Type 1 bass management
When type 1 bass management is selected, the screen
looks something like this:
FRQ The frequency at which the crossover occurs:
80, 100 or 120 (Hz).
MCH>LFE The amount of main channel signal (L,
C, R, LS, RS) added to the LFE monitor channel.
This is set together with the LFE>LFE parameter as
described below.
LFE>LFE The amount of LFE signal added to the
LFE monitor channel. This is set together with the
MCH>LFE parameter described above.
Two sets of values are available for these linked
parameters:
Type 2 bass management
When type 2 bass management is selected, the screen
looks something like this: Apart from the type, there are only two parameters
on this screen that can be changed:
SUB Turns the sub channel on and off.
FRQ The frequency at which the crossover occurs:
80, 100 or 120 (Hz).
All other settings are fixed and are provided for
information only.
High speed operation
Remember that although the DS-M7.1 is capable of
high-speed operation (88.2 kHz and 96kHz sampling
frequencies) as determined by the frequency of the
word clock source (see “A note on the word clock”
on page 14), as mentioned earlier, this is not an
option supported by the TASCAM DM-24 digital
mixing console, and it may not be supported by other
units.
Even if a high clock rate is selected in the SYSTEM
setup screen, the incoming clock at the BNC WORD
IN can be either the base rate (48k for 96k, or 44.1k
for 88.2k) of the selected high-speed rate or the
actual high-speed rate.
Always consult the documentation of other units
before attempting high-speed connections.
NOTE
When high-speed signals are received in AES/EBU for-
mat, and the preamble is not correctly detected on
channels 5 and 6, these channels, together with chan-
nels 7 and 8, will be muted.
