SPL Track One Channel Strip - Manual (Page 19)

19 Track One
Built around a toroidal transformer, the power supply ensures a minimal electromagnetic field
with no hum or mechanical noise. The power supply‘s output side is filtered by an RC circuit
to extract noise and hums caused by your power service. 6000 µf capacitors smooth out the
positive and negative half waves.
The phantom power is derived from a separate winding in the transformer, a precise current
regulator a clean phantom power of 48 volts. Our high quality 0.1%/6,81 kOhm resistors
ensure the pristine quality of the phantom power supply.
