Designed to be entirely uncompromising, the ULTIMA preamp is a world-class solution with cutting-edge proprietary technology. It benefits from true dual-mono construction with separate ultra-high-frequency power supplies for each channel, giving the best possible separation. With the addition of Chord Electronics’ low-noise circuitry, noise floor performance is exceptional, at beyond -135dB.
The ULTIMA preamp includes three pairs of fully balanced outputs and three unbalanced outputs; inputs include four unbalanced and four balanced with six-step gain adjustment; selection is made via remote control or from the front panel, which uniquely features separate frequency EQ adjust controls for the left and right channels.
Internally, each of the power supplies and the sensitive volume, balance and EQ controls, are surrounded by solid milled aluminium shielding to prevent RF interference. Fully balanced A/V bypass circuitry allows direct connection to A/V processors. Further features include defeatable front panel VU meters with BBC ballistics, two low-distortion, low-noise front-panel headphone output jacks and 12V remote triggering outputs.
