Title of Section 960L Owner’ s Maunal Introduction The Model 960L is a multi-channel re v erb processor f or audio prof essionals. It brings to surround all the vir tues and f acilities of the Model 480L— and then some. Like the 480L, it is a multiple-machine system — hardware and software e xpandable.

960L Owner’ s Maunal The Mainframe 1-5 Installation Mounting The 960L mounts in stationar y rac ks with f our scre ws. Make sure the 960L Mainframe is securely screwed into the rac k. For mo ving and in roadcases, be sure that suppor t is pro vided f or the rear of the chassis to avoid possible damage .
1-6 960L Owner’ s Maunal The Mainframe Digital A udio Connections The AES interf ace requires balanced connections, using high-quality , low-loss, controlled-impedance , shielded, twisted-pair cables designed f or data communications, such as Belden 9860 (br aided shield) or Belden 9271 (f oil shield).

960L Owner ’ s Maunal The LARC2 Remote 2-3 In general, the LARC2 ’ s faders and jo ystick are used to control audio parameters of y our choice, while all other buttons select oper ations and parameters . That means you ha v e se v eral f ast ways to oper ate the 960L.
960L Owner ’ s Manual The LARC2 Remote 2-4 Navigating T ypical Displa y Screens The use and navigation of the displa y will be illustrated with the screen shown in Figure 2-4, from Algorithm Edit Mode. Bring up this screen by pressing the EDIT and then ALGORITHM buttons.
960L Owner ’ s Maunal The LARC2 Remote 2-5 About the F aders and Jo ystick The f aders and jo ystick alw a ys control some aspect of the audio , no matter what mode the 960L is in. It is the active control mode that determines which audio parameters are controlled.
The LARC2 Remote Le xicon, Inc. A simple meter bridge above the displa y holds three LEDs per channel. The lowest LED indicates that a signal is present, defined as a le v el of – 60 dBFS or more. When lev els exceed – 6 dBFS , the middle LED lights as a warning of reduced headroom.

960L Owner’ s Maunal Basic Operations Basic Operation This chapter provides a quic k description of how to operate the 960L. Chapter 4, Operations in Detail, provides a more complete description of all av ailable functionality .
Basic Operations Le xicon, Inc. Basically , using the 960L inv olv es only the f ollowing: 1) Setting up the system for the job . 2) Selecting a machine. 3) Loading the Programs and Registers you w ant. 4) Editing the Program or Register parameters with the f aders and jo ystick.
960L Owner’ s Maunal Basic Operations 3-3 Ne xt, press the CONFIG soft button to select the input/output configuration. Depending on the sample rate and input/output configuration y ou select, the 960L can be configured as up to f our vir tual machines, each of which can be programmed individually .
Basic Operations Le xicon, Inc. 3-4 If you selected a cloc k rate of 88.2 or 96 kHz, y ou’ll get a screen like Fig. 3-4, which gives y ou a choice of two processing configurations: 1) Stereo in and out, using one or two machines 2) One machine, with 5 channels in and 5 channels out.
960L Owner’ s Maunal Basic Operations 3-5 (2) Machine Selection In most configurations, the 960L giv es you more than one processing machine to work with, each of which can be programmed individually . T o select the machine you wish to prog ram, use the f ollowing steps: • Hold down the MACHINE k ey on the LARC2’ s control surf ace.
Basic Operations Le xicon, Inc. 3-6 (4) Editing a Program or Register Once a Program or Register is loaded, y ou can edit it to get e xactly the eff ect you w ant.
960L Owner’ s Maunal Basic Operations T o enter Name or Information: • Using the LARC2, use the Increment/Decrement (+/-) ke ys to scroll between char acter positions in the Name or Inf ormation display and the Navigation Arro ws to select the desired character from the matrix below , then press the ENTER ke y to finalize y our selection.

