Stage Tuner ST-02, format rack 19 poucesThe RockBoard StageTuner ST-02 offers all the features that musicians want in a chromatic rack tuner. The large, bright, but not blinding LED display offers an easy-to-read surface that is clearly visible even from a distance of several meters. The true bypass doesn't affect the sound of the connected instrument and with two inputs (one on the front and one on the back), the StageTuner ST-02 can be flexibly integrated into any rack. The calibration range frequency of the ST-02 can be set in 1 Hz steps from 432 to 445 Hz and the large detection range from B-1 (15.44 Hz) to C8 (4,186.0 Hz) also covers extended range instruments or lower tunings easily. In addition to the standard mode, in which the arrows on the left and right in the display show the tuning direction, the StageTuner offers a strobe mode. Besides the standard installation in a 19'' rack, the StageTuner can be mounted quickly and easily on a RockBoard pedalboard with the RockBoard QuickMounts TYPE M (available separately). All of this makes the StageTuner ST -02 a perfect choice for the stage, studios, rehearsal rooms and basically any other conceivable application. chromatic 19'' rack tuner for electrical instrumentsdetection range: B-1 (15.44 Hz) - C8 (4,186.0 Hz), sine wavetwo selectable tuning modes (Standard, Strobe)precision: +/- 1 centcalibration range: 432 - 445 Hz (1 Hz steps)LED displayincl. rack-mount adapters for easy mounting in 19'' racksM4 threaded sockets on the back of the tuner to attach RockBoard QuickMounts TYPE M (sold separately) for quick and easy mounting on RockBoard pedalboardstrue bypassinput: 2x 6.3 mm / 1/4'' mono jacksoutput: 1x 6.3 mm / 1/4'' mono jackpower supply via 9V DC adapter, 2.1 x 5.5 mm barrel plug, polarity (-) center (included in the delivery)current draw: max. 250 mA2x rack-mount adapter and 8x M4 screws for rack adapter or QuickMount (sold separately) included in the deliverydimensions (WxDxH): 395 x 63 x 44.45 mm / 15 35/64'' x 2 31/64'' x 1 3/4'' (without rack-mount adapters)weight: 730 g / 1.6 lbs (without rack-mount adapters)
