Can I use any headset with the AWS-100? - Yes, ANC or NC.

Which models of the IBM ThinkPad need the T-100? - Older models like the 760 E, ED, XD with the metal ring around the mic input. Newer models like the A20 and T21 series have adopted the standard PC convention so no T100 adapter is needed. However just as on the PC, ANC products must use the included "Converter Plug" (P-100 SoundBlaster Adapter).

Is a ThinkPad adapter only needed if the mic porthole has silver around it? - Yes, the units with a metal ring combine the mic input and line input into a single jack. Either a an APS-100 or a T-100 are required to power the microphone (NC or ANC).

Would the APS-100 work in any case or just if there is no silver around the mic porthole? - The APS-100 will work with ANC products in any case.

If I switch the toggle back and forth should my headset be turning off and on or does the headset always stay on? - The headset always stays on. The volume adjustment is for the headset only.

What is this disk that is included with the MC-100? - AudioCommander is included with some units. However, it is not needed for operation of the MC-100. Check here for the latest version of AudioCommander.

What is the signal adapter used for? - The signal adapter is an attenuator for the microphone input, and will reduce the signal passing through it. The signal adapter should not be used unless the microphone input level is too high even with the microphone volume all the way down. It should not be used on the speaker output lines as it will significantly lower your speaker volume.

Why is my speaker volume reduced? - The signal adapter is reducing your signal. Remove it. It is for the microphone input only.

When do I need the P-100? - The P-100 is needed for ANC products only. It is included in the box with all ANC products. ANC products must use this product with all new PC's.

When do I need a TRS1 adapter? - The TRS1 adapter is required when using Andrea ANC products with the Stereo USB Adapter Model USBD-2A. Connect it in-line with the mic plug of the ANC product. The TRS1 adapter also can be used instead of the P-100 adapter on PC99 computers.
