CPA 2500 preamplifier
Introducing the entry level CPA2500 Pre-amplifier. The Chord CPA 2500 is of minimalist design but utilises a highly accurate, high-performance balanced output amplifier section. It is operated manually or via the remote control handset and has an unbalanced line level source selection unit for selecting and adjusting the signal levels of up to 6 unbalanced input signal sources and is for use prior to the main high power amplification of a quality hi-fi system.
The CPA 2500 is a full width design with matching style and character to the SPM 650 Power amplifier. The open airy sound of the CPA 2500 is instantly recognisable to anyone familiar with Chord Electronics power amplifiers. The CPA 2500 is transparent and flexible in its ability to ??1??7disappear??1??7 within the music. Full display and remote control features enable total mastery over the six unbalanced inputs.
The unit features two separate monitor inputs and outputs. Monitoring (Tape, DAT, CDR) is possible from any source to either of the tape recorder outputs. The CPA 2500 has been configured with 2 input selector buses, each bus connected to one monitor output. The CPA 2500 comes fully equipped with two pairs of balanced and one pair of unbalanced outputs. The output stage has been specially designed to perfectly match any Chord Electronics power amplifier. Six pairs of RCA phono style unbalanced inputs are configured for two CD players, one VCR or DVD player, one Radio or Tuner& two recording output monitors.
These controls can be manually or remotely operated. The volume control is displayed digitally with figures from 00 to 98 with a logarithmic law. The balance control also has an indication for the direction of travel.
As with all Chord products each piece of metal work is machined from solid aluminium giving a superb rigid construction that gives unsurpassed vibration damping with stunning looks to match.
British chords CPA 2500
The British chord Chord has implemented the concept of excellent sound and color in the entry-level Hi-End stereo sound product, and launched two new sets of CPA 2500 pre-amp and SPM 650 post-amp.
The front stage of CPA 2500 has two separate input/output lines, which can be connected to all source equipment, and allows users to switch between A/B two sets of different signal sources at any time. The back panel has a total of 6 groups of unbalanced RCA Phono input terminals, corresponding to CD players, VCRs, DVD players, etc. The output is two sets of balanced XLR terminals and three sets of unbalanced RCA. The SPM 650 rear and power amplifier have flexible power output performance, and can choose 130 watts / 8 ohms, 170 watts / 4 ohms, or 200 watts / 2 ohms formats. It uses Chord''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s exclusive dual-die MOSFETs and Dynamic Coupling technology to transmit clean, clear and excellent sound quality. Because CPA 2500 and SPM 650 are 100% matched by Chord in appearance and characteristics, they are very suitable for users to choose at the same time.

Chord Electronics (hereinafter referred to as Chord), a British company, can be considered far-sighted. When it was founded in 1989, Chord started by manufacturing switching power amplifiers. Switching power supply should be the most widely used power supply in the world, and its traces are common in computers and home appliances. But is it used in audio? And it is the high-end audio that pays great attention to texture? Chord should be considered the instigator. As early as 1989, founder John Franks told everyone: Time will prove that we are right. More than ten years have passed in a blink of an eye, and today Chord''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s webpage still says: Time will prove we are right. Does this mean that switching power supplies are actually not that amazing, so everyone still doesn’t believe it? No, Chord has been operating well for more than a decade, and John FrankS is always neatly dressed and vigorous every time he appears. The Abbey Road studio in the UK is still Using countless Chord amplifiers to drive their monitor speakers, it can be seen that many people affirm their work. However, it is still so difficult to get rid of the prejudice of the general audio fan towards the switching amplifier. How to get rid of the prejudice against switching power supply? To be honest, I used to look at Chord''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s amplifiers with "colored eyes". But after listening to their works a few times, I have no doubt about the switching power supply. It should be said that I have no doubts about the "well-designed and manufactured" switching power supply. Of course, Chord''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s switching power supply is what I think is "good design and manufacture".
