World's first 6-way audio grade linear power supply
The Keces Pier Series, to which the Keces P28 belongs, is already a very broadly positioned product line offered by the Keces Audio brand. The P28 is the undisputed top model of the product line and has no less than six zones.
Quantum Resonance Technology is a feature that Keces has used in other Keces Audio solutions, and which is now also found in the P28 Ultra Low Noise Linear Power Supply, namely Quantum Resonance Technology. This is to ensure that a subtle field is generated that makes all electromechanical components vibrate in unison in order to improve coherence and timing.
Of course, it should also be emphasised that the P28 features, among other things, four elegant Amp meters on the front to monitor 4 of the 6 currents, which will probably please many a hi-fi enthusiast.
Zone 1 can provide either 5 V, 7 V, 9 V or 12 V, Zone 2 and 3 each supply either 12 V, 15 V, 19 V or 24 V. Zone 4 offers a choice of 12 V or 15 V. There are two additional extra zones: number 5 will either supply 5 V or 9 V while the USB zone 6 will supply 5 V / 2.5 A with data throughput from USB B to USB A. Switching on is either done the traditional way by using the mains switch, but it can also be switched on by an externally supplied 12V switching voltage.
