Tascam X-48MKII Owner's Manual

TASCAM X-48MKII 15THRU This connector passes the Word Clock signalpresent at the Word Clock IN through withoutadding any delay. This allows additional devicesto be locked in a daisy-chain fashion in configu-rations where there is no way to directly distrib-ute clock from a single source.Analog AudioThe IF-AN24X provides 24 channels of balanced analoginputs and 24 channels of balanced analog outputs.The X-48MKII can be configured to one of five possibleoperating reference levels by applying the appropriatesoftware settings. Please refer to ‘Analog I/O OperatingLevel’ (page 20) for details.The analog DB-25 pinout is pictured below:CAUTIONUse only DB25 cables specified by the manufacturer as“Analog” cables. Many cables look the same onthe outside.Synchronization and ControlThis section will deal with the physical connectionsneeded in various synchronized applications. For detailsabout the appropriate software settings, please refer tothe ‘Synchronization’ section (page 35).MIDIThere are two MIDI connectors on the rear of theX-48MKII. These are used for MIDI Machine Control (MMC)and MIDI Time Code (MTC).IN This connector receives MTC, which theX-48MKII can chase, or MMC, which theX-48MKII can respond to. The front panel MIDILED will illuminate when valid MIDI signals arepresent at this connector.OUT This connector outputs MTC any time thetransport is in motion. That MTC output followsthe frame rate and output options set for LTCoutput. MIDI machine control (MMC) open loopand closed loop are supported.Time CodeThere are two 1/4” TRS connectors on the rear of theX-48MKII, used for sending and receiving time code (LTC).These connectors are balanced to allow for long cableruns with minimal interference. Please refer to pages 37-40 for details on time code options.FootswitchA momentary footswitch may be connected to this 1/4”TS connector for hands free play, stop, and punch-in/outoperation.NOTETo operate correctly, a footswitch must be connectedbefore the X-48MKII is powered on.Remote (Sony 9-Pin)This is also known as “P2” or “Sony P2” or “RS-422”. Variousrecording consoles and video controllers support thisprotocol for transport control and track record enable.This requires a specifically constructed cable. If in doubt,pre-made RS-422 cables are readily available.Pin No. Controlling end Non-controlling end1 GND GND2 RX– TX–3 TX+ RX+4 TX common RX common5 Spare (NC) Spare (NC)6 RX common TX common7 RX+ TX+8 TX– RX–9 GND GNDVideo Reference (Tri Level Sync)IN When the X-48MKII is used in a film/video postproduction environment, it may be necessaryto resolve a consistent sample range with thetime code edge. A video reference (blackburst)signal applied to this connector makes thispossible. Please refer to page 19 for details onconfiguring the use of signals present at thisconnector.Tri Level Sync is the video reference signal used for HighDefinition Video. This connector automatically senses thetype of signal present.THRU The video reference signal present at the INconnector is passed through out thisconnector without additional processing delay.This allows for daisy-chaining another device,after the X-48MKII, which requires a video refer-ence signal.3 – Setup
