Lexicon 480L Owner's Manual About the Rear Panel Main Inputs (L & R) The left and right Inputs accept 3-pin male XLR connectors. They are electronically balanced and (optionally) transformer isolated. Either pin 2 or pin 3 can be used as high, but to maintain polarity when transferring data to the digital domain, pin 2 should be high. Pin 1 and either pin 2 or pin 3 of each input must be grounded for unbalanced operation. Input impedance is 30 kilohms in parallel with 100 pF. Inputs accept input levels from +6 to +24 dBm. Main Outputs (L & R) The left and right Main Outputs accept 3-pin female XLR connectors. They are electronically balanced and (optionally) transformer isolated. Either pin 2 or pin 3 can be used as high, but to maintain polarity when transferring data to the digital domain, pin 2 should be high. Pin 1 and either pin 2 or pin 3 of each output must be grounded for unbalanced operation. Output impedance is 33 ohms, and levels up to +24 dBm are possible. Aux Ouputs (L & R) The left and right aux outputs are identical to the Main Outputs, except that they are used as secondary outputs when split or cascade modes are selected. Important. Reversing polarity on either input or output connectors can produce audible phase inversion effects. Improper phasing in the stereo path can create a weak or thin mix. Ensure that inputs and outputs are wired consistently. MIDI Connectors MIDI IN receives MIDI information from other MIDI-equipped devices. MIDI THRU retransmits MIDI information received at the MIDI In connector, without any change. MIDI OUT is used to transmit Automation data. Lexicon Digital Audio I/O Connector This DE9 connector provides PCM 1610- compatible digital I/O. It has 18-bit word length capability and can be slaved to a 48 kHz, 44.1 kHz or 44.056 kHz external word clock. 480L Rear Panel LARC 1 Connector This DE9 connector connects the mainframe to the Lexicon Alphanumeric Remote Control (LARC) via a flexible 50-ft cable (supplied) Automation Connector The Automation Connector is provided for future computer control and automation features. Important: Never connect a LARC to this connector. LARC 2 (Thru) Connector This DE9 connector allows connection of a second LARC. It also allows the 480L to be connected to a 224XL, with both units under control of a single LARC. A 10 ft cable is available from Lexicon for this application. Power Connector and Fuse Holder Cartridge The Power Connector is a standard 3-pin IEC power connector. The Fuse Holder Cartridge contains the AC mains fuse(s). The voltage changeover card is also contained in this compartment. Read Appendix D for voltage changeover information. 1-2
Installation and Audio Connections About the Front Panel Cartridge Slot The Cartride Slot accepts both ROM-based program cartridges, and Nonvolatile RAM cartridges for additional memory storage. The 480L is shipped with one Nonvolatile Memory Cartridge, providing five banks of portable register storage. A write-protect switch prevents accidental erasure of contents. Front Panel Latch The front panel is hinged at the bottom; pull on the handle to open. Keep the front panel closed during normal operation to maintain dust filtration. Power Switch and Indicator The Power Switch turns the 480L on and off; the indicator lights when the unit is on. A lithium battery retains the data memory when power is off or disconnected. 480L Front Panel 1-3
