For decades, dbx’s patented Subharmonic Synthesis has rattled foundations enhancing the bass in a variety of professional applications including nightclub and DJ mixing, theatre and film sound, music recording, live music performance and broadcasting. dbx’s Subharmonic Synthesis process actually produces a new, Waveform Modeled bass note, exactly an octave below the bass in the original audio.

The dbx 510 answers the call of audio professionals everywhere delivering Subharmonic Synthesis in the convenient design of a 500 Series module. The 510’s two separate bands of subharmonic synthesis provide the best combination of smoothness and control, while the independent Low Frequency Boost circuit is designed to get the most out of high-performance, low frequency speaker systems. Unlike other attempts at bass synthesis, the dbx process produces musical low frequencies that don’t interfere with mid and high-band information, even when the maximum synthesis and boost are applied. The result is a low-end punch that people really feel!

Put some boom in your room with the dbx 510!

The dbx 520 will help you expertly tame the excessive sibilance often found in vocals and other high frequency dense material. Based upon the legendary dbx 902, the dbx 520’s unique features make it possible to achieve an exact amount of de-essing regardless of variations in signal levels. The 520 allows you to create brilliant, crisp vocals without sibilance!

With its modular 500 Series based design, the dbx 520 examines the differences in dB between the high frequency and full-bandwidth portions of a signal, allowing de-essing of signals which change in level by as much as 60dB. It features a Frequency Control with range from 800Hz to 8kHz, Gain Reduction Metering and a De-essing Amount Range from 0dB to 20dB.

Control vocals, drums, percussive instruments and problematic material/reverb combinations with the dbx 520!

The dbx 530 Parametric EQ offers a unique degree of equalization flexibility in the popular 500 Series format. Based upon the classic dbx 905, the dbx 530 is an uncompromising equalizer offering true, fully parametric operation of all three filter bands! dbx has a much-heralded history with modular processors dating back to our 900 Series, and the dbx 530 continues that tradition.

The dbx 530's overlapping bands each offer control of frequency bandwidth (Q) and up to 15dB of reciprocal cut or boost to provide exact, complimentary filter action for the most demanding of equalization needs. For problem situations requiring the removal of spurious signals, each of the bands can be independently switched into “infinite notch” mode without affecting the operation of others. In situations where a shelving equalizer will produce better results than a peaking one, the 530’s high and low bands can be independently switched from peaking to shelving operation. You can also make instant affected/bypassed comparisons using the 530's “On” switch.

The dbx 580 Microphone Preamp is the perfect partner to your microphones, providing sonically-transparent gain that will reveal the detail and audio signature of even the most esoteric microphones. It will transform their low level output signal to a high level, high current output for direct connection to the line level inputs of your mixer, sampler or any other recording medium that accepts line level, analog input.

With its modular 500 Series design, the dbx 580 delivers up to 60dB of gain, features a variable-frequency Low-Cut Filter and unique Low and High Detail Equalization Controls, a 20dB Pad, Polarity Invert, +48V Phantom Power, a Front Panel Instrument Input, VU Metering and Peak Indicator.

The dbx 560A Compressor/Limiter offers legendary VCA-based compression in the increasingly popular 500 Series format. dbx has a much-heralded history with modular processors dating back to our 900 Series and the 560A continues that tradition.

Featuring the same switch-selectable OverEasy® and Hard Knee compression curves as our industry-standard dbx 160A rackmount processor, the dbx 560A will be your new workhorse compressor! With extremely wide-ranging threshold, ratio and output controls and true RMS level detection providing the most natural-sounding dynamics processing available, the 560A will provide punch to drums, bass, vocals, almost anything! It’s also versatile enough to go from subtle compression to "brick wall" peak limiting.

Choose low ratios and OverEasy compression to expertly smooth out fluctuating vocal and instrumental levels, or use the 560A's Hard Knee compression and high ratios for bombproof protection against overload distortion in digital recording, P.A. systems and broadcast signals.

The 560A's 19-segment, switchable Input/Output LEDs and 12-segment Gain Reduction LEDs provide precise analysis at a glance. And, the dbx 560A's unique "INFINITY +" inverse-compression mode actually decreases the audio output level below unity gain when the input exceeds threshold, a real lifesaver for correcting overbearing vocal choruses and controlling runaway mix levels.
