The LT has two laser beams pointing from the left and right shoulders of the groove for tracking. Two other beams read the stereo sound at 10 microns below the shoulder. To effectively manage older and more warped records, an additional beam regulates the distance between the laser head and the surface of the record. The laser reads audio information untouched and undamaged by a needle and plays it on the groove without any digitization.
The laser moves to the wall of the groove and back. The reflection angle is transferred to the audio signal, whereby the LT maintains analog sound throughout the entire process. As a result, the LT cannot differentiate between an audio signal and dirt on the record. Since the LT has no contact with the record groove, no coloration is added, which makes the audio reproduction as commensurate as possible with the sound of the master tape. Because the LP is in a drawer and the laser reads only the groove, there is no acoustic feedback or sound alteration. Only the music on the groove can be heard on the playback system or CD transfer.
In some cases, the LT can even play broken records when all the pieces are placed on a tray without tape or glue. Additionally, it can play warped records of up to five millimeters in deviation. As it includes an analog noise blanker, there is a reduction in pops and clicks. This feature may be turned off while restoring old recordings. The laser can also read below the depth of surface scratches, which improves playback. If the vinyl or the recording itself is lacking, however, the LT can do little to alter the sound.
The LT will not play clear or colored records that are transparent, as the laser beams must reflect from an opaque surface in order to be read. Vertical-cut records and those with rounded-groove shoulders will not play as well. Overall, the LT operates like a CD player; it includes the usual scanning, skipping, and repeating functions, and it scans records to identify the "bands" present. There is even a "hover" button that permits the player to repeat a single groove segment. The record sustains no damage when the LT is in hover or pause mode.
