Turns your PC into the most complete easy-to-use electrical and acoustical measurement system…

CLIOWin Lite is the entry-level version of the software at an unbelievably low price! With the CLIOWin Lite system you get the new 6.5 version of the CLIOWin Lite software, the PCI 4281 PC board and the SC-01 Signal Conditioner.

Before you start measuring you should read the book "Testing Loudspeakers" by Joe D'Appolito.
