  • FS: Proton AA-1660 [email protected] power amp

    I'm offering for sale a spare multichannel power amp made by Proton, which had an excellent reputation for making good power amps before getting out of the business. This model manufactured in the early 1990's and it still works great today. This is a great way to get in to an active multiway speaker system with outboard crossovers.

    Up to two pairs of channels can be bridged to give 150W channels, so you operate with 4,5, or 6 channels.

    PROTON AA 1660 six-channel amplifier specifications:
    • Rated output: (20Hz ~ 20KHz) 60W @ 8 Ohm; 150W @ 8 Ohm (Bridged)
    • Total harmonic distortion: <0.05%
    • Intermodulation Distortion: <0.01%
    • Damping Factor:> 100
    • Frequency Response: (20Hz ~ 20KHz) +-0.5dB
    • Bandwidth: (total harmonic distortion < 0.1%) 10Hz ~ 50KHz
    • Input Sensitivity: 1.0Vrms
    • left and right channel separation: (@1kHz) 60dB
    • signal to noise ratio: 113dB
    • Dimensions: 42 (W) x12 (H) x39.5 (D) cm
    • Weight: 12.6 kg
    • power consumption: 700W max

    I can post or Email pics of the actual item, but it basically looks like this:

    I'm asking $240 + shipping from 95616. Shipping weight is about 30 lbs. Local pickup OK. Guaranteed not to be DOA.

    PM and/or post reply if interested.
