5 BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual

1. Introduction

Congratulations! By purchasing the BASS V-AMP/BASS V-AMP PRO, you have selected a modern virtual bass amplier that sets new standards in the world of bass preamps. Our primary goal was to achieve the classic sound of bass amps by using “Physical Modeling” and implementing the newest DSP eects. Followingthe tremendous success of our V-AMP and its successor V-AMP 2, withthe BASS V-AMP/BASS V-AMP PRO we are nally able to oer bass players the same diversity of sound.

However, we went a step further and expanded the concept to include items of interest to keyboarders and electric/acoustic guitar players. Those who have already used the V-AMP or the V-AMP 2 will appreciate the BASS V-AMP/ BASS V-AMP PRO as a terric improvement.

We wanted to create two devices that would stir conversations in years to come: theBASS V-AMP/BASS V-AMP PRO is universally usable and oers authentic amp and even speaker sounds—all this without having to transport heavy equipment! Additionally, the most modern multi-eects processors assure unprecedented tonal freedom. In short, the BASS V-AMP/BASS V-AMP PRO gives you a “sound machine” sporting the hottest features of the day.

Future EPROM updates will make sure your BASS V-AMP/BASS V-AMP PRO always has the latest software and features.

BEHRINGER is a company in the eld of professional audio studio technology. We have been successfully developing products for live and studio applications for years. Among those are microphones and 19" gear of all kinds (compressors,enhancers, noise gates, tube processors, headphone ampliers, digital eects units etc.), monitoring and PA loudspeakers as well as professional live and recording mixing consoles. Our entire technical know-how has gone into creating your BASS V-AMP/BASS V-AMP PRO.

To top it all, we worked together with professional bass players, whose sound suggestions led to the creation of original artist presets. Just a single glance at the separate preset sheet will be enough to completely amaze you.

Flexibility is what matters most in the music industry. Bass players should be able to oer a wide array of dierent sounds, and should also be able to temporarily adjust to the demands of home recording, studio and live applications. Bulky amp combinations are out of sync with today’s times precisely because of this reason. The BASS V-AMP/BASS V-AMP PRO oers you a maximum set of features in a compact unit that can be gured out in no time.

But enough talking: Nothing will convince you more than the shear joy of what you will hear and feel the rst time you play with your BASS V-AMP/BASSV-AMP PRO. You will experience a latest-generation vir tual bass amplier with fascinating features:

• Extreme sound variety and exible output routing options for bass players

• Multi eects, amp and loudspeaker simulations for keyboard players

• Remarkably clean, high-gain sound and acoustic simulations for

electricguitars

• Sound enhancer for acoustic guitar sound pickup

• Uncompromising loop/sampler function, super-phat analog bass synth and

the best distor tion pedal simulations.

2. Control Elements

An illustration of all control elements is located on the separate sheet included with this user’s manual. The controls on both devices are numbered the same way. Howthe two versions dier is clearly marked by using the designations “BASSV-AMP only” or “BASS V-AMP PRO only.” Connections on both versions are covered in a separate chapter in this user’s manual.

2.1 Unit top/front side

(1) Turn your BASS V-AMP PRO on using the POWER switch. The POWER switch

should always be in the “O“ position (depressed) whenever you rst connect the unit to the mains.

◊ Please note: Merely switching the unit off does not mean that it is fully

disconnected from the mains (BASS V-AMP PRO only). When not using the unit for prolonged periods of time, please unplug the unit’s power cord from the wall.

(2) The GAIN control determines level and saturation charac-teristics of the

ampsimulation.

(3) The VOLUME control governs the volume of the selected preset.

(4) The BASS control on the EQ section lowers or elevates bass frequencies.

6 BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual

◊ When the TAP button (11) is depressed, the BASS control changes its

function to DEEP control, which inﬂuences the sound in the lower frequency segment.

(5) The MID control lowers or elevates the mid frequencies.

◊ MID-SHIFT/SHAPE: When you select an amp simulation using the AMPS

control, press the TAP button to use the MID control to adjust the mid frequency range (SHIFT). With amp simulations that don’t originally have such a function, pressing the TAP button as described above activates the BEHRINGER SHAPE filter instead.

(6) The TREBLE control regulates the upper frequency range of an

activatedpreset.

◊ Pressing the TAP button (11) changes the function of the TREBLE control

to PRESENCE control. This enables lowering/elevating upper frequency range values of a ﬁlter selected for the amp model active at this time. This ﬁlter simulates the frequency-dependent coupling of tube amps.

◊ Please pay attention to the special functions (described under ( 8 ) )

of the following points: ( 2 ) , ( 3 ) and ( 5 ) !

(7) The AMPS control lets you select one of the 32 amp simulations. 16 LEDs

surround this control, whereby 1 LED is assigned to 2 amp types. You select one of the rst 16 amp types (white lettering) by simply turning the control.

To select the next 16 amps (17 - 32, grey lettering), keep the TAP button pressed as you turn the AMPS control.

◊ The “17 - 32” LED in the lower left corner of the DISPLAY lights up when

one of the amp simulations numbered 17 - 32 is selected.

