The Crown CDi 4000 is the flagship amplifier of the CDi line, which is identical from model to model except in terms of wattage. It is a stereo, dual channel amplifier, capable of producing a maximum of 3200 watts when bridged and put into monaural operation, or 1600 watts per channel when operating in stereo mode and driving a pair of 2 ohm speakers. This is more than enough power to satisfy the requirements of nearly any club, church, or studio. Additionally, the CDi 4000 is capable of operating under power of 70 or 140 volts.

In the most demanding audio applications, you may find it necessary to make customizations to your sound, and the CDi 4000 is equipped with 20 user-selectable presets allowing you to dial in the tone of your choice. Additionally, if you connect the CDi 4000 to your computer using compatible HiQnet software, you can drill down into the details of these presets and manually customize the levels of equalization, limiting, crossover, and delay to your liking. Additionally, HiQnet functionality allows the CDi 4000 to interface with the other devices in your studio, or you can simply disable it and turn DSP off entirely, if you wish.

In addition to its world class tonal quality and power, the CDi 4000 is equipped with extensive fault protection circuitry. The CDi series was the first series of amplifiers by Crown to be modeled on computers using Crown's proprietary Icepak technology, enabling engineers to examine the thermal characteristics of the CDi series before they began being produced. This has resulted in one of the lightest (at 19 pounds), most thermally efficient power amplifier lines ever to be created. The CDi 4000 is cooled using a forced air induction system, which automatically shuts the amplifier off and alerts the user if overheating ever occurs due to a blocked vent or improper installation. The CDi 4000 is completely protected even in the event of user error, thanks to Crown's three year, no fault warranty.

Crown International provides some of the most sought after audio amplification in the world, and has been doing it since 1947. Crown powers the live sound of some of the world's most popular touring bands, and is so desired that many groups specifically state on their performance contracts that the venues in which they perform must provide Crown amplifiers. Crown CDi 4000 Power Amplifiers take this legendary sound and bring it to the world of installed sound applications, including studio monitoring systems, places of worship, public address systems, and meeting halls.
