CROWN / DCi 2|600 Power Amplifier

A high-quality 600W x 2 (8Ω) power amplifier for professional installations. Because it supports both low and high impedance connections in a single unit, it's ideal for audio equipment installations where efficient use of space is crucial.

The DCi Series Analog reduces the installation space required for power amplifiers in systems that need multiple audio output lines. The DCi 8|300, the highest-channel model, features eight output channels, delivering 300W (4Ω) per channel, for a total of 2,400W, from a 2U chassis. It also supports bridged mono output, allowing for even higher output. Each channel can be independently switched between low-impedance and high-impedance connections. Even with mixed connection methods, there's no need for dedicated power amplifiers. Furthermore, high-impedance connections allow for direct driving of the constant voltage transmission line, eliminating the need for external transformers.

The DCi Series Analog reduces power consumption, saving on operating electricity costs. The amplification section employs highly efficient Class D operation. The power supply section features a switching power supply and power factor correction (PFC) circuit, achieving class-leading low power consumption. Low heat generation also reduces the electricity costs associated with cooling. Additionally, it includes an Auto Standby function that reduces standby power consumption to less than 1W. If no signal is detected for more than 30 minutes, the unit automatically switches to standby mode. It can also be forced into standby mode via an external contact.

The DCi Series Analog employs a proprietary integrated circuit, ""DriveCore,"" at the heart of its signal processing, resulting in improved reliability and sound quality. DriveCore integrates high-precision clocking, pulse width modulation, error amplification, and feedback functions onto a single chip. This reduces the number of parts used by over 500 compared to our previous products, improving long-term reliability. Simultaneously, it achieves excellent transient response, detailed accuracy at low output levels, and precise low-frequency tracking at high output levels. It achieves an S/N ratio of over 108dB, providing superior sound quality.

The DCi Series Analog features various protection circuits to shield the amplifier and speakers from sudden malfunctions. Furthermore, the front panel indicators allow for detailed monitoring of the operating status. Additionally, a status signal is output from the rear panel for remote confirmation of normal operation. The input is equipped with a 21-step attenuator. When using a high-impedance connection, the output voltage can be selected from 70V and 100V, and a 35Hz high-pass filter is automatically inserted. A variable-speed cooling fan is included to effectively cool the inside of the unit.