960L Owner’ s Maunal Operations in Detail With more than 200 f actor y Progr ams to choose from, plus up to 1,000 Registers of your o wn creation, y ou’ll probably spend most of y our time with the 960L loading the eff ects you w ant.
Loading Registers Loading Registers is similar to loading Programs . Press the REGISTER K e y instead of the PROGRAM K ey . This will bring up a similar screen (Fig. 4-2) The only diff erences are the use of the word "Register" instead of "Program" and the addition of tw o soft buttons f or labeling.
960L Owner’ s Maunal Operations in Detail The LARC2’ s CONTROL ke y provides access to the 960L ’ s wordcloc k, input/output configuration, and system inf ormation. Note that only three soft buttons operate in this mode. The f aders and jo ystick remain assigned to whate v er audio parameters are on the V -P age.
Operations in Detail Le xicon, Inc. Use the Right Navigation Arro w to get to the Rate displa y . F or inter nal wordclock, y ou must select the e xact rate , as sho wn in Fig. 4-3. F or e xter nal wordclock via the BNC or AES inputs, y ou need only select 44.
960L Owner’ s Maunal Operations in Detail Note: As shown in these tab les, AES inputs (and outputs) ha ve two channels per ph ysical connection. On the back panel, these are labeled 1-2, 3-4, etc.
Operations in Detail Le xicon, Inc. In 5-Channel configurations, all a vailable machines are configured f or surround or other multi-channel uses . F or one configuration (Fig. 4-7), one machine is configured as 5-in/5-out, the other as 2-in/5-out, both sharing the same output channels.
960L Owner’ s Maunal Operations in Detail There are also 8-in/8-out configurations (Figure 4-9). No effects processing is a vailable in this configur ation, but it is useful f or wiring checks and diagnostics. Contr ol Mode: Clocks, Configuration, and System Screens, continued 4-7 Figure 4-8 — 2-in/5-out configuration at 44.
Operations in Detail Le xicon, Inc. Analog and Digital I/O The 960L ma y be set f or either analog or digital input. In the Configuration e xamples sho wn abov e, the inputs are analog, as shown b y the legend "AN1" abov e each input number .
960L Owner’ s Maunal Operations in Detail The 960L ’ s Programs and Registers can be edited in se v eral wa ys: • Changing the settings of the parameters with the f aders and jo ystick • Adjus.
Operations in Detail Le xicon, Inc. Editing with the Joystic k Check the Jo ystick Status Displa y to see what parameters are currently assigned to the jo ystic k and what their current settings are. Note whether the JO YSTICK K ey on the LARC2 control surf ace is illuminated or not.
960L Owner’ s Maunal Operations in Detail Editing Inputs and Outputs The LARC2’ s joystic k can be used to place any input or output signals anywhere in the soundfield.
Operations in Detail Le xicon, Inc. When you press the JO YSTICK key , the input position jumps to the jo ystick position, and the setting dot turns from red to green, highlighting the jo ystic k cursor (as shown on the Jo ystick Map and on the smaller map of the selected input).
The 960L Surround P anning Rules The 960L does not produce a phantom center in surround modes, and no signal will appear in both the left and right output channels, no matter where y ou set the jo ystic k. In other words, panning across the front is either betw een Left and Center or between Right and Center .
Operations in Detail Le xicon, Inc. Editing, Continued 4-14 Figure 4-21 — Edit V -P age screen; programming fader s. The V -Pa ge and Parameter Reassignment • Press the EDIT ke y on the LARC2 control surf ace. • Press the V -P A GE soft b utton.
• Pressing the J-STICK soft button pops up a numbered list of the two jo ystick ax es and their assigned parameters (Figure 4-22). T o assign your selected par ameter to a jo ystick axis , type the axis number on the Numeric K e ypad. Note: Y ou must already hav e selected a parameter bef ore you get to this screen.
Operations in Detail Le xicon, Inc. When you’v e edited a Program or Register until it just meets your needs , y ou can store it as a Register and label it f or future use.
960L Owner’ s Maunal Operations in Detail The 960L provides tools to help y ou organize the registers y ou make. T o access the tools, press the REGISTER ke y and then the OPTION soft b utton.
Operations in Detail Le xicon, Inc. 4-18 Edit T ools f or Register s Pressing the EDIT soft button accesses three tools: 1) Copy Bank -- When 1 is pressed on the Numeric K e ypad, the contents of the currently selected Program or Register Bank are copied to an internal scratchpad.
