similar devices on the market.
portant to connect the AC-GND capacitor (C5) to
the signal GND, as close as possible to the audio
inputs ground: this will guarantee high rejection of
any common mode spurious signals.
To simplify pc-board layout designs, each ampli-

The SVR capacitor (C6) has also to be connected
to the signal GND.

Even more important, this makes it possible to as close as possible to the Vs pins.
