[. . . ] BTR2000 Users manual Version 1. 0 April 2005 RACKTUNER DEUTSCH RACKTUNER BTR2000 IMPORTANT SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosurevoltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] Position your instrument as close as possible to the BTR2000. Make certain that there is as little noise as possible to disrupt the tuning process. 4. 1. 3 Tuning with a reference tone + 1. The BTR2000 can generate and output notes. You can then tune your instrument by ear without an optical display. If your instrument is plugged into INPUT 1, the reference tone is output only through the SOUND output connector; if it is plugged into the INPUT 2 connector and there is nothing plugged into the SOUND output, the reference pitch is played through the MAIN output together with the instrument signal. Select the tuner mode you wish to use (see chapter 4. 2). The BTR2000 can only recognize certain pitches depending on the tuner mode selected. Calibrate the reference tone and set the transposition if desired (see chapter 4. 3 / 4. 4). Briefly press the SOUND/METRONOME button. The sound mode is activated and the SOUND LED above the SOUND/METRONOME flashes. The display shows the volume level currently set (1, 2, . . . The unit emits the lowest pitch available in this mode or the last pitch set in the tuner (even if it is not available in the currently selected tuner mode) through the SOUND and/or MAIN connector on the back panel of the BTR2000. The volume of the reference tone can be set with the wheel. After briefly pressing the TRANSPOSE/REF button you can turn the wheel to change the reference tone emitted depending on the selected tuner mode. During this adjustment the TRANSP and SOUND LEDs are illuminated. After a short time or after the TRANSPOSE/REF button is pressed again, the unit returns to sound mode and the wheel can again be used to control the volume. Tune each string of your instrument to an appropriate reference tone. + 2. 8. When you press the MUTE button, the MAIN output (instrument sound and possibly the reference tone as well) is muted; the SOUND output is not affected. To exit sound mode, briefly press the SOUND/METRONOME button again. The SOUND LED will go out and the tone will no longer be emitted. 4. 2 Selecting tuner mode The open strings on each instrument (e. g. guitar, bass, ukulele) are tuned differently. It is also possible to deliberately tune an instrument such as a guitar to a so-called open tuning to make it easier to play in a particular key. [. . . ] Be certain to leave an additional 10 cm free in the back for the connectors. For installation in a rack, M6 machine screws and nuts should be used. Ensure a sufficient air supply and to not place your BTR2000 on an end, for example, to prevent the unit from overheating. 8. 2 Audio inputs and outputs All audio inputs and outputs on the BEHRINGER BTR2000 are laid out as mono TS connectors. Fig. 8. 1: 1/4" TS connector 8. 3 Footswitch wiring If a double footswitch is plugged into the SELECT connector on the back of the BTR2000, the MUTE function is transmitted on the ring and SELECT is transmitted on the tip.
