The E500-RS Selective Limiter by ADR Audio Design

The ADR E500-RS Selective Limiter is a high-end analog compressor/limiter designed for professional audio use, particularly in broadcast, post-production, and mastering environments.
Known for its smooth, transparent dynamics control, the E500-RS is highly regarded for its ability to control peaks and dynamics without adding distortion or pumping effects, making it a go-to choice for refining audio recordings.

Selective Limiting: The E500-RS is a selective limiter, meaning it can apply limiting to specific frequency bands. This allows for highly controlled dynamics manipulation, where you can limit specific sections of the frequency spectrum (e.g., bass, mids, or treble) while leaving others unaffected.
This is useful for shaping tone and preventing distortion in certain ranges while keeping others clear.
Threshold Control: Adjusts the level at which limiting or compression begins to engage.
This provides a high degree of flexibility when setting up the unit for different audio needs.
Attack and Release: Controls the attack and release times, letting you fine-tune how quickly the limiter responds to incoming signals and how quickly it returns to normal levels after reducing peaks.
Wide Frequency Response: The E500-RS offers an incredibly wide frequency range, which ensures it performs well across all audio applications, from dialogue and voiceovers to full-range music tracks.
Low Distortion: One of the standout features of the E500-RS is its ability to limit without introducing unwanted distortion, making it ideal for transparent limiting where audio integrity is key.
Dual-Band Limiting: It can offer dual-band limiting, which means it works in two frequency bands simultaneously, allowing you to apply more intense limiting to one frequency range (like low-end) while keeping others more natural.
The ADR Audio Design E500-RS Selective Limiter is revered for its precision and transparency, making it an excellent choice for professionals in mastering, post-production, and broadcasting environments where clarity and high-fidelity sound are paramount.

Usage and Applications:

• Broadcast: Ideal for radio and TV stations, providing precise control over signal dynamics in live broadcasting.
• Post-Production: Perfect for audio mastering or film post-production where selective limiting is necessary to control peaks in dialogue or music without affecting the overall mix.
• Mixing: Used in studio environments to control excessive peaks, especially when working with multi-track recordings or when mastering final mixes.
• Live Sound: While primarily designed for studio and broadcast applications, the E500-RS can also be used for live sound reinforcement when careful dynamics control is required.
