The PS1 is a very tightly regulated, very low impedance power supply. It is specifically designed as a high noise rejection type, such that AC line noise and harmonic noise is not transferred to the DC regulated output powering the field coil. This unique feature damps any induced motor voice coil modulated signal from the field coil, shunting this AC induced audio signal at the power supply.

The result is "locked down" pure DC power to the driver, with no overlying AC audio signal.

The supply is adjustable from 9 to 12.5 volts, and can deliver constant DC current up to 2 amps. This allows the listener to significantly modify the "total Q" and overall character of a loudspeaker, and thereby tune it to their personal listening preference.

The rejection ratio of this regulated supply is over 70 dB. Input power is configurable to order, for 115 or 230 volt 50/60 Hz operation. Two 6-foot XLR cables are included as standard, however they can also be configured to your needs.

We are delighted that Whammerdyne Heavy Industries manufacturers these remarkable power supplies in a partnership with Songer Audio.
