CROWN / DCi 4|600DA

600W x 4 (8Ω) power amplifier for high quality equipment. Dante compatible model. One unit supports both low impedance and high impedance, making it ideal for audio equipment that wants to use equipment installation space efficiently.

■Power amplifier, 4ch, 600Wx4, 2U, 9.2kg, Dante compatible

■Reduced installation space for power amplifier
- Drives 4 channels in a 2U housing. Ideal for audio equipment that wants to use equipment installation space efficiently.
-Each channel can be switched between low impedance connection and high impedance connection. Even if connection methods are mixed, there is no need to prepare a dedicated power amplifier.
- It also supports bridge mono output, so you can get a larger output.
■Standard support for digital audio network “Dante”
- Compatible with Audinate's ""Dante"" as standard. Multi-channel audio signals can be transmitted simply by connecting compatible devices with CAT cables, making signal distribution easy.
-Equipped with a redundant function that prevents audio from being cut off due to sudden problems such as cable breaks.
- Analog signals can also be input, and backup settings can be made to automatically switch to analog signals if Dante is interrupted.
■Can control and monitor multiple units at once from a PC
-You can centrally change settings and monitor operational status from Audio Architect installed on your PC. Since multiple units can be operated at once, necessary settings can be made efficiently. In addition, by customizing the software display screen, you can create an easy-to-use operating environment that suits your needs, and quickly identify occurrences of clipping, overheating, fluctuations in power supply voltage, malfunctions, etc. Furthermore, the general-purpose input/output (GPIO) terminal on the rear panel can be programmed with software, making it easy to link with other control equipment.
■Equipped with high-performance DSP, various audio processing can be completed in one unit
-Equipped with high-performance DSP, signal processing for the audio output system can be performed with a single amplifier.
■Equipment installation space can be greatly reduced even with a large number of output lines
- Up to 8 channels of amplification stages and signal processors housed in a 2U housing. Ideal for audio equipment that wants to use equipment installation space efficiently.
-Each channel can be switched between low impedance connection and high impedance connection. Even if connection methods are mixed, there is no need to prepare a dedicated power amplifier.
- It also supports bridge mono output, so you can get a larger output.
■Highly efficient design achieves low power consumption
-The power supply section is equipped with a highly efficient switching power supply and power factor correction circuit (PFC). It also reduces heat generation and saves electricity required to cool equipment during operation.
- When not in use, it can be set to sleep mode to keep power consumption below 1W. It can detect no signal and automatically enter sleep mode, or it can be forced into sleep mode using the terminal on the back panel.
■Uses the proprietary integrated circuit ""DriveCore"" at the heart of signal processing, improving reliability and sound quality
・DriveCore is a custom IC that integrates functions such as high-precision clock, modulation, error amplification, and feedback, which are the heart of an amplifier circuit, into a single chip. By installing this chip, we have reduced the number of parts by more than 500 compared to our previous products, while achieving excellent transient characteristics, detailed accuracy at low outputs, and precise tracking in the low range at high outputs.
■Equipped with convenient functions for fixed equipment
-Equipped with various protection circuits to protect the amplifier and speakers from sudden troubles.
-You can check the operating status in detail using the indicators on the front panel. Additionally, status signals can be output from the rear panel to confirm normal operation from a remote location.
-Equipped with a 21-step attenuator. Settings can be easily reproduced.
- Equipped with a variable speed air cooling fan to efficiently cool the inside of the main unit.
