PMC’s QB1 Active (QB1-A) is a large-scale, ultra-high-resolution main studio monitor with analog and digital (up to 192kHz) inputs. Ideal for either soffit-mounted or freestanding use, each QB1-A incorporates the latest generation of PMC’s driver designs, Class-D amplification, Advanced Transmission Line (ATL) bass-loading technology, DSP control, and a quartet of 10in. carbon fiber/Nomex piston bass drivers. With a maximum SPL of 132dB at 1 meter, each of the QB1-A channels has an expansive 4825W of Class-D amplification at its disposal (275W on the HF driver, 550W on the midrange, and 4000W on the four bass drivers), and the latest iteration of PMC’s ATL technology ensures low-frequency response down to 20Hz. The cutting-edge onboard DSP provides driver unit optimization, EQ, and sophisticated crossover networks, while the wired RJ45 desktop control provides user-friendly access to user EQ settings via its backlit display and jog wheel, with the ability to store up to four user setup presets. At 1092x82x520mm (WHD), the QB1-A will retrofit into almost all existing studio soffits.
