VERY IMPORTANT:
Please read the following instructions carefully before installing your
Blacknote® Digital Stereo Amplifier
DSA150 SPECIAL
Italian Hi-Tech Digital Stereo Amplifier
Congratulations
Thank you for having purchased a Blacknote® product.
Introduction
The Blacknote DSA is a complete
line of Class D innovative digital
Amplifiers
The DSA150 SPECIAL is a true 150watt
superior Class D digital integrated
amplifier amplifier designed to satisfy
the
most
discriminating
audio
enthusiasts.
The DSA150 SPECIAL is able to deliver
uncompromised sound quality with the
typical great power and versatility of
such innovative technology.
The DSA150 SPECIAL has a full digital
Class D output stage powered by a
traditional massive Dual-Mono I.E. handcrafted transformers. Such large power easily ensures a
superb quality controls of the audio signal paths.
The DSA150 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 Double Mono Active Volume step-by-step
resistor control system while the six different Line Inputs, three RCA and three XLR are powered
thru electrical 24 Karat gold singularly incapsulated relays, guarantee a full isolated line silence
with zero negative feedback & crosstalk.
A proprietary Blacknote 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 DSA150 SPECIAL
amplifier joined with super wide bandwidth insure top class performance with level of accuracy
very hard to reach with traditional amplifiers.
The DSA150 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.

Once the DSA150 SPECIAL has been correctly assembled and positioned on a solid shelf and fully wired the player is ready
to play.
The DSA150 SPECIAL front Panel replies six basic function of the unit:
ON OFF - It turns the unit ON/OFF completely.

(DSA DOUBLE MONO ACTIVE VOLUME CONTROL)
The Double Mono Active Volume Control system of this unit is made with a Blacknote proprietary designed developed with
a Texas Instruments PGA2310/2320 devices feature 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; the volume control range is from
[-90dB to +10dB] stepping 0.5dB finely managed by high precision 0.1% resistors.
Due to the Double Mono set-up the Blacknote active Volume Control features also a sonically ideal balance control solution.
The Volume is conveniently lighted up on the DSA display to check it up on real time.
The quality of the Blacknote Double Mono Active Volume Control technology enable unsurpassed sonic performance for
traditional passive audio potentiometer.
(DSA DOUBLE MONO ACTIVE BALANCE CONTROL)
The Blacknote Double Mono Active Volume Control allows also a high quality Balance control based on the same
technology, it does not affect the performance of the amplifier even when a different level of db is required on the Left &
Right channel.
The Balance can be controlled pushing and hold the volume knob then rotating the knob on the channel wanted.
The Balance can be controlled through the remote control also.
The Balance is kept in the memory of the amplifier after 5 seconds of the assignment.
If the unit is set in Stand-By Mode thru the remote control specific button. The amplifier keeps
partially ON, ready to work at its max audio performance when turned ON completely.
(SOFTWARE)
The Software of the DSA can be update at the local Blacknote® distributor only.

(F.A.Q.)
QUESTION
Why the DSA can
impedance
&
loudspeakers?
DESCRIPTION
drive low
efficiency
•
The DSA is designed around
an innovative digital technology
enable the Blacknote® amplifier to
drive speaker down to 1ohm
impedance
without
clipping
troubles.
REASON/SOLUTION
The Technology of the DSA amplifier line is based
around an innovative Flat Load Independent
Frequency Response design allows perfect speaker
matching and stable frequency response with all
audio loudspeakers
Why the Double Mono Active
Volume control is better than
standard potentiometer solutions?
•
•
The insistence to have best possible
performance let Blacknote lab design a resistance
step-by-step potentiometer electronically regulated
to achieve the best performance and the max
convenience using it.
Why the AMP IN disables the
remote control and it can be
activated only from the front
panel?
•
Once the Power amplifier
mode is activated the remote is
totally disabled
For security reason there is only a front panel
switch can activate the Power Amplifier mode of
the DSA amplifier
