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 44.1kHz
Internal 48kHz
Ext. W. Clk. (External Word Clock)
Ext. DI
Sets the processing clock frequency when
analog Inputs are used.
Digital
Range: Internal 44.1kHz
Internal 48kHz
Ext W Clk (External Word Clock)
Ext. DI
Sets processing clock frequency when
processing signal on the AES or S/PDIF Inputs.
Digital w. SRC
Range: Internal 44.1kHz
Internal 48kHz
Ext Word Clock
Sets the processing clock frequency when
Digital SRC is selected on the Engine I/O page.
Analog Trim
Input Trim L & Input Trim R
Range: 0.05 to 41dB
Level trim for Analog Inputs
Output Trim L & Output Trim R
Range: 0.05 to 41dB
Level trims for Analog Outputs.
Digital Output
Dither
Range: 8, 12, 14, 16, 18, 20, 22, 24, off
P2 processes internally at 48 bit resolution.
Dither must be set to match downstream
devices.
Status Bits
Select whether the P2 should send out
AES/EBU or S/PDIF status bit information.
GPI
Via an external Fader or alternating (latching)
switch various functions can be controlled.
GPI Assign
Disabled
Connected device to GPI is disregarded.
Fader
Connect e.g. a TC Master Fader (not included)
to control the Master Out level parameter.
(see calibrate section next page).
Bypass
Connect an alternating (latching) switch to
remote control Bypass function. Note that the
Bypass function is defined on the System Front
page. (see calibrate section next page).
Preset
Range: 2 presets, 4 presets or 8 presets
Selection between up to 8 presets (equivalent
to the Front Panel recall keys) is achieved by
feeding the processor a DC voltage to its 1/4"
jack input. The Input voltage is compared
against voltage windows that correspond to
certain presets.
Between the valid voltage windows, invalid
windows have been inserted to protect against
erratic operation. The processor constantly
monitors the GPI Input, and only if several
consecutive measurements point to the same,
valid voltage window, a recall is performed.
The voltage windows chosen enable easy
"binary relay encoding" as shown on the next
page in fig. 1. If long cable runs are required,
HF decoupling using a ceramic capacitor
across the Tip and Sleeve terminals inside the
jack plug may be indicated.
The ring terminal of the 1/4" jack is not
used.
