Only Peterson strobe tuners respond at the speed of light to display relative tuning of any audio source to 0.1 of a cent (1/1000 of a semitone) accuracy! In addition to the visual strobe indication, the Autostrobe 590 can function as an audio tuner by means of an Audio Out section, which combines input sound with reference-pitch tones into headphones or an internal speaker.
As with all the new AutoStrobe models, the Model 590 allows students, technicians, and musicians at all levels to utilize automatic (hands-free) note selection for fast, accurate tuning of instruments. This feature also permits real-time display of intonation and, combined with the Audio Out function, provides a great way to improve performance and listening skills while playing.
The peterson AutoStrobe 590 combines the best from over 40 years of strobe tuner technology with the latest advances in automatic note detection, image stability/clarity, and alternate temperament capabilities. Peterson has integrated the classic eight-octave strobe disc tuning system with precision digital microprocessor and motor control technologies to provide a versatile tuner with unsurpassed accuracy and features.
In addition, when not being used as an instrument tuner, the Model 590 functions as a programmable audio/visual metronome. This instrument is designed for simple "user-friendly" operation with little need to "press buttons" once the initial desired settings have been entered. It is the best choice for music educators, musicians, manufacturers, and for any application where an accurate and versatile tuner is required.
