[Motorola] Audio mixer (wasRe: Low band radios)

Sun, 17 Mar 2002 19:35:26 -0500

Hello, All!

For a quick, convenient mixer, you might try either a Behringer Eurorack
MX902 (with an inverter for the power), or a Peavey RQ200 (which can use
batteries...2 x 9v...or a 16VAC supply). The Behringer is the better of the
two, and can be had for under $90.

73!
