Hall reverb B-5
Midas Digital Consoles
Addendum B
Hall reverb
The hall reverb simulates the response of a real concert hall adding a sense of space to
the source material with less initial density than a chamber reverb. The slower build up
of reflections and generally longer decay times associated with this type of algorithm
allows for increased clarity of the source, while offering a richer more lush overall sound
that is less dense in character.
This effect features contour controls to adjust the envelope shape during the initial
portion of the reverb tail and also the time over which the reflection density increases.
Reflective surface materials and air absorption properties can be simulated by adjusting
the high and low frequency cut amount and high frequency damping. Low frequency
decay and cross-over parameters allow relative control over the low band reverb tail
length. This can be used to either simulate real room responses, which often have a
Item Element Function
1 input meter Two adjacent 11-LED columns — one each for left and
right — comprise the input meters.
2 mix control knob Adjusts the dry/wet signal ratio.
3 modulation
control knob
Specifies the combined rate and depth of modulation
applied the reverb tail.
4 contour time
control knob
Controls the time over which the reflection density
increases during the initial portion of the reverb tail.
5 lf x-over control
knob
Specifies the cross-over frequency for the low
frequency decay (lf decay), in the range 20Hz –
500Hz.
6 output meter Two adjacent 11-LED columns — one each for left and
right — comprise the output meters.
7 Audition button This momentary-action button triggers a short
internally generated sound to aid reverb evaluation
(as a check).
8 hf cut control
knob
High frequency cut control knob applies a 6dB/Oct
low pass filter to the input signal, in the range 200Hz
to 20kHz.
9 lf cut control knob Low frequency cut control knob applies a 6dB/Oct
high pass filter to the input signal, in the range 10Hz
to 500Hz.
10 hf damp control
knob
High frequency damping, progressively reduces the
high frequency content over time, in the range 1kHz
to 20kHz.
11 lf decay control
knob
Specifies the ratio of decay for low frequency content,
in the range 0.5 – 2.0.
12 diffusion control
knob
Increases the density of both the early reflections and
reverb tail, between 0 and 100%.
13 decay control
knob
Adjusts the decay time relative to the room size, from
minimum to maximum.
14 size control knob Specifies the room size (also affects decay), from
small to large.
15 pre delay control
knob
Specifies the time before the reverb begins, between
0ms and 200ms.
