Chapter 3: Installing andConfiguring C|24Installing C|24C|24 can be set on a level table top or mountedin a console or desk.Wherever you install C|24, make sure not toblock air circulation to the vents on the back ofthe unit.Connecting Power to C|24C|24 comes with a dedicated external powersupply that has an IEC standard AC receptacle.This connector accepts a standard AC powercable.To connect power to C|24:1 Connect the external power supply to theconnector marked “To Ext PSU” on the backpanel of C|24. Make sure the connector is orientedcorrectly before securing the connection.2 Connect the included AC power cord to theexternal power supply.Connecting C|24 to theComputerC|24 communicates with Pro Tools usingEthernet. This connection uses a standard RJ45connector. If you are connecting C|24 directly to yourcomputer, use a crossover Ethernet cable (one isincluded with C|24). If you are connecting C|24 to an Ethernet hubor network, use a standard Ethernet cable (notincluded).If C|24 will be the only Ethernet device connectedto your computer:1 Connect one end of the included crossoverEthernet cable to the Ethernet port on the backpanel of C|24.2 Connect the other end of the crossover Ethernetcable to the appropriate Ethernet port on thecomputer.3 Connect the other end of the AC power cordto a power source.Chapter 3: Installing and Configuring C|24 15

If you have more than one Ethernet device inaddition to C|24:1 Connect one end of a standard Ethernet cable(not included) to the Ethernet port on the backpanel of C|24.2 Connect the other end of the Ethernet cableto a powered Ethernet hub (do not use any portlabeled for LAN connection).3 Connect the Ethernet hub to the appropriateEthernet port on the computer.Shut down your system in this order:1 Turn off monitor amplifiers or self-poweredspeakers.2 Turn off all Pro Tools audio interfaces.3 Shut down the computer.4 If you are using MIDI equipment, turn offMIDI interfaces and other MIDI devices.5 Turn off the C|24.6 Turn off external hard drives.Starting Up and ShuttingDown a Pro Tools SystemYour C|24-based Pro Tools system should bestarted up and shut down in a specific order.Start your system in this order:1 Turn on external hard drives first. Wait 10 to15 seconds for them to come up to speed.2 Turn on the C|24.3 If you plan to work with MIDI equipment,turn on MIDI interfaces and other MIDI devices.4 Turn on all Pro Tools audio interfaces.5 Turn on the computer.6 Turn on monitor amplifiers or self-poweredspeakers.Configuring C|24All C|24 software is included when Pro Toolssoftware is installed. The Pro Tools installerplaces the C|24 Personality file in the Controllersfolder inside the Pro Tools folder.Refer to the Getting Started Guide that came withyour system for instructions on installing or updatingPro Tools software.Updating System FirmwareEach release of Pro Tools software includes currentC|24 firmware. When you declare a C|24unit in the Pro Tools Peripherals dialog,Pro Tools prompts you if a firmware update isavailable.If you are prompted to update firmware, followthe on-screen instructions to load the latestfirmware to the C|24.16C|24 Guide

Establishing CommunicationBetween C|24 and Pro ToolsCommunication between C|24 and Pro Tools isconfigured by declaring the unit in Pro Tools.To declare C|24 in Pro Tools:1 Choose Setup > Peripherals, and click EthernetControllers.Naming C|24You can set a name for a C|24 unit, so that it canbe easily identified on a network shared withother Ethernet controllers. You can name C|24from Pro Tools, or directly from the unit inUtility Mode.To name C|24 in Pro Tools:1 Choose Setup > Peripherals, and click EthernetControllers.2 Click Name Units. Any declared controllerswill appear in the Ethernet Controller Unitswindow.Ethernet Controllers page in the Peripheral dialog2 Select Enable. Pro Tools scans the Ethernetconnection for any Ethernet controllers connectedto the system.3 Select the C|24 from the pop-up menu forController #1.If you are connected to a network, any Ethernetcontrollers available on the network will be displayedin the pop-up menu, as follows:Naming the C|243 Enter the name for the C|24 and click OK.4 For information on naming C|24 from theunit, see “Unit Name” on page 116. Bold text indicates a connected unit. Italic text indicates an offline or disconnectedunit. Dimmed text indicates that the selected unitis in use by another Pro Tools system.4 Click OK to close the Peripherals dialog.When communication is established, Pro Toolsdisplays colored outlines identifying the tracksfocused on C|24.Chapter 3: Installing and Configuring C|24 17

