  1. Crown K1 Stereo Power Amplifier with 4 Planet Waves gold speaker cable adapters. 1500 Watts.

    $600 + UPS insured shipping to USA only. PayPal OK.

    Also Includes these $60 worth of adapters to enable use with Speakon, 1/4”, binding post and banana speaker cables:
    2- Like New Planet Waves Female Speakon to Banana gold speaker cable adapters.
    2- Like New Planet Waves Female 1/4” to Banana gold speaker cable adapters.

    K1 is in near mint, Like New Operating Condition with a few touched up very fine marks from rack mounting. Inspected and all functions tested with no issues. All original with no repairs. I am the first owner and purchased it new from an authorized dealer.

    It comes in the original box/packing including: Operation manual, proof of performance report and product registration sheet.

    With very low hours of use in my non-smoking home in a stereo bass guitar rig, I am selling it as I never seem to get the chance to play anymore.

    The picture showing the clipping indicator lights lit up is just Crown's design where they light up for a moment at power up.

    MSRP $2,387. I paid $1,400 for it on sale.

    Info from Crown Audio:
    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 750 watts per channel at 2 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
    • Soft Start (Keeps amp from drawing large currents when first turned on)
    • Switchable Input Sensitivity (1.4V or 26dB)
    • Mono mode switches: Bridged, Y (parallel) or both (for daisy chaining)
    • Balanced XLR and 1/4" inputs
    • 5-way binding posts
    • Channel 1 and Channel 2 gain controls with notched settings
    • LEDS: Thermal (Warns of need to dissipate heat), Clip (Warns of distortion in the amp), IOC (Input / Output Comparator: Warns of distortion at 1/30th the level of clipping by comparing the actual waveforms of the input to the output), Signal (glows when output signal is present), Enable (Indicates Power status)
    • Frequency Response: +/- .25 dB for 20Hz - 20kHz
    • Power Output (per Channel): 750 watts into 2 Ohms, 550 watts into 4 Ohms, 350 watts into 8 Ohms
    • Bridged (mono) power: 1500 watts at 4 Ohms, 1100 watts at 8 Ohms
    • Signal-to Noise (A Weighted): >100dB below rated power
    • Damping Factor: >3000 from 10 to 400Hz
    • Input Impedance: Nominally 20KOhms balanced, 10KOhms unbalanced
    • Passive convection cooling allows amplifier to drive 2 Ohm load at 8db into clip in 104 degree environment!
    • Power Supply can configure to 100, 120, 200, 220, 230, 240, 250 VAC at 50 or 60 Hz
    • Heavy duty 2’ power cord
