ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 81 000 Basic Setup This menu bank has settings for the most fundamental settings governing how the MX-2424 responds to external clocks and control. The items in this bank are: • Control Mode • Frame Reference • Sample Reference • Sample Ref Status • Timecode Type • Sample Rate • Varispeed Rate Control Mode The control mode governs what signal source controls the MX 2424’s transport functions. The control mode choices are described below. Local/ TL Bus In local mode (offline) the front panel transport buttons offer direct control over the all transport functions. When the TL-Bus mode is active and the unit is online, the MX-2424 can function as either a master or a slave to other TL-Bus devices, as set through Setup menu 110 (TL -Bus). This is the default value. Timecode Chase When Timecode chase is active and the unit is online, the MX-2424 will chase incoming LTC.
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 82 MTC Chase When MTC Chase is active and the unit is online, the MX-2424 will chase incoming Midi Time Code. Varispeed Varispeed mode allows for setting playback speed within a range of 87.5% to 112.5% of nominal play speed. Varispeed varies the playback frequency as well as the digital sample clock on the digital output. Frame Reference These settings determine the source of the MX-2424’s video frame reference signal. Automatic Sets the unit to automatically use the sample reference defined by the Sample Reference pull-down menu. This is the default value. Video When set to Video, the MX 2424 will reference the video signal connected to the Video In port on the back of the machine. Sample Reference These settings determine the source of the MX 2424’s digital sample clock reference signal. Internal/Frame Sets the unit to use an internal word clock reference if no external reference is available. This is the default value. Ext Wordclock When set to external word clock Input, the MX 2424 will reference the external word clock signal connected to the machine’s Word Clock In connector. Digital In 1,2 Digital In 9,10 Digital In 17,18 When one of these is selected, the MX 2424 derives its sample clock from the digital expansion I/O (with this setting, the MX 2424 takes its clock from the first two channels of one of the three groups of eight: 1,2 – 9,10 – 17,18). 2 Channel Input This setting allows the MX to take its clock from one of the stereo digital inputs (AES/EBU or SPDIF). You must choose between AES and SPDIF in the 400 Menu tab. Sample Ref Status This is simply a status display for the value selected in the above menu.
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 83 Timecode Type The following timecode types are provided as choices in this setting: • 30ND (default) • 30DF • 25/25 • 24/24 • 29ND • 29DF Sample Rate The following digital sample rates are provided as choices in this setting: • 44056 (44100-) • 44100 • 44144 (44100+) • 47952 (4800-) • 48000 (default) • 48048 (4800+) Varispeed Rate This setting allows for setting a varispeed playback rate. This function allows playback of audio over a range of speeds from 87.5% to 112.5% of nominal play speed. Varispeed varies the playback frequency as well as the digital sample clock on the digital output. The precise speed can be set from ViewNet in increments of .01% over the entire range. This function works by changing the sampling rate of the unit and this is reflected in the sample rate of the digital audio output stream from the MX-2424 , which will vary according to the speed set in this menu. This is different from the jog/shuttle mode because that mode produces a constant sample rate output while scrubbing audio off speed. Note that the Varispeed Mode is mutually exclusive with Timecode Chase or MTCChase and thus the unit cannot be synchronized to an external source while in this mode. The default value is 100%.
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 84 100 Bus Control TLBus Request Sets the status request for the MX2424on the TL Bus. ƒ Off The MX2424 will not be active on the TLBus (default). ƒ Slave The MX2424will request to be a Slave on the TL Bus. ƒ Master The MX2424will request to be the Master on the TL Bus. TL Bus Assigned This setting shows the status assigned for the MX 2424unit on the TL-Bus. Since there can be only one TL-Bus Master at a time, it is possible that some units will be assigned a status other than that requested. (NOTE: When a TL Bus request is made with only one machine, Viewnet MX will display “Master”, regardless of the actual setting on the MX 2424. This is because there is nothing else on the TL Bus to slave to.).
