I have been asked by a friend to look at options for delay circuits or devices.
This is for PA announcer intelligibility when using distributed horns.
Currently he uses a delay device based on a microcontroller, but its slightly limited in delay time, and slightly limited in frequency response. Not that frequency response is all that important, but a bandwidth of 400-8khz would be a good goal.
I'm just wondering what DSP options can fulfill this task?
Can miniDSP or similar process a simple delay of upwards of 1/4 s to 1.5 seconds?

I'd probably get a DCX and call it good. They're very cheap and all the hardware etc is done for you. Just plug and play.

Don't reinvent the wheel, there are existing commercial products for that exact purpose and more.
The above suggestion of a Behringer DCX is a good one. The DCX2496 has six programmable outputs, which ought to be enough for you. It has many capabilities beyond signal delay.
