Crown K1 Amplifier

Crown K1 Amplifier Description

The Crown K1 Amplifier is the first amplifier to take advantage of Crown's new Balanced Current Amplifier technology. This technology yields extremely efficient power amplification, with the K1 producing much less heat - even while clipping - than typical amplifiers.

Crown K1 Amplifier at a Glance

• Balanced Current Amplifier technology ensures thermal stability without a fan!
• Delivers 350 watts at 8 Ohms, up to 1500 watts (bridged) at 4 Ohms
• Incredibly flat frequency response for compromise-free audio

Massive power with one tenth the heat!

The K1 amp from Crown is the first amplifier to take advantage of Crown's new Balanced Current Amplifier technology. This technology yields extremely efficient power amplification while generating just one-tenth the heat of conventional amplifiers. In fact, the powerful K1 Amplifier can deliver an amazing 750 watts per channel into 2 Ohms (and that's a very solid 2 Ohms)! As a result the amp can put out clean, uncolored power without the use of a fan. No fan means the K1 runs quietly and cleanly, takes up less space in a rack and requires less maintenance. The K1 also boasts advanced circuitry protection that guards against DC, mismatched loads, internal faults and high frequency overloads. Crown is so confident of the K1's stability that it's backed by a three-year no fault warranty!

Power to spare, no matter what your configuration

The Crown K1 Amplifier is rated to deliver 350 watts per channel at 8 Ohms, 550 watts into 4 Ohms or 750 watts per channel into 2 Ohms. In addition, in bridged mode the K1 has a capability of 1100 watts at 8 Ohms or 1500 watts at 4 Ohms - all while running without a fan! The K1 is cool, clean and quiet.

Legendary Crown frequency response

Crown amps have a long history of providing crystal-clear audio response in critical listening situations, and the K1 Amplifier is no exception. Flat frequency response: (+/- .25 dB) from 20Hz to 20kHz ensure you get out of the K1 exactly what you put into it!

Crown K1 Amplifier Features
