Plate reverb B-7

Midas Digital Consoles

Addendum B

Plate reverb

The plate reverb effect simulates the actual plate reverb devices that were used in

studios in the 1960s and 1970s. They were literally a plate of metal that was

suspended under tension with a transudcer to transmit audio to the plate while two or

more contact microphones were attached to the plate to pick up the results. The plate

reverb has a very rapid build up of reflections and, as a result, is very dense initially

with a fairly smooth decay characteristic. For this reason it is typically the first reverb

choice for percussion instruments.

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

longer decay time at low frequencies, or alternatively can be useful to reduce low

frequency energy in a live environment where it may already be present due to the

natural reverberation of the venue.

Enabling the global tap option will change the pre-delay parameter units from

milliseconds to musical note durations as they do with the current effect units.

15 decay control

knob

Adjusts the decay time relative to the room size, from

minimum to maximum.

16 size control knob Specifies the room size (also affects decay), from

small to large.

17 pre delay control

knob

Specifies the time before the reverb begins, between

0ms and 200ms.

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 lf x-over control

knob

Adjusts the cross-over frequency for the low

frequency decay, in the range 20Hz to 500Hz.

5 in switch Switches the Plate Reverb effect in/out.

6 audition button This momentary-action button triggers a short

internally generated sound to aid reverb evaluation

(as a check).
