The RCK-527 features new features in classic opto-compression along with your choice of modern or vintage signal paths.
    Classic optoelectronic compression, upgraded signal path. The LA-2A and LA-3A are known for their unique music compression characteristics, but they do have some limitations. So we painstakingly recreated the more versatile RCK-527 compressor, bringing the workflow closer to that of the LA-2A and LA-3A while adding new features like a side-chain high-pass filter and parallel MIX control.
    RCK-527 uses our carefully designed output transformer, and then uses discrete components CLASS A amplifier module for amplification, making your sound full of modern clarity or retro tones.
