D-TAR Equinox Three Band Parametric Equalizer with Notch Filter

Seymour Duncan and Rick Turner have joined forces to design gear. The EquinoxTM is a low-noise 3 band parametric equalizer and preamp, equally suited for both studio and live use. The frequency sweep control, bandwidth control, and boost/cut control provide musicians with the means to correct - or enhance - very specific tonal problem areas.
Another very useful feature is the dual notch filters; they're very narrow-band EQ points that can be used to control or eliminate acoustic feedback. In testing this unit, we were amazed by how little the notch filters affected the overall tone - at first we thought our test unit might be broken! However, we intentionally created feedback, and discovered that they were effective in "notching out" the problem frequencies and reducing/killing the feedback. Cool!
Features
- 3 Band Parametric Equalizer Preamp - Allows precise EQ control to correct or enhance very specific tonal problem areas with frequency sweep control, bandwidth control, and boost/cut control
- Two independent notch filters - Eliminate acoustic feedback

- True bypass switching of non-activated functions - Bypass switch removes entire EQ and notch filter sections from signal chain leaving only high impedance, low noise input and buffered output
- High quality components - Extremely low noise and distortion, audiophile quality sound
- Mute switch - Allows complete shut off of rig
- 1/4 stereo input jack - Allows connecting input and output to Solstice on a single, stereo cable
- Compact, portable design - Can be used as a stand-alone preamp for ultra portable instrument amplification systems
