AM7LAM-U is the top model of the Ambient Acoustics lab created specialy for audiophiles with Seven BA drivers per ear with unique LAM (live acoustic mod) technology!
(U- means "Universal fit")
It implements a full set of functions for manual control of the sound signature! In addition to manual control of the bass level (manual adjustment is available in the step-by-step control of low frequencies in four positions 0, +6, +10 and + 14dB) it provides the possibility of adjusting the level of the middle frequencies, so-called vocal zone, with two levels 0dB and + 5dB !
In addition, AM7LAM-U is the flagship model of Ambient Acoustics of the frequency range extension! The depth of the lower frequency range reaches infra-low frequencies perceived by human only as a vibration, while the high-frequency boundary goes far beyond the range audible by the human ear!
In-earphones AM7LAM-U is a versatile and very complexity miniature speaker system in the ear that can be tuned to any sound source, any musical styles and for any most demanding and sophisticated listener.
Frequency Response AM7LAM-U
(IEC711 coupler + Pinna Simulator)
|AM7LAM-U sound has stunning "lightness" which is achieved by compliance in the resulting frequency response of the resonant phenomena of ears and ear canals with human perception of sound in free field conditions, as well as through the use of metal in the construction of the sound bores crossover.|
|Uniqueness LAM technology consists in that when switching modes total earphone resistance substantially unchanged and therefore the amplifiers in players do not change the mode from a low impedance amplification to high-impedance load!|
Electrical Impedance Curve of AM7LAM-U
Electrical Phase Curve AM7LAM-U
|Using of Impedance and Phase correction - a unique development of Ambient Acoustics lab, is reduces the impact of the internal circuitry of the amplifiers on the final sound signature of the earphones by raising the linearity of the electrical impedance and electrical phase curves of earhones, which, in turn, significantly increases the "naturalness" and "fusion" of sound!|
Unique "LAM"(Live Acoustic Mod) technology was created by the Ambient Acoustics lab. specifically for audiophiles and sound lovers applied in AM7LAM-U and manual adjustment for user is available in a stepwise control of low frequencies in four positions: 0, +6, +10 and + 14dB and adjustment of the level of the vocal zone: 0 and + 5dB
