I’m using a mixing board for my setup as well. I used a SoundCraft EPM-8 (EPM-6) will also work. The 8 says 8 channels, but it’s really 12. 8 mono and 2 stereo. Right now I only have KX3, a nice used K3 is in the very near future and is why I set this up.
Channel 1: Microphone Channel 2: Output from USB sound card Channel 7: Receive main from KX3 Channel 8: Receive sub from KX3 Aux 1: Mic input to KX3 Monitor Left: Left speaker Monitor Right: Right speaker Master Mix Left: RX Main for USB sound card Master Mix Right: RX Sub for USB sound card The K3s will plug in as follows: Channel 5: Receive main from K3s Channel 6: Receive sub from K3s Aux2: Mic input to KX3. I can mute individual channels, adjust volume and EQ for each. I can dial down the monitors so I’m not hearing the speakers if I want to be silent during digital modes. Also using the faders on channel 1 and 2, I can mix it into the monitors during transmit so I can hear myself. I will have make a box to switch the PTT, keyer to the proper radio. Not a big deal. The other cool thing is I can adjust what I hear in each ear of the headphones when running Dual watch on the KX3. Plus I can swap the ears with a turn of the knob so the watch matches what I see on the PX3 (e.g. which ever frequency is lower goes to the left ear, the higher frequency goes to the right). That way ears match the visual. Most of this setup came from W3YY (http://w3yy.com/audio_control_system.htm). He has it setup with isolators and level shifters since pro equipment runs at higher levels than consumer. I also used the isolators and line level shifters. Works well. I’m planing on setting the headphone output of the computer into one of the stereo channels. That way I can use the same speakers for music when I’m not on the radio. 73, Joe - KO8V > On Feb 17, 2016, at 5:28 PM, Joel Black <joel.b.bl...@gmail.com> wrote: > > Yep, I’ve looked and there is a *lot* of information on this reflector about > the subject. > > I have worked with David Anderson, GM4JJJ, on setting up my KX3 trying to > minimize the connecting and disconnecting of cables to my Focusrite 2i2 sound > card.