Additionally, you have the option to activate a PREAMP BYPASS via the TUNER (9) and TAP (11) key combi-nation. When PREAMP BYPASS feature is activated, no AMPS control LED is on. To disengage the PREAMP BYPASS feature, either select an amp model of your choice or press the TUNER and TAP keys again.

(8) These ve keys are used (among other things) for preset selec tion of the

presets bank shown in the display.

In EDIT mode (activated by simultaneously pressing the arrow keys described under (10) ), the function of individual keys is indicated by the print located directly above the respective button:

• A: Activates the MIDI function. By utilizing the arrow keys, the MIDI channel

used for sending and receiving (1 to 16) can be set up.

After selecting a MIDI function via the A key, pressing the TAP key relays the MIDI out connector to MIDI Thru. When in this mode, the unit sends no MIDI information of its own; instead, it merely passes on the data received at theMIDI In.

• B: Switches the DRIVE function on and o. When DRIVE is enabled, the

controls (2) , (3) and (5) take up the following functions:

• GAIN regulates the distortion degree (“DRIVE”).

• The VOLUME control regulates an additional volume

control (“BOOST”).

• Use the MID control like the tone control on a simulated distortion

pedal (“TONE” ).

Well-known oor eec ts units are simulated with these setups.

◊ When the DRIVE function is activated, turning the EFFECTS MIX controls

lets you also set up the Wah- Wah. The LEDs surrounding the EFFECTS MIX control show the position of the pedal. When the LED is not on, the Wah-Wah is inactive.

◊ When the Auto Wah/P-Funk’n is activated, the Wah- Wah cannot

be used.

• C: This key activates the CABINETS mode. Use the arrow keys to select a type

of loudspeaker or a combination of loudspeakers. You can also completely switch o the speaker simulation (“-”). Additional information is available in chapter 5.2.

• D: Activates the X-OVER function. Use the arrows to regulate the

cut-o frequency between high-pass and low-pass lter. This is done in 50gradients (please also see chapter 6.3).

• E: Activates the DENOISER function. You may change the threshold of

the expander by using the arrow keys. The EFFECTS control regulates the sensitivity of the noise reduction system, while pressing TAP changes the function of the EFFECTS control so that it regulates the frequency range of the noise reduction system (also see ch. 5.3).

◊ After preset editing, press the TUNER/EXIT button to quit

(the EDIT MODE LED dies out).

◊ DIGITAL OUT: The digital output on the BASS V-AMP PRO can be

configured by pressing buttons A and B simultaneously. The display shows “SP” for S/PDIF or “AE” for AES/EBU format. Alternating between the two formats is done by using the TAP key. The LEDs let you see the respective sample rate (internal synchronization and sampling rates of

44.1, 48 or 96 kHz or external wordclock synchronization; see table 2.1). To select the most appropriate sampling rate for the receiving unit, please use the arrow keys. Press the TUNER/EXIT key to quit.

◊ CONFIGURATION: By pressing the D and E keys simultaneously on your

BASS V-AMP PRO, you can select the global operating mode (keys B and D on your BASS V-AMP), so that an adjustment to diverse studio and live situations is possible (see chapter 3). Please press the TUNER/EXIT key to quit.

(9) The TUNER key engages the tuner. Additionally, you can exit the EDIT mode

by pressing this key (see chapter 7).

(10) Both arrow keys are used to select the next preset bank (BANK DOWN und

BANK UP). Keeping the keys pressed lets you quickly jump through the

preset banks. Pressing both arrow keys at the same time engages the EDIT mode. When you press one of the A - E buttons ( (8)) afterwards, each arrow key takes over an edit function.

(11) The TAP key has eight functions:

• “Tap”: Tap the TAP key in the rhythm of a tune, and the selected eect

adjusts automatically to the appropriate speed.

• “De ep”: By keeping the TAP key pressed, the BASS control assumes the

function of a DEEP control, so that it regulates the sound in the deep bass end of the spectrum.

• “Mid-Shift/Shape”: When an amp simulation is selected using the AMPS

control, keep the TAP key pressed and use the MID control to regulate the middle portion of the frequency range (SHIFT).

Our BEHRINGER SHAPE lter is automatically activated with amp simulations that do not have such a function (as described above) in the original.

• “Presence”: Keep the TAP key pressed to use the TREBLE control to regulate

PRESENCE in a particular amp simulation.

• “2nd parameter”: The second eect parameter (regulated by the EFFECTS

control) is accessed by keeping the TAP button pressed (see chapter 6).

• “Amp models 17 - 32”: Keep the TAP key pressed and select the desired

simulation by using the AMPS control.

• “MIDI Thru”: The MIDI Out connector can be set to MIDI Thru (see (8) A).

• “Compressor”: The compressor control regulates the attack time when the

TAP key is kept pressed (see (14) ).

7 BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual

(12) DISPLAY shows the selected eects bank and gives information about the

changes occurring while editing. When the tuner is enabled, the display shows the tuning of the connected instrument. When one of the amp simulations numbered 17 - 32 is selected, the LED located in the lower left corner of the DISPLAY lights up.

