The upper area of the Titan Control Panel contains the main settings for the Titan unit.
The Titan model and serial number are displayed at the top of the Unit settings area. Note that the currently-installed firmware version of the Titan unit can be displayed by hovering the mouse cursor over this text.
The Sample Rate and Sync Source controls allow the unit's reference sample rate and synchronization source to be selected. For more details, see the Synchronization section.
NOTE: If an external sync source such as DI or Wordclock is selected, but is either absent or at a different rate from the selected sample rate, the unit reverts to local (internal) sync at the selected sample rate. If the reference is later applied at the appropriate rate, audio is re-enabled. Note that during Stand-alone operation an external sync source is allowed to control the unit's sample rate.
NOTE: It may not be possible to change the sample rate whilst any of Titan's ports are in use by an audio application (e.g. a DAW). In this case it is necessary to disconnect the ports from the application before changing the sample rate, or (where possible) to change the rate from within the application.
The ADAT mode control selects the number of supported ADAT inputs and outputs as follows:
In ADAT4 mode at sample rates of 88.2kHz and 96kHz, SMUX mode is used. By default, ADAT ports are disabled to ease load on the host computer. For more information, see the Digital inputs and Digital outputs sections.
NOTE: Changing the ADAT mode causes changes in the number of input and output channels reported to the host computer by Titan. It is therefore advisable to close your DAW application before changing the ADAT mode, and to restart it again afterwards, in order to ensure reliable operation.
The FP Meters control allows the front panel meters to be switched between the analogue and S/PDIF inputs, and the analogue and S/PDIF outputs. For more information, see the Metering system description.
The Clock Out control can be used to cause the Wordclock output to produce Baseclock or 256x clock instead of Wordclock if required. For more details, see the Synchronization section.
The LED Level control allows the brightness of the LEDs on Titan's front panel to be adjusted to suit ambient lighting conditions.
In Windows ASIO systems, the audio delay through the input and output buffers is set by the Buffer control and is entered in samples. The buffer time may be automatically adjusted by the software when the sample rate is changed. The Base control determines how many ASIO buffers are queued, allowing improved dropout resilience, and is entered in ms. In general, it is better to keep the buffer time quite long as this reduces the risk of audio glitches, as described in the Stability and latency section. Titan's low-latency on-board foldback mixing facility reduces the need for the low latency in the driver. Note that the WDM buffer length is set by Windows; in Mac systems, buffer latency control is handled by OS X.
Below the Unit Selector is the Identify button. This can be latched on or off. In the on state (high-lit red) the LED in the standby switch of the associated unit flashes. This allows identification of each unit in a multi-unit system (if supported).
The Verifile button should normally be lit green to show that all of the analogue input channels are producing Verifile-encoded data. It is possible to switch this function on and off, but switching it off is via a confirmation box since it is strongly recommended that Verifile encoding is enabled at all times. Verifile encoding causes no audible performance degradation, but ensures that subsequent Verifile checking is always possible.
The blue Help button ('?') opens the online version of this manual in a browser window.
The red Save and the orange Load buttons save and load Titan settings to and from disk.
The green Verifile Checker app button opens the Verifile Checker app.
