Neve 2264ALB Limiter/Compressor Module

Under the Hood: AMS Neve 2264ALB Mono Limiter/Compressor

Introduction

The AMS Neve 2264ALB is a remarkable 500 Series limiter/compressor module that stays true to the original 2264A’s legendary sonic characteristics while introducing some new features. Crafted in England by Neve engineers, this module retains the classic architecture, matching components, and original hand-wound transformers, ensuring that it delivers the authentic Neve dynamic sound that producers and engineers have come to rely on. Let’s take a closer look at the features and capabilities of this versatile audio tool.

Design and Construction

The 2264ALB’s design is based on a diode-bridge limiter/compressor, offering a high-headroom Class A/B configuration that provides a wide range of tone-coloring options. It incorporates transformer-coupled circuitry in the input, bridge-driver, sidechain, and output stages, contributing to its exceptional sound quality and performance.

Limiter Section

The module features two chains for controlling the level control element: one for compression and the other for limiting. The limiter has a selectable attack time of 4ms, making it ideal for moderately percussive material like solo piano recordings. The limiter threshold can be adjusted between +4dBm and +15dBm, offering control over the limiting action’s intensity. Additionally, the Limit Recovery control provides various recovery times for the limiting action, including an Auto mode for automatic corrective action after peaks.

Compressor Section

The compressor section offers five preset ratios: 1.5:1, 2:1, 3:1, 4:1, and 6:1. The control characteristic ensures a smooth and progressive onset of compression, reaching the true ratio at approximately 6dB above the threshold. The threshold can be set from -20dBm to +10dBm, providing a wide range of compression effects. Using low ratios with a low threshold can preserve the dynamic range while improving the signal-to-noise ratio during recording. On the other hand, higher ratios with a high threshold can result in partial limiting action.

The Features of the Neve 2264ALB Limiter/Compressor Module

• Authentic Neve Sound: Crafted in England by Neve engineers, the 2264ALB retains the unique sonic characteristics of the original 2264A. It uses the same architecture, matching components, and original hand-wound transformers, ensuring a faithful re-creation of the classic Neve sound.
• Dual Functionality: The module features two chains controlling the level control element – one for compression and the other for limiting. This provides flexible dynamic control options for various audio applications.
• Limiter Section: The limiter offers a selectable attack time of 4ms, making it suitable for moderately percussive material such as solo piano recordings. The limiting threshold can be adjusted between +4dBm and +15dBm, providing control over the limiting action.
• Compressor Section: The compressor provides five preset ratios: 1.5:1, 2:1, 3:1, 4:1, and 6:1. The control characteristic ensures a smooth and progressive onset of compression, reaching the true ratio at around 6dB above the threshold. Threshold settings range from -20dBm to +10dBm, offering a wide range of compression effects.
• Signal Presence Indicator: The module features an LED indicator with approximate PPM ballistics that displays gain reduction levels from 0dB to -20dB. This allows for easy monitoring of the compression effects on the signal.
• Slow Attack Option: The 2264ALB introduces a new Slow Attack option, expanding its versatility. This feature is ideal for bus compression and other applications where a slower attack time is desired.
• Transformer-Coupled Circuitry: The module incorporates transformer-coupled circuitry in the input, bridge-driver, sidechain, and output stages, ensuring exceptional sound quality and performance.
• Bypass Switch: A bypass switch is provided, allowing you to completely remove the circuit from the signal path when not needed.
• Integration with Neve 1073 Series: The module can be combined with the Neve 1073LB microphone preamp module and 1073LBEQ to create a complete Neve channel strip. A 3-way INS Link cable connects these modules, establishing an all-new Neve classic audio path in the same 500-series rack.
• VPR-Alliance Compliant: The 2264ALB is designed to be compatible with most 500 Series chassis, adhering to the VPR Alliance, an industry standard for 500-series modules.
• High-Headroom Class A/B Design: The module’s design provides a high-headroom Class A/B configuration, offering a wide range of tone-coloring options.
• Versatile Application: The 2264ALB is suitable for a variety of audio processing tasks, ranging from subtle compression to more aggressive limiting, making it an essential tool for audio engineers and producers.
• Threshold Range (Limiter): +4dBm to +15dBm
• Attack Time (Limiter): 4ms (Selectable)
• Recovery Times (Limiter): Variable, including an Auto mode for automatic corrective action
• Compressor Ratios: 1.5:1, 2:1, 3:1, 4:1, and 6:1 (Preset Ratios)
• Compressor Threshold Range: -20dBm to +10dBm

Conclusion

In summary, the AMS Neve 2264ALB brings together the vintage charm of the original 2264A with modern features, making it a versatile and essential tool for any audio engineer or producer.
