It may happen, however, that a note is displayed as “A” but is actually slightly out of tune. This is shown by at least one of the four LEDs at the foot of the display lighting up. In certain cases even two of the LEDs may light up, which indicates that the pitch of the note played lies between the pitches represented by the two LEDs. When the circular tuner LED in the middle lights up, this means the note played is in tune.
7.2 Setting reference pitch “A”
To give you maximum freedom for tuning your guitar, you can change the preset reference pitch “A”. For clarity’s sake, let’s look at this in more detail.
The so-called concert pitch “A” has been raised steadily over time. For example, the tuning forks used by Bach, Händel or Mozart were 415, 420 or 421 Hz (oscillations per second). Today’s orchestras tune to “A” at 444 Hz, and the Berlin Philharmonic Orchestra lead the field with their own concert pitch “A” at 447 Hz.
The reference “A” on your V-AMPIRE/V-AMP PRO/V-AMP 2 has been factory-programmed at 440 Hz. If you are going to play with a big orchestra tuning their instruments to a reference pitch of 444 Hz, you will need a function that allows you to change your reference pitch. To activate this function, switch on the tuner by pressing the TUNER button and switch to EDIT mode by pressing the two arrow keys simultaneously. The display will show “40”, which means 440 Hz. Use the arrow keys to raise or lower the reference pitch by up to 15 Hz. The display always shows the last two digits as the first digit is always 4. For example, if you start with a reference pitch of 440 Hz and press the right-hand arrow three times, the display will read 43, i.e. 443 Hz. To quit EDIT mode, press either the TUNER or the TAP button. Any changes will be stored automatically. The tones for the other strings on your guitar will automatically be adjusted to the new reference pitch.
8.INSTALLATION
8.1Mains voltage
Before you connect the unit to the mains, please make sure that the voltage setting on the unit matches the local voltage! The fuse holder at the AC power connector has 3 triangular markings (V-AMPIRE/V-AMP PRO only). Two of these three triangles are aligned with one another. The unit is set to the voltage shown next to these markings and can be switched over by turning the fuse holder by 180°. IMPORTANT: This does not apply to export models designed exclusively for 120 V operation!
+If you set the unit to a different mains voltage, be sure to use a fuse of the correct type and rating. Please refer to chapter 10 “SPECIFICATIONS” for details.
+Blown fuses must be replaced by fuses of the same type and rating! Please refer to chapter 10 “SPECIFICATIONS” for details.
V-AMPIRE/V-AMP PRO: The mains connection is made using the enclosed power cord and a standard IEC receptacle. It meets all of the international safety certification requirements. V-AMP 2: the mains connection is made using the enclosed power supply.
+Please make sure that all units have a proper ground connection. For your own safety, never remove or disable the ground conductor from the unit or of the AC power cord. The unit shall always be connected to the mains socket outlet with a protective earthing connection.
