Alice 538R: Overview and Features

The Alice 538R stands as a mains-powered 1U rack-mounted iteration of the acclaimed 538T OPTO stereo compressor, featuring distinctive functionalities tailored for audio professionals and enthusiasts.

Key Features:

  1. Opto Compression Design: Incorporates Ted Fletcher’s renowned opto compression design, renowned for its historical significance and exceptional audio performance.
  2. Enhanced Compression Capabilities: Allows for a wide range of compression ratios, ranging from gentle to aggressive, ensuring versatile and precise audio compression.
  3. Accurate UV Compression Metering: Utilizes a real meter for precise UV compression metering, ensuring accurate and detailed monitoring during the compression process.
  4. Extreme Stereo Width Control: Offers extensive stereo width control, allowing users to manipulate the stereo image’s width for creative audio effects.
  5. Side-Chain Functionality: Equipped with a side-chain input, enabling precise control and manipulation of the audio compression process.
  6. Hand-Matched Audio Transformers: Ensures quality and shielded audio transmission via hand-matched OEP canned transformers, enhancing audio fidelity and clarity.

Mechanical Specifications:

  • Compact 1U rack-mounted design utilizing mains voltage for reliable operation.

Inputs & Outputs:

  • Utilizes Left and Right transformer-balanced inputs and outputs via hand-matched OEP canned transformers.
  • Side-chain functionality available through a 6.35 mm stereo TRS connector.

Width Control & Metering:

  • Implements a unique ‘sum and difference’ mode for precise stereo equalization without image shift, allowing accurate width control.
  • Features easy-to-read stereo analogue meters, reading audio (UV) or compression depth (comp).

Technical Specifications:

  • Inputs: 10K impedance differential balanced.
  • Outputs: Floating balanced 50 ohms with a maximum balanced output of approximately +26dBu.
  • Gain: Maximum 24dB.
  • Noise: Maintains at least 80dB below operating level, exceeding a dynamic range of 100dB.
  • Harmonic Distortion: Generally within 0.005%, with a rising 2nd order harmonic distortion at lower frequencies under compression.
  • Frequency Response: Line in 20Hz to 20KHz within 1dB.
  • Audio Crosstalk: Utilizes M/S processing with variable ‘side’ content via the width control, offering exceptional L/R crosstalk.

Compressor Specifications:

  • Operates as a photo-resistive servo-operated feedback type compressor, with a variable ratio of approximately 1.2 to 1 up to 8 to 1.
  • Sidechain filtered for precise bass compression, with adjustable attack and release times for customized audio control.

Connections & Power:

  • Connections via Neutrik XLR and TRS connectors.
  • Powered by 85 to 285v AC, housed in a 19″ 1U rack-mount unit, supplied with a 2m IEC cable.
