My OPUS 90W seems to take around 30 seconds until it sends 12V to the remote delay pin. My machine starts in 20ish seconds, so that's nearly 10 seconds of music playing without anything. No way to change this I assume? Did they ever release source code to what's on that Atmel MCU?
Anyway, I might just put together a simple 555 timer to take care of this... oh well.
