Klein + Hummel M 52, M 52 D

Klein + Hummel’s M 52 miniature active control monitor (pictured) is an update to the M 51. It features a 3-inch driver, and its built-in amplification is said to be capable of producing more than 100 dB. The compact monitor weighs 5.7 pounds and is designed for situations in which space is at a premium, such as small studios, broadcast vans and mobile rigs.

The M 52 offers volume and power controls on the front. The M 52 can be AC powered (at 85 to 230 volts) or DC powered by a 12- to 20-volt battery via a 4-pole (QQQ pin?) XLR connector. The M 52’s magnetic shielding and a solid, resonance-free, aluminum enclosure allow it to be placed next to a computer monitor or disk drive. It features a transformer-balanced +6 dBu XLR analog input and can be mounted with optional hardware to almost any surface at any angle, as well as rackmounted.

Identical to the M 52 in every other way, the M 52 D adds D/A conversion, with S/PDIF and AES/EBU digital inputs that synchronize with any signal between 32 and 48k Hz at 24-bit resolution. An input-selection knob on the front panel switches the M 52 D’s input signal between analog, digital left and digital right, and both digital channels can be combined.

Klein + Hummel will show the M 52 at the NAB show in Las Vegas, from April16-19, in booth #N7117.
