							 TASCAM DM-24 Effects 3
1 – Internal Effects on the DM-24
The DM-24 contains a number of high-quality effects 
that you can use within your project, either while 
recording, or on mixdown.
The effects available include:
• Microphone modelling (single-channel)
 Speaker modelling (two channels)
 Chorus (two channels)
 Delay (two channels)
 Distortion (single-channel)
 Guitar compression (single-channel)
 Soft compression (two channel)
 Phaser (two channels)
 Pitch shifter (two channels) Flanger (two channels)
 De-esser (two channels)
 Exciter (two channels)
 Reverb (two channels)
Out of these, the two effects are available at any one 
time in 44.1 k or 48 k sampling frequency mode. In 
high sampling frequency modes (88.2k or 96 k), only 
one effect is available. 
NOTE
The following combinations cannot be used: reverb + 
reverb, reverb + speaker modeler.
In high sampling frequency mode, the reverb, micro-
phone modeler and speaker modeler are unavailable.
Patching and setting up effects
All effect settings are managed using the EFFECT 
key. This allows the assignment of sends and returns, 
as well as the selection and parameter setting for the 
effects.
There are two primary options, to use the effects 
independently in loop or insert mode, or to use the 
two effects in series, with the output of effect 1 feed-
ing the input of effect 2 (similar to some multi-effect 
units).
The first of these modes is known as the 
Loop/Insert 
mode, and the second as the 
EFFECT1 EFFECT2 Series 
mode.
Press the 
EFFECT key followed by soft key 1 
(
PATCH) to bring up the patch screen as shown here.
NOTE
When using the DM-24 in high sampling frequency 
mode, only one effect is available, and only one effect 
(
EFFECT 1) is shown on this screen.
Use the cursor keys to select the mode (either Loop/
Insert
 or EFFECT1 EFFECT2 Series), and the ENTER key 
to confirm the choice.
The lower part of the screen contains a representation 
of the two internal effect inputs and outputs. An 
effect may have two inputs (
L and R) and two outputs 
(
L and R). See “Mono and stereo inputs” on page 4 
for more information.
However, this does not mean that there are two sepa-
rate effect processors in each effect. It is possible to 
use the two inputs of the effect processor “creatively” 
(that is, have two completely separate feeds for the 
left and the right inputs of the effect), but this is not 
recommended. 
We strongly suggest that only pairs of inputs (e.g. 
stereo inserts, odd-even pair buss and aux inserts and 
odd/even pairs of aux sends) are selected as stereo 
inputs for the effects.
Use this screen to select the input sources for the 
internal effects.
The choices available are:
Use the cursor keys, dial and 
ENTER key to set the 
value for each input.

4 TASCAM DM-24 Effects
WARNING
Although it is theoretically possible to select both an 
aux send and an aux insert as input sources for an 
effect, a few seconds’ thought will show that this will 
result in a feedback loop, resulting in possible damage 
to equipment (and ears!). You should therefore avoid 
making this type of setting.
A popup message appears to show that the assign-
ment has been made.
NOTE
The same source cannot be selected twice to feed two 
different effect inputs (except for the aux sends). A 
popup message appears to warn of attempted dupli-
cate assignments.
Any send/return assignments made to the effects will 
override any assignments made to external send/return 
insert loops.
The effect output destination cannot be selected here—
the destination of the effect outputs is determined by 
the choice of the input source, and in the case of the 
aux sends by the settings made in the I/O screens.
Mono and stereo inputs
The DM-24 internal effects are either single-channel 
or two-channel, as listed at the start of this section.
At the top of the input/output patch section for each 
effect, there is a field called 
INTYPE (input type).
In the case of single-channel effects, the only option 
available is 
Mono.
In the case of dual-channel effects, there is a pair of 
radio buttons: 
Stereo and Mono. Select one of these as 
appropriate, depending on whether one mono source, 
or a stereo pair of sources (e.g. a pair of aux sends) 
will be used to feed the effect.
Once again, we recommend that only pairs of inputs 
(e.g. stereo inserts, odd-even pair buss and aux 
inserts and odd/even pairs of aux sends) are selected 
as stereo inputs for the effects.
The number of outputs available for an effect 
depends on a number of factors: the type of effect 
currently selected, the mono/stereo input type cur-
rently selected, and the destination of the effect (for 
instance, if effect 1 is patched in series with a sin-
gle-channel effect used in effect 2, only one channel 
is output from effect 1).
Example 1 (Loop/insert setting with 
1=mono input and 2=stereo input 
In this 
example, the delay line is fed by a mono signal 
source (for example a microphone) and the output is 
spread between the left and right outputs.
The stereo inputs to the plate reverb maintain the 
image of the stereo source (for example, if a pair of 
overhead mics has been set up to record a drum kit). 
						

