All the legendary sonics of the renowned Helios Type 69-500 pre/eq module neatly packed into the convenient and cost-effective 500 series format!
The Helios Type 69 500 holds true to the original Dick Swettenham design, but with a number of modern updates such as 5db steps on the mic preamp gain switch as opposed to the original 10db steps, additional 16khz EQ frequency selection for today's high-bandwidth digital recordings, and a balanced output for easy interfacing with any digital converter.
