PSP E27 is a multi-stage equalizer plug-in modeled after the famed analog E27 equalizer produced by Avedis Audio Electronics. PSP E27 offers three-band equalization with nine selectable frequencies in a standard 500x package.

This equalizer offers +/-16dB of control at musically selected frequency ranges, and offers gentle saturation. Low and high filters can work in bell or shelf mode with a single click. The E27 EQ is suitable for both mixing and mastering and offers additional preamp stage for global level control. This EQ plug-in also accurately emulates the nonlinear behavior of analog devices.

The additional PSP E27se (included in the bundle) is a simplified version of PSP E27. The PSP E27se is based on the same great audio engine, but it has a redesigned, simpler GUI making quick adjustments a snap. The PSP E27se is equipped with one E27 and one PA11 module.

PSP is the sole developer and manufacturer of the PSP E27. Functionality and sound of the PSP E27 have been approved by Avedis Audio Electronics. "TransDrive™" is a trademark of Avedis Audio Electronics. PSP is responsible for all customer support.
