In Every Professional Toolbox

The CDi Series of Crown® amplifiers are professional tools designed and built for installed sound applications. The series includes three models which are identical except for output power: CDi 1000, CDi 2000, CDi 4000 and CDi 6000. All are rugged and lightweight, and offer unmatched value in their class.

CDi-Series amplifiers feature an intuitive front-panel LCD screen to guide installers through their configurations. CDi amplifiers also offer onboard DSP for loudspeaker signal processing. Other features include a switch-mode universal power supply, useful function indicators, proportional-speed fan-assisted cooling, removable Phoenix-style inputs, barrier strip outputs for low-Z or 70V/140V loads, short-circuit protection and more.

General Features:
  • 2-Channel CDi Series Power Amplifier
  • Accurate, uncolored sound with very low distortion for the best in music and voice reproduction
  • Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults
  • Extremely versatile; rated for 2, 4, 8 ohms loads and 70V and 140V outputs
  • Intuitive front-panel LCD screen for quick, easy configuration
  • Switch-mode universal power supply
  • Onboard digital signal processing includes cross overs, EQ filters, delay, and output limiting
  • All products fill 2U rack spaces and weigh under 19 pounds

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
100 dB
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Input Sensitivity
This is the input sensitivity of the amplifier.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Voltage Gain
This is the voltage gain of the amplifier measured in decibels.
Cooling Options
These are the different cooling systems used in the amplifier to keep it cool.
Inputs
These are the type of input connections that the amplifier has.
Outputs
These are the types of output connections that the amplifier has.
