TASCAM DS-M7.1
Inserts
Either analog or digital insert units can be connected
to operate after the
BUS/RTN switch. These are
selectable pre- or post- the Input Summing Router.
These inserts can be pre- or post- the input summing
router (placed between the inputs and the RTN/BUS
selector switch) and always pre- the RTN/BUS
switch. See the block diagram at the end of this man-
ual for details.
Either AES/EBU digital devices, or analog (standard
+4dBu balanced) may be used here. Note that when
making connections to an analog insert unit, because
of the nature of the connectors used, two connections
need to be made, one for input and one for output.
After the connection has been made, you should set
up the insert as follows:
1 Press the INSERT key so that the screen
shows something like:
2 There are three parameters. Use the cursor
keys to select them. First, select whether the
insert loop is enabled (
ENABLED ) or dis-
abled ( DISABLED ).
3 Next, select the position of the insert loop, as
described above: either
PRE SUM or
POST SUM (i.e. before or after the input
summing router).
4 Finally, set the Return type: ANALOG
(analog) or DIGITAL (digital).
Monitor connections
There are two sets of monitor connections, analog
and digital.
The analog connections are standard balanced
+4dBu connections, and the digital outputs are in
AES/EBU format.
NOTE
The sampling frequency output from the digital moni-
tor outputs is the input frequency. If you are mixing a
high sampling frequency project, you must therefore
make sure that your digital monitoring setup can han-
dle these frequencies, or use the DS-M7.1’s analog mon-
itoring ports.
The analog and digital signals are output in parallel,
and there is no switching between them.
TIP
The AES/EBU monitoring signals can be used in parallel
with the analog monitoring signals to drive a suitably-
equipped meter bridge.
However, there is one setting that can be made for the
AES/EBU digital ports; the “pick-off” point for the
monitoring.
This can be set so that all the downmix, bass manage-
ment and delay settings, together with all muting and
soloing and level settings described in “Other moni-
toring settings” on page 17, are ignored, or so that
these settings take effect through the digital port.
This affects the digital outputs only—the analog out-
puts will always reflect these settings.
7 Frequency error The master clock is not a recognized frequency (e.g. 32 kHz). Check the master set-
tings and correct, if necessary.
8 AES/EBU preamble error (normal) At normal sampling frequencies, the preamble of the AES/EBU signal acting as the
clock source cannot be read by the DS-M7.1. Check and correct settings on the clock
master.
9 AES/EBU preamble error (high-speed) At high sampling frequencies (88.2 kHz and 96 kHz), the preamble of the AES/EBU
signal acting as the clock source cannot be read by the DS-M7.1. Check and correct
settings on the clock master.