The display on the BASS V-AMP PRO gives additional information about the digital format and the sample rate of the unit, and indicates that the BASSV-AMP PRO should be synchronized to an external wordclock signal. Connec-ted input signals are displayed with the green SIGNAL LED; distortedsignals are marked with the red CLIP LED.

◊ In addition to the AUX LEVEL control on the BASS V-AMP, this is the

only non-programmable control of the BASS V-AMP/BASS V-AMP PRO. All additional controls are infinitely turnable, and their positions can be saved in a preset.

◊ The LED circles surrounding the VOLUME, BASS, MID, TREBLE, GAIN,

EFFECTS MIX and COMPRESSOR controls each have nine LEDs. Either one LED or two adjacent LEDs light up in each LED circle at any one time. This occurs when the control is in an in-between position. This way, a total of 17 positions can be displayed.

(17) The connector labeled INPUT is the ¼" TS jack input of the BASS V-AMP/

BASSV-AMP PRO, which is where an electric bass, an acoustic guitar, akeyboard etc. can be connected. Use a common 1/4” mono jack cable forthispurpose.

(18) The LINE IN switch regulates which signal source of the BASS V-AMP PRO

is processed. When the switch is not pressed, this refers to the the signal connected to the input connector (e.g. electric bass). When the switch is depressed, the line signal connected to the PRE DSP INSERT (LINE IN, (20) ) isrouted to the processor (par-ticularly useful for keyboards).

(19) You can connect standard headphones to the PHONES connec tor of your

BASS V-AMP/BASS V-AMP PRO.

◊ When headphones are connected to your BASS V-AMP/BASS V-AMP

PRO, studio mode 1 (S1) is automatically activated. If you opted not to select a loudspeaker type in your setup and then connect a set of headphones, your BASS V-AMP/BASS V-AMP PRO automatically selects a speaker simulation. This improves the subjective listening impression while using headphones. To look up which speaker simulation is paired to which amp, please see table 5.1. However, you can deactivate a simulation while listening to headphones by selecting “-” in CABINETS mode. Conversely, it is possible to freely select the global output configuration when a set of headphones is connected, so that you can for example check the effect various modes have on your sound.

(13) The EFFECTS control lets you selec t an eects preset or a combination of

several eects. This continuously turnable control is surrounded by a circle of 16 LEDs. Each eect has a corresponding LED.

(14) The COMPRESSOR control lets you compress or limit your sound. Whenyou

turn the COMPRESSOR control as far left as possible without triggering o a LED, the dynamic characteristics of the signal are not changed. Thecompressor on the BASS V-AMP/BASS V-AMP PRO controls two important functions:

• You set the compression sensitivity by turning the COMPRESSOR control.

Themore you turn the control, the more pronounced the compression. Whenthe last LED lights up while turning the control to the right, the eect acts as a limiter.

• Turning the COMPRESSOR control while keeping the TAP key pressed lets you

set the attack parameter of the com-pressor.

◊ More detailed information about how a compressor works can be found

in chapter 5.3.

(15) When an eect is selected using the EFFECTS control (13) , the proportion

with which this eect inuences the entire sound is regulated using theEFFECTS MIX control. As long as no LED lights up while turning the control leftwards, no eect is mixed in. This is also called an eect bypass, and mutes all eects accross the board.

◊ When the TAP key is kept pressed, a second effects parameter can be

regulated using the EFFECTS control (see tables 6.1 and 6.2).

(16) The MASTER control regulates the overall volume of your BASS V-AMP/

BASSV-AMP PRO.

(20) You can insert external eects into the serial insert loop featured on the

BASS V-AMP PRO. The SEND/LINE OUT connector is connec ted to the input of your eects unit for this purpose. The SEND/LINE OUT output is tapped into directly before the digital signal processor (PRE DSP). This connector is therefore ideal for recording “dry” signals (i.e. without the eects portion).

Please connect the RETURN/LINE IN connector with the output of your external eects processor or recorder.

◊ When using the serial insert loop, please make sure that your effects

processor is not set to 100% effect signal (“wet”), because otherwise the direct signal is missing.

◊ Pressing the LINE IN switch (22) routes the signal connected to the

RETURN/LINE IN connector to your BASS V-AMP PRO. This function may be of use when for example listening to a “dry” recording of a guitar signal on your BASS V-AMP PRO before running it through the effects.

(21) The stereo signal of the BASS V-AMP PRO without analog speaker

simulations can be taken at the ANALOG LINE OUTPUTS. For example, thisis how you connect an external stage amp when performing live.

(22) The POST DSP INSERT RETURN (IN) stereo jack pair is used for connecting

to the outputs of your external stereo eects processor. Thesignal taken at the POST DSP SEND (OUT) outputs (25) is brought back into these jacks.

(23) The ground connection on the DI OUT outputs (24) can be interrupted

with the GROUND LIFT switch. This way, rumble noise and ground loops can beavoided. The ground connection is interrupted when the switch is depressed (LIFT).
