The OS Acoustics DB7 is a high-precision reference studio monitor. Offering exceptional frequency response and time domain coherency. Ultra-rigid, high-fidelity drive units operate in pistonic motion throughout the working frequency range, lowering distortion and maintaining harmonic purity.
Powered by the best class-D amplifiers on the market, offering unequaled sonic performance and huge power reserves, the DB7 delivers a breathtaking performance that is clean, dynamic, open and articulate.
The DB7 is a true reference monitor, featuring a highly linear frequency response and advanced phase correction algorithm for natural time coherency, delivering absolute clarity and lifelike stereo imaging. The DB7 is perfect for any audio work where a high level of accuracy is required, including Mixing, Mastering, Broadcast, Film, TV and any other application where an absolute reference is required.
Ceramic coated magnesium is a near perfect tweeter diaphragm material, damping unwanted resonances with an especially low moving mass of only 0.2 Grams. Powered by a 150W RMS amplifier gives an incredibly fast, highly accurate and well-controlled impulse. Transient response is further improved by accurately time aligning the total system phase response, compensating for the drivers’ minimum phase characteristic, improving natural timbre, restoring time coherency and lowering listening fatigue.
The cabinet has been subjected to a meticulous study in Comsol multiphysics leading Finite Element Analysis software. A complex latticework of bracing has significantly reduced cabinet resonances, with front baffle vibrations being more than halved. The low-frequency driver is held rigid by significant bracing supports across four of its axes, stopping any twisting or rocking motion, revealing more subtle nuances and even more micro-dynamics. The cabinets are highly repeatable, cut to very fine tolerances with computerized numerical control machining. Finished in a beautiful veneered black oak.
The onboard DSP module offers a selection of 8 presets. Choose from critically flat or voiced, each with the option to enable or disable the FIR phase correction filter. Finally, for smaller rooms, you can also choose to apply the same presets with a small-room boundary correction, which counteracts the effects of local boundary reinforcements in the low frequencies.
The class-D T-Pro2 amplifier module offers unequalled audiophile specifications, incredible power reserves and high damping factor ensuring fast, tight control of dynamics and bass transients. Configured to comply with ErP (1275/2008/EC) and Energy Star directives, using less than 0.5 watts in standby mode. Intelligent Standby Signal Processing in the DSP initiates standby mode when no signal has been detected for a period of 15 minutes. When activated the amplifier power consumption is typically reduced to 0.2 watts. The amplifier automatically exits standby mode as soon as a signal is redetected, typically waking up in 660 milliseconds without audible pops and clicks inherent in other designs.
