The first thought that comes to mind when listening to the phrase optical compressor is no other than the old and unique Urei LA3A! Our goal was to create an optical compressor with such simplicity, capabilities and warmth but at a compact size and the result is the Zipper!
The hand-selected optical element provides auto adjustable Attack and Release, depending on the signal’s strength and amplitude. Select between Hard and Soft ratio from a dedicated toggle switch, Hard being 10:1 and Soft being 4:1 compression ratio.
Can be used as a maximizer or clean booster with the compress control up to 9 o’clock.
At high compress settings the sound becomes punchy and percussive perfect for “Gilmourish” licks, funk and chicken picking styles.
A high-end Pro-Audio compressor at your feet!
