GETTING WHAT YOU WANT

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
f requently used control
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 but-
ton 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
Touching any fader highlights its parameter and
setting on the display.
• MUTE MACH and MUTE ALL buttons (flanking the

LARC2 CONNECTIONS

Host Port

This port connects LARC2 to the 960L Mainframe. For dis-
tances of 100 feet or less, use the Lexicon 50-foot cable
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 micro-
phone or other audio cable. The cable pin assignment is
shown in Fig. 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 key-
board 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 2A and should have
a 5.5 mm O.D., 2.5 mm I.D. concentric (female barrel) con-
nector, 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.
