The NAD CI 940 Multi-Channel Power Amplifier is a high-performance, reliable, and flexible component that can easily provide the instantaneous peak current required for good bass response. It is incredibly flexible, with selectable local or global inputs and the ability to bridge channels to create a single high-power channel, and is designed to drive real world speaker loads, not just simple laboratory test loads.

NAD CI 940 Multi-Channel Power Amplifier

High-performance four-channel amplification for custom installation and distributed audio systems. With multiple discrete high-power output devices in the component, it can easily provide the instantaneous peak current required for good bass response.

RELIABLE, FLEXIBLE, EASY

The reliability, flexibility, and ease of installation of the CI 940 is unsurpassed. Its design is space-efficient and will fit into standard racking units with rack ears and Phoenix speaker connection blocks. The amplifier is fully protected from short circuit and overheating, and automatically restores operation after a condition is rectified. The CI 940 is incredibly flexible, with selectable local or global inputs and the ability to bridge channels to create a single high-power channel.

EFFICIENT WITH LOW NOISE AND DISTORTION

Choose between a DC trigger or a signal-sensing turn-on with auto shut-off to make integration easy. The signal sensing circuit employs a sophisticated music sensing circuit to prevent the false triggers common with noisy source components or other types of interference noise like RF leakage or ground loops.

AWARD-WINNING SONICS

When it comes to sound, NAD is in the top tier of all amplifier brands, consistently winning awards for both performance and value for money. Known for their warm, expansive and intensely musical sound, NAD amplifiers are designed to drive real world speaker loads, not just simple laboratory test loads. The NAD CI 940 will bring out the best performance from any speaker giving you the best possible listening experience. It is also very quiet with inaudible residual noise in no-signal conditions, important when using efficient speakers in small spaces. Energy efficiency is also impressive with <0.5W standby consumption and highly efficient power delivery. Musical, practical, efficient and reliable, the CI 940 is everything you want for high quality distributed audio.

Measure what you buy.
Size: 50 Feet, Style: 10 AWG
I love the product made my job easy on this last pontoon I worked on but the pontoons only 20 ft long and I only pulled wires halfway and I got less than 10 ft left there was not 50 ft on that spool. But now that I've cut it used it and are using it a little hard to complain, but the use of the application for the wire is 100%, thank you very much for the product.

Great value, but not overly flexible.
Size: 50 Feet, Style: 10 AWG
I used this wire to run power from my car's battery to a ham radio in my trunk, and an inverter under my driver seat. This wire fit the bill perfectly. It is water, oil resistant, and tinned (to resist corrosion). One challenge I ran into was its stiffness. Despite having many fine strands, the wire doesn't flex well. You can bend it, but wants to spring back and doesn't hold its shape. This made running the wire under the hood through the firewall, and along the door moulding... a LOT of work. I scraped a lot of knuckle in the process. Overall, I'd still recommend using it for automotive projects. It is a high quality wire. Just know that it's hard to manipulate though a lot of twists and turns.
