Adam A7X er en stor oppgradering fra den monitoren mange kjenner så godt, Adam A7. I nye A7X har man fått en mer optimal balanse i det lavere bassregisteret, da den nye 7-tommeren har en langt større svingspole enn tidligere, samt at forsterkerelementet er blitt dobbelt så kraftig. Denne kombinasjonen gir et kraftigere lydtrykk med mindre forvregning enn normalt, og en meget dynamisk og musikalsk gjengivelse.
Dog ligger den største forskjellen kanskje i den nye X-ART bånddiskanten. Den er mer effektiv, har et kraftigere SPL og en frekvensrespons på opp til 50 kHz. Hvert element har sin egen dedikerte forsterker. En 50W A/B forsterker tar seg av "forsyningene" til X-ART diskanten, mens 7-tommeren blir drevet av en 100W PWM-forsterker. Frontpanelet på ADAM A7X inkluderer en strømbryter og en volum-kontroll. Alle kabinetter er også ny-designet, og hele serien er bestykket med 2 bassporter.
Hver driver har sin egen dedikerte forsterker. A 50W A / B forsterker er ansvarlig for X-ART diskant, mens midwoofer blir drevet av en 100W PWM forsterker. Frontpanelet på ADAM A7X inkluderer en strømbryter og en kontroll for volumet som beholder voluminnstilling uavhengig av / på bryter.
ADAMs A7 & A7X: the evolution of a legend
The predecessor to the A7X, the A7, became the most famous of all ADAM monitors in a very short time. Not only has it been reviewed over three dozen times with outstanding results, it has also received numerous awards. The A7 quickly gained mass appeal, praised in many of the world’s largest internet forums. Still today, the A7 are the reference monitors in many smaller studios.
With the A7X, ADAM Audio proudly presents the evolution of a legend. It takes everything that made the A7 such an outstanding speaker to a new level.
Driver technology
The first aspect that distiguishes the old from the new model is the 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 a higher efficiency and higher maximum sound pressure levels.
The perfect integration with the lower frequencies has been achieved with a newly designed 7” midwoofer. It has been redesigned with a much bigger voice coil (1.5”) and is driven by an amplifier with twice the power compared to its predecessor. This combination produces an amazing sound and pressure levels with an almost distortion-free musical reproduction.
Amplifiers / controls
Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the midwoofer is being driven by a 100W PWM amp. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.
On the rear panel are 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.
