Leema Corvus Single Channel (Mono) Amplifier
Available in black or silver
The Corvus is two products in one chassis: an intelligent mono slave amplifier and a studio quality stereo subwoofer controller. The slave amplifier section of the Corvus has exactly the same topology as one half of the Tucana and the Hydra and is therefore perfect for driving the centre channel in a multi-channel system of uncompromised audiophile quality.
The 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 bi-polar output stage, which can swing over fifty amps of current, ensures a vice-like grip and precise control of even the most esoteric centre channel loudspeaker.
The other side of the Corvus is a studio quality, comprehensive subwoofer control system. This section offers bass extraction, trim, filtering and phase control of mono, or uniquely: stereo subwoofers, in both multi-channel and stereo systems.
Once set up, the Corvus takes its commands from the Tucana via LIPS®. The input selection and volume controls tracks that of the controlling amplifier with the level indicated by the sophisticated volume display.
