Chord Electronics Ultima Pre 2 Preamplifier
The Chord Electronics Ultima Pre 2 Preamplifier adds nothing to the original waveform and instead preserves it with zero colouration.
This is thanks to their latest advances in switch-mode power supply design, developed from aerospace technologies, and the ultra-low-noise proprietary solid-state circuitry which is both carefully shielded and equipped with premium system components. As a result, the ULTIMA PRE 2 is able to achieve unprecedented noise floor performance of -130dB, meaning your source will always sound like your source and nothing else.
Where connectivity is concerned, the ULTIMA PRE 2 has hi-fi systems (and more!) covered.
Featuring eight inputs, four stereo pairs of XLRs for balanced connections and another four RCA for unbalanced connections, each of these can be gain-matched and individually selected. For outputs, a single stereo pair is available via XLR or RCA, to accommodate a single stereo amplifier such as the ULTIMA 5 or a pair of mono blocks such as the ULTIMA 3s.
Naturally, headphone users are catered for, too, for personal and late-night listening with the addition of a high-resolution 6.35mm output on the front fascia.
Where system-triggering is important, (allowing the simultaneous start-up of connected equipment from a single button-press), the ULTIMA PRE 2 Reference Preamplifier is equipped with three outputs which should be more than enough for most systems.
