Ensemble Designs 6040 Tracking Audio Delay - Manual (Page 11)

Remote/Local switch:
Set to the mode you
will be using.
I/P ERR red LED:
With EXT REF switch set as follows:
External Mode:
ON for no signal at AES digital input.
OFF when valid AES signal present at
input at standard rate (48kHz, 44.1kHz
or 32kHz).
Auto Select Mode:
OFF when valid AES signal present at
digital input at 48kHz sample rate.
ON if no valid input signal present or
valid AES signal present at rate other
than 48kHz.
Pwr green LED:
Indicates the presence (ON)
or (OFF) of power (+5V).
CPU green LED:
OFF:
A power fault or halted CPU
ON:
A halted CPU
FAST BLINK:
CPU Run error
SLOW BLINK:
System OK. (If SPI control is
active from the main frame
System Control Module, all
Run indicators will be
synchronized.).
TRK ERR red LED:
ON when a Track (-1 - 3) has lost
communication with module it was
tracking. (Tracking delay value for
this module is set to 0.)
OFF when no tracking errors.
EXT REF green LED:
With EXT REF switch
set as follows:
External Mode:
ON for valid AES signal at external
reference input at 48KHz sample rate.
OFF when no signal or signal other
than 48kHz sample rate.
Auto Select Mode:
ON when module is locked to external
input (valid AES signal at 48kHz
sample rate).
OFF when not locked to external
reference input.
(Note that Auto Select checks AES
digital input first, then external input.)
Bulk Delay green LEDs:
Show bulk delay value.
(200 ms per LED.)
Front Panel Controls and Indicators
Each front edge indicator and switch setting is shown in the diagram below:
Model 6040 Tracking Audio Delay
6040-11
DELAY Adjustment:
Adjusts bulk delay
value in 10 mS steps
(4) IN SEL: Selects input source.
Left: Digital Input (default)
Right: Analog input
(3) BLK I/O: Bulk delay in or out.
Left: Bulk out (default)
Right: Bulk in.
(2) OUT I/O: Sets analog delay.
Left: Undelayed (default)
Right: Delayed
(1) EXT REF: Selects source of
external reference.
Left: Auto Select mode. Module will
scan in order, AES Digital Input,
External Ref Input or Internal clock
for PLL lock source.
Right: External Reference mode.
Module will lock to valid AES 48kHz
signal on external reference. If no
valid signal present, will default to
Internal clock.
