The Module runs the ELO Touch Screen and American DJ Controller.
It has a second Video Card that is USB SVGA and Second Audio Card is USB.

This also has USB Wireless 802.11 and CDRW that I burn Video & PIC's from my DSC-F717.
This has a Metal Plate that has 15 Pin VGA passthru along with Left/Right Audio from the Mixer.
Also another RCA out for Composite Video and Mini Stereo Jack for Booth from Mixer.
I have 2 of these cases, 1 has an American DJ Controller running ProMix and the other runs a BPM Studio RC-1 Controller for BPM Studio.

I am running a second Monitor Flat Panel Monitor from the Side VGA Plate for Karaoke.
Monitor is on a Heavy Duty Music Stand (Drilled Vesa Mounts), So no Big Clunky TV to Carry around.
Mounted in the Case as well is a Gemini KM-130 Karaoke 3 Mic Vocal Mixer.

I came in early to test this and the speaker performs at 200' away easily.
