DBX 560A Compressor/Limiter - 500 Series - DBX560A

Product Overview

The DBX 560A is a VCA-based compressor/limiter in the 500-series format that brings the same OverEasy and Hard Knee compression curves found in the industry-standard dbx 160A rackmount processor into a single-slot module. Designed for recording studio, broadcast, and live sound applications, the 560A provides true RMS level detection for the most natural-sounding dynamics processing available in the 500-series market, with a dynamic range exceeding 119 dB and THD+N below 0.005% at unity. Its unique Infinity+ negative-ratio compression mode extends its utility beyond standard compression into creative level control.

Product Description

The DBX 560A 500-series compressor/limiter delivers the legendary dbx VCA compression in a modular, single-slot format compatible with any standard 500-series power frame. The compression ratio is continuously variable from 1:1 through infinity:1 and beyond to -1:1, with the -1:1 Infinity+ mode decreasing the output level below unity gain when the input exceeds threshold. This feature addresses specific engineering challenges such as controlling overbearing vocal choruses and managing runaway mix levels in complex live and studio environments.

The 560A offers selectable OverEasy or Hard Knee compression curves, matching the behavior of the dbx 160A for engineers already familiar with that processor. Low ratios with OverEasy compression smooth out fluctuating vocal and instrumental levels with minimal audible artifacts, while high ratios with Hard Knee compression provide brick-wall protection against overload distortion in digital recording and broadcast signal chains. The 19-segment switchable input/output LED display and 12-segment gain reduction display provide precise metering for quick setup and monitoring.

Program-dependent attack and release times adapt automatically to the dynamics of the incoming signal, reducing the need for manual adjustment across diverse program material. The output level control provides +/-20 dB of make-up gain to restore the perceived loudness after gain reduction. At only 1.92 watts draw, the 560A is thermally efficient in fully loaded 500-series racks. Available at Creation Networks for recording, broadcast, and live sound applications.

Key Features

• OverEasy or Hard Knee Compression — Selectable curve matches the dbx 160A behavior for transparent program-dependent compression or precise peak control.
• Ratio 1:1 to Infinity:1 to -1:1 — Full range from gentle leveling through brick-wall limiting to the unique Infinity+ inverse-compression mode.
• True RMS Level Detection — Responds to the program's true RMS energy rather than peak values, producing the most natural-sounding dynamics control.
• Infinity+ Mode — Negative compression ratio actively decreases output level above threshold, providing creative and corrective level control beyond standard compression.
• 19-Segment I/O and 12-Segment GR Metering — Switchable input/output display and gain reduction display provide precise monitoring at a glance.
• +/-20 dB Output Level Control — Wide make-up gain range compensates for gain reduction at any ratio setting.
• Dynamic Range >119 dB — Preserves the full dynamic range of 24-bit digital audio systems.
• Program-Dependent Attack and Release — Automatic timing adapts to the dynamics of the signal for consistent results across diverse material.
• 500-Series Single-Slot Format — Fits any standard 500-series frame; draws only 1.92 watts.

Typical Applications

• Recording studio
• Broadcast studio
• House of worship
• Auditorium

Frequently Asked Questions

Q: How does the 560A relate to the dbx 160A rackmount compressor?

The 560A uses the same selectable OverEasy and Hard Knee compression curves as the dbx 160A, translating the sonic character of that processor into the 500-series format. Engineers familiar with the 160A will find the 560A behaves consistently.

Q: What is the Infinity+ compression mode on the 560A?

Infinity+ is a unique negative-ratio compression mode where the output level actually decreases below unity gain when the input exceeds the threshold. It is useful for taming overbearing vocal sections and controlling mix levels that exceed desired limits.

Q: Does the 560A have a side chain input?

The 560A does not include an external side chain insert. Frequency-sensitive detection requires an external compressor with a dedicated side chain path.

Q: What metering does the 560A provide?

The 560A provides a 19-segment LED display that is switchable between input and output monitoring, plus a 12-segment gain reduction LED display, giving the engineer complete visibility of signal levels and compression activity.

Q: Is the 560A compatible with all 500-series frames?

Yes. The 560A is compatible with any standard 500-series compatible power frame. It occupies one slot and draws 60 mA per +/-16V rail.
