@Danr posted:So I ordered the transmit/receive modules and couple of amplifiers along with some other things I needed. We'll see what happens.
I thought about a tether awhile back but I didn't want the extra tether because I was thinking I could run them as just the A, an AB or AA. Reality is they have been and ABA since I got 10 years ago. Would the PS2 audio amp support 3 speakers?
Latency could be an issue for sounds other than the prime movers. I don't use most of the sounds but I can see, or hear, that 3 horns or 3 bells sounding in each unit would not be very prototypical, even more so if they were out of phase.
The description and instructions for the send/receive modules is pretty thin. We will find out when we get them just how flexible, or inflexible, they are. I always loved products that came with instructions that said: "Congratulations, you buy nice product".
Keep in mind that I am not an electronics guy - ask me about a watch instead, but I'll let you know what happens.
Yep, it's always fun to find information on these products. That's why I looked around and posted some basic information that should get you close to running.
I don't know if the PS/2 audio amp would be happy with three speakers, but probably if they were all 16 ohm and it's a 3V board. OTOH, sticking an extra little amp in shouldn't be that hard.
The latency can be an issue, not so much for the horns but probably the crew talk for sure. I just fired up six Legacy F3 units, all with sound using #99. The crew talk is comical as they all react at slightly different rates. The prime mover, OTOH, sounds outstanding, and it shakes the walls with six units running at full volume! The horn is great as well, it's a 12 chime horn it sounds like.
