Power Supply

A stable,low ripple torroidal power supply is the foundation for any high-fidelity sound shaping.

The GND-LIFT switch helps eliminate hums caused by ground loops.

Phantom Power with a complex filtering scheme and highly selected components.

The following graph shows the correct wiring for connecting un- balanced signals to the balanced XLR connectors.

VERY IMPORTANT

Phantom power must be switched off before unbalanced signals are connected! Otherwise short circuits cause damages!

Built around a torroidal transformer, the power supply allows for a minimal electromagnetic field with no hum or mechanical noise.

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 fuses are rated at 315mA (230 V) and 500 mA (115 V).

Chassis ground and AC ground can be physically disconnected by the “Ground Lift” switch (GND LIFT). This helps to eliminate hums.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 phantom power is derived from a separate winding in the transformer. Filtered and rectified by a series of zener diodes and transistors, a clean 48 volts leaves the circuitry.This supply voltage reaches the phantom power switch through the PCB where another RC circuit stabilises the supply again. Our high quality 0.1%/6,81 kOhm resistors ensure the pristine quality of the phantom power supply.
