PUMP is a single channel, 500 series rack mount compressor loaded with the kinds of features and performance you’ve come to expect from Empirical Labs.

PUMP features an Input Level control with a clip indicator labeled "BAD." It offers 8 selectable compression ratios ranging from 2:1 to 20:1, each with its own distinct curve. The unit provides precise recall with digitally-stepped knobs for independent control over Attack and Release, including a soft, Opto-Coupler-style Release. PUMP also includes a switchable 110Hz High Pass Filter, detailed Gain Reduction metering, and Attack Modification (AtMod) to slow the attack onset, preserving transients for more impact, plus a Bypass option for a dry signal.

Specifications
Frequency Response – 5 Hz to 175 kHz (-3dB points).
Dynamic Range – 125 dB from maximum output (.5%THD soft clipping) to minimum output. Noise floor with Output on 0 is typically – 101dBu.
Distortion – between .0035% and 15% at 1KHz, depending on mode and settings.
I/O – Maximum Input before hard clipping – +22dBm, “ Line In” mode. Maximum Output (Mix at 0) – +28.5dBm
Impedance – 120k Ohm, Instrument In Mode, output impedance is less than 75 ohms. 20K input impedance in balanced Line in mode.
Compressor Time Constants – Attack: 200µs to 40ms. Release: 50ms to 500ms, plus Opto setting. Stereo Linkable for stereo tracks.
Detector HP Filter – Switchable, fixed at 110Hz
Attack Modification (AtMod) – Slows the initial onset of the attack envelope allowing more transient back into the track.
Saturation Soft Clipper – based on the same circuit found in the Mike-E CompSat section.
