Instantaneous visual indication of how much the pitch of your instrument differs from the precise target pitch you are trying to tune. Real-time display of intonation and harmonic content to improve performance and listening skills while playing. Key features include mutable throughputs for in-line (yet silent) tuning during performances, automatic image clarity and contrast control which internally compensate for optimal viewing over a wide range of source pitch and volume, improved clarity for upper and lower register notes (our +2/-1 display feature shifts the strobe patterns into more visible middle ranges so that bass note patterns can be displayed two octaves higher and treble note patterns can be displayed one octave lower in strobe display), and easy transposition (strobe patterns appear at the correct note for Bb, F, and Eb instruments). The AutoStrobe 490 is a truly stroboscopic mechanical tuner capable of fundamental and overtone display. Other companies may boast of their strobe tuner capabilities, but buyer beware! Enjoy hands-free note selection for fast, accurate tuning of instruments. Only Peterson could bring you the kind of real-time intonation critical enough for ear training use. The Peterson AutoStrobe 490 is agreed by music students, technicians, and professionals to be the standard by which all tuners are measured. External Input And Through Output With Mute - For In-Line, Silent Tuning During Performances.Enhanced Clarity For Upper And Lower Register Notes - +2/-1 Display Feature Shifts The Strobe Patterns Into More Visible Middle Ranges - Bass Note Patterns Can Be Displayed Two Octaves Higher And Treble Note Patterns Can Be Displayed One Octave Lower In Strobe Display.Automatic Image Clarity And Contrast Control - Internal Compensation For Optimal Viewing Over A Wide Range Of Source Pitch And Volume.ONLY Peterson! The R490 Rackmount comes with Rack Mounts and Jacks on Front and Back FEATURES External Input And Through Output With Mute - For In-Line, Silent Tuning During Performances.The AutoStrobe 490 brings accuracy that only the speed of light could measure.

And as usual, only a Peterson can respond at the speed of light to display relative tuning information extracted from any audio source down to 0.1 of a cent (1/1000 of a semitone) accuracy! Finally, utilize automatic (hands-free) note selection for fast tune ups of instruments. It combines both input instrument tone and audio standard reference tone at the output for simultaneous visual and audible tuning along with exceptional intonation training! The 590’s key features (automatic note tracking and audio tone generation capabilities) make it a favorite in the classroom, at the factory, or backstage. The R590 comes with Rack Mounts and Jacks on Front and BackThe AutoStrobe 590 is THE preeminent mechanical strobe tuner for tone generation and metronome facilities. It combines input audio for contrast against on-board reference pitches. The AutoStrobe 590 is a mechanical tuner that comes complete with built-in tone generation and a metronome via headphones or internal speaker output.
