...for an intercom. I've had to build three custom intercom stations into a 3-man film dubbing console, and the mics (Beyer cardioids, sleeve-mounted and acting rather more omni... though with slightly low output) sound flat-ish, but could certainly use a little prescence peak.
-If I talk into the Trilogy panel station that's nearby, and feeding the same Trilogy Orator comm. system, the signal 'cuts through' the mid-band noise in the machine room quite nicely. I suspect that they have a peakier mic, and then possibly a slight prescence lift. Here's a couple of their panels:
-Does anyone have a cheap-n-cheerful prescence-boost (but otherwise unity-gain) schematic?
I'm using SSM2017s as the front end preamps, and I'm driving SSM2142 line drivers, I could probably squeeze a single or dual op-amp circuit in there, providing that it doesn't get too physically intrusive.
Cheers,
Keef
