AUDIO ANALOGUE ABSOLUTE
Preamplifier
Code: 70371145
All our products are covered by Italian warranty.
Inductive power supply to minimize main noise and two transformers of about 50W with electrostatic shielding, magnetic shielding and resin coating.
Zero global feedback from input to output.
Fully differential circuit (differential input and differential output).
Each stage is on separate boards and in fully dual-mono configuration from the power supply.
The preamp boards are mechanically shielded from the power supply section.
Relay volume control that compared to semiconductor controls provides a significant improvement in distortion due to the quality of the resistors used compared to those that can be produced inside a semiconductor.
Relay input switches to minimize non-linearities and disconnect unused inputs.
Stage of gain with property structure SeGeSTA.
Oversized traditional mounting military resistors to minimize thermal distortion.
Audiograde capacitors.
Three stereo RCA inputs.
Two balanced stereo inputs.
Two stereo RCA outputs.
Two XLR stereo outputs.
Managed by a microcontroller.
Internal wiring and power cable Airtech.
