Empirical Labs PUMP 500 Series Compressor with Opto-Style Auto Release, Attack Modification, and Saturation Mode - Vertica Faceplatel

PUMP is a high-performance compressor module from Empirical Labs with a legacy rooted in notable ELI processors like the Distressor, Arousor, and Mike-E. PUMP offers top-tier features for your professional ears. Boasting 8 selectable compression ratios, independent digitally-stepped knobs for precise Attack and Release control, and a switchable 110Hz High Pass Filter, PUMP offers uncompromising performance and value. Its innovative AtMod feature allows for fine-tuned adjustment of the attack envelope, preserving transient content for greater impact without sacrificing the desired level of compression or the source's character. Whether you need to enhance the snap of a snare track or add more thump to an electric bass, PUMP gives you the flexibility to shape your dynamics your way.

Empirical Labs PUMP Features:

• Input level control with clip indicator
• Selectable ratios from 2:1 to 20:1
• Independent digitally-stepped knobs for full control
• Soft Opt-style release
• Switchable 110Hz high pass filter
• Gain reduction metering
• Attack modification

Empirical Labs PUMP 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.
