ADAM Audio S7A MK2 Active Main Monitor

ADAM Audio S7A MK2 Active Main Monitor Overview:

ADAM Audio monitors have earned a worldwide reputation as the preeminent tool for sound engineers based on technological innovations that weve established in the field of loudspeaker technology.

Amplification

An active-built complex, large top-class monitor has not yet been achieved because of the challenge presented by the heat generation of the high power amplifiers used in this type of device. In recent years, PWM (Pulse Width Modulation) amplifier technology had significantly improved in that only a fifth of the generated heat has to be dissipated a real breakthrough in terms of reliability and durability. This allows the S6X and the S7A MK2 to be flush mounted into the studio walls, since all the heat is emitted through the front of the cabinet and the heat sink temperatures remain moderate. Together with the built-in protection circuits the low, constant temperatures of these amplifiers result in reliable performance not possible with traditional AB amplifiers.

Control panel

In addition to the input sensitivity that can be adapted in the range of 10 dB, there are four other level controls that affect the individual amplifier modules. Shelving filters at both ends of the frequency spectrum and three fully parametric equalizers help compensate for standing waves in the control room. The EQs can be inserted separately or grouped so their effect can be directly evaluated.

In large film score mixing rooms, there may be a need to simulate theater sound. Based on the ISO 2969 standard, the DolbyX-Curve is used to achieve this. This filter engages a 3dB per-octave roll-off starting at 2kHz. Below the front input jack is a selector switch that activates this filter, eliminating the need for external processing during the film mix. In addition to the rear input there is an additional switchable XLR input on the front panel, allowing work with the monitor regardless of set-up.

FEATURES & BENEFITS:

X-ART tweeter, handmade in Berlin

• Allows longer operation with fewer signs of fatigue
• Their breakup is prevented by the folded diaphragms, distortions are effectively reduced to a minimum
• Advanced dynamic range due to acoustically effective diaphragm surface that is 2.5 times bigger (compared to a classic tweeter according to the piston principle)

The air velocity ratio of 4:1 during the sound generation by folded X-ART membrane

• Direct, fast response in the high-range even with complex transients

Ultra-light but extremely dimensionally stable woofer material

• Excellent transient response even at high sound levels without breakup of the diaphragm

4-way system with 2 x 15″ woofer and 2 x 9 midrange

• Very high resolution of the stereo image and extremely wide stereo base

Spacious bass reflex ports on the front

• Bass reproduction with very low compression

Highly efficient PWM amplifiers

• Low-distortion amplification at both low and high volume levels

Linear frequency response of 20 Hz to 50 kHz

• Unbiased reproduction in a wide frequency band

Maximum peak sound pressure per pair in 1 m 138 dB

• Powerful, compression-free sound reproduction even at very high sound levels

Sophisticated room acoustic adjustments

• Allows optimal adaptation to acoustically difficult listening environments or individual preferences

Analog XLR input
