EmpiricalLabs 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.
