Crest Audio Ci Overview

The 2RU Ci 30 x 4 Multi-Channel Power Processing Amplifier from Crest Audio is designed to drive low-impedance or 70V speaker loads without bridging between channels. Bridged operations are supported for additional power into 8Ω loads or 140V operation. This amplifier features 4 channels. Channels may be selected as low impedance or 70V individually. The 30 x 4 amplifier is protected by Tour Class protection. It has front and rear panel indicators for amplifier status. There is one controlled-voltage input per channel standard, and one fault relay per channel standard. This amplifier has a sequential turn-on standard, Euro-style input connectors, and barrier strip output connectors. The module bay is provided to input Nx module bay accessories for full amplifier control and monitoring via NexSys 4 software or MediaMatrix product and digital audio distribution.
