Mobile Solutions’ Phase Test Instruments are the “secret weapon” for today’s installation professional to ensure that ALL speakers in the audio system are acoustically working together in absolute phase. Both the PT-9 and PT-9A feature a built-in microphone and come with a test CD that includes in phase and out of phase pulses (in addition to 11 other useful test tracks). The PT-9A adds a built in pulse generator for both speaker level low level connections directly to a component (speaker, amplifi er, signal processor, etc.). Both units come with a protective carrying case and the PT-9A (shown) also comes with test leads. You’ll wonder how you ever tuned audio systems without one of these. If you would like to see how either phase test instrument is used in their entirety.
