Modular Multitrack Recorder - Tascam

Setup Menu Details
This section contains detailed notes on the operation of some important Setup menu parameters.
Control Mode
The MMR-8 will always operate in one of seven Control modes. The default Control mode, which is how
the MMR-8 starts up when the unit is first installed, is called the Local/Bus Control Mode.
To change the Control mode, select Setup menu 000 (press SETUP to display the Setup menus).
Whenever the MMR-8 is powered up, the first menu displayed will always be menu 000 (“Control
Mode”). Afterwards, the menu displayed when entering Setup mode is the last menu displayed. Once
Setup menu 000 (“Control Mode”) is displayed, press TRIM to change the Wheel and the Up/Down
arrow keys to scroll through the seven menu choices under Setup menu 000. Once the desired operating
mode is displayed, press STO (the Store key) to select that choice. This immediately switches the various
parameters to the new control mode, typically causing several LEDs to change status according to the
new parameters. To exit Setup mode, press SETUP or the CLR (Clear) key.
Following is a more detailed description of the seven control modes that are supported by the MMR-8:
Local/Bus
In local mode (offline) the MMR-8 functions like other stand-alone digital 8-track recorder/players. No
external sync signals are required. The front panel transport keys offer direct control over the audio track
playback. Individual tracks can be put into record ready and then audio can be recorded to the hard drive.
When placed into bus (online) mode, the MMR-8 can function as either a master or a slave to other MMR
bus or Lynx bus devices, as set through Setup menu 110 (MMR Bus) and Setup menu 120 (LYNX bus).
Time Code Chase
In Time Code Chase, the MMR-8 will slave to the time code coming from one of the time code inputs on
the rear panel (VITC In or Time Code In) when it is placed Online. In this mode the time code input must
have valid time code in order for the MMR-8 to chase, lock, and synchronize itself to the incoming time
code. Pressing any of the transport keys will take the MMR-8 off-line and allow local control at any time.
Placing the MMR-8 back online will cause it to lock to and chase the selected time code once again.
Biphase Chase
In Biphase Chase, the MMR-8 chases, interlocks, and synchronizes to a biphase or tach/dir. signal on one
of the four Biphase Inputs (the active input is determined by the Sync Group number set in menu 100).
The system locks and plays audio at speeds from 0 to 1.5 times play speed in both forward and reverse
directions. The MMR-8 can then serve as a master for other devices on the MMR or Lynx buses.
Biphase Transport
The MMR-8 functions as the master for a film projector connected to the Biphase Output. The front panel
transport keys will control both the MMR-8 and the film projector (and any other devices slaved to the
MMR-8 Biphase output). The MMR-8 internally chases the biphase signal so the audio functions match
those of Biphase Chase mode.
