The MB-185 Series II Signature monoblock offers the same technological improvements and cosmetic refurbishment as its bigger brother, the MB 450 Series II, although in this case using 6550C tubes and a more compact output transformer to make 220 watts per channel in tetrode mode. The extensive updates to the Series II amplifier include a revised power supply, SmartTube technology with automatic bias adjustment and fault sensing, and upgraded electronic components. The result is an amplifier with improved dynamics, superior speed and transparency at the top end. The MB-185 Series II is ideally suited for use with planar or electrostatic speakers as well as dynamic speakers with 10-inch or smaller drivers. Specifications: Tube complement: 6 x 6550c, 1 x 12AT7, 1 x 12BH7. Output power (20 Hz–20 kHz into 5 ohm load): Tetrode mode = 220W, Triode mode = 110W. Input sensitivity (220W, Tetrode): 2.0V. Input impedance: 42k ohms. Optimum Load Range: 4 - 8 Ohms. S/N Ratio @ 220W Tetrode/Triode: -110dB, 120Hz. (2) Inputs: 1 x single-ended (RCA), 1 x balanced (XLR). Remarks: Signs of wear which include aesthetic issues such as minor scratches and minor dents. |
