Visitors to NAMM 2014 in Anaheim, California, which opens today and runs until January 26th, will have the opportunity to take a first look at the latest addition to reference monitor manufacturer PMC’s twotwo range of active nearfields.
The new twotwo sub1 is a low-distortion, active subwoofer featuring PMC’s unique ATL™ bass-loading technology, Class D amplification and DSP-based filtering and bass management, which extends bass output significantly with negligible harmonic distortion. The built-in amplifier delivers an impressive 400W of power to the sub, which has an active frequency response from a profound 22Hz up to 200Hz, and as with all PMC ATL™ designs, the tonal balance of the output remains consistent at all listening levels, from whisper-quiet to a stentorian blast. The sub1 can be deployed in a 2.1 configuration with twotwo series monitors to gain extra bass extension and headroom, or reproduce the low frequency effects (LFE) channel in a surround monitoring system.
The two long-throw bass drivers employed in the twotwo sub1 are a bespoke PMC design using natural materials, with a low-mass, ultra-stiff doped-paper cone to deliver unparalleled transient response. The elegant cabinet dimensions makes the twotwo sub1 easier to place than typical cube-shaped subwoofer designs.
The sub1 features an AES3 XLR input with a built-in high-quality sample rate converter, and can thus accept digital signals at any sample rate up to 192kHz. A pair of balanced stereo analogue inputs on XLRs is also available; switching between the sources is carried out from the rear panel or the optional desktop twotwo remote. The digital input is also passed through to the sub’s analogue and digital outputs for connection with other devices, allowing the twotwo sub1 to be used as a high-class D-A to drive other analogue monitors from a digital stream if required. Both analogue and digital outputs are always active regardless of which sources are selected. A single parametric equaliser is provided to assist with in-room alignment, and the analogue and digital outputs can be high-pass filtered to feed satellite speakers in a 2.1 configuration.
In addition to showing the now-complete twotwo range (twotwo.5, twotwo.5, twotwo.5, and the new twotwo sub1), PMC’s IB2 XBD Active midfields will also be in use at the PMC
