A complete loudspeaker and audio test system is now available from Stephen Court - creator of Sound Check - one of the world's best selling test CDs. In the form of plug-in hardware, a CD-ROM for Windows and calibrated measurement mic, Speaker Check uses CLIO MLS technology which allows accurate measurements in ordinary room acoustics. The system converts a PC into a Pen Recorder and printer, Real Time Spectrum Analyser, Dual Channel oscilloscope and millivolt meter. It allows the measurement of frequency response, impedance curves, distortion v frequency, impulse response, phase response and a host of other useful speaker and audio system measurements.
