What happens if you power the amp down with the input cables pulled?

It should be noted that the "Behringer Rules" crowd will give them a pass for this, while a power related transient from the Drive Rack PA is an opportunity to slam dBx. Whatever.....

Yup, and for a simple reason. While there's a slight thump from the Behringers I use, it's no worse than some of the other, more expensive, amps I also have experience of and has certainly never been enough to worry any speaker drivers. The DRPA, on the other hand, is almost guaranteed to blow drivers when it loses power. This is a pretty big difference in my mind. Bob

I can`t offhand remember whether the Belringers have mute relays, but if they don`t, he might be hearing the distortion as the power supply voltages collapse. Ron(UK) |
