Philips HTS3357 Home Cinema System - Audio Out

[StormyK]

I recently purchased a Philips HTS3357 home cinema system which i am very happy with. However, I am trying to connect some wireless headphones so that I can play the radio/DVD through the amp whilst listening in another room. I still want to be able to use the TV (via it's own sound) whilst using the radio output from the amp. However, there doesn't appear to be any audio out connections. I can get DVD output from the unit using a Scart with an audio out connection. However, this doesn't work with the radio (my main need) as it doesn't output via SCART. How can I create a suitable audio out or connect the wireless headphones in? Is there a device to attach to the wireless transmitter connection on the back which will give me an audio out? It has the following connections: SCART; Audio in; CVBS Video OUt, S-Video; Wireless transmitter; Component Video; Co-ax digital in; HDMI

Any help would be gratefully received