							1 – Internal Effects on the DM-24—Effect send sources
 TASCAM DM-24 Effects 5
Example 2 (Loop/insert setting with 1 & 2 
both = stereo input) 
In this example, both 
effects are used in insert mode. Busses 1 and 2 use a 
effect 1 as a stereo phaser (this can be turned on or 
off as needed for a creative effect).
The stereo compressor assigned to effect 2 is inserted 
in the stereo output buss in order to limit the dynamic 
range of the stereo outputs.
Example 3: (Loop/insert setting with 1 & 
2 both = mono input) 
Here again, both effect 1 
and effect 2 are used as inserts, but they both have 
mono inputs.
Effect 1 (a distortion setting) is being used with a dis-
tortion effect, in order to achieve a distorted vocal 
sound.Effect 2 (a chorus) is inserted into an input channel 
(for example, a fretless bass) in order to thicken the 
sound. In this example, because these effects are 
being used by only one channel each, there is no need 
to tie up the aux sends and returns, which can then be 
used for other purposes.
Example 4: 1/2 series (1=mono input, 
2=stereo input) 
In this example, the two effects 
are put in series, with effect 1 (echo) taking a mono 
mic signal and echoing it to the left and right chan-
nels.
These echoes are then passed to the reverb, where 
they are processed “in-place” to provide an interest-
ing stereo effect (note that reversing these two effects 
would produce echoed reverb—probably less desir-
able).
Effect send sources
Whether the effect (or in series mode, both effects 
together) is used as a loop or an insert depends on the 
source selected for the effect inputs.
Aux 1 through 6 When these are selected as 
effect input sources, the effect is placed in a loop. The effect output with this setting is assigned to a 
channel using the I/O screens (see “Signal sources” 
on page 36 of the main manual).
If a channel has already been assigned to take its 
input from an internal effect, this channel is shown  
						

							1 – Internal Effects on the DM-24—Effect send sources
6 TASCAM DM-24 Effects
on the OUT section of the screen when the loop 
assignment is made and is shown as 
Chxx (xx = 1 
through 32). If no channel has been assigned, the dis-
play shows 
---. If more than one channel has been 
assigned as a return, the display shows 
****.
Aux 1 through Aux 6 insert When these are 
selected as effect input sources (
AUXx INS SEND), the 
effect becomes an insert-type effect. 
This insert is made post aux send fader.
The outputs of the effect are automatically assigned 
to the appropriate aux insert returns and shown as 
AUX INS RETURN.
Buss 1 through buss 8 insert When these are 
selected as effect input sources (
BUSSx INS SEND), the 
effect becomes an insert-type effect. 
This insert is made post buss level fader.
The outputs of the effect are automatically assigned 
to the appropriate buss insert returns and shown as 
BUSS INS RETURN.
Stereo L, R insert When these are selected as 
effect input sources (
ST-L PRE SEND and ST-R PRE 
SEND
), the effect becomes an insert-type effect.This insert is made pre stereo master fader.
The outputs are automatically assigned to the stereo 
insert returns are shown as 
ST-L PRE RETURN and ST-R 
PRE RETURN
.
Assignable inserts 1 through 4 When these 
are selected as effect input sources (
ASGN INSx SEND), 
the effect becomes an insert-type effect.
For these to be effective, the assignable send/returns 
must be set to be inserts, not send/return loops (see 
“Assignable sends and returns” on page 43 of the 
main manual). If they have been set to send/return 
loops, a popup message appears informing you of the 
fact.
Note that when an assignment is made to these 
inserts, the corresponding physical 1/4” jacks are no 
longer available (these settings override the physical 
jack insert assignments).
The outputs from the effects are sent to the assign-
able insert return. This is shown in the output assign-
ment section of the effect as 
ASGN INSx RTN CH y if a 
channel assignment has been made, or 
ASGN INSx RTN 
--- 
if no assignment has been made.
Effect 1-2 series
When the two effects units are selected to act in 
series, with effect 1 feeding effect 2, although both 
effect 1 and effect 2 are shown on the screen, only the 
inputs to effect 1 may be set.
The output(s) from effect 1 are automatically routed 
to the input(s) of effect 2.
If the source of effect 1 is an aux send, the effect 2 
output is assigned to a channel (set using the I/O 
screen). If the source of effect 1 is an insert, the output of 
effect 2 defaults to the insert return as shown in the 
output assignment section of effect 2. 
The outputs from effect 1 are shown as 
EFFECT2 IN L 
and 
EFFECT2 IN R, and the inputs to effect 2 are shown 
as 
EFFECT1 OUT L and EFFECT1 OUT R (if effect 2 is a 
dual-channel effect). 
If channel 2 is set to output only a single channel, the 
single output from effect 1 is labeled as 
EFFECT2 IN L 
and if there is a single input to effect 2, this is labeled 
EFFECT1 OUT L. 
						

