AVP G23 amp/speaker unit power question

[sccarlso]

Different query that previous post.  Hopefully simple!

My amp/speaker box on my G23 was hosed.  Buzzing sounds & RF noise from the fans especially.
My slot guy got me a replacement for free as he sold me the G23.

Got the replacement but good old IGT changed the power plug!  Old amp/speaker enclosure was a slightly different model, but an exact swap otherwise.

Both units have audio in plugs for R/L and Bass separately.
But old had a 4 pin molex for power, new has a 6 pin molex….  Ugh!

Old is listed 12v/24v with all 4 pins connected on the 4 pin molex to the amp.  Clearly has 12v on the right two pins & 24v on the left two by wire color.

New has only 24v listed, but has a 6 pin molex?

Tracing the audio power wire, the backplane indeed has a 6 pin molex.  Right two pins 12v, two center pins are not connected, left two pins are 24v.

The cable though, simply is 6 pin on the backplane on one side.  But is a 4 pin on the other.  Still has 4 power lines, just doesn’t have the two center pins which aren’t even connected on the backplane anyway.

Just a connector issue, so thinking I can simply replace the 4 pin molex with a 6 pin one, matching the wire colors that are on the 6 pin going to the backplane and it should get proper power seems logical to me and easy to do instead of waiting a week or more for a 6pin to 6pin audio power cable.

Theres no doc anywhere with the pinouts for the new amp with the 6 pin molex on it.  Just need to get it power.  lol

Anyone know the pinouts for power on this 6 pin plug in the amp, or have a G23 with a 6 pin power plug in their amp/speaker assy who can confirm if I simply match the pins exactly as the 6 pin backplane plug wiring color to get power to this amp correctly?  I’ll certainly multimeter the pin voltages at the backplane.  But no idea how I could verify the power lines going to the 6 pin on the amp are exactly the same as the 6 pin on the backplane.

But electrically speaking.  With any power only cable.  Power lines don’t switch pin locations, same color to same color on each side of the cable with the same plug used on each side to the same pins.

Is my logic valid here?  Worst I could do is connect 12v where 24v is needed I guess.  If anyone has a 6 pin to their amp/speaker assy.  It would be reassuring to know if it is indeed a matched line cable on each end from the 6 pin backplane audio power to the 6 pin amp power plug on the speaker assy.

Thanks in advance for any confirmation or info!

Both of my G23's have 6 pin power connectors for the speaker assy.  Here's wiring diagrams for the 4 and 6 pin cable and a picture of the 6 pin that maybe helpful in making your own cable if you end up having to go that route.  I didn't see a part number tag on the cable, but if you reach out to your seller they may have a 6 pin cable to go from J35 to the bottom of the speaker?

Exactly what I was looking for!

I was hoping it only needed 24v & a pin/connector change.  But there’s more wires.

On mine the two middle pins are not connected.  So I guess I’ll wait for my guy to get a cable…

But if I have  to, at least I could make this cable with the diagrams.

Huge thanks!!!

Yes, it has all 6 wires on the connector, but if you look at the speaker it's only using the 24VDC and GND.  The 12V and GND goes nowhere internally at the speaker end.  So all you need to do is get the +24V and GND where it needs to be and don't have to hook up the +12V.

[sccarlso]

Well heck, I have new 6 pin connectors for the amp & have made SMT solder joints…so that shouldn’t be hard at all.  At least the wire colors are correct for 24 & 12v lines!

If I clip the old 4 pin connector, I can just plug the 24v & GND to the correct pins on a new 6 pin connector to the amp!

Then the only other hassle I will have is the dang ticket printer power!  The backplane has the correct 4 pin molex connector for the BV & Ticket printer (BV is connected already & good), but the harness on this machine just has too many connector changes from its factory build vs more common plugs it seems, so things can’t just plug right up.  Ugh.

The printer power cable to the board switches from a 4 pin to an 8 (or 10) pin on the printer side I believe.  And it has a Netplex connector on board as well, but it’s not a std molex.  All I need from the board is 24v power for the printer, and use USB for the printer data.

I have an Epic 950L USB/Netplex for it, with a 4 pin molex for power.  BV is USB as well.  Does the printer also only need one 24v+ & ground line on its 4 pin molex as well?

Is there enough 24v amps on the audio power line where I could simply tap it in this connector change process for supplying 24v ticket printer power as well?

Diagram was excellent!  But I didn’t see the two 4 pin BV & Ticket power molex connectors listed on it that are on the bottom right corner of the board.   If there’s enough power on the amp line for both, that’s an easy cable to build to power both from it.

If not, I’m thinking I can take the removed 4 pin plug from the amp cable and use it to replace the 8 (or 10) pin connector that’s on the cable now for printer power, and finally have the right plugs for everything!

Not sure, but I “think” Epic has a doc that shows the power plug pinout on the printer itself.  Are 4 pin ticket printer power connectors standardized?  If so do you know the pinouts? 

I can easily meter the cable from the ticket printer power on the backplane to verify 24v & ground.  But eh, can’t do that on the unpowered printer itself so I connect the right pins & don’t fry it!  lol

Do ya have a backplane diagram showing two 4 pin connectors for the BV & printer power?  Or know the 4 pin molex ticket printer power plug pinouts?

If I can verify the proper pins for 24v+ and ground on the ticket printer 4 pin molex.  And just put a 4 pin connector on with the pins in the right place & my printer should be finally up and working too and done!

Thanks in advance if you have any related diagrams or recommendations to get power to the printer in a proper way.

My G23 has a 8 pin connector just to the right of backplane for printer:

[sccarlso]

Yep!  That’s what I’ve got.

Printer needs a 4 pin though.  But found a pinout for the Epic printer 4 pin plug. 👍

Only needs pin 1 for power, pin 2 for ground.

Probably best to not tie into audio power, so I think I’ll go with pulling 24v and ground from the actual printer power plug to a 4 pin to match the printer power plug.  👍

Thanks!

Amp wiring is good!  😁

Ticket printer has power as well.  But alas it has Ithica template firmware.  🤨

New topic though.

Many thanks!
