Affordable Classic Electro-optical Compression The original LA-3A Audio Leveler made its debut in 1969 and was an instant hit. Studio engineers loved the half-rackspace solid-state electro-optical compressor for its simple 2-knob operation and the punchy, program-dependent dynamics control it delivered on electric bass, guitar, and just about any other source. GearNuts knows every studio needs a '3A, and we have great news. The Golden Age Project COMP-3A Jr joins its big sibling in re-creating the circuitry, sonics, and behavior of the classic — and it's even more affordable! Housed in a rugged quarter-rackspace chassis, the vintage-style COMP-3A Jr circuit uses no ICs. The I/O is transformer balanced. And the sound? Warm and deliciously musical. Treat yourself to classic compression, with the Golden Age Project COMP-3A Jr.Discrete circuit path The Golden Age Project COMP-3A Jr circuit is based on a venerable design that uses an integrated optocoupler to control gain.
