Russ, There is a input A and input B switch on the SP3. I only use input A to the speaker, so when on headphones I push the A/B switch on the SP3 to mute the speaker.
I have a Behringer MicroAmp HA400 4 channel stereo headphone amplifier I use for field day, when we might have multiple folks on headphones listening to the radio. That could be used as a separate volume control for your headphones. 73, Hoop K9QJS On Sep 12, 2016, at 1:38 PM, Russ <mundschen...@msn.com> wrote: Hi: I currently feed a powered speaker with the constant line output of my K3. I can individually adjust that speaker's volume locally and the HP volume on the K3. I'm contemplating the purchase of an SP-3. As this speaker is unpowered, I will have to use the K3 power amp and am afraid that I will lose the individual volume control versatility I have. If this is the case - would it be possible to repurpose the sub-rx (I don't have one) AF gain "ring" to control the speaker amp level. My understanding is that the speaker out and HP out's are fed by separate DAC's.