Using Additional Control Surfaceswith C|24When a C|24 is declared in Pro Tools, the use ofadditional control surfaces is subject to the followingrestrictions: You can use a MIDI-based control surface(such as a Digidesign Command|8) or anotherMIDI-based controller (such as the DigidesignSurround Panner Option) at the same time as aC|24. A MIDI control surface will mirror the first8 channels on C|24. You cannot use another Ethernet-based controlsurface (such as an ICON worksurface, Control|24,or ProControl) at the same time as aC|24.

The default gain reduction is 6 dB.Headphone, Cue, and LS outputs are not affected.The Mono switch lights to indicate thatit is active.Control Room Input SelectorsControl Room Input selections are mutually exclusive(X-OR) unless the Sum switch is engaged,when they are additive.Main SwitchThe Main switch routes the Main Surround input(Pro Tools In 1-6) to the Control Room outputs.The Main switch lights to indicate that it isactive.Alt Sur SwitchThe Alt Sur switch routes the Alternate Surroundinput (Surround In 1-6) to the Control Roomoutputs. The Alt Sur switch lights to indicatethat it is active.Stereo 1 and Stereo 2 SwitchesThe Stereo 1 and Stereo 2 switches route the ExternalStereo inputs (Ext St 1 and Ext St 2) to theControl Room outputs.These stereo inputs appear in the Left and RightControl Room output channels only and are excludedfrom the C, Ls, Rs, and LFE channels.The Stereo 1 and Stereo 2 switches light to indicatethat they are active.62C|24 Guide

Sum SwitchThe Sum switch causes Control Room Inputs tobe additive instead of mutually exclusive(X-OR). When active, the Sum switch temporarilybypasses any Trim values currently appliedto any of the inputs.The Sum switch latches on, allowing you to selectthe inputs to be summed. The Sum switchlights to indicate that it is active.Monitoring AFL/PFL Signals(Pro Tools HD Only)If you are working on a stereo session, you canmonitor soloed tracks in AFL or PFL Solo modeby routing the AFL/PFL path to one of the C|24External Stereo inputs and summing that Stereoinput with the C|24 Main input.To monitor AFL/PFL signals:1 Connect an unused pair of outputs on youraudio interface to one of the External Stereo inputson C|24.2 In the Pro Tools I/O Setup window, select thepair of audio interface outputs as the AFL/PFLoutput path.3 Select the Main output path to be mutedwhen you solo a track in AFL or PFL mode.4 In the Monitor section of C|24, press the Sumswitch so that it is active.5 Activate the Main input and the External stereoinput.When AFL or PFL Solo mode is selected and atrack is soloed, the Main input is muted and theAFL/PFL signal is heard on the External Stereoinput.Submixer OutputWhen the To Monitor switch in the Line Submixercontrols is engaged, the stereo outputfrom the Submixer is routed internally and automaticallysummed with the Left and Rightchannels of the current Control Room Input selection,and are excluded from the C, Ls, Rs, andLFE channels. Any Trim values applied to thecurrent input are also applied to the summedSubmixer output.Trimming Monitor Section GainControlsThe gain controls in the Monitor section can beadjusted to establish channel balance and levelmatching between inputs.Control Room Main OutputsEach of the Control Room Output channels canbe trimmed individually. Available trim valuesrange from –30 dB to +10 dB, in 0.5 dB steps.To trim the level for an individual output channel:1 Hold the Output Channel switch until theswitch flashes.
