11 - Cascade—Cascade connections
11–2
The master unit will check the connections,
and check for the presence of other units in
the cascade which have had their IDs set
correctly. The screen below will be shown if
two correctly-congur ed and connectred
slaves are discovered in the cascade.

Press
ENTER
to continue with the cascade
operations, or, if the number of slaves has
been wrongly reported, press a cursor key to
cancel, check connections and settings, and
re-try.
If no slaves are discovered by the master, the
following screen appears:

When
ENTER
is pressed (in 6 above), the
slave units’
CLOCK
indicators will go out, as
the slaves lock their clocks to that of the mas-
ter unit.
After the clocks have been set, other internal
settings are communicated between the mas-
ter and slave units. Do not try to add or
remove units from the cascade. The following
message appears if a cascade connection is
broken or a unit is removed (via software)
from a cascade while this negotiation is tak-
ing place:
When turning on a previously-congured cascade of
units, make sure that the master unit is always turned
on
last
.
It is not possible to turn the cascade function off on
any unit or to turn the power off on a cascaded unit
while the cascade is in use. If the power to a slave
unit is turned off accidentally, turn the slave off
again, and restart from step 5 (turning the master
unit’s cascade off and on again to re-recognize the
existence of the slaves).
The top on-screen button in the
DIGITAL I/
O CASCADE
screen, shown below, is used to
turn the cascade on or off. If this is set to
OFF
, the
unit is described as being out of the cascade, even if
it is physically connected as part of the chain.
NOTE
Do not attempt to turn the cascade on or off
while the initial “negotiation process” is taking
place, as described above. If an attempt is
made to do this, the cascade setup must be
re-started from the beginning. If the cascade
function of a slave unit is turned off while the
cascade is in operation, the cascade setup
process must be re-started from step 5
above.
Every time the units in a cascade are powered off,
their cascade status and IDs are memorized. How-
ever, so that the master can negotiate the cascade sta-
tus, it is important that the slave units are turned on
rst, allo wing the master to recognize the slave units
when the power is turned on. The cascade slaves
should be recognized, and
ENTER
pressed to con-
tinue using the cascade.
11.1.1Selecting busses for cascade
In the
CASCADE
screen of a slave unit, it is pos-
sible to select the following for cascade through the
chain, or to make them local to the unit:
• output busses 1 through 8
• Aux sends 1 through 4
As explained above, Aux sends 5 and 6 may be used
with the individual effect processor of each unit, pro-
viding greater e xibility in effect processing in a
larger system.
When a buss or Aux send has a check mark beside it
(
✔
), the buss or send is passed through from the unit
to the master unit. In addition, the summed eight out-
put busses are output in parallel from all slave units
that add their buss to the cascaded summed buss, as
well as the master unit.
