Dear producer, engineer, musician. Thank you for using SounDevice Digital Verbum Entropic Hall. We hope it will help to improve your music and sound the way you wish. Or maybe even better.


Verbum Entropic Hall is a vintage style digital reverb with unique character and colour. To explore its power, please, simply start by by running through the presets. After you do so, you may wish to tweak the reverb‘s parameters. This guide will help you… 

Verbum Entropic Hall Controls

The main controls are self-explanatory.


Mode: Choose one of the three reverb algorithms Verbum offers.

Predelay: sets pre-delay of Verbum. 

Decay: Controls the decay time of the reverb.

Dry/Wet: Sets the relation of dry and effected signals. 

HP: HiPass - Cuts off wet signal low frequencies (0–500Hz)

LP: LowPass - Cuts off wet signal high frequencies (0,5–16kHz) 

12 BIT: This button turns on the simulation of Vintage ADDA Converters causing interesting distortion effect.

Power ON/OFF: Bypasses the effect.


These are advanced controls of the reverb. 

Width:  This knob sets stereo width of reverb. 0 is default, 200 is maximum widening.

Colour: Controls analogue saturation circuit simulation.

Legendarism: Special process of simulation colour and saturation of legendary reverbs.

ER/LR: Sets the ratio between Early and Late Reflections


This section is dedicated to controlling the Late Reflections only.

Size: Size of late refections

Predelay: Predelay of late reflections

Damp: Dampening turns high frequencies of reverb down faster. (If you have a reverb length of 5 seconds dampening will make the low frequencies be 5 seconds long, mid frequencies are 3 seconds long, high frequencies are 1 second long.)

Lush: Special LR modulation softening the reverb sound.


Level: Level of modulation

Frequency: Frequency of modulation


Ducking Amount - controls the level of suppression of the wet signal when the new dry signal comes in. 

Time - controls how fast the wet signal goes back to the original level.
