Circle Surround® TDM Pro

Frequently Asked Questions

Can I apply additional dynamics or effects to the Lt/Rt output (post encoding)?
If it is decided to do processing on the Lt/Rt, the channels must be treated equally and their level and phase relationships must remain intact. In general, you will want to avoid additional processing on the two-channel output because this can tamper with the encoded information.

The Lt/Rt output seems to be out of phase, is there something I can do to correct this?
The phase output of the Lt/Rt signal is part of what drives the ability to decode to surround. Do not attempt to correct the phase relationship here. Concentrate on maintaining in-phase relationships between discrete channels at the input to get the best encoded signal.

The plug-in decoder is showing output, but I am not seeing or hearing anything on the destination bus.
Make sure that the routing is correct.

I have purchased the plug-in and received a serial number, but the License is not on my iLok account?
You need to visit the page http://www.srswebauth.com/iLokAuto.aspx to let us know your iLok account user name. With the serial number, your iLok account will be loaded with the license for the TDM plug-ins. Please be patient. This can only be done once per valid, issued serial number.
