The DSA-150 SPECIAL is a Dual-Mono I.E. handcrafted transformers amplifier easily ensures a superb quality controls of the audio signal paths.
The DSA-150 SPECIAL has the internal preamplifier and power amplifier stages perfectly separated can be singularly managed to set up, as per user needs, double passive amplification audio systems for premium quality & sound performance.
The preamplifier stage is controlled with a superior proprietary designed Active Volume Control system features fine resistors step-by-step DOUBLE MONO high end performance for superior resolution, lowest distortion and perfect channel balance.
The active preamp stage allows a +10dB gain for best resolution and perfect unit control stepping 0.5dB finely managed by high precision 0.1% resistors.
The quality of the Blacknote Double Mono Active Volume Control technology enable unsurpassed sonic performance for traditional passive audio potentiometer.
Besides the six different Line Inputs, three RCA and three XLR are powered thru electrical 24 Karat gold singularly encapsulated relays, guarantee a full isolated line silence with zero negative feedback & crosstalk.
A proprietary design enables real “Flat Load Independent-Frequency Response” design which allows perfect matching with any (hi-end) audio speaker of the market. The FLI-FR system apart of keeping the frequency response stable independently of the speaker load enable a perfect linear response down to remarkable 1ohm matching.
Real 150 watt per channel are able to effectively drive almost all the home speakers of the market, besides the very low output noise & impedance of the Blacknote DSA-150 SPECIAL amplifier joined with super wide bandwidth insure top class performance with level of accuracy very hard to reach with traditional amplifiers.
The DSA-150 SPECIAL is fully remoted with a flat elegant handset allows a control deeply completes the unique features of one of the most innovative amplification system available today.
