Special care has gone into the design of the power supply of the TRANSIENT DESIGNER. The power supply is the heart of any electronic system, and the better it is, the better the whole system works. In an audio system, this translates into better sound quality, lower noise and lower distortion.

The power supply is based around a 15 VA torroidal transformer and is designed without an air gap to minimise induced hum and noise. The primary voltage may be selected between 230 V/50 Hz and 115 V/60 Hz by means of a recessed slide switch on the rear panel and a ground-lift switch is fitted for use where ground loops are causing hum problems. When the GND LIFT switch is set to off, the circuit ground is isolated from the chassis ground.

The detachable power cord is a standard 3-wire type fitted with an IEC mains connector; the transformer, power cord and mains connector have VDE, UL and CSA approvals. The fuses have values of 200 mA/230 V and 400 mA/115 V.

On the secondary side of the power supply, an RC combination is used to filter out noise and hum. Both half-waves are smoothed with 2 x 1000 µF capacitors in the positive and 2 x 1000 µF capaci- tors in the negative voltage supply path, and both lines use preci- sion voltage regulators for optimum stability. Deviations of only a few millivolts can impair audio quality, introducing artefacts such as loss of stereo imaging or a diffuse sound character. Particular care has gone into the circuit layout and component choice to minimise crosstalk between the audio circuitry and control voltages.
