Description
The Empirical Labs Pump Duo 500 Series, comprising a pair of Empirical Labs PUMP Classic Knee Compressor Modules mounted horizontally in a single-rackspace Wave Distro Powergrid Duo enclosure.
Empirical Labs Pump Duo 500 Series Included:
- 2 x Pump Serie 500 Compressor
- Rack Wave Distro Powergrid
- Recessed slots that enable two 500 Series modules to be flush mounted for a clean look
- XLR inputs and outputs
Empirical Labs Pump Information:
PUMP includes controls for Input Level with a clip (BAD) indicator. There are 8 selectable compression ratios from 2:1 to 20:1 and everything in between, each with their own unique curve. Independent digitally-stepped knobs provide precise recall of Attack and Release selections – including a soft Opto-Coupler style Release. PUMP has a switchable 70Hz High Pass Filter, comprehensive Gain Reduction metering, Attack Modification (AtMod) to slow the initial onset of the attack envelope to preserve more transient content for greater overall impact – with a Bypass selection to go dry. AtMod gives users the ability to slow down the initial slope of the attack envelope to add just a little bit more of the transient back into the track. Whether it’s to get a little bit more snap on the snare track or more thump on the electric bass, the AtMod will let the transients through without losing your desired amount of compression.
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 70Hz
- 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.
