Independent Headphone & Speaker Volume

[Russ-2]

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.

Thanks, Russ KD4JO

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.
