Klein + Hummel, a 100% Sennheiser subsidiary, introduces a new monitor speaker, the O 410 midfield monitor. The O 410 has magnetically shielded drivers: 10" bass driver, 3" soft dome midrange, and 1" tweeter. The respective drivers are attached to 340, 160, and 180 Watt hybrid class A-B amplifiers. Class H techniques reduce power consumption when signal levels are low. The high-capacity vented enclosure cleanly extends the bass response down to 34 Hz, even at high output levels. The most important part of the frequency spectrum is reproduced by a separate midrange driver resulting in extremely low harmonic and intermodulation distortion and a clean sounding audio reproduction.
Various input options allow the O 410 to be used with any source equipment: electronically-balanced analog input fitted as standard, optional transformer-balanced input, and an optional 192 kHz, 24-bit digital input. The digital input can accept AES3, AES3id, and S/P-DIF signals. XLR and BNC digital inputs, and a BNC digital output give flexible and robust interconnectivity. Flexible acoustical controls adapt the monitor's response to compensate for the loudspeaker's environment: bass, low-mid and treble controls for specific and common acoustical issues, and a parametric equalizer for additional low-frequency corrections. The electronics can be remote located when the cabinet is flush mounted, and can be remotely powered on with two modes of operation (0 V and 12 V trigger).
