Overview
The Celto Pro D48 is a digital loudspeaker management processor engineered to deliver absolute signal purity and precise control for professional sound reinforcement systems. Featuring a 4-input and 8-output architecture, alongside 2 stereo AES/EBU digital inputs, the unit is powered by a high-performance 64-bit floating-point SHARC DSP engine.
Operating at a 96 kHz sampling rate with 32-bit ESS SABRE Reference converters (120 dB dynamic range), it ensures exceptional audio fidelity. The electronically balanced and RF-filtered Neutrik™ XLR connectors guarantee interference-free signal transmission in demanding environments. Network control is seamlessly managed via TCP/IP compatible 100 MB RJ45 Ethernet. Built for reliability, the D48 features a low-noise, long-life SUNON™ Maglev™ cooling fan and a secure PowerCon power connector, all housed in a compact 1U rack chassis, making it an ideal choice for both permanent installations and touring applications.
