IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] Use the up/down arrow buttons to choose the word size from the following options: "16 bits", "20 bits" or "24 bits". The display will briefly display the "Saving new setting" screen and then revert to the "select bit size" screen. Press MENU as many times as necessary to do one of the following: · · Configure another pair of channels. Exit this option. DL351 Modular I/O Operator Manual 21 Chapter 6: Operation This chapter explains the default screen. There are no operating procedures associated with the DL351 Modular I/O, as it is operated solely from the PRO6 Control Centre. Refer to PRO6 Control Centre operator manual (part number DOC02-DL3) for more details. Default screen The default screen appears after the unit has been switched on and has powered up. The following diagram shows a typical default display. 1 3 1 2 Company name and model of unit. Unit ID number. 2 3 Description of unit. Checking the CBMA/software versions You can check the CBMA and host software versions of the DL351 Modular I/O during normal operation. To do this, see "To view the CBMA version number" on page 18 and "To view the current host software version" on page 18, respectively.

DL442 analogue output module; see "DL442 analogue output module" on page 30. DL443 analogue insert input/output module; see "DL443 analogue Jack I/O module" on page 30. DL452 digital in/out (AES/EBU) module; see "DL452 digital I/O module" on page 31. Details of how to replace a module can be found in Appendix D "Replacing An I/O Module". DL441 analogue input module The DL441 analogue input module provides eight balanced line (or mic) inputs. Its rear panel houses eight input XLRs, each with a check and a 48V LED. The line inputs may be used as simple unity gain inputs to the PRO6, such as insert returns. However, there is also provision for gain adjustment in 5dB steps from -5dB to +40dB. This allows very high signal levels to enter the system and means that the same hardware can be used for mic inputs, if required by the system. When used for microphones the input can also provide 48-volt phantom power. 2 3 1 2 Eight XLR analogue mic/line inputs. 1 3 Green check LED illuminates to show when a channel is selected on a console. These are controlled by the console and are used as a visual aid to locate specific connectors. Red 48V LED illuminates to show that 48V phantom voltage is on. DL351 Modular I/O Operator Manual 30 DL442 analogue output module Appendix C: I/O Modules The DL442 analogue output module provides eight balanced line outputs. Its rear panel houses eight output XLRs, each with a check and a mute LED. The line outputs have no analogue level adjustment. 2 3 1 1 2 Eight XLR analogue outputs. [. . . ] When fitted properly the Volex plug locks into place, preventing it working loose, or being inadvertently knocked loose or pulled out. For details of how to fit/remove a Volex plug, see "Power" on page xi. DL351 Modular I/O Operator Manual Powering the PRO6 system 51 Powering the PRO6 system The following details the recommended power up and power down procedures for the PRO6 system. Note: If you are in any doubt as to how to switch the DL3n1 units on/off, refer to their operator manuals. >> To power up the PRO6 system Important Note: DO NOT switch on the speaker sub-system until after the start-up of the PRO6 system has been completed.
