Audio level between Maestro and SmartSDR

If I use my Maestro to listen on a frequency, and then turn off the Maestro to listen using SmartSDR on the same frequency, I observe that the audio level is considerably lower on SmartSDR.  However if I change to another band with SmartSDR then the audio output levels are restored.  In my case I am listening to 50.085 MHz on the Maestro, but changing over to 50.085 on SmartSDR results in reduced noise level.  If I switch SmartSDR to 10m CW to audio comes right back up.  Then if I go back to 50.085 on SmartSDR the audio level is normal.  This is true for both the headphones, and powered speakers on my 6700.  73 Peter G3ZSS

This isn't a problem.  It is a consequence of the design.  SmartSDR for Windows is engineered to manage the audio gain of up to 8 slice receivers, as such the overall per slice gain is a little lower.  Maestro on the other hand only has to manage 2 slices and we also put a higher gain AF amplifier in the Maestro to overcome situations where it is used in higher ambient noise conditions (public locations).
