960L Owner’s Maunal The LARC2 Remote
2-3
In general, the LARC2’s faders and joystick are used to
control audio parameters of your choice, while all other
buttons select operations and parameters. That means
you have several fast ways to operate the 960L.
•Mode Buttons give you direct access to the most
frequently used control actions.These buttons are:
PROGRAM, REGISTER, BANK, STORE, EDIT,
CONTROL, and MACHINE. The functions of some
buttons are implied by their names, and all are
explained below. When selected, each button
glows red.
•ENTER is used to complete an action.
•The Numeric Keypad lets you quickly select any
numbered option on the display.
•Navigation Arrows let you move up, down, or
sideways within the display to select the action you
want.
•Increment and Decrement (+/-) Buttons can be
used to select items from lists or to make fine
adjustments to parameters.
•Soft Buttons are context sensitive. Their labels
therefore change dynamically and appear at the
bottom of the LCD display, just above each button.
Additional LARC2 controls include:
•Joystick, primarily for input and output panning, but
assignable to any desired parameters.
•JOYSTICK Button activates and deactivates
the joystick.
•FINE ADJ Button toggles faders to and from
fine-adjustment mode.
•Lexicon Button temporarily returns operation to the
most recently loaded Program or Register for quick
sonic comparison.
•Faders are touch-sensitive and motorized. Their
positions are automatically updated (auto-nulling)
to reflect the current values of their assigned
parameters. The parameters controlled by each
fader and their current settings are shown on the
display, just above the soft-button labels. Touching
any fader highlights its parameter and setting on
the display.
•MUTE MACH and MUTE ALL buttons (flanking the
numeric keypad’s "0") mute the output
of the currently selected machine or the outputs of
all machines.
Host Port
This port connects LARC2 to the 960L Mainframe. For
distances of 100 feet or less, use Lexicon No. 022-
14400 50-foot cables. One 50-foot cable is supplied
with LARC2. For longer distances (up to 1,000 feet) use
computer-grade cable with shielded twisted-pairs, for
example Belden 9860 or 9271. Do not use microphone
or other audio cable. The cable pin assignment is
shown in figure 2.3. For distances over 100 feet,
LARC2 requires an external power supply, as described
below.
Aux Port
You can connect a standard PS/2 computer keyboard to
LARC2 via this port. This will allow faster text entry in
NAME and INFO fields (see Chapter 4, Operations in
Detail). "Hot plugging" the keyboard is not
recommended. The keyboard should be connected
before power is applied to the 960L.
External Power Connector
The LARC2 must be powered by an external power
supply when located greater than 100 feet from the
960L. The power supply should deliver 12VDC at 2 A
and should have a 5.5 mm O.D., 2.5 mm I.D.concentric
(female barrel) connector, with the positive voltage on
the inner contact. See the Lexicon web page
(www.lexicon.com) for a current list of external power
supplies and vendors.
