A revolutionary formula: 2 x 7 = 77
In some set-ups it can be advisable to use a horizontally designed
speaker rather than a vertical one. Until now, such monitors were only
available within the SX top line.
The brand new A77X, due to its outstanding features, might become a
true game changer: Equipped with the same advanced technologies as the A7X,
it therefore is very similar to the two-way speaker. The A77X, however,
distinguishes itself by much higher, compression-free maximum sound
pressure levels and dynamics. Due to its power and radiation
characteristics, it also is perfectly suited for both near- and midfield
Like all models of the AX series, the A77X features the ADAM proprietary X-ART
tweeter. The ‘X’ stands for ‘eXtended frequency response’ and thus for
one of the features of the Accelerating Ribbon Technology that has been
drastically improved: the frequency response.
It now extends all the
way up to 50kHz. In addition, the X-ART tweeter has higher efficiency
and higher maximum sound pressure levels.
The two 7” woofers are identical with that of the A7X. With their
large voice coils (1.5”) and powerful amplifiers, they are capable of
both very high maximum sound pressure levels as well as very deep
registers. The woofers do not cover the same frequency bands: while both
of them are responsible for the (sub-) bass frequencies up to about
400Hz, only one of them reproduces the midrange. This prevents
interferences between the two drivers.
Amplifiers / controls
Each driver has its own dedicated amplifier. A 50W A/B amp is
responsible for the X-ART tweeter, while the bass-/midwoofers are driven
by a 100W PWM amp each. The front panel includes a power switch and a
control for the volume that retains the volume setting independently
from the on/off switch.
The rear panel features several additional controls: a gain for the
high frequencies (± 4dB) and two shelf filters for high and low
To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.
WORLD PREMIERE at the Prolight+Sound 2011
The A77X will be showcased for the very first time at the Prolight+Sound 2011 (Frankfurt am Main/Germany). We are looking forward to seeing you at booth C51 in Hall 6.1!