							1 – Internal Effects on the DM-24—Setting up the effects units
 TASCAM DM-24 Effects 7
Setting up the effects units
To use one of the internal effect units, press the 
EFFECT key and then soft key 2 or soft key 3 (EFFECT 
1
 or EFFECT 2).
Next, use the 
EFF... LIB-> key (soft key 4) to enter the 
effects library.
Use the cursor keys and 
ENTER key to select either 
one of the two effect preset banks or the user effect 
bank.
There are two preset library banks: 
 The first bank holds the TC Works reverb preset 
settings, as well as blank templates for the Antares 
microphone and speaker modelers (“Preset reverb 
settings” on page 22).  The second holds preset TASCAM effect settings 
(“Preset effect settings” on page 27).
Use the library screen to scroll through the list of dif-
ferent library entries in the selected bank.
See “Library functions” on page 99 of the main man-
ual for full details regarding library functions.
NOTE
Although the preset library banks are named 1 and 2, 
an effect from library bank 1 may be recalled for use 
with effect 2, etc., as well as the other way round. 
Remember, though, that when using effects in series, 
effect 1 always feeds effect 2. If the effect settings are 
recalled to the wrong effect, the sound may not be 
quite what you expect (echoed reverb is rather differ-
ent from reverbed echo, for example).
When you recall a library entry from the library, a 
popup message appears confirming the selection.
When the 
EFFECT key is pressed, the effect screen 
showing the values and parameters appropriate for 
that particular type of effect is displayed.
Once an entry has been recalled, there is no way of 
changing its type through the on-screen parameters. 
You must reload an entry of another type from the 
library in order to change the effect type.
NOTE
The points at which the effects are returned are set in 
the I/O screens and are selectable in the same way as for 
mic/line inputs, etc.
Changing parameters
The parameters of the entry are changed using the 
cursor keys and PODs, dial and 
ENTER key, in the 
same way as other parameters on the DM-24.
These parameter settings take place immediately 
(that is, the effect of the change can be heard imme-
diately after the parameter has been changed).
See the appropriate sections of this manual for details 
of how the parameters change depending on the 
effect type selected.
Essentially, there are two different types of effect: the 
in-line type of processor, typically used in an insert 
mode, and the send/return type, typically used in a 
loop mode (aux send to channel return).There are no hard and fast rules as to how these 
should be used, though. If you wish to use the guitar 
amplifier simulator to add an unusual sound to a 
string quartet, you are of course free to do so!
Note how all effect screens have a pair of input 
meters and a pair of output meters at the top left of 
the screen so that the level can be properly adjusted.
The microphone modeler has (in the top row of 
PODs) an input and an output level control.
The speaker modeler has (in the top row of PODs) an 
input control.
The reverb and the other (TASCAM) effects all have 
(in the top row of PODs) an input and output level 
control, as well as a mix (wet/dry) control. 
						

