Overview

Warm Audio WA 2A is the remake of Classic Boutique Teletronix LA2A Style opto compressor with Kenetek T4B module, for a fraction of the price.

Featuring the classic opto-compressor designs that date back to at least the late 1950’s, this particular remake is loved by artists around the world.

The WA-2A is a high-voltage, Class-A opto-compressor, utilizing large-core CineMag USA Transformers, four premium vacuum tubes, and the legendary Kenetek opto-cell - considered by many to be the world’s finest. 

Features
  • '2A Style, Transformer balanced, high voltage, opto tube compressor: - No plug-in or another compressor type quite compares to the warm, forgiving, fluid qualities of this classic '2A-style optical compressor. For decades, the renowned ‘2A style circuit has become the go-to device for seamlessly handling vocals, bass, and a wide variety of other instruments and program material in an effortlessly smooth way.
  • Completely discrete, all-tube signal path: -  A quick look inside and you will find the WA-2A sports an all discrete, class-A, all-tube circuit, using only through-hole components on a hand-populated board. The WA-2A has a robust power supply to deliver current to its four vacuum tubes, a socketed Kenetek T4B module (optical attenuator), and large custom transformers by CineMag.
  • Historically accurate 4-tube circuit: - The WA-2A operates on four tubes: two 12AX7’s, one 12BH7, and one 6P1J.  Tubes used are Tung-Sol and Electro-Harmonix brand tubes in the signal path, which sound very 'open' and LARGE.  All 4 tubes are socketed for easy swapping and replacement. Warm Audio WA2A Opto Analog Compressor Tubes
  • Utilizes premium grade input and output CineMag USA Transformers: - Cinemag Transformers have been a part of the professional audio industry for past 60 years. True experts in the field, brings out the best of WA 2A

  • Utilizes USA made Kenetek opto attenuator: -  There is no T4B module finer than those made by Kenetek, and Warm Audio proudly offers this high-end module in WA-2A.

  • XLR and TRS balanced line level inputs and Output: - On WA2A, you get Balanced outputs and inputs with 600 ohms impedance.
  • Socketed to allow for retrofitting with other opto-cells: -  For those who wish to experiment; we have built our unit in accordance with the standard octal socket and wiring configuration used for optical compressors for the past half-century. If you have an old stock T4A, T4B, or T4C module that is in good working order, or a new one made by another manufacturer; you may install it in the WA-2A to experiment with different types of modules.

  • Variable Pre-emphasis: -  This control adjusts the sidechain audio that directs the optical module to compress. When moved counterclockwise, the WA2A will become less responsive to high-frequency transients.

  • Stereo-link capability: - This control allows you to operate two WA2A units in stereo mode with the same threshold. Amazing isn't it?

    Performance and Recommendation 

    The WA-2A, as with any classic optical compressor, appears deceptively simple at first, with so few controls on the front panel. The attack, release, knee and ratio controls found on many other types of ‘fully comprehensive’ compressors are absent; leaving the user only with a control for compression threshold (Peak Reduction), makeup gain (Output Gain), and a selection of compressor or limiter, which changes the ratio from a starting position of about 4:1 to something closer to 100:1. The WA-2A’s attack and release characteristics, as well as its ratio and knee, are determined by a very complex relationship between the optical attenuator and the audio signal being fed into it. Generally, the WA-2A’s attack will be very fast, with its release character being a rather complex, multi-stage event that, to an extent, is determined by the audio input and the immediate history of the audio passed through the module (known as its ‘memory effect’). Generally, the initial release will be very fast, with a second, more subtle stage of release taking one or more seconds, and a tiny third stage of release taking even longer. Due to its extended and smooth time constant, this type of compressor became famous for taming bass guitar, upright bass, and vocals; however, it has the attack speed and transparency to actually handle many other types of instruments. As with all things audio, let your ear determine what the music needs and how much compression is enough to achieve your desired goals. Due to the amount of compression that can achieve; this type of compressor is often the first choice for instruments that require a fairly strong amount of gain reduction, such as bass; and also often the first choice for more advanced studio techniques such as series and parallel compression.Warm Audio WA2A Analog Compressor With High Quality Components

    Series compression is simply following one compressor/limiter with another one; they do not have to be the same make or model, but they can be. This is done sometimes when one compressor is doing much of the heavy lifting of dynamic control, while a second compressor is added because the engineer favors its particular tonal qualities or ‘glue’. In the case of classic optical compressors, some engineers have been known to set one unit to a heavier amount of Peak Reduction in Compress mode, and follow it by the second unit with a much more modest amount of Peak Reduction, set to Li it mode. This is done to level off any residual transient peaks not caught by the first unit. 

    Parallel Compression involves using two compressors side by side working on the same input signal. They do not have to be the same make or model compressor, but they can be. The advent of digital audio workstation (DAW) recording actually lends itself quite well to this technique. It is now very easy to duplicate a track in the DAW and send each copy out to individual hardware channels simultaneously, with no real signal loss. As with series compression, one unit will generally be set much more aggressively than the other, and the two compressed tracks can be blended back together in the DAW to achieve the desired effect. When performed properly, one can give a source both the intensity and presence of a hyper-compressed track, while still retaining the openness, apparent dynamics, and detail of an uncompressed track. The WA-2A is an ideal choice for this type of compression, due to the very high levels of gain reduction it can achieve.

    A simple setup with WA2A would look something like this

    Reviews

    "I must add... in a song that is so involved instrumentation-wise, the Warm Audio WA-2A allows the Lead Vocal to finally have a happy spot in the song.  It no longer has to battle and fight the other frequencies and instrumentation to be heard.  The WA-2A now gives the vocal its own space in the track where it is nice and strong and sits perfect!!"

    ~Michael Lattanzi

    "This unit is just fantastic, a big step up from my summit TLA-50. I have wanted an LA2A for 25 years but could never afford one and you guys have made that dream a reality, thanks for this wonderfull piece of gear. It will be used in my home studio every day."