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 85 Ident Request Sets the TL Bus unit ID (Ident) request for the.MX 2424. This value can be any number between 01 and 32, or can be set to Auto, which is the default. When Auto request is on, the system will automatically assign ID numbers to the machines on the TL-Bus. Ident Assigned This is a status display of the MX 2424’s TL Bus ID number.
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 86 200 Transport Record Mode Sets the record mode on the MX 2424. Non-destructive Sets the MX 2424 to non-destructive record mode. In non-destructive record mode, every new recording creates a new audio file on the disk, and recordings can be undone with the Undo button. (Default setting) Tape Mode Sets the MX 2424 to TapeMode, also called Destructive record mode. In TapeMode, each track is always a single audio file, no matter how many punch in and out operations occur on that track. This means that when a track is being recorded, all previous material on the track is being destructively recorded over. There is no editing or undo function for recording TapeMode. Loop Mode Sets the behavior of the MX-2424 when the Loop function is active. The choices for the setting are: ƒ Play Repeatedly Loops between the In and Out points until the transport is stopped (default). ƒ Play Once and Cue Plays once from pre-roll before In to post-roll after Out then cues to pre-roll before In point and stops. ƒ Play Once and Stop Plays once from pre-roll before In to post-roll after Out then stops at end of post-roll.
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 87 Loop Record Sets the behavior of the MX 2424 during Loop Record operation. ƒ Auto Unload On/Off With this setting on, the MX 2424 will create a new virtual track each time a record operation is performed. This is done by unloading the track last recorded on before recording a new one. The MX defaults to Auto Unload Off. Pre-roll Sets the amount of time before the In point (called the pre-roll amount) used for loop play and record functions. The default value is 00:00:03:00 Post-roll Sets the amount of time after the Out point (called the post-roll amount) used for loop play and record functions. The default value is 00:00:02:00. Tape Mode Start TapeMode uses a start time as a basis for time stamping of recorded audio files. Set the TapeMode start time using this setting. The default value is 01:00:00:00. Tape Mode Length TapeMode requires a defined project length. Set the TapeMode length using this setting. The default value is 00:10:00:00. Rollback Length This is a setting you can use to define a “playhead jump”. Pressing the “,” key will move the transport back by the value that you enter in this menu. Pressing the “.” key will advance the playhead forward by the same amount. The default setting is 00:00:10:00.

Analog When selected, input to tracks are taken from the corresponding inputs of the analog I/O module (IF- AN24) if installed. Digital In When selected, input to tracks are taken from the corresponding inputs of a digital I/O module (IF-AE24, IF-AD24, IF-TD24).
ViewNet MX ViewNet MX Version 1.1/1.5 Owners Manual 90 2 Channel in When selected, the dedicated stereo digital inputs are routed to a group of eight tracks, with the left input routed to the odd-numbered tracks (1,3,5,7), and the right input routed to the even-numbered tracks (2,4,6,8). In addition to this menu, it will be necessary to choose which stereo digital I/O to use in menu 462, and to select 2CH as the Sample Reference in Menu 002. Analog 1-8 When selected, input to tracks are taken from inputs 1-8 of the analog I/O module (IF-AN24) if installed. This allows the MX-2424 to be used with analog 8-buss mixers. Digital 1-8 When selected, input to tracks are taken from inputs 1-8 of a digital I/O module (IF-AE24, IF-AD24, IF- TD24). This allows the MX-2424 to be used with digital 8-buss mixers. Digital In rate converter This setting allows real time sample rate conversion in conjunction with the optional IF-AE24 AES/EBU digital I/O. The default is set to off. 2 Channel in rate converter This setting enables the sample rate converters on the stereo AES/EBU and SPDIF interfaces. This setting defaults to off. 2 Channel input source This setting allows you to choose between the stereo AES/EBU and SPDIF interfaces as inputs. 2 Channel output select This setting selects the pair of coincident tracks from the MX 2424 as the output source for the AES/EBU and S/PIF stereo outputs. 2 Channel output encoding This setting allows the chosen stereo digital outputs to send out either AES/EBU (professional) or SPDIF (consumer) protocol. The default setting is professional.
