The CP 3000S offers 2 x 1600 watts into 2 Ohms at 8.15 kg, the CP 2200 provides up to 2 x 1100 watts into 2 Ohms and suits full-range and larger concert-sound systems, and the CP 1800 supplies up to 2 x 900 watts into 2 Ohms.
Electrovoice CP Series — buyer FAQs
What is the Electrovoice CP Series and what is it designed for?
The Electrovoice CP Series is a line of linear power amplifiers built for demanding live audio applications. Grouped under the Precision Series Compact Amplifier banner, the range uses a Class-H design that reduces heat generation and allows a substantially smaller chassis without sacrificing output. Models cover subwoofer drive, full-range cabinets and mid/hi speaker systems, making the series broadly applicable across professional sound reinforcement.
What output power and weight figures do the individual CP Series models offer?
The CP 4000S flagship delivers up to 2 x 2100 watts into 2 Ohms and 2 x 1500 watts into 4 Ohms from an 8.7 kg package. The CP 3000S reaches 2 x 1600 watts into 2 Ohms at 8.15 kg. The CP 2200 provides up to 2 x 1100 watts into 2 Ohms, weighing 16 kg with a conventional transformer supply, while the CP 1800 supplies up to 2 x 900 watts into 2 Ohms.
Which CP Series models use switch mode power supplies and why does it matter?
The CP 4000S and CP 3000S both use switch mode power supplies, which is the main reason they achieve particularly low weights of 8.7 kg and 8.15 kg respectively despite their high output figures. The CP 2200 uses a conventional transformer supply and weighs 16 kg. For applications where transport weight is a consideration, the switch mode models offer a meaningful practical advantage.
Who makes the CP Series and where does it sit within the Electro-Voice range?
The CP Series is made by Electro-Voice (EV), an American professional audio manufacturer with a long history in microphones, loudspeakers, amplifiers and signal processing for sound reinforcement. The CP line sits within EV's Precision Series Compact Amplifier family, covering multiple power tiers from the CP 1800 up to the CP 4000S flagship, targeting both touring and installation professionals.
What should I check when buying a used Electrovoice CP Series amplifier?
Confirm which specific model you are buying, as output power and weight vary considerably across the range. Check whether the unit uses a switch mode or conventional transformer supply, and verify that both channels operate correctly at rated loads. Units covering subwoofer duty will have seen heavy use, so test thermal management and protection circuits.
