This is my new plug-and-play design of the old Bally pinball Sounds Plus/Vocalizer (S+V) sound board pair used in Xenon and Early Flash Gordon pinball machines. My design uses current technology to replicate the function of the old sound board pair with a single board. My reproduction board is a direct replacement for the Sounds Plus Vocalizer (AS-2518-56/AS-2518-57) board pair. It will fit into the machine without modification. The circuit design is identical to my replacement Squawk & Talk sound board (for later machines). Only the shape is different.

About the first 300 Flash Gordons produced by Bally used the Sounds Plus/Vocalizer sound board pair. This is serial numbers 1000 to 1300. 1001 to 1010 are prototypes.

My design has the following stock features:
1. It utilizes the same machine mounting. Although it only uses the Sounds Plus (right) side, it uses the same connector locations.
2. It is a direct replacement, utilizing the same power provided to the stock board.
3. It contains volume mixing knobs to adjust the sounds and voices separately.

My design has extra features:
1. Extra volume knob (over the S+V) to adjust the background sound independently of the sounds and voices.
2. There is a switch to allow the merge of sounds so they don't turn off when others start.
3. The board only uses the +12v full bridge rectified power lines. It does not use the 5V power line.
4. All the sounds, voices, and backgrounds are customizable as they are WAV files on a MicroSD card.*
5. There are 8 sets of customizable sounds available.
6. There is a customizable Attract Mode sound.
7. Three relays can control external lighting mods (Ball in Play, Bonus Mode 1, Bonus Mode 2)

Included Sounds: You have the option to select one of eight different sound sets, which are contained on the MicroSD card (WAV files). I will supply you with many sound sets on the MicroSD card and custom ones, explained below.

Flash Gordon Stock and Custom Sounds:
Sound bank 0 is the default stock sounds for the machine.
Sound bank 1 has the same sounds as bank 0 but the background will auto escalate similar to the stock machine which escalates with each new sound commanded.
Sound bank 2 has the same sounds and background as bank 0, but many of the voices are from the Sounds Plus / Vocalizer sound board used on early Flash Gordon machines.
Sound bank 3 is delivered with a custom sound set with sounds and quotes from the Flash Gordon movie. See the video below where I demonstrate this custom sound set on a Flash Gordon machine. Also, see CaptN-Retro Youtube video showing the Flash Gordon custom sounds with the S&T board version.

Sound bank 4 is delivered with the original Bally French version.
Sound bank 5 is delivered with another custom sound set Dave at the YouTube channel Dave's Think Tank at sound bank 5. He demonstrates the sound bank at the end of his following video.
Sound bank 6 is empty. You can use it for future custom sounds.
Sound bank 7 has the numbers files for diagnostic Game Title number 15. The numbers files can be overwritten.

Xenon Stock and Custom Sounds:
Sound bank 0 is the default stock sounds for the machine.
Sound bank 1 is delivered with a copy of the files from sound bank 0. This is a great starting point to make your own sounds.
Sound bank 2 is delivered with a different version of the stock sounds with different equalization. These sounds may sound better on your machine depending on the speaker you have.
Sound bank 3 is empty and can be used for more versions of custom sounds in the future.
Sound bank 4 is also empty.
Sound bank 5 is a custom sound set. Most of the sounds are the same as stock, but the pop bumpers will rotate through 30 custom sounds from the original sound artist. An example is shown in the video below for sound bank 6.
Sound bank 6 is a second custom sound set. It has both custom pop bumper sounds and a custom looping background sound at 1538_0002_background.wav. I have four other alternative backgrounds on the MicroSD card that you can copy into this filename. You can replace it with anything you want. See the video below where I demonstrate both custom sound sets on a Xenon machine.

Sound bank 7 has the numbers files for diagnostic Game Title number 15. The numbers files can be overwritten for another custom set if you want.
