Tidal Presencio LS









































Concept: fully balanced minimal path topology dual mono pre amplifier with fully regulated external power supply

True balanced concept without any sound-changing inverted signal generation

2 seperated cabinets for power supply (POWERDECK), line stage and phono control deck (LINEDECK)

Completely regulated power supply with galvanic seperation and variofiltering for "left", "right" and "control" for each channel of the LINEDECK, regulation boards outhoused from the powersupply directly at the amplifier boards

Completely separated power supplies for level control and isolated DOT-matrix display with level indicator ("min", "1 - 31", "max", "mute", "on", "1:1") with time delayed turn-off with "on"-indicator behind a mirror inside of the chrome plate

2 separated power cord inputs with different filtering for "Analog" and "Control"

3 x balanced input, 3 x unbalanced input incl. 1 x tape-loop, 3 x balanced phono input, 2 x balanced output, parallel volume controlled

Unique level adjustment: only 1 high precision resistor in signal path for level adjustment, controlled by an electronically and mechanically isolated motor driven ALPS potentiometer-A/D-converter-unit and 256 reed-relay, remote control for volume and intelligent soft mute

One input can be configurated as 1:1 direct mode for an external surround processor or as classical high level input

2-stack device with resonance controlled cylinders inside of the cabinets made out of Delrin and isolator feet to place it 'plug & play' on top of each other

6x remote output for up to 3 pair Impact Monobloc, intelligent soft start


Linedeck:

6 isolated amplifier modules

Separated discrete balanced output modules without sound-limited transformers

8 volume control boards with 256 relay and direct resistor access in the signal way without cascades, digitally controlled with fully analog switching and logarithmic resolution

Completely galvanic separated ground between "left, "right" and "control"
