HARMAN subsidiary dbx is introducing its 500 Series processors — five half-rack-space recording studio signal processors. The new 500 Series models include the 560A Compressor/Limiter, 530 Parametric EQ, 580 Mic Pre, 520 De-Esser and 510 Sub Harmonic Synth.

The dbx 560A Compressor/Limiter provides control of dynamics including threshold, compression ratio and output gain. It offers selectable classic hard-knee compression or what they are calling “OverEasy” mode incorporating dbx’s highly musical program-dependent attack and release times. The compression ratio is variable from 1:1 through infinity:1 to -1:1. Adjustment is via the 560A’s ladder-style LED RMS gain-reduction and input/output meter displays with true RMS level detection.

Based on the design of the dbx 905, the dbx 530 Parametric EQ is a 3-band parametric equalizer with selectable bell or shelf-type filters on the low- and high-frequency bands, and adjustable Q on each band. The dbx 530 allows adjustment of level and bandwidth at frequencies that have been chosen by dbx.

The dbx 520 has a frequency control range from 800Hz to 8kHz and provides de-essing ranging from 0dB to 20dB. Its gain reduction metering provides at-a-glance indication of the amount of de-essing applied.

The dbx 510 Sub Harmonic Synth includes a low-frequency boost, subharmonic level and frequency range controls.

Pricing for the dbx 500 Series Lunch Box processors is 560A Compressor/Limiter, $399; 530 Parametric EQ, $399; 580 Mic Pre, $499; 520 De-Esser, $299; 510 Sub Harmonic Synth, $299. The 560A will be the first product in the series to ship available in April 2015. Here are all the specs.
