ADAM A77X Monitor Details
The brand new ADAM A77X Monitor might become a true game changer with all of its outstanding features. It is equipped with the same advanced technologies as the A7X, and is therefore very similar to the two-way speaker. The A77X, however, distinguishes itself with 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 monitoring.
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. Now, ADAM has brought the design to their AX Series!
Like all models of the AX series, the A77X features the ADAM proprietary X-ART tweeter. The "X" stands for "eXtended frequency response". Frequency response of the Accelerating Ribbon Technology has been drastically improved - now extending 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 in the A77X are identical with that of the A7X. With their large voice coils (1.5") and powerful amplifiers these woofers are capable of both very high maximum sound pressure levels, as well as very deep registers. The two woofers do not cover the same frequency bands: one of them is responsible for the (sub-) bass frequencies up to about 400Hz, and the other takes over most of the midrange.
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 of the A77X includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.
The rear panel of the monitor features several additional controls: a gain for the high frequencies (Â± 4dB), as well as two shelf filters for high and low frequencies. To ensure greater compatibility, ADAM has featured both XLR (balanced) and RCA (unbalanced) connectors.
