CLONING DB2’S
Cloning DB2s
Cloning DB2’s using a PCMCIA card
Once a single DB2 has been set up for the
desired applications, other DB2’s in the house
can be easily cloned using a standard PCMCIA
card. In other words; it is NOT necessary to
hook up every single DB2 to a computer to set
these up.
• Insert an unprotected PCMCIA card into the
source DB2’s card slot.
• Go to the TC Icon System/Card page.
• Decide whether you wish to exclude the
System Preset that hold overall Clock
settings, Analog Trim levels, Dither, Status
Bit settings and GPI settings. To exclude the
System Preset, activate the “Exclude System
Preset” button.
Then click CREATE CLONE CARD.
ALL DATA previously stored on the card
will be destroyed when formatting the
card! If the card is write-protected, no
data can be written on the card. The
protect/unprotect switch is located at the
edge of the card.
• Remove the card and go to the target DB2
unit.
• Power off the target DB2 unit.
• Insert the card and power up using the front
panel POWER key while holding the OK key
pressed. Press UTILITY until the display
shows “C” (CLONE).
• Now press the OK key. All settings (with or
without “System Preset”, depending on your
previous selection) are now copied to the
target DB2.
SYSTEM – I/O PAGE
Parameters on the System page can be
stored and recalled via System presets and
are unaffected by normal Recall operations.
Clock Preferences
Analog
Range: Internal 44.1 kHz
Internal 48 kHz
Ext. W. Clk. (External Word Clock)
Ext. DI
Sets the processing clock frequency to be used
when analog inputs are used.
Digital
Range: Internal 44.1 kHz
Internal 48 kHz
Ext W Clk (External Word Clock)
Ext. DI
Sets processing clock frequency to be used
when processing signal from the AES or S/
PDIF input.
Digital w. SRC
Range: Internal 44.1 kHz
Internal 48 kHz
Ext Word Clock
Sets the processing clock frequency to be used
when Digital SRC is selected on the Engine I/O
page.
Analog Trim
Input Trim L & Input Trim R
Range: +1.00 to -1.00 dB in 0.05 dB increments
Level trim for analog inputs.
Output Trim L & Output Trim R
Range: +1.00 to -1.00 dB in 0.05 dB increments
Level trim for analog outputs.
Digital Output
Dither
Range: 8, 12, 14, 16, 18, 20, 22, 24, off
DB2 processes audio signals internally at 48 bit
resolution. Dither must be set to match down-
stream devices.
Status Bits
Select whether the DB2 should send out AES/
EBU or S/PDIF status bit information.
GPI
The GPI input reads the analog DC level fed
to this port, and may be assigned to a variety
of functions: It may set the output level, add
or change the on-line delay, enter and exit
bypass, and make DB2 switch between up to 8
presets.
GPI Assign
Disabled
The device connected to the GPI port is disre-
garded.
Fader
Select this setting to enable GPI control of
DB2’s output gain. The DC level on the tip of
the connector is read and used to adjust the
output gain (“Output Fader” on the Engine/
Limit page). Inside DB2, a 10 kOhm resistor
is connected b5 V and the tip of the
GPI jack. Therefore, a passive external fader or
potentiometer can be used to control the output
gain. Use the Calibration function to optimize
the control range for a given pot.
Bypass
Select this setting to enable bypassing DB2
using an external switch. Note that you may
accidentally put DB2 to bypass mode when
selecting between the GPI settings. The Bypass
function is defined on the System/Front page.
Bypass and Redundancy
DB2 includes hardware bypass on its analog as
well as AES3-id inputs and outputs.
When selected, the unit furthermore constantly
monitors its digital inputs for signal integrity.
If the digital input is lost, automatic input
redundancy switching is invoked. In this case,
DB2 switches to internal 48 kHz sample rate
operation and analog inputs.
Redundancy alarm is indicated by the 48 kHz
and Analog In LEDs blinking and the ERROR
LED lit. Once the digital input is reestablished,
DB2 reverts to normal operation and clears the
alarm.
