Titan FAQs, Tips and Techniques
|?||How can I tell what version of firmware is in the hardware?|
|From the control panel software, hover the cursor over the serial number. The firmware version is reported in the tool-tip that appears:
Titan Control panel showing firmware version - Lyra and Atlas are similar
|?||Which operating system do I need?|
|For Windows, you'll need Vista or later. There are drivers for 32-bit and 64-bit systems.
Operation under Windows 7, 8, 8.1 and 10 have been tested. It’s always best to use the most recent drivers and firmware, these are necessary for Windows 8, 8.1 and 10.
For Mac, OS X 10.5 or later on an Intel platform.
Titan, Lyra and Atlas are fully compliant with El Capitan when using the up to date Control Panel app and firmware (v1.11 or higher).
|?||I've installed the control panel software on my Windows Vista PC, but it doesn't work. How do I fix this?|
|Some Windows Vista versions mistakenly associate a Prism Sound USB audio device with Windows' built-in UAC1 driver rather than the Prism Sound UAC2 driver, even though the UAC2 driver has been installed correctly.
To fix this, you must correct the association manually using the Windows Device Manager:
Windows will now associate the Prism Sound USB Audio driver correctly.
|?||How do I install firmware?|
|To install firmware, follow these steps:
|?||When I try run the software installer on my Windows PC, I get a message saying 'Not a valid Win32 application'|
|Windows Vista or later is required.
This message indicates that you are running an older version of Windows, such as Windows XP.
|?||I’m unable to install on a Mac - the Mac says the package was downloaded from an unidentified developer.|
|Installing the Lyra, Titan, and Atlas Control Panel app and the Callia firmware updater.|
This is a Mac pkg or mpkg file, and under modern MacOS there is a possibility that Security settings may disallow you from installing software that isn't downloaded from the Apple app store.
In System Preferences / Security & Privacy, the General page has a setting called
"Allow apps downloaded from:"
The options in OSX up to Sierra were:-
App store and identified developers
However in Sierra 10.12.0 and higher, the "Anywhere" option has been removed. Running the "USB Audio Control app" installer package may initially fail under Sierra with a message like this:-
It may fail depending on that setting under an earlier MacOS too.
However when this happens in Sierra, if you go into the Security & Privacy Preferences, it will now show an option to run this particular installer package:-
and pressing the “Open anyway” button will run the installer unimpeded.
|?||How do I use ASIO drivers on Windows with Pro Tools?|
|Pro Tools requires that you use a power-of-two buffer size: 64, 128, 256, 512, 1024.
You need to set this buffer size in the USB Audio control app before you open Pro Tools.
Once you have done this, you should find that Pro Tools allows you to select Prism Sound USB Audio Class 2.0 as the audio device.
|?||Can I connect multiple boxes to my PC?|
Operating over USB under ASIO and WDM – No. The ASIO and WDM Audio drivers connect to the first box that the PC detects on the USB bus.
Multiple Titan and Atlas units can be connected to a Pro Tools | HDX card, Pro Tools | HD Native PCIe card or Pro Tools | HD Native Thunderbolt unit, and they will to operate in sample sync in Pro Tools | HD software. These interface devices come with ASIO drivers that can be used with software other than Pro Tools | HD.
|?||Can I connect multiple boxes to my Mac?|
You will need to create an aggregate device
For best results, ensure that you set one box as the clock master and the others as slaves. On the USB Audio control app, ensure that the Slave boxes are sync'd to the master with a WCK or DI connection.
If you do this, you should uncheck the 'Drift Correction' box.
Multiple Titan and Atlas units can also be connected to a Pro Tools | HDX card, Pro Tools | HD Native PCIe card or Pro Tools | HD Native Thunderbolt unit, and they will to operate in sample sync in Pro Tools | HD software. These interface devices work as Core Audio devices that can be used with software other than Pro Tools | HD.
|?||How do I set the buffer sizes?|
|Starting with driver version 1.05, there are two settings for the buffers. These relate to Windows operation only; you don't need to set buffers on a Mac as it's handled automatically. The "base" setting is for the USB connection and relates to both WDM and ASIO operation. The ASIO buffer settings have no effect on the WDM drivers. The default settings are designed to be safe with any modern PC and will only need adjusting if you want to reduce the latency in the system or if you are experiencing glitches. In either case, please see the technical note on buffer settings in Windows USB drivers for a more detailed discussion.
|Trouble Shooting FAQs|
|?||Why are there only 4 ADAT channels at 96kHz?|
|The ADAT format allows 8 channels of digital audio on a single optical connector, but only at sample rates up to 48kHz.
At 88.2kHz and 96kHz, the S/MUX format must be used instead. S/MUX is a way of squeezing higher frequency signals into an ADAT carrier. Twice as many samples are transmitted for each channel, so there can only be half as many channels.
|?||How do I measure the round-trip latency?|
|It is very easy to measure the round-trip latency of your audio interface using a DAW and a digital cable
Use these steps:
You can verify the delay with a null test. Invert the recorded track & mix with the original; the samples will cancel out exactly.
|?||How can I eliminate audio glitches and reduce latency on my Windows PC?|
|Your CPU needs a certain amount of time to process audio samples. We recommend that you optimise your computer for audio processing and disable any unnecessary applications.
