Article #2b: Myriad / IRN News mixing & buffering circuit (extended
copyright ©2001 Paul Blitz
This is a continuation of the Myriad stuff: this version has (a) 3 Myriad
inputs; (b) IRN input; (c) buffered outputs of (a) and (b) (eg to feed a
desk); Mixed Myriad with switched IRN (eg for station output)
Let me download the circuit details!

Adjusting the circuit
1) if you want 4 Myriad inputs rather than 3, then add another input &
output buffer & mixing resistor
2) if you want another switched audio (OB?) then duplicate the IRN bit
3) if you want more outputs: take a look at the article on the Buffer
Amplifuer & do a similar thing here!
Finally, if you need any help with the circuit in any way, then feel
free to email me with your questions.
