Summit Audio Dual Tube Leveling Amplifier (TLA100A)
The Summit Audio TLA-100A Tube Leveling Amplifier offers a classic amp design with a harmonious blend of old and new technologies. The result is a compression device with the incredibly warm and smooth sound of vacuum tubes without the inherent disadvantages of older designs.
Summit Audio has been making the TLA-100A for decades and it produces a much sought after sound that has been used on literally thousands of records and in live sound venues around the world. The TLA-100A leveling amp uses a soft-knee and program dependent transition characteristic and a transformerless signal path, resulting in a set-and-forget compressor that always sounds right with a minimum of knob fiddling.
With all the changes that nearly a quarter of a century has made in the audio industry, the popularity of Summit Audio's TLA-100A Tube Leveling Amplifier has yet to wane. The TLA-100A is a classic design with a technological hybrid of vacuum tube and solid state devices. The harmonious blend of old and new technologies produces the incredibly warm and smooth sound of vacuum tubes combined with the reliability of solid state.
Compressing in a musically satisfying way is easy with the TLA-100A; the incredibly forgiving circuit design makes it almost impossible to make it "pump and breath." When fast transient signals are being sent to the TLA-100A, the unit reacts quickly both in attack and release, when the signal has a slower rise time, the attack and release times automatically react more slowly resulting in a set-and-forget compressor that always sounds right with a minimum of knob fiddling. Try it on vocals and bass, also great for kick drum and guitars. The TLA-100A really shines for tracking and mixing individual instruments and is linkable with another TLA-100A for stereo signals.
