elysia / alpha compressor

Compressor made by elysia. It uses an MS matrix circuit, allowing separate processing of the Mid and Side signals. It also features semi-automation of the attack/release characteristics that can be switched with a switch.

■The ultimate mastering tool

The elysia alpha compressor offers a step forward in the world of professional audio engineering. The alpha compressor is packed with innovative features that are technically perfect and uncompromising in terms of sound quality. These include MS processing, parallel compression, side chaining, audio filters, and more. The alpha compressor sets new standards in the world of mastering and allows you to explore any audio material even more deeply.

The newly developed circuit for the alpha compressor is of an ultra-high level that is difficult to find in any other equipment on the market today. All signal processing parts are individually operated with constant class A mode transistors, and discrete circuits are also used in the side chain and power supply. All parts are of the highest grade and have been carefully selected for their sound quality characteristics.

The sound produced by these uncompromising alpha compressors remains clean and powerful even in the most advanced and demanding use. In short, the alpha compressor is fully capable of meeting the demands of any musical genre, and provides users with an exceptional range of tools for mastering and recording that are unimaginable with existing compressors.

■Main features
・100% discrete analog
In addition to the 100% Class A discrete audio circuit, the power supply, side chain, and even the LED meter drivers are all specially designed using discrete components.

・M/S matrix function
In addition to the standard stereo mode, the MS matrix circuit allows you to process the Mid and Side signals separately.

・Feedforward and feedback circuit
You can choose between two types of compression operation: feedforward and feedback circuit. Two types of compression characters can be set for each channel with a single switch.

・Auto Fast function
Semi-automation function for switchable attack and release characteristics. This is a useful function that only responds to fast signals based on a value set by the user.

・Niveau filter
Intuitive audio filter. The Niveau filter allows you to effectively and easily change the character of your tracks.

・Sidechain filter
Filters the sidechain signal. This allows you to achieve frequency-specific compression without complex routing.

・Parallel compression
You can blend the dry and wet signals to your liking with a single knob.

・Monitoring circuit matrix
You can monitor the dry and wet signals on separate channels (L ch+R ch or M ch+S ch) with a simple button operation.

・Soft Clip limiter
Suppresses short and loud transients and smooths signal peaks to prevent clipping during AD conversion.

・Transformer circuit colorization
A transformer that can be switched on/off is built into the circuit, allowing you to color the sound with a transformer-specific sound.

・Analog Dynamic LED Meter
In addition to increasing and decreasing the LED meter, the brightness of the LED changes depending on the amount of reduction, so you can see the compression action continuously and smoothly.

・Passive Current Attenuator
The custom-designed gain reduction cell makes the alpha compressor incredibly fast, wide-bandwidth, and great-sounding.

・T16 Heater System
This system keeps the delicate elements of the discrete circuit at a stable temperature, preventing unstable operation.

・Stepped & Stereo Matching Potentiometers
All potentiometers are 23-step, and stereo matching is performed through a rigorous selection process using special software.

・VOVOX Sound Conductor Internal Wiring
There is no compromise on the internal wiring either. The use of VOVOX solid core maintains a vibrant, dynamic, and punchy sound.
