Introduction

Congratulations on your purchase of a new Carver Professional Power Amplifier. It is backed by state-of-the-art engineering and manufacturing techniques to bring you the best in quality craftsmanship and reliable performance. The pm700 and pm950 are specially designed for pro sound applications. Their rugged construction and low profile make them ideal for sustaining the abuses of the road with reliability and space-saving economy. And their accurate sound and ample power make them ideal for critical studio applications as well. The pm700 is rated at 350 watts per channel into 4 ohms and 225 watts per channel into 8 ohms. In bridged mono operation it is rated at 700 watts into 8 ohms. The pm950 is rated at 475 watts per channel into 4 ohms and 325 watts per channel into 8 ohms. In bridged mono operation it is rated at 950 watts into 8 ohms. The sophisticated protection circuits designed into these amplifiers will protect your system should an unexpected fault occur.They also protect the amplifiers from excessive temperature, continuous current limiting and shorted outputs. The balanced input uses a high quality, high common-mode rejection differential amplifier for exceptional hum and noise rejection. The sequencing feature allows a rack of amplifiers to be powered up from a remote location. The daisy-chain connection scheme causes each amplifier to turn on in sequence, preventing the l a rge in-rush current that can occur when an entire rack of amplifiers is turned on s i m u l t a n e o u s l y. These power amplifiers were designed and manufactured by people with a lifetime commitment to providing the world’s finest components for music and sound reproduction. Thanks for placing your confidence in Carver Professional. We know your amplifier will provide many years of dependable s e r v i c e and reliable sound reproduction.

Unpacking and Paperwork

Carefully unpack the amplifier and keep the original carton and packing materials for future moving, shipment or long-term storage.
