Sabine always brings you the industry's most innovative and precise tuners, and now they've got 2 new professional rack-mount tuners. The RT-7000 Series Rack Tuners are packed with the features you've been asking for in a rack tuner.
Features
Swoop LED Display: Gives you the best visual cue for easy tuning, especially from a distance. It works like a bar graph of your pitch, sweeping up for sharp and down for flat.
Bright & Easy to Read: Huge note indicator is visible from across the stage, even if you're wearing shades!
Dual Tuning Modes: Standard Mode gives you a bar graph reading of your pitch. Strobe Mode shows moving sweep of pitch. Both are more accurate than conventional needle-style LED displays.
Two independent channels: Select on front panel or with footswitch (not included).
SmartSwitch A/B circuit: The RT-7100 senses your input/output configuration and automatically adjusts the A/B switch to conform to your setup. Need two guitars routed to the same amp? Or one guitar split to 2 amps? No problem - just plug 'em in and you're ready to go!
Flat Tune: Set the tuner to any of 4 different flat tunings: 1/2, 1, 1-1/2, or 2 steps below standard pitch. Play and tune your guitar normally but at a lower overall pitch!
Calibration: Change the overall calibration of the tuner from 435 to 445 Hz
Mute: Mute your instrument for silent tuning - select on front panel or with foot switch
Built-in Mic: Tunes almost any acoustic instrument
Dual Jacks: Front and back panel input/output jacks
