Adam A77X pair (Used)

Tri-amplified monitor, 2 woofer 7″, A.R.T tweeter, 250W RMS

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 frequencies.
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!
