960L Owner’s Maunal The LARC2 Remote

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 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.

LARC2 Connections

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.

	5	4	3	2	1

* Not connected if external power supply is used.

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.

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.
