PUSH-BUTTON KNOBS
On the 1248 and 8M, the knobs (Figure 6-2) are
push-button digital rotary encoders. Push the
knob for the function labeled in blue.
Figure 6-2: Push the knob to activate the functions labeled in blue.
16A BUTTONS
Instead of knobs, the 16A interface has equivalent
buttons. Use the up/down arrow buttons to scroll
through menus or settings.
Figure 6-3: Buttons on the 16A front panel.
AUTOMATIC CHANNEL FOCUS
When turning the knobs (on the 1248 or 8M) to
adjust the preamp gain on a mic channel, the
display switches to a larger, horizontal meter with
numeric readouts for precise setup. A few seconds
after you stop turning the knob, the display returns
to the default view.
“PIN” CHANNEL FOCUS
When viewing a channel’s horizontal meter, push
its knob (on the 1248 or 8M) to “pin” the LCD’s
focus on the large meter view. The view is “pinned”
to show the horizontal meter until the active
channel’s knob is pushed again. Switch directly to
another channel’s horizontal meter by pushing or
turning its knob. Push the selected channel’s knob
again to unpin.
TRIM
On the 1248 and 8M, push TRIM (Figure 6-2) to
display the preamp gain settings for all mic inputs
simultaneously, instead of viewing only the
channel you are adjusting. You can then use the
channel knobs to adjust each channel while
viewing its setting relative to the other channels
being displayed.
ID
Push ID (Figure 6-2) to immediately view the
device’s network information, including its IP
Address. Push back to return to the meters.
MENU NAVIGATION
Push SELECT (or SEL) to access the main menu,
which provides settings and status information.
Main Menu
On the 1248 or 8M, turn the SELECT knob to
scroll through the menu settings on the left side of
the LCD. On the 16A, push the up/down arrow
buttons to scroll through the equivalent menus and
settings.
Push SELECT (or SEL) to enter the selected sub-
menu (column of options to the right) or to select
the currently highlighted parameter.
Push BACK to go to the parent menu.
To exit the menu entirely, push BACK repeatedly
until the menu disappears from the display.
Device menu
The Device menu provides information about the
device, such as its name and connection mode
(Thunderbolt, USB, or AVB).
