Features

Overview: The Crown CDi1000 is a 2 channel power amplifier designed for installed sound applications, providing accurate, uncolored sound with low distortion and capable of powering 2, 4, and 8 Ohm speaker loads or 70V and 140V speakers. Other features include; an intuitive front-panel LCD screen for quick and easy configuration, onboard digital signal processing that includes crossovers, Eq filters, delay, and output limiting, switch-mode universal power supply, and advanced protection circuitry to guard against shorted outputs, mismatched loads, and overheating.

Inputs/Outputs: Inputs consist of two 3-pin Phoenix connectors, that can accept either a balanced or unbalanced line-level input. The speaker output is a 4-position barrier strip that can be configured for 2 channels, in Dual mode, or a mono output in Bridge mode.

Power Rating: The CDi1000 features a flexible output that can power 2Ω - 8Ω loads, in Dual mode, and 4Ω - 8Ω loads in Bridged-mono mode. 70V speakers can be used in Dual mode and 140V speakers for Bridged-mono mode. Power ratings are as follows:

Level Controls: The front panel is equipped with two independent rotary Level (Gain) controls that allow optimal signal level to be set in conjunction with the LED level indicators.

LED Indicators: The power amplifier features two 6-segment LED strips that provide various information about the amp. Each strip has the following LED's:

• Thermal: Lights red indicating whether the Thermal Protection circuit has been activated (When internal temperature exceeds 176˚F/80˚C).
• Clip: Lights red when the signal reaches the threshold of distortion.
• -10dB: Flashes green when the signal level reaches 10dB below the clip point.
• -20dB: Flashes green when the signal level reaches 20dB below the clip point.
• Signal: Flashes green when a very low-level signal is present on that input channel.
• Ready: Lights green when the amplifier is ready to produce audio.

DSP Options: The CDi1000 offers several DSP processes such as crossovers, Eq bypass, delay, 70V mode, and output limiting, which are accessed using the front panel LCD screen and the three navigation buttons: Sel/Enter, Prev/Up, and Next/Down. Settings can be modified and stored as a preset with 19 user presets available. The DSP options are as follows:

• Output Mode:
  • 70V: Sets 70V mode for channel 1 and 2.
  • High Z: Channel is configured for 70V/high-Z loads.
  • Low Z: Channel is configured for low-Z loads (2, 4, or 8 Ohm speakers).
• Input Mode:
  • CH1 + CH2: Signals on channel 1 and 2 are summed together and fed to both output channels.
  • Input Y: Channel 1 input goes to both channel 1 and 2's outputs.
  • Stereo: Channel 1 input goes to channel 1 output and channel 2 input goes to channel 2 output.
• XOV (Crossover): The available crossover frequencies are: OFF, 90Hz, 100Hz, 1200Hz, 1500Hz, 2000Hz, 2-CH SUB, CUSTOM.
• EQ (Equalization for Ch.1 and Ch.2): Options are: OUT and IN. When IN is selected, the equalization that you set up in the System Architect software is applied to the signal. OUT bypasses equalization.
• DEL (Delay for Ch.1 and Ch.2): Delay times are: OFF, 1-10 msec, 10-50 msec, and 0 sec. The 0 sec option is a placeholder for any delay time set in the System Architect software.

USB Input: The back panel includes a USB-B input which allows you to use Harman's System Architect software to edit the DSP functions of the CDi1000.

Cooling: With a rear-panel cooling fan, the CDi1000 employs flow-through, front-to-back ventilation for rapid, uniform head dissipation.

Protection Systems: The CDi1000 incorporates a number of protection features which include:

• Output Current Limiting: This circuitry protects the amplifier output stage from damage caused by short-circuit loads.
• DC Protection: Shuts down the amplifier in the event of an output DC offset exceeding 2V.
• Thermal Protection: This will activate if the internal heatsink temperature exceeds proper operating temperatures (176˚F/80˚C).
• Non-Touch Cover: A shock-proof plastic cover is provided to protect the speaker output terminals from being shorted.
• Attenuator Security Covers: The front panel level controls can be removed, once proper levels have been set, and snap-in security covers can be installed to keep the levels from being adjusted.

Power Supply: The CDi1000 utilizes a switch-mode universal power supply, eliminating the need for voltage converters when using the amp in other countries.
