Klein + Hummel O 410 Monitors

Klein + Hummel is introducing its O 410 mid-field monitors at the 123rd AES convention in New York City (booth #418/Demo Room #2D01). The O 410 is a tri-amplified three-way loudspeaker designed specifically for use in music, broadcast and post-production studios for tracking, mixing and mastering.

The O 410 features magnetically shielded drivers: 10-inch bass, 3-inch soft dome midrange and 1-inch tweeter. The drivers are powered respectively by 340-, 160- and 180-watt hybrid Class A/B amplifiers. The high-capacity vented enclosure extends bass response down to 34 Hz, even at high output levels. The use of Klein + Hummel’s LRIM (Low Resonance Integral Molding) material helps avoid structural resonances in the cabinet. A waveguide featuring Mathematically Modeled Dispersion (MMD) reduces negative effects associated with the loudspeaker’s interaction with the room.

A dedicated midrange driver promises low harmonic and intermodulation distortion, as well as clean audio reproduction. The monitor’s design promises low self-generated noise and allows rotation of the waveguide to permit usage in either vertical or horizontal formats. The cabinet accommodates an optional grille and an extensive set of accessories for installation and mounting.

An electronically-balanced analog input is fitted as standard. A transformer-balanced input and a 24-bit/192kHz digital input are both available as options. The digital input can accept AES3, AES3id and S/PDIF signals. It also has XLR and BNC digital inputs, and a BNC digital output. Class-H amplification techniques reduce power consumption when signal levels are low.
