SSL USB Control Panel (Windows Only)
If you're working on Windows and have installed the USB Audio Driver required to make the unit operational, you will have noticed that
as part of the installation the SSL USB Control Panel will be installed onto your computer.
This Control Panel will report details such as what Sample Rate and Buffer Size your SSL 18 is running at. Please note that both
Sample Rate and Buffer size will be taken control of by your DAW when it is opened.
The SSL USB Control also allows access to Clock source settings, optional between the internal clock, ADAT (Optical 1) or S/PDIF
(Coaxial), also assignable within the 360 Mixer Page.
The Control Panel is also where you can assign your SSL 18 to an ASIO Device; allowing multiple ASIO applications working with
multiple SSL USB devices to be used on a single system or in a multi client environment.
Please refer to this article for a detailed explanation of linking your interface to one of the 4 ASIO driver slots to SSL 18.
Safe Mode
One aspect you can control from the SSL USB Control Panel is the tickbox for Safe Mode on the 'Buffer Settings' tab. Safe mode
defaults to ticked but can be unticked. Unticking Safe Mode will reduce the overall Output Latency of the device, which may be useful if
you are looking to achieve the lowest possible roundtrip latency in your recording. However, unticking this may cause unexpected
audio clicks/pops if your system is under strain.
