Radio Design Labs' ST-EQ3 is a unique audio equalizer in the STICK-ON product series by Radio Design Labs. The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-EQ3 offers the ultimate flexibility in audio bandwidth adjustment, with the big PLUS...you can put it right where you need it.

The ST-EQ3 features a balanced bridging input, which may also be connected unbalanced, if desired. The output driver is 150 ohm balanced, and is intended to drive unbalanced or balanced lines of 150 ohm or higher impedance. Equalization is accomplished by three active circuits, each controlling a separate audio band. These bands were carefully selected to yield a module that works effectively in a wide variety of systems. Each band's center frequency can be either boosted or attenuated by at least 12 dB. The Q of the low and high band equalizers was selected so that those controls can be functionally considered as a total bass band or treble band control. The midrange control is optimized to voice-band adjustment, with the overlap tailored to provide smooth operation for wide band music applications.

A feature unique to the ST-EQ3 is the CLIP indicating LED. When audio signals are equalized, the boosted level can cause the output circuit to clip. Or alternatively, if prominent frequencies are attenuated, the input is likely to be turned up so that its amplifier can clip. In either event, there is a risk of distortion. Unlike many products which show only input clipping, the ST-EQ3s CLIP indicator flashes if either the input or output stages will clip!
