503 3-BAND EQ
500 SERIES SOLID STATE EQ FOR TRACKING, MIXING, MASTERING
Mastering quality tone shaping from LaChapell Audio.
EQ’s come in all flavors, but sometimes you need a near colorless equalizer, and the 503 is it. The LaChapell 503 500 series EQ sports a very low distortion signature with minimal phase deviation, which translates to musical clarity. Perfect for tracking, mixing, or mastering, the 503 is extremely clear and transparent. With a 24dB range on each carefully selected band plus switchable frequency high and low pass filters, the 503 is an incredible tone shaper.
Use when tracking to capture the essence of your source, or on mix down to make tracks sit perfectly in the mix. Because there is little phase interaction the LaChapell 503 can be used subtly or aggressively.

503 MK2 RAVES & REVIEWS
““So, to the point! Do I like this EQ? yes I do. I love Scott’s work and the 503 is no exception to his talent! The LaChapell Audio is another awesome tool any engineer could use in a heartbeat. This is not a surgical EQ, but isn’t heavy-handed with coloration, but it sure is smoking sweet! A big double thumbs up from the pan man EQ!” – Ronan Chris Murphy
