Audes ST-900 power conditioner

The Audes ST-900 power conditioner is designed to power high-end and hi-fi AV equipment.
It has five outputs with a total power of 900W.

The main element of the device is a toroidal transformer 230 VAC/115 + 115 VAC developed by Audes, which isolates the devices from the home network.
Despite the considerable power of such transformers, the design of the power conditioner completely excludes harmful electromagnetic radiation.

The ST-900 transformer was designed to operate as a low-pass filter with a cut-off at 800 Hz since all electrical mains disturbances occur at much higher frequencies.
Second, the filtering effect is caused by the self-induction of a very large core, so the magnetic flux cannot change instantaneously in the event of a transient disturbance.
Finally, the transformer prevents any DC shift in the grid from reaching the equipment connected to the power conditioner.

High-quality CEE 7/3 sockets are galvanically isolated from an external power supply. The transformer is equipped with a reliable electrostatic shield.
Incoming electrical interference is counteracted according to the principle of mutual cancellation. The secondary winding of the transformer is split in half and has an artificial center tap connected to the ground terminals of each outlet. All of the above technical aspects make it possible to almost completely eliminate the noise of the mains and provide reliable, high-quality power supply for audio equipment.
Using the ST-900 with all AV equipment, both solid state and tube, improves the quality of sound reproduction. The best results are obtained when the power conditioner is used with power amplifiers.
