Cascade card
This card allows the connection of two DM-24 units
to increase the number of channels, etc. available. A
cascade card must be fitted in slot 1 of each unit to be
cascaded.
In a cascade chain, one unit is designated as the mas-
ter unit, and the other as a slave. The master unit
must always act as the word sync master for the cas-
cade chain (though it can act as a word sync slave in
the overall audio system).
There is one connection to be made between the two
units. This connection must be made between the
cascade cards with the power off on both units. It car-
ries all appropriate audio signals as well as the sync
signals and control signals.
Only use a TASCAM cascade cable designed and
produced for this purpose when making this connec-
tion.
This effectively gives you one double-sized DM-24
mixing console, with the following features:
• 32 mic/line inputs
• 64 channels
• 48 TDIF I/O channels
• 16 lightpipe I/O channels
• 4 AES/EBU 2-channel I/O
• 4 SPDIF 2-channel I/O
• 8 assignable sends and returns
• 4 internal effect processors
• 33 touch-sensitive, motorized faders
• The ability to run a 24-track, 24-bit 96 kHz 5.1
automated mixing environment
Setting up the cascade
When the connection between the two cascade cards
has been made, turn on the slave unit, followed by the
master unit. Wait until the fader calibration is ended,
and then go to the
SLOT screen (soft key 3 in the
DIGITAL screens) on the DM-24 which will be used as
the slave.
The cascade card is identified as CASCADE Card at the
top of the slot 1 section of the screen:
Set the unit up as the cascade slave ( SLAVE ) using the
on-screen radio button.
Now enter the same screen on the unit which will be
used as the master, and set that one up as the cascade
master (
MASTER button).
On the slave, set the CASCADE to ON . The display
shows Scan Cascade Machine . Leave the cursor by the
CASCADE button.
Next, on the master, set CASCADE to ON . Leave the
cursor by the CASCADE button.
The master display shows Found DM-24 slave machine!
and the slave display shows Found DM-24 master
machine! .
An error message is displayed if the cascade is estab-
lished and subsequently becomes disconnected.
Use of the cascade
Since the cascade function allows busses, aux sends,
etc. to be controlled from the master unit, and thereby
be shared between the two cascaded units, the two
DM-24s can be used as one large digital console. The ENABLE checkboxes allow the selection from the
master unit of which busses and functions will be
shared.
