Audible Illusions L3A Line Stage with Remote with 1 Year Factory Warranty Brand New

Overview:

Many audiophiles remember how the introduction of the original Modulus preamplifier excited the audio industry. For the first time a full-function, reliable vacuum tube preamp with true high-end sound was available at an affordable price. It’s rare for a company to capture ones imagination and loyalty even once in such a manner. With the debut of the new L3A Line Stage the Legend Continues.

As many audiophiles migrated to CD and digital media for their main source we began producing our Modulus line stage series. These preamps were specifically designed to optimize digital playback and other line-level equipment. While the L3A retains the physical characteristics of its predecessors, it‘s not a rehashing of old ideas. The preamp is on the leading edge of audio technology. The L3A makes elegant use of engineering approaches to circuit board design that improves signal flow and reduce interference and vibration. A Class A, zero feedback, single-ended design built on the proven tube design philosophy that “simpler is better”. Additional improvements include dedicated relay signal switching and Teflon coupling capacitors which result in outstanding resolution. The L3A also features a dedicated external power supply which isolates AC fields from the main chassis and prohibits common-mode noise from interfering with the musical waveform.

In terms of features the L3A is an audio control center second to none. It has inputs and switching designed for CD, DVD, Tuner, External Phono Stage, Video, Aux and Tape. Volume and Muting functions are operated from the front panel or with Remote Control. The L-R Balance Controls are Precision Stepped Attenuators.

For Home Theater use the L3A includes complete input and output switching facilities for Surround Sound Processors. Another feature incorporates special active buffer circuitry for optimum matching of components which prevents signal degradation and impedance mismatches.

As with the previous Modulus preamplifiers, the L3A is next step in the evolution of our famous single-ended designs. The Heart of Fine Audio and Video Systems for Years to Come.

Control Functions:Master Stereo Volume, L&R Stepped Attenuator Balance Controls, Source-Tape, External S/S Processor, Mute and Power. Remote selects Stereo Volume Up-Down, Muting.Output Selection:Main (2) Tape, External S/S Processor.Optional Faceplates: Mirror-Polished Nickel-Silver Faceplates available as a special order.

Specifications:

L3A TECHNICAL FEATURES

• Circuit Design is Pure Class-A, Single-Ended Triode, Zero Feedback, Dual-Mono.
• Audio Circuit has no Cathode Followers or Buffers.
• To prevent unwanted AC-induced distortions, the L3 features an External Power Supply housing three separate supplies and a large-shielded, custom-wound transformer.
• In the main chassis, four-separate, fully-regulated FET power supplies drive the audio circuitry in addition to separate filament supplies.
• Automatic-timed muting with Tri-Color LED indicator.
• Low-light Illumination for Selector Switch and Master Volume Control Knobs.
• Standby Mode avoids cold starts and prolongs tube life and circuit components.
• Active Tape Output and External S/S Output Buffers are FET regulated, set for unity-gain.
• All circuit boards are hand-soldered using the finest silver solder available. All polypropylene and polystyrene film capacitors used are proprietary designs of Audible Illusions. Resistors are precision 1% Holco and Roederstein.
• Proprietary gold-plated RCA Jacks with Teflon insulators.
• Master stereo volume is laser-trimmed Alps. Balance Controls are Precision Stepped Attenuators.
• Handcrafted in the USA.
