in, mix the signals and send the line out of the mixer to the amplifier board.

Could anybody help me with the correct wiring to achieve this? I can't make any sense out of it.

Specs of my amplifier board:
PN 13100400 Rev A
Vendor 1001780 Date 539
Ass No. 76928000

Pictures are attached. Greetings from Europe!

The multimedia lite 2 (MML2) boards used with S2000 and 3902 Game King MPUs have a jack for an auxiliary audio input.  The 044 MPU has the audio integrated into the MPU board itself and they didn't provide a jack for an external audio input on them.  I've attached a schematic diagram of the audio amplifier board.  Maybe that will help your cause?
