BURMESTER 911 MK3

Like all Burmester power amps, the 911 MK3 is built fully balanced and DCcoupled
without any distorting capacitors in the signal-path.
The new MK3 version distinguishes itself from its predecessor mainly by its
completely re-designed output stages, widely in class-A and new silver internal
cabling. A further characteristic attribute are the 911’s silver anodised
frame components and heat sinks in their distinctive Burmester design.
All older MK1 and 2 versions can be upgraded to MK3. In this process they receive a new
factory warranty. An upgrade entails exchanging the circuit boards of the output stages
against the new hardware modules of the MK3. Furthermore, the interior wiring is completely
upgraded to Burmester SILVER for signal-processing connections. Our new pure silver
speaker wire (8 mm²) is used for connecting the output boards with the binding posts. The
upgrade does not change the housing colour, however.
A special feature of the 911 MK3 is its extremely high damping factor. This high damping
factor coupled with the ability to quickly deliver large amounts of current enable the amp
to effortlessly drive virtually any loudspeaker over its wide frequency response. The 911
MK3 is capable of delivering high currents continuously and thus easily controlling speakers
with lowest impedance values and most complex loads. The frequency response is
practically load-independent. Very good spatial resolution, natural musical warmth and negligible
distortion characterize the sound of the 911 MK3.
The 911 MK3 is widely acclaimed for its naturally warm musicality and detailed imaging. The
911 MK3 is unsurpassed in its ability to extract the smallest sonic detail from the world’s best
speakers.
Like all our stereo power amps, the 911 MK3 can be bridged to mono via external monoadapter.
Of course, a pair of Burmester power amps is capable of driving loudspeaker in
bi-amping mode with the help of the external bi-amping adapter. The adapters provide
flexibility to switch between the two operating modes. The 911 MK3 can also be ordered as
mono version.
Like all Burmester products, the 911 MK3 is carefully handcrafted in the Berlin manufacture.
Only selected parts with narrow tolerances are used. Our supplier for the aluminium heat
sinks, pressed with Burmester specified tools, is also based in Berlin. All Burmester products
are carefully tested before they leave the company facilities. Following the performance
test is a computer-aided set of measurements and a 7-day test run at full load. After
the burn-in period the computer tests are repeated. The test results have to equal the first
measurements as well as our stored reference data. The next stage is marked by the individual
listening test, including the trial of all operating functions. Only when all results meet
our standards the unit will be packed and shipped.
Thanks to this tremendous effort combined with the intelligent protective circuit we can guarantee
the high degree of reliability even under extreme conditions. Standardversion mit
Chromwinkel, Chromdreieck graviert, Gehäuse silberfarbig eloxiert. Sonderanfertigungen
