Theta Digital Casablanca II, Owner'S Manual

The first four 3.5 mm jacks on the rear panel (remote power and main power 1 through 3) are +12V pulse or DC
current limiting* outputs (tip = hot, sleeve = ground) and are intended to be connected to devices which feature 12V
control voltage inputs.
Toggling the hand held remote or front panel REMOTE button will activate/deactivate the REMOTE power jack output.
It will turn off when the Casablanca II is put into standby mode.
Use button # 1 to indicate whether the output of the remote power jack should be 12VDC ( DC ) or a 12V pulse
( PULSE ). The specification sheet for the device connected to the remote power jack should contain information as to
which type of signal it requires, and if it is a pulse, the minimum pulse duration.
The output signal of the remote power jack does not need to be delayed since it’s activation is by the user via either the
hand held remote or front panel
REMOTE button.
Buttons 2 , 3 and 4 have exactly the same functionality as button 1 , except that they apply for the three MAIN POWER
jacks on the rear panel.
The MAIN POWER 1 jack is activated immediately upon exiting the standby mode (pressing the front panel or the hand
held remote POWER button), the MAIN POWER 2 jack is activated X seconds after exiting standby and the MAIN
POWER 3 jack is activated X times 2 seconds after exiting standby. X represents the time, in seconds, that is set by
pressing button # 5 – MTIM , or Main [Delay] Time. This is useful for sequencing the turn on of high power components
such as amplifiers. Further to this, when the Casablanca II is put into standby, it can be set that all of the MAIN
POWER jacks turn off simultaneously or sequenced off in the opposite order as they were activated. This is
accomplished by setting SEQ (button # 6 ) to ON or OFF . By setting the SEQ parameter to ON , the user is activating
the power down sequencer.
If the type of output for any of the rear panel power jacks is set to PULSE , the duration (in milliseconds) of this pulse
can be set by the user, using the A-D button.
*Current limiting resistor is 33
:
0. 5W. This means that the more current a device to be triggered draws, the more the
output voltage gets reduced. The formula is : Output voltage =12 – (I x 33), where I = the current draw from the
triggered device, in Amperes. Refer to the device’s manual for this information. The Casablanca II’s maximum output
current is 100mA, which, by using the above formula, means that with a 100mA draw, the output voltage will be 8.7
volts, although most triggered circuits have virtually no current draw.
Clear Balance (Temporary Settings Control)
Any changes in the BALANCE menus are, by default, temporary. That is to say that when an INPUT SELECT button
is pressed or the Casablanca II is powered down/put into standby, any changes will be reset to zero. This feature has
an override, which is set by pressing button #
4 in the first SETUP / GLOBAL page (figure 51 on page 66) and set to
OFF . When this parameter is set to OFF , changing inputs or powering down/going into standby will maintain all
BALANCE menu settings.
RS232
In the first SETUP / GLOBAL page, press button # 5 to access the RS232 sub menu shown in figure 55.

Press button #
1 ( BAUD ) and use the LEVEL UP / DOWN buttons to select the Baud rate that matches that of the
RS232 controller.
The Casablanca II can be set to automatically send changes to the RS232 port. This can be done by selecting a
“Status Level”, which means if any Casablanca II parameter changes, that level's bytes will be sent to the port. This is
useful for monitoring master level, input and the like when the user has access to both the Casablanca II and the touch-
panel controller, to keep them synchronized.
Button # 2 ( ECHOS ) [Echo Status] allows the user to enable or disable the output of data to the RS232 port and, if
enabled, determine which level, or pre-determined group of bytes it outputs. Setting this value to OFF disables any
parameter change information from being output to the RS232 port. If RS232 is installed in a Casablanca II, an
