First, make sure that your audio interface is set to ASIO mode:
- Press P to open the Preferences window
- Select “Devices” from the left column (under Audio in the left column)
- Uncheck anything in the Input Drivers and Output Drivers lists
- Click “Playback and Recording” from the left column
- Set the Driver Mode to ASIO
- Select “Devices” from the left column again
- Check all of the US-16x08 inputs and outputs that you want to use
If you still have problems, change the Buffer Size in the US-16x08 control panel:
- Open the US-16x08 control panel
- Click the Interface tab
- Change the Buffer Size to a higher setting
According to Apple, OS X 10.9.5 includes heightened security measures that will also be part of OS X 10.10. These security measures will affect some TASCAM audio interfaces, so users are advised to be aware, and hold off on updating until further information is available
These products use Apple's built in CoreAudio driver. The Settings Panel installer is fully compliant with Apple's latest security measures.
- US-2x2
- US-4x4
The latest drivers are compliant, but testing is ongoing for these products:
- US-322
- US-366
- US-1200
- UH-7000
The OS X 10.9 public beta drivers can continue to be used for these interfaces:
- US-122mkII
- US-144mkII
- US-200
- US-600
- US-1641
- US-1800
- US-2000
Cannot be used with the current driver (public or beta):
- IF-FW/DMmkII: Development is on-going and a version that is compliant with the new security measures will be made available as soon as possible. Please keep your system at 10.9.4 or earlier if you wish to continue to use the IF-FW/DMmkII.
- TASCAM Mixer Companion: Gatekeeper Security must be set to "allow all" for TMCompanion to be installed. It can be reverted to higher security settings after installation.
- Other audio interface products not mentioned are no longer supported.
Windows allows the processor to throttle to half speed when the computer is idle. However, this can affect the performance of DAW recording software. TASCAM recommends that this function be disabled, especially when using a multi-channel interface such as the US-16x08.
To Change the Power Management settings in Windows:
- Open the Control Panel.
- In Windows 8 this is under “Settings” in the right pane of the desktop
- In Windows 7 and earlier this is in your Start menu
- Open the Power Options control panel by double-clicking it
- Click “Show Additional Plans”
- Click on “High Performance” in the Power Options
Open the US-2x2 / US-4x4 Settings Panel and switch "Line Outputs 1-2" to Monitor. If this is set to "Computer 1-2," the Monitor Balance knob won't do anything.
Depending on the usage environment, reboot the interface by turning the power off/on again, or disconnect and reconnect the USB cable.
