The three-way IB2S-AII offers discerning users all the attributes of PMC's large ATL reference active monitors but in a more compact form. They are ideal for high-end reference monitoring in both stereo and surround formats. The DSP-controlled, Class-D powered cabinets make use of PMC's ATL (Advanced Transmission Line) bass-loading technology, providing a smoothly controlled, high-resolution low-frequency response. Each cabinet features PMC's hand-built preparatory drivers - the 10-inch carbon-fibre/Nomex piston, 75mm fabricdome mid, and the 34mm soft-dome tweeter. The power is supplied by PMC's ultra-low distortion devices that are conveniently rack mountable, providing HF 275W, MF 550W and LF 1200W of acoustically transparent power. This single cabinet monitor features user-adjustable HF and LF shelving filters, ±8dB input level trim, and an AES3 digital input, as standard. The input sensitivity of the balanced analogue inputs can also be adjusted from +4dB to +16dB. In addition, the EQ, level trims and analogue/digital input election settings can be adjusted from a distance using an RJ45-connected remote, which is supplied as standard.