							1 – Internal Effects on the DM-24—Changing parameters
8 TASCAM DM-24 Effects
NOTE
On account of unavoidable processing delays, it is rec-
ommended that the mix control be always set to 100% (fully wet), as the original and processed sound may be 
a few samples out of phase with each other, resulting in 
audio artifacts if the two signals are mixed.
Storing your settings
When you have set up the parameters of an effect, 
you can store it for further use in the user effects 
library.
This saves you having to make the same settings 
every time for a commonly-used microphone model, 
for example.
While in the effect parameters screen, press soft key 
4 (the 
EFF...LIB key) to bring up the library screen. 
This allows you to scroll through the list of settings 
and either save to an unused library entry in the user effect bank, or to overwrite an existing setting stored 
in the library.
Again, consult the main manual for details of how to 
name and manage library entries.

2 – Notes on using effects
Because of the nature of the DM-24’s routing, a little 
thought may be needed when assignments are made 
on the effect patch page, as the DM-24 allows the 
same signal to be routed to more than one channel 
simultaneously.
Although this kind of versatility is often desirable, it 
is important to make sure that this kind of assignment does not happen accidentally, causing unexpected 
and unwanted results.
This section provides some tips and pointers on how 
to best set up the DM-24 in order to avoid any such 
possible problems.
Default snapshot settings
The default mix snapshot returns the outputs from 
effect 1 and effect 2 to channels 25/26 and 27/28 
respectively.
In the same snapshot, assignable returns are assigned 
to channels 29 through 32.These settings are designed for the use of the internal 
sends with the aux sends and returns, and external 
effects with the hardware insert loops (assignable 
sends and returns). If you are making changes to use 
the internal effects or assignable sends and returns as 
inserts or assignable inserts, a little work must be 
done, using the assignment screens.
Using the internal effects as inserts (i)
In this example, effect 1 will be used as an insert on 
buss 2.
To do this, the effects returns must first be removed 
(de-assigned) from channels 25 and 26.
With the 
SHIFT indicator lit, press the I/O key until 
the screen allowing assignment of channels 17 
through 32 appears (or use soft key 2 to access the 
screen).
You should set these inputs to some “harmless” set-
ting which will not conflict with any other setting 
that is already in use. A useful source here might be 
one of the digital inputs (if you are not already using 
them).
NOTE
It is possible to assign the same source to more than one 
channel. There are obvious dangers associated with 
such an action, so we do not recommend that you do 
this.
Next, return to the effect patch page (press the 
EFFECT key until the patch screen appears):
Select 
BUSS2 INS SEND as the input source for effect 
1. When you do this, the output for effect 1 will auto-
matically change (
BUSS INS RETURN).
If you had not removed the effect returns from chan-
nels 25 and 26 before assigning the buss insert send, the 
effect return would have been routed to these channels 
as well as to the buss insert return (as in the screen shot 
above). 
						

							2 – Notes on using effects—Using the internal effects as inserts (ii)
10 TASCAM DM-24 Effects
Using the internal effects as inserts (ii)
In this section, we look at how you change the 
default settings to use effect 2 as a stereo input pro-
cessor using assignable send/return inserts 1 and 2. 
The insert will be assigned with channels 1 and 2.
Again, use the 
I/O key (the SHIFT indicator must be 
lit) to access the 17 through 32 screen (soft key 2), 
allowing the de-assignment of the assignable returns 
1 and 2 from channels 29 and 30.
Again, pick a “safe” or harmless option of an input 
that you are not using.
Next, the assignable sends and returns have to be 
changed from their send/return loop setting to an 
insert setting.
Press soft key 4 to access the assignable output 
screen:Assignable send/returns 1 and 2 should be set to the 
insert mode.
The insert channels (that is, the channels on which 
the inserts will work) should be set to channels 1 and 
2 (of course, you are free to change this if you want 
to use other channels with this effect.
In the 
EFFECT patch page, select Stereo as the input 
type for effect 2.
Change the input source to 
ASGN INS 1 SEND (CH 1) 
for the left input and 
ASGN INS 2 SEND (CH 2) for the 
right input.
NOTE
It is important that these operations are carried out in 
the order here.
If you try to route these assignable inserts to effect 2 
(on the effect patch screen) without changing the 
assignable send/return mode first, a popup message 
appears telling you that the assignable insert is in the 
send/return mode. 
If you then try to correct this by changing the send/
return mode to the insert mode, another message 
appears, informing you that return 1 is currently 
assigned to channel 29.
