Chord Electronics CPA 5000 Preamplifier

The CPA 5000 is one of two ultra-high-performance models in the flagship Reference range, representing our finest preamp engineering.

The CPA 5000 contains the latest proprietary ultra-high-frequency power supply. When combined with our ultra-low-noise circuitry, the technologies give the CPA 5000 an incredible noise floor performance of below -130dB.

The CPA 5000 is highly flexible. It offers four pairs of fully balanced inputs, four pairs unbalanced inputs, plus two completely independent tape/recording loops. Each input has six levels of gain that can be individually selected to prevent large changes in volume when switching between inputs and all settings are stored via a microprocessor, even if power is removed.

The CPA 5000 also includes two low-distortion, low-noise front panel headphone outputs to exploit the full potential of today’s high-quality headphones and give added flexibility for late-night or personal listening.

Also included, is fully balanced A/V bypass circuitry for direct connection to A/V processors, 12V remote triggering outputs at the rear of the unit to activate power amplifiers or A/V processors on power-up, plus Chord’s legendary aircraft-grade solid aluminium casework.
