Pro Tools company branch out with the RMS line of studio reference monitors 17/04/07
Digidesign have announced a new family of bi-amplified, professional-grade studio reference monitorsâ€”the Reference Monitor Series (RMS), developed jointly with PMC (the Professional Monitor Company, based in the UK). Digidesign say that the new RMS monitors unite the companyâ€™s deep expertise in digital audio with PMCâ€™s legacy for fine, cutting-edge loudspeaker designs and meticulous manufacturing.
Gannon Kashiwa, market manager for Digidesignâ€™s professional products told us, â€œFor many years Digidesignâ€™s commitment to developing state-of-the-art professional recording technologies has helped artists, engineers, and producers alike create award-winning recordings with unrivalled audio purity. The new RMS monitors are a natural complement to our existing product line and a logical extension of our commitment to achieving consistent and pure sound from input to output. PMC and Digidesign share similar philosophies, which made them the logical partner for us. Their technology portfolio is impressive, and PMC reference monitors continually receive accolades from those who credit the designs with helping them achieve better mixes. We are pleased to have worked with PMC on the development of our RMS monitors and we feel strongly that the results speak for themselves.â€�
Available as the 5.5-inch two-way RM1 and the 6.7-inch two-way RM2, Digidesign say that the RMS monitors incorporate innovation in almost every aspect of their designâ€”from amplifier topology to acoustics and the deployment of advanced digital signal processing. Hereâ€™s a rundown of the key technologies in Digidesignâ€™s own words: Advanced Transmission Line Technology
Digidesign RMS monitors employ PMCâ€™s Advanced Transmission Line (ATLâ„¢) technology, which combines sophisticated cabinet engineering, proprietary drive unit and crossover components, and patented absorption materials to deliver enormous benefits over sealed and ported designs. As a result, Digidesign RMS monitors deliver improved audio resolution with a higher sound pressure level, reduced distortion, flat frequency response, and deeper, more defined bass frequencies than other speaker designs of similar size. And since the frequency response remains consistent at all volumes, there is no need to crank the volume in order to achieve maximum bass response. Bass Port Emulation
Although ATL technology provides a more accurate bass response than traditional ported designs, PMC and Digidesign engineers developed a unique Bass Port Emulation feature that allows the monitors to emulate the tonal characteristics associated with ported bass reflex speakers. As a result, the Digidesign RMS monitors make it easy to hear a mix as it truly sounds as well as how it translates to a ported speaker. With the Bass Port Emulation off, the frequency response is flat and free of any additional coloration. Onboard DSP Engine
Both monitors benefit from a 48-bit, fixed-point digital signal processing (DSP) engine that manages various tasks, including the monitorsâ€™ complex frequency crossover, speaker positioning EQ settings, trim level, and Bass Port Emulation.
The two-way, DSP-based digital crossover features revolutionary steep and pure filter designs that ensure an exceptionally clean transition, with virtually zero phase shift, between the two driversâ€™ response curves and roll-off rates. The net result is the ideal transition between the high frequency and low frequency drivers as well as superb phase response over a wider listening window. Superior, Analogue-Controlled, Class D Amplification
Each driver in RMS monitors is powered by independent, analogue-controlled, Class D amplifier, which combines the efficiency and size advantages of digital amplifiers with the precision, control, and sound quality of audiophile linear amplifiers. The power amplifier section within each speaker is 92% efficient in comparison with a linear Class A amplifier, which generally operates at around 50% efficiency. This means more power for the speakers and less escaping in the form of heat. And unlike typical Class D amplifiers that have a load-dependant frequency response, the specially-designed Class D amplifiers in Digidesign RMS monitors can sense the loudspeaker voltage directly and provide an extremely accurate frequency response regardless of the reactive load presented by the transducers.
Amplifier performance is further enhanced with the inclusion of a linear power supply, which provides two times the peak current headroom and better noise isolation than typical switch mode designs. RM1 and RM2 Specifications:
