In order to accomplish this, it uses an uncluttered design approach. It has no tape loop, tape outputs, theater bypass or any other features to contaminate the signal path. The secret to the LA-01 preamplifier’s exceptional performance is found in its very high input impedance and near zero output impedance. The input stage uses a special differential amp input stage to produce the extremely high input impedance normally not seen in transistor designs. The output stage uses power mosfet transistors to drive any line preamplifier load without altering the units performance. The LA-01 power supply is housed in a separate enclosure that is a visual compliment to the pre- amplifier enclosure. The power supply is balanced and has four stages of decoupling to isolate it from the power line, making it seem like a battery powered unit. The rugged construction of the LA- 01 aids in providing a rigid structure to eliminate mechanical feedback vibrations. For example, the top and bottom covers are 1/4-inch thick aluminum, the side and rear panels are 3/8-inch thick aluminum, and the front panel is 1/2-inch aluminum. The enclosure is decoupled from its mounting surface with four STILLPOINTS feet. The LA-01 has four unbalanced stereo line inputs and two main stereo unbalanced outputs. The line stage has an ultra-low distortion high-input impedance direct-coupled amplifier with near zero output impedance. The output stage features power mosfet which can drive the power amplifier effortlessly to produce incredible dynamic sound. The Belles LA-01 preamplifier reproduces every detail of the music with clarity, openness, and sweetness. The LA-01 preamplifier provides the highest level of performance for the price. brochure_la01_preamp.htmlmanual__la01_preamp.htmlGallery/Gallery.htmlshapeimage_1_link_0shapeimage_1_link_1shapeimage_1_link_2
