We live in a digital age. Today's studios require monitors with the option of a digital input. Because of its unique compactness, the M 52 was a natural candidate for use in digital applications. With many editing suites and audio workstations today, digital output signals are commonplace, so equipping reference monitors with digital input connectors and integrated D/A converters makes sense.
M52 + Digital Input = M 52 D
We took the M 52, expanded upon the existing design, equipped it with switchable inputs for both analog and digital signals in AES3 (AES/EBU), AES3id and S/P-DIF format, and christened the new model the M 52 D. The D/A converter has 24-bit resolution and a sampling rate of 32 - 96 kHz. The analog input is transformer-balanced and floating. A rotary switch on the front panel allows you to select from four sources: the analog input, digital left, digital right, or both digital channels combined.
Power switch, volume control, and the signal selection switch are all conveniently located on the front panel of the compact cabinet. The rear panel hosts an XLR connector which can accept either the analog signal or the AES/EBU digital signal, and a BNC connector for an AES3id or S/P-DIF digital signal, which makes for easy daisy-chaining. Other connectors, including battery input, are located on the back panel.
A Variety of Digital Applications
Magnetic shielding fitted as standard makes the M 52 D is an excellent match for digital audio workstations, or as a control monitor with a digital mixing console or switcher. Compact dimensions of the M 52 D allows for use in many other application areas, such as video editing suites, multimedia projects, surround-sound systems, broadcast vans, and compact rack-mounted systems. In addition, the ability to switch easily between digital and analog inputs means the M 52 D can be implemented wherever a precise control monitor is required.
The all-aluminium enclosure offers maximum interior volume. Added rigidity from inner wall bracing ensures an absence of resonant colorations. The 75mm (3") broadband neodymium driver performs remarkably for an enclosure of this size, delivering an accurate, smooth response and low distortion across the entire pass band.
The M 52 D offers the same flexible mounting options as the M 52. The LH 11 desktop stand allows optimal workstation placement and mounting and the MA 19 allows for rack mounting.
