The CNAMPX16X60 provides 16 channels of world-class audio amplification for the distribution of speaker-level audio to up to 8 stereo room zones as part of a complete Crestron Home audio distribution system. Brilliantly designed to complement Crestron's PAD8 audio distribution processors, the CNAMPX16X60 delivers a robust 60 watts per channel into 8 ohms, and 90 watts per channel into 4 ohms. Through the use of the optional CNXBRMO bridging interface, up to eight of the CNAMPX16X60's sixteen outputs may be bridged to produce 220 watts per channel into 8 ohms.

• Audiophile-grade 16 channel amplifier
• High-performance Class AB design
• Discrete high-current, bipolar output transistors
• 60 Watts per channel @ 8 ohms (full bandwidth)
• Up to 8 outputs bridgeable using optional CNXBRMO
• Twin MOH-core toroidal transformers with bifilar windings
• Separate power supply for each stereo output
• Convection-cooled modular component design
• Opto-coupled output protection | Inrush current limiting
• Sophisticated control and fault monitoring via Cresnet
