Sound Performance Lab 2048 Power Supply, Specifications

Power SupplySpecifications

Built around a toroidal transformer,the power supply allows for 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.6000µf capacitors smooth out the positive and negative

half waves.

The supply voltage can be set to 230 V/50 Hz or 115 V/60 Hz.Check your

country’s power requirements for the appropriate setting.An AC power cord

is included to feed the IEC-spec, 3-prong connector.Transformer, AC cord

and IEC-receptacle are VDE,UL and CSA approved. The main fuse is rated at

315mA.

Chassis ground and AC ground can be physically disconnected by the

“Ground Lift”switch (GND LIFT). This helps to eliminate hums.
