The preamplifier works with the provided 24 VDC power supply.
Equipped with a single INPUT and OUTPUT, plus a GAIN control for adjusting the level of input signal, the
preamp is activated when jack cables are inserted into both the INPUT and OUTPUT sockets.
WARNING: Although all ground connections are correctly implemented on the STAT system (pickup, cables,
STAT PRE box and circuit), they are not directly connected to ground (and are therefore “floating”), as they
actually depend on the grounding connection of the device to which the STAT system is connected.
If that device is not properly grounded, or generates a ground loop, it is possible to experience hum. Solving
the problem requires attention to the device’s ground connection, usually via the GROUND LIFT switch.
In short: the ground connection must be provided by the device to which the STAT system is connected.
