Tascam X-48MKII Owner's Manual

TASCAM X-48MKII 35Timebar FormatThe time ruler can be displayed in SMPTE time or insamples.To change this behavior:1 Click the Options menu and select Timebar Format.2 Choose either SMPTE or Samples.You can also show a large display of the timecodeposition in a separate window. Click Time Display inthe Windows menu to open the timecode positiondisplay in a separate window.Clip PropertiesTo specify information about a clip, open the Clip Propertieswindow:1 Use the Smart tool to select a clip.2 Under the Windows menu, select Clip Properties... orpress Control-2 from the keyboard.• You can check file name changes, start pointand end point settings, audio clip movements(timecode contained in broadcast wave files orchanges in playback position), track numbers andother metadata (Coding History).• You can also specify a fade in and fade out timeand shape from this window, mute or lock the clipposition.Another way to edit these values, without opening theClip Properties window, is to click the Info button in thedisplay. A new panel opens up below the transport withthe same clip options.Info buttonNavigating the TimelineThere are several ways to change the playhead position:• Drag the bottom scrollbar left and right, then clickin the track display to jump to that position.• Use the Fast Forward and Rewind buttons, eitheron-screen or on the front panel.• Double-click the timecode position readout andtype in a new location with the keyboard.• Use an external machine control device (see nextsection on Synchronization).Status DisplaysTo the right of the menu displays, you should see a screensimilar to the one above. This shows, from left to right:Current sample rate•Auto input (AUTO IN), all recordings safe (REC SAFE),•Timecode Chase (TC CHASE) and destructive recording(DEST REC) status (indicators appear blue whenenabled)Hard disk usage and remaining recording time•CPU load•Project name•Changing part colors on the trackscreenClick Color Setup in the Option menu to open the ColorSETUP screen where you can change the color of clipbackgrounds, clip waveforms and other items, allowingyou to customize their appearance.These color changes are saved with the project.SynchronizationRequirementsIn order to reliably synchronize the X-48MKII to anotherdevice, two references are required:Location referenceUsually, this is SMPTE (LTC) timecode input through theunit’s TIME CODE IN connector or MTC timecode inputthrough the MIDI IN connector. This tells the X-48MKIIwhere in the timeline to go.Clock referenceA clock reference, typically word clock sent to theX-48MKII through a BNC cable. This tells the X-48MKII howfast to go once it gets to the right location.The X-48MKII can run without an external word clocksource, but it will eventually drift out of sync. (You canalso use a digital audio signal such as AES/EBU as a clocksource.) You will also hear clicks and pops in the digitalaudio if your entire studio is not resolved to a singlemaster clock.Note that video clock is available on the X-48MKII, butit cannot be used as the reference clock. Video clock isonly updated 60 times per second, where word clock isupdated 48,000 times or more per second. Long cableruns can also cause video clock to go out of phase, whichmay cause problems with digital consoles. Video clockon the X-48MKII is used to define the frame edge of theSMPTE input.Word ClockWord Clock sets the playback speed. Once the transportposition has been determined by the SMPTE input, theunit follows the clock rate of the sample clock sourcewhen playing back. (Set the clock source with the Sourceitem on the Sync tab of the SETTINGS screen (select theSettings item from the Windows menu).)5 – Recorder
