The Advantages of a Stereo System

Trance Audio has pioneered the use of stereo transducers in their systems for a number of years. There are a number of advantages to using a set of stereo Acoustic Lens transducers.

Stereo Imaging
The difference between a stereo and mono sound source from an acoustic guitar is quite striking. Panning the stereo transducers to the 10 and 2 o'clock positions yields a very naturla sounding representation of the instrument, providing much more depth and detail from the soundboard.

Even if you don't use a stereo setup for live performance, you will find that a stereos setup will prove invaluable for recording. The acoustic guitar recorded in mono is bland; that's why studios often us a stereo mic configuration to record the instrument. This adds essential depth and detail, giving the listener more of a sense of "presence" in the mix. Using a stereo Acoustic Lens setup provides the same enhancement with less external noise pickup than a mic setup; perfect for recording in less than pristine environments (apartments, rehearsal spaces, traffic-plagued neighborhoods, etc.), as well as in the best studio environment.

String and Tonal Balancing
Having separately controllable outputs rom a stere Lens system allows you ro precisely control the balance between the top and bottom strings of your instrument. Different venuew often emphasize different aspects of your instrument. Trying to control these anomlaies with EQ is difficult and will often introduce noise and phase problems as well. Separate control of the stereo Lenses will allow you to pull bak either transducer to prperly set the balance for changing acoustic conditions on the fly. This allows you to bring either element to the forefront, creating bold walking basslines or clear ringing treble string excursions; the choice is yours.

Spectral balancing
Separate outputs from the individual Acoustic Lens transducers also means complete control over EQ and effects usage. Using different equalization for each pickup can create deep, rich low-end response with a jazzy, muted upper-end, or any combination you can dream up. Chorus just the bass transducer while leaving the treble transducer clean and clear for expanded spatial effects, or apply a totally diffrerent reverb to each; the possibilities are endless.

Splitting the sensing area of the Acoustic Lens into two separate elements enables a successful installation even in problematic instruments. The tiny footprint of each Lens (1"x3/8") allows for easy mounting in smaller instruments, where amll bridgeplates and tight bracing make installtion of other transducers impossible.
