M-Audio BX-5 Studio Monitors

FEATURES: The rear panel of the cabinet reveals a bass port and input connectors on both balanced jacks and XLRs, governed by a single volume control. Power connection is through the usual IEC socket and the power switch is also mounted on the rear panel. A three-way Acoustic Space slide switch corrects the bass end for proximity to boundaries by offering 2dB or 4dB of shelving low cut. The bass response may also be adjusted directly by selecting 56Hz, 80Hz or 100Hz roll-off values via another slide switch. A further switch allows the high end to be set flat, boosted by 2dB or cut by 2dB, and there's also a Presence in/out switch to add mid-range boost. A fixed, steep sixth-order filter (36dB/octave) is used to suppress frequencies below the handling range of the speakers, so as to prevent excessive driver excursions. A matched M Audio active subwoofer is also available SPECIFICATIONS: Type: 2-way near-field studio reference monitors Low-frequency drivers: 5.25 in. magnetically shielded mineral-filled polypropylene cones, high-temperature tolerant voice coils and damped rubber surrounds High-frequency drivers: 1 in. swivel-mounted natural silk domes incorporating magnetic shielding, ferro-fluid and internal damping technologies LF Amplifier Power: 38W (EIA RS-490 dynamic power) HF Amplifier Power: 38W (EIA RS-490 dynamic power) Crossovers: 4th-order Linkwitz Riley for smooth frequency response Crossover Frequency: 3kHz Low-frequency rolloff: 6th-order filter optimizes maximum driver excursion Input Connectors: XLR balanced, TRS balanced/unbalanced Input Sensitivity: 85 mV pink noise input produces 90dBA output SPL at one meter with volume control at maximum Input Impedance: 20k ohms balanced, 10K ohms unbalanced Protection: RF interference, output current limiting, over temperature, transient on/off, subsonic filter, external main fuse S/N Ratio: > 100dB below full output, 'A' weighted Frequency Response: 56Hz - 20kHz Power indicator: Power on/off indicator on front panel Power Requirements: 115V/~60Hz or 230V/~50Hz (selectable); power via detachable 3-conductor line cord Dimension: 9.85 in.
