Elysia alpha compressor

The Elysia alpha compressor is a Class-A stereo mastering compressor designed to deliver pristine, transparent results even at high gain reduction. Featuring feed forward and feedback modes, onboard parallel compression, M/S mode, and a soft clip limiter, the alpha compressor offers unmatched flexibility and precision for mastering engineers. With its smooth control behavior, audio filters, and tilt EQ, it provides creative control over dynamics while preserving the integrity of your audio.

Key Features:

• Class-A stereo mastering compressor with additional creative features
• Feed forward and feedback modes for varied compression characteristics
• Onboard parallel compression with mix control
• Tilt EQ for tonal adjustments
• Sidechain filter with blend function for frequency-dependent compression
• M/S mode for independent mid and side processing
• Soft clip limiter to prevent A/D converters from clipping

Additional Features:

• Feed Forward and Feedback: Switch between smooth feedback compression or strong feed forward compression with limiter settings
• Auto Fast: Automatically adjusts attack time for fast impulses, ensuring quick yet transparent compression
• Audio Filter (Tilt EQ): Adjusts the balance between high and low frequencies to quickly alter the sonic character
• Integrated M/S Matrix: Compress mid and side signals independently for greater control over stereo width and dynamics
• Soft Clip Limiter: Prevents digital clipping by rounding peaks instead of cutting them off, ensuring natural-sounding protection for A/D converters
• Parallel Compression: Blend compressed and uncompressed signals for dynamic control while preserving the original performance
• Passive Current Attenuator (PCA): Discrete transistors reduce unwanted fluctuations and add natural overtones, enriching the sound
• T16 Heater: Maintains constant temperature to ensure optimal performance of sensitive circuit components
• Matched Potentiometers: High-quality, stepped potentiometers with 21 steps ensure precise recalls, ideal for mastering applications
