Corvus

The Corvus is essentially two products in one chassis; an intelligent mono slave amplifier and a studio-quality stereo subwoofer controller. 

The amplifier section of the Corvus is effectively one half of the Tucana and is therefore perfect for driving the centre channel in a surround system of uncompromised audiophile quality.  This groundbreaking mono design uses three heavy-duty toroidal power transformers, one for the power amplifier, one for the sub controller, and one for the central processing unit (CPU).  This, coupled with a refined multi-bipolar output stage, which can swing over fifty amps of current, ensures a vice-like grip and precise control over the most esoteric centre channel loudspeakers.

The other side of the Corvus is a comprehensive, studio quality,  subwoofer control system. This section offers bass management, where the low frequency content of the centre, front and rear channels are fed to the subwoofer controller, together with the normal LFE channel where present.  Level trim, filter frequency and phase are fully adjustable for mono, or uniquely, stereo subwoofers.  The bass management system may be used in both multi-channel and stereo systems.

Once set up, the Corvus takes its commands from the system master via LIPS®.  The input selection and volume controls automatically track that of the master with system level indicated by the sophisticated volume LED ring display.
