This first part establishes basic operating parameters for each input. Be aware, any reference to the camera
returns/line-level inputs are channels 7 – 10 and the mic-/line-level inputs are channels 1 – 6.
The first stop is the
Analog Input Channel Setup page
}. You can get there by pressing this sequence:
(
SETUP
key
once
press the number button for the channel to want to update/verify).
Switching Between Mic- and Line-Level Input
(Analog Only)
To toggle a channel between Mic-level and Line-level, click on the
TYPE
button
and turn the
MENU
knob
to
change the selected item. Once chosen, press the
MENU
knob
to accept the change.
Enabling the High Pass Filter
(Analog / Digital)
To set the highpass frequency, click the
HPF FREQ
button
and turn the
MENU
knob
to change the selected value.
Once chosen, press the
MENU
knob
to accept the change.
NOTE:
The valid frequency range is
30 Hz
to
240 Hz
.
To enable the filter, click the HPF button and turn the
MENU
knob
until
ON
is displayed and then press the
MENU
knob
to accept the change. Obviously, if you wish to disable the filter, select
OFF
.
Enabling 48 VDC Phantom Power
(Analog Only)
Some microphones require external power to operate. The Nomad supplies 48 VDC and 40mA divided between
the mics. The Nomad does not supply 12T power, which is required by some older microphones. If you use
microphones requiring 12T power, check with your local audio dealer for phantom to 12T power converters.
To enable phantom power, click on the
PHANTOM
button
and change the parameter to
ON
.
IMPORTANT:
To protect equipment from damage, the Nomad does not allow you to apply power to any
channel set as a line-level input.
Adjusting the Trim (Analog / Digital)
To change the trim, click the
TRIM
button
and adjust the parameter as required.
NOTE:
The valid trim range is
-20 dB
to
30 dB
.
Adjusting the Delay
(Analog / Digital)
The delay in the Nomad provides a way to monitor various input sources that may come into the Nomad at
slightly different times. For example, wireless microphones typically require 0 to 8 ms of delay to avoid phasing
associated with mixing wired and wireless sources to a common mix track. The delay does not affect the input
signals actual timecode; it simply allows the signal to align with other sources mixed with it. Both analog and digital
inputs can have a delay added to them.
To change the delay, click the
DELAY
button
and adjust the parameter as required.
Enabling the Limiter
(Analog / Digital)
All of the input limiters use one common set of parameters. All that can happen here is to enable or disable it. To
change its setting, click on the
LIMITER
button
and change it as required.
Enabling the Notch Filters
(Analog / Digital)
There are two notch filters, identical in function. The top line of each pair enables/disables that particular notch
filter and the bottom line of each pair sets the center frequency.
To change the frequency, click the bottom
NOTCH#
button
of the pair and change it as required.
To enable it, click the top
NOTCH#
button
of the pair and change it to
ON
.
NOTE:
The valid filter range is
20 Hz
to
18000 Hz
.
Inverting the Phase
(Analog / Digital)
To change the phase, click on the
PHASE
button
and change it to
INVERT
.
