8 - Dynamics processors-Compressors Compressors The 32 channel compressors and the six assignable output compressors all have the following parameters which may be set. The controls here refer to the controls on the DYNAMICS screen: Threshold (THRESH), controlled by the POD 1 knob, and variable from -48dB to 0dB in 1dB steps. Compression ratio (RATIO), controlled by the POD 2 knob, and variable from 1:1 to ∞:1 (infinite compression). The steps are as follows: 1.00:1, 1.05:1, 1.11:1, 1.18:1, 1.25:1, 1.33:1, 1.43:1, 1.54:1, 1.67:1, 1.82:1, 2.00:1, 2.22:1, 2.50:1, 2.86:1, 3.33:1, 4.00:1, 5.00:1, 6.67:1, 10.0:1, 20.0:1, ∞:1. Attack time (ATTACK), controlled by the POD 3 knob, and variable from 0ms to 125ms in 1ms steps. Release time (RELEASE), controlled by the POD 4 knob, and variable from 5ms to 5.0s in 100 steps. From 5ms to 200ms, the steps are 5ms apart; from 200ms to 300ms, the steps are 10ms apart; from 300ms to 500ms, the steps are 20ms apart; from 500ms to 1.00s, the steps are 50ms apart; from 1.00s to 3.00s, the steps are 0.1s apart; and from 3.00s to 5.00s the steps are 0.2s apart. Auto make-up (AUTOmk-up), controlled by POD 3 used as a switch. This is used if the compression settings have resulted in gain reduction. Output gain (OUTGAIN), controlled by the POD 4 knob on the last row (grayed out if the auto make-up above is on). Variable from -20dB to +20dB in 1 dB steps. Preset library entries The following preset entries are provided either to be used "as-is", or to be used as templates or starting points for experimentation. These library entries are read-only (marked with an inverse R on the display), and may not be overwritten. However, it is possible to load the entries, edit the parameters, and then store them to a different library entry. As always, there are no hard and fast rules as to what "works". Feel free to use the settings in a variety of contexts and change them as seems appropriate to you.

TASCAM DM-24 Reference Manual

Compressors

The 32 channel compressors and the six assignable

output compressors all have the following parameters

which may be set. The controls here refer to the con-

trols on the

DYNAMICS

screen:

Threshold

(

THRESH

), controlled by the POD 1

knob, and variable from

-48dB

0dB

in 1dB steps.

Compression ratio

(

RATIO

), controlled by the

POD 2 knob, and variable from

1:1

∞

(infinite

compression).

The steps are as follows:

1.00:1

1.05:1

1.11:1

1.18:1

1.25:1

1.33:1

1.43:1

1.54:1

1.67:1

1.82:1

2.00:1

2.22:1

2.50:1

2.86:1

3.33:1

4.00:1

5.00:1

6.67:1

10.0:1

20.0:1

∞

Attack time

(

ATTACK

), controlled by the POD 3

knob, and variable from

0ms

125ms

in 1ms steps.

Release time

(

RELEASE

), controlled by the POD 4

knob, and variable from

5ms

5.0s

in 100 steps.

From 5ms to 200ms, the steps are 5ms apart; from

200ms to 300ms, the steps are 10ms apart; from

300ms to 500ms, the steps are 20ms apart; from

500ms to 1.00s, the steps are 50ms apart; from 1.00s

to 3.00s, the steps are 0.1s apart; and from 3.00s to

5.00s the steps are 0.2s apart.

Auto make-up

(

AUTOmk-up

), controlled by POD

3 used as a switch. This is used if the compression

settings have resulted in gain reduction.

Output gain

(

OUTGAIN

), controlled by the POD 4

knob on the last row (grayed out if the auto make-up

above is on). Variable from

-20dB

+20dB

in 1 dB

steps.

Preset library entries

The following preset entries are provided either to be

used “as-is”, or to be used as templates or starting

points for experimentation.

These library entries are read-only (marked with an

inverse

on the display), and may not be overwrit-

ten. However, it is possible to load the entries, edit

the parameters, and then store them to a different

library entry.

As always, there are no hard and fast rules as to what

“works”. Feel free to use the settings in a variety of

contexts and change them as seems appropriate to

you.
