3.2.2 Clock check
The status of all possible clock sources currently
connected to the TM-D4000 can be checked by mov-
ing the cursor to the
CHECK
box and pressing
ENTER . The console will mute, and a list of available
clock sources will be shown.
Press ENTER to continue operations.
3.2.3 Clock settings (other)
The
Fs STATUS
box shows the status of the
currently selected clock source.
The
WORD POLARITY
settings allow either
incoming or outgoing word clock information to be
inverted (
REVERSE
) relative to normal. This is
because some units either transmit or expect to
receive such signals in this inverted format.
3.2.4 Clock tolerance
When setting the clock, the sampling frequency
received can be ±6% of the stated nominal value.
When in use, the frequency can be ±7% of the stated
value. This allows a digital device which has a
varispeed feature to be used as the word clock source
for the TM-D4000.
If the selected clock source goes out of range, the
TM-D4000 will mute, the currently-selected clock
indicator will flash, and a message will appear on the
display:
The TM-D4000 will report the out-of-range clock
frequency at a range of ±9.9% relative to the stated
frequency, but will mute at 7.0% or over.
Press the ENTER key to dismiss the popup message,
change to the
CLOCK
screen, and correct the error
condition (by selecting another clock source, or by
re-selecting the clock if it has come back into range).
3.3 Option setup
In unshifted mode, this key is used to show the
OPTION
screens. There are three of these
screens:
SETUP
,
SOLO
and
SURROUND
,
and they are accessed by repeated presses of the
OPTION key.
The solo operations are explained in 4, “Module
operations”, and the surround operations in 6, “Sur-
round modes”.
The
SETUP
screen provides the following options
(as well as displaying the current battery voltage,
used to power the memory holding library entries,
etc.) as shown and described below:
These settings are generally made using the cursor
keys to move the cursor to the parameter to be
