Yes - and in some instances it's TOO much. I've had a few people
experience difficulty setting the audio low enough for some MIC inputs.
The solution was to pull out the 386's and jumper the input to output
with a small wire in the IC socket.
But - for radios that require LOTS of audio like the System Fusion
Repeater and other older hardware (Kenwood TKR-750, MICOR, MASTR II), it
does work well as is. At least the unit is comprised of mostly
thru-hole components making it easier to work on and modify if necessary.
