14 BASS V-AMP / BASS V-AMP PRO User Manual 7.2 Setting up the "a" reference tone 6.3.3 Special effects VCF+FLANGER: The combination of filter and flanger effect. VOICE BOX: This vocal simulation fades between various vowels (a/e, a/i, a/o etc.) by using a LFO (Low-Frequency Oscillator). You can control this effect via a MIDI foot controller. ULTRABASS: A very low bass sound that lies an entire octave beneath the lowest bass frequency present in the mix is currently very popular. However, this sound can often only be created at the studio because most bass amplifiers have no subharmonic function. The ULTRABASS processor, which has also found home in various BEHRINGER bass amps, makes creating this effect a no-brainer. You will be amazed how ultra-low the sounds created with the ULTRABASS function are. 6.3.4 Virtual analog bass synth SYNTH: This effect gives you a rad three-voice synthie bass and has many parameters that are pre-configured in 9 variants and can be selected via TAP and EFFECT. The TAP key can be used to control the envelope (ADSR) of the synthie sounds (short tap = short tone, slow tapping = long tone). Additionally, there is an "intelligent" envelope follower based on key and interval, whereas the VCO 1 (Voltage Controlled Oscillator) is set up for specific intervals, and the BASS V-AMP/BASS V-AMP PRO produces bass overtones that match the particular key. The EFFECTS control regulates the ratio between the bass synthie and the bass signal with all amp and cabinet combinations. MIDI SYNTH: The absolute highlight of your BASS V-AMP/BASS V-AMP PRO is our MIDI SYNTH: With 40 parameters (already described), it offers you the best possible sound. You get a virtual analog MIDI synthesizer equipped with powerful features. It is ideal for hardware and software sequencers, keyboards and for live applications. By using the EFFECTS control, you can mix the completely modelled instrument signal (EFFECT min. = modelled instrument signal only, EFFECT max. = bass synth only). We equipped the MIDI synthesizer with a complete reverb section as an additional feature. Of course, you can access this section via MIDI. To put complete freedom at your disposal when tuning your instrument, you have the option to change the preset of the reference tone "a". Here is a quick intro to the subject. The so-called "chamber tone a" has been continually revised upwards ever since it was first measured: tuning forks of Bach, Handel or Mozart were at 415, 420 or 421 Hz (vibrations pro second). Nowadays, orchestra set the "a" with 444 Hz, and the Berlin Philcharmonic wishes to stay ahead still: their "chamber tone a" lies at a full 447 Hz. The reference tone "a" of the BASS V-AMP/BASS V-AMP PRO is programmed at 440 Hz. Let's say, you want to work with a big orchestra that works with the chamber tone "a" set to 444 Hz. To activate the function that changes the chamber tone, do the following: activate the tuner by pressing the TUNER key and immediately switch over into the EDIT mode by simultaneous pressing both arrow keys. "40" appers in the display, which responds to 440 Hz. By pressing the arrow keys, you can adjust the "a" reference tone up or down in 1 Hz increments for a maximum of 15 Hz. The last two digits of the frequency value are always shown in the display, since the first digit is always a 4. For example, when you start with the 440 Hz basic tone, and then press the right arrow key four times, the display shows 44, which corresponds to a frequency of 444 Hz. To quit the EDIT mode, press the TUNER key. Your changes are automatically stored. Ideal tones for the remaining strings are automatically set up using the newly adjusted frequency as a reference. 8. Installation 8.1 Rack mounting (BASS V-AMP PRO) Your BEHRINGER BASS V-AMP PRO needs two rack units to be installed in a 19-inch rack. Please keep in mind that you need an extra 10 cm depth for accessing the cables running into the back. Assure that appropriate ventilation is provided, and never position your BASS V-AMP PRO on top of an amp, for example, to avoid the danger of overheating the unit. 8.2 Voltage (BASS V-AMP PRO) ROTARY CAB.: A simulation of a classic organ effect that is normally achieved with a terribly heavy casing and slowly or quickly rotating speakers. The physical principle of the Doppler effect is used to modulate the signal. 7. Tuner The integrated tuner is activated by pressing the TUNER key. 7.1 Tuning instruments The chromatic tuner automatically recognizes the frequencies of all the standard bass notes. When you connect your instrument to the BASS V-AMP/BASS V-AMP PRO and strike a string, the tuner tries to recognize the tone and shows it in the display. Because the tuner functions chromatically, it can also recognize semitones. These are shown in the display with a "b" accompanying the value. However, it may be the case that that a played note (shown in the display as for example "a") slightly deviates from the ideal tone. This will be indicated by lighting up at least one of the four arrow LEDs at the lower edge of the display. When the note played lies between the deviations shown by means of the individual LEDs, two LEDs may light up. If the circular middle tuner LED lights up, the played note is identical to the note shown in the display. Before you connect your BASS V-AMP PRO to the mains, please check carefully if your unit is set to the correct voltage! The fuse mount near the power cord connector has three triangular markings. Two of these three triangles are facing opposite one another. Your BASS V-AMP PRO is set up for the voltage indicated near these markings, and can be altered by turning the fuse mount by 180 degrees. ATTENTION: This does not apply to export models built for 120 V, for example! ◊ If you use the unit with a different voltage, you must change the fuses accordingly. The correct value of the fuses needed can be found in the chapter "Specifications." ◊ Faulty fuses must be replaced with fuses of appropriate rating without exception! The correct value of the fuses needed can be found in the chapter "Specifications." Power is delivered via the cable that was delivered with the unit. All requiered safety precautions have been adhered to. ◊ Please make sure that the unit is grounded at all times. For your own protection, you should never tamper with the grounding of the cable or the unit itself.
