CPA 2500

Six Input Signature Preamplifier

When routing and attenuating signals, a Chord preamplifier both has flexible input and output options, and delivers the purest audio experience with absolutely no colouration and minimal distortion.



Range: Chord Signature
Colour options:

The CPA 2500 is our entry-level preamp and represents the most affordable way into Chord pre/power ownership. A full-width design and the perfect complement to our SPM 650 power amp, the CPA 2500 allows the direct connection of up to six ancillary devices via its unbalanced RCA inputs. For high-performance connections and longer cable runs between pre/power amps, the CPA 2500 is equipped with two pairs of balanced outputs and one pair of unbalanced RCA outputs. Although suitably minimalist in its configuration, the CPA 2500’s balanced output amplifier section utilises a highly accurate, high-performance design, capable of delivering the transparency that Chord amplification has become internationally known for.

The unit can be controlled manually, or via the supplied remote control handset.  A front-panel vacuum fluorescent display shows input source selection and volume control functions, which are displayed digitally with figures from 00 to 98. The fascia features balance and motorised ALPS volume controls, input, and output selection BUS switches and a remote IR sensor. Further features include two separate monitor inputs and outputs, for monitoring/recording to CD-R/RW, DAT etc.

As with all our products, the CPA 2500 is hand-crafted from aircraft-grade aluminium to exacting standards, giving a superb rigid construction, unsurpassed vibration-damping and stunning aesthetics.
