connected to this jack, activating it will always send a
command to the host computer. Note that in MIDI CTRL mode these controls also send
programmable MIDI messages to the FW-1082’s
physical and virtual MIDI outputs.
Dedicated Modifier Keys
There is a dedicated modifier key on the FW-1082’s
control surface: the
SHIFT key. This key has no effect
when pressed alone.
However, you can press and hold it to modify the
functions of a number of other keys when pressed
together with it.
These functions are chiefly dictated by the host
application software.
In most DAW applications, pressing and holding the
REC key and then pressing a channel’s SEL key will
generally arm the selected track(s) for recording.
Setting and checking clock rates
The FW-1082’s audio clock rate and source can be
checked or changed directly from the control surface.
The software Control Panel can also be used to do
this as described in “Settings tab” on page 26.
WARNING
The FW-1082 outputs produce a “thump” when the
power is turned on. To avoid any damage to hearing or
equipment, turn the volume of the monitoring system
down, or make sure it is turned off, and do not wear
headphones connected to the FW-1082 when powering
the unit up or down.
1 Put the FW-1082 into MON MIX mode by press-
ing the MON MIX key which then lights.
2 Press one of the clock rate keys to select the
sampling frequency:
• 96kHz (EQ HI–AUX 1/5)
• 88.2kHz (EQ HI MID–AUX 2/6)
• 48kHz (EQ LO MID–AUX 3/7)
• 44.1 kHz (EQ LOW MID–AUX 4/8)
3 Press either of the clock source keys:
• INTERNAL ( EQ/PAN ) – Internal Clock
• D IN ( AUX1–4 ) – S/PDIF Input
When the FW-1082 is in MON MIX mode, these rate
and source keys and indicators light to display the
current clock settings. Note that these keys have no
meaning in
MON MIX mode other than clock settings.
Expected Sample Rate If the S/PDIF input is
selected as the clock source and it does not have a
usable clock signal, the
CLOCK indicator flashes to
indicate a problem, and the unit switches to its own
internal clock and waits for a valid clock signal. If
the sample rate is off by 3% or more, the FW-1082
switches to the incoming clock, and the nearest sam-
ple rate indicator blinks slowly.
