NAMM 2014: PMC unveils twotwo sub1

PMC has provided a first look at the latest addition to the reference monitor manufacturer’s twotwo range of active nearfields.

The twotwo sub1 is a low-distortion, active subwoofer featuring PMC’s 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 400W of power to the sub, which has an active frequency response from 22Hz up to 200Hz, and as with all PMC ATL designs, the tonal balance of the output remains consistent at all listening levels. The sub1 can be deployed in a 2.1 configuration with twotwo series or in a surround monitoring system.

The sub1 features an AES3 XLR input with a built-in 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, and both sets of inputs are always active regardless of which sources are connected; 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. 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.
