Sounds Plus / Vocalizer Replacement Sound Board


Last Updated: 05Sep21

This is my new design of the old Bally pinball Sounds Plus/Vocalizer sound board used in Xenon and early Flash Gordon pinball machines. My design uses current technology to replicate the function of the old sound 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. Only the shape is different.

The board has the following stock features:
1. It utilizes the same machine mounting. Although only using the Sounds Plus 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 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 the sounds so they don't turn of when others start.
3. The board only uses the +12v full bridge 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 an 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)

* Durations for each of the sounds is stored in the program. You must also reprogram the ATMETA CPU on the board with the durations in order to change the lengths (mainly longer) of any of the voices. The sounds and backgrounds durations are not as important.

See and write a review on Google Business. This is a new review page so you might be the first to review my products.

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 three sound sets on the MicroSD card. Sound bank 0 contains a stock set of sounds which I recommend leaving unmodified so that you can always go back to stock sounds. Sound bank 1 contains an identical set of sounds as sound bank 0. This one is intended for you to try your hand at modifying sounds. You can try a couple and not have to re-create the entire set. Sound bank 2 is another set of stock sounds but with different equalization which may sound better on your machine. Sound bank 4 has a custom sound set for Flash Gordon machines. Sound bank 6 has a custom looping background sound for Xenon. Sound bank 7 has Number call outs for game number 15. You can use these for your game as well. I will include sound files in sub-directories for the other games as well.

Below is a photo of the version 0 board available for purchase. You can see the three relays off to the left for the optional 12 volt lighting mods. There is an adjustable 5v power supply with display. This should be kept at about 5 volts. There are the 3 volume knobs at the top of the board in blue for the background, sounds, and voices. The WAV file player is the big red board that contains a MicroSD card with all the sound files. The mono amplifier is off the to the right with another (over-all) volume knob.

Development Videos: I am documenting my design journey in my YouTube channel. These are some of the videos where I show my progress on Flash Gordon and Xenon machines. My reproduction Squawk & Talk board is shown in some videos. This design is identical to the reproduction Sounds Plus/Vocalizer board. Only the shape of the board is different:



Custom Sounds Help: I have also created a set of videos to help you create your own custom sound files for my replacement Squawk & Talk board. The first video shows you how to use Audacity to convert a sound file found on the internet to the appropriate sound file format. It also shows how to record your own voice for a sound file. The other videos are aids for recording your voice for all the phrases contained on the machine. You are to play the video while recording your voice. The video will tell you what to say and give you a chance to say each phrase. You record your whole session in one big sound file - then break it into the individual files needed for the board.



Custom Sounds for Download: This is a custom sound set for the Flash Gordon sent to me by a customer of my Replacement S&T board. You can see and hear this version in video #13 in my main set of S&T videos. You will get this sound set installed as bank 3 when you order one of my boards configured for Flash Gordon.
