Introducing Radiator, a dual drive tube input channel and EQ, based on the classic Altec 1567A tube mixer from the 1960s. The original Altec 1567A hardware was a rack-mounted five-input tube mixer with removable transformers, a simple two-knob EQ, an unmistakable green faceplate, and a whopping 97 dB of gain. The sound, by today’s standards, is colored and gritty, with a heaping helping of good old fashioned hardware noise. In its day, it was used on many early Motown hits, and found its way into the PA racks of countless churches and school auditoriums across the USA.
