    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.

     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.

    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%.

    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.).

    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.

    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.

    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.

    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.
