I have for sale BRAND NEW NEVER USED NCS-3230 MULTI-Rx. For $250 shipped.

unprecedented functionality. Monitor any or all of up to 6 radios
simultaneously using only 2 speakers - NOT 6 ! In the Normal mode

the center and amplified 3 dB making it the dominant audio in the sound
field. And you can use speakers, headphones, or both simultaneously
(selectable). And there's more ... Pictures are available at web site
