L5 Reference Stereo Preamplifier
Following in the BSC design tradition, the L5 preamplfier represents a different approach to conventional preamplifier architecture.
The L5 preamplifier utilizes a multi-chassis solution for noise and crosstalk reduction, all consolidated on its own custom designed platform. The (i) Power Supply, (ii) Control System, and (iii) Audio Circuitry are separated into individual machined aluminum enclosures.
- The Power Supply is based around massive, but separate, internal Analog and Digital power sections. The L5 preamplifier remains stable even in the most challenging electrical environments.
- The Control System is located in a physically separate command module that houses the following key control interfaces: volume control, remote control, input selection, RC5/RS232, LED display, and other basic control interfaces. This separation significantly reduces the occurrence of parasitic noise or other similar interference.
- The Audio Circuity is physically isolated in a 3rd separate chassis, which is electrically and mechanically disconnected from the other two chassis.
All three enclosures are centrally located on a solid aluminum base, minimizing the overall space requirements.
The L5 preamplifier relies on Discrete, Complimentary, Direct coupled, Differential and Class A circuitry from input to output to ensure the very best in signal transmission speed and accuracy.
At the heart of every preamplifier is the volume control, and to this end, BSC Audio pulled out all of the stops to create an incredibly accurate and mechanically stimulating linear volume control. Based on a precision R2R resistor network, volume position is selected via the motorized linear slide mechanism. The volume control offers 255 quarter-decibel steps to make finding the perfect listening level much more simple.
The L5 is a perfect complement to any audio system but in particular to our M5 or S5 amplifiers where it transfers the speed, dynamics and sense of palpability fully realized only through a BSC Audio Class A playback system.
