Operation

The supplied adapter cable allows you to take the left

channel from a 1/8" mini stereo headphone or mono

microphone jack and attach it to the RCA jacks on THAT-2.

Handset Type Switch

The three position switch on the front of THAT-2 selects the

type of microphone that is in the handset of your telephone.

When you push the Line In button in, THAT-2 replaces the

handset microphone signal with a circuit that must match

the characteristics of the handset microphone.

The Handset Type switch can cover the main three

microphone types, but keep in mind that there is no

industry standard for microphone types or characteristics

and therefore we cannot guarantee a perfect match with

every telephone. There is no way to tell which type of mic is

in your telephone handset. Simply use the position that

sounds best without clipping or signal break-up.
