ULTRABASS BXR1800H  
Power is delivered via the cable that was delivered with the  
ULTRABASS. All mandatory safety precautions have been  
adhered to.  
1. INTRODUCTION  
Congratulations! With the ULTRABASS head, you have acquired  
a state-of-the-art bass amp that sets new standards. The  
ULTRABASS is an extremely powerful 2-channel bass amp. It  
gives you loads of power and makes sure that you always have  
a few extra watts available whenever you need them. The other  
items on the list of features are no less impressive: The  
ULTRABASS has one clean and one distortion channel plus one  
equalizer with a ground-breaking “see-what-you-play” FBQ  
frequency display, which immediately shows you which bass  
frequency is assigned to which control—the perfect solution for  
sound tuning as you play. A musical limiter circuit protects the  
unit effectively against distortion, even at maximum volume. The  
connectors for headphones and CD players are ideal for  
practicing.  
Please make sure that all of your equipment is  
grounded at all times. For your own protection, you  
should never tamper with the grounding of the cable  
or the unit itself. The unit shall always be connected  
to a mains socket outlet with a protective earthing  
connection.  
The sound quality may diminish within the range of  
powerful broadcasting stations and high-frequency  
sources. Increase the distance between the  
transmitter and the device and use shielded cables  
for all connections.  
This user’s manual will allow you to familiarize  
yourself with the control elements of your new  
ULTRABASS and learn all of its functions. After  
reading this manual, store it where you can easily  
find it for future reference.  
1.1.3 Online registration  
Please, do remember to register your new BEHRINGER equipment  
conditions of our warranty carefully.  
Should your BEHRINGER product malfunction, our goal is to have  
it repaired as quickly as possible. To arrange for warranty service,  
please contact the retailer from whom the equipment was  
purchased. Should your BEHRINGER dealer not be located in  
your vicinity, you may directly contact one of our subsidiaries.  
Corresponding contact information is included in the original  
equipment packaging (Global Contact Information/European  
Contact Information). Should your country not be listed, please  
contact the distributor nearest you. A list of distributors can be  
found in the support area of our website (www.behringer.com).  
1.1 Before you get started  
1.1.1 Shipment  
The ULTRABASS was carefully packed at the assembly plant to  
ensure secure transport.  
If the cardboard box is damaged, please inspect the ULTRABASS  
equipment immediately for physical damage.  
Damaged equipment should NEVER be sent directly  
to us. Immediately inform the dealer from whom  
you acquired it as well as the transportation  
company from which you took delivery. Otherwise,  
all claims for replacement/repair may be rendered  
invalid.

process your repair claims quicker and more efficiently.  
Thank you for your cooperation!  
If the unit needs to be shipped, please always use  
the original packaging to avoid damage.  
Never let unsupervised children play with the  
device or with its packaging.  
Please dispose of all packaging materials in an  
environmentally-friendly fashion.  
1.1.2 Initial operation  
Please make sure that your ULTRABASS is provided with  
sufficient ventilation, and never place it on other amplifiers or in  
the vicinity of a heater to avoid the risk of overheating.  
Before plugging your ULTRABASS into a power  
socket, please make sure you have selected the  
correct voltage:  
The fuse retainer near the power cord connector has three  
triangular markings. Two of these triangles point in opposite  
directions. Your ULTRABASS 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 your ULTRABASS unit with a different  
voltage, you must change the fuses accordingly.  
The correct value of the fuses needed can be found  
in the section “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  
section “SPECIFICATIONS”.

2. CONTROL ELEMENTS  
AND CONNECTIONS  
Fig. 2.3: The master section  
Use the MASTER control to set the overall volume.  
The PHONES jack (¼" TRS jack) is for connecting a pair of  
headphones. You can use headphones from the  
BEHRINGER HP Series. This connector, when in use, mutes  
the built-in bass speaker.  
Fig. 2.1: The input section  
INPUT. Connect your bass guitar to this input jack on the  
ULTRABASS (¼" TS jack).  
The POWER switch powers up your ULTRABASS. The  
POWER switch should always be in the “Off” position before  
you connect the ULTRABASS to the main power source.  
The GAIN 1 control determines the input gain on channel 1.  
Use the CH 2 button to switch between the two channels.  
The CH 2 button lights up when channel 2 has been  
activated. To switch channels, you can also use the  
supplied footswitch.  
Please note: The POWER switch does not fully  
disconnect the unit from the mains power cord  
plug or extention cord. To disconnect the unit from  
the main power source, pull out the main cord plug  
or appliance coupler. When installing the product,  
ensure the plug or appliance coupler is readily  
operable. Unplug the power cord when the unit is  
not used for prolonged periods of time.  
The GAIN 2 control sets the degree of distortion of  
channel 2. The further the control is turned clockwise,  
the higher the degree of distortion.  
SHAPE is a special filter for your personal sound design. It  
gives you numerous options for shaping your bass sound.  
Application examples of the shape function can be found  
in section 3.2.2.  
The Shape filter is only effective on channel 2. The  
signal in channel 1 remains unprocessed.  
Use the LEVEL control to adjust the volume of channel 2.  
Use this control to achieve the balance in volume that you  
want between channels 1 and 2.  
Fig. 2.4: The rear-panel connectors  
Use the balanced DIRECT OUTPUT (XLR) to route the  
audio signal from the ULTRABASS to the input on a mixing  
console. The signal is taken from the point between the  
equalizer and the MASTER control.  
Fig. 2.2: The FBQ EQUALIZER  
The FBQ EQUALIZER has 7 slide controls, one for each  
frequency band. The maximum boost/cut is 12 dB.  
The SPEAKER OUTPUT jack is used to connect to a  
speaker cabinet.  
The FBQ switch activates the FBQ spectrum analyzer.  
The control LEDs, which are identical in brightness when  
FBQ is off, now show the energy content of each  
frequency band by lighting up with varying degrees of  
brightness. The equalizer function is always active,  
irrespective of the FBQ function. (For details on the FBQ  
function see section 3.2.1.)  
Your speaker cabinets should have a sufficient  
power rating (>180 W) and preferably a total  
impedance of 4 to avoid speaker damage. Too  
high load impedance will decrease the output power  
rating of the power stage!  
As an alternative to taking the signal from output  
, the  
LINE OUT signal (¼" TS jack) can also be used.

cable is provided with the unit.  
To distort sounds, use channel 2. On channel 2, you can also  
create an alternative sound: one that is louder than or shaped  
differently from the sound on channel 2. (For details about the  
Shape control, see section 3.2.) Use the GAIN 2 control  
to  
adjust the input level of channel 2. This control also allows you to  
determine the amount of distortion. If the signal becomes too  
loud, you can use the LEVEL control  
to cut back the volume  
and align it with the volume of channel 1. This way, you can  
avoid drastic level changes when switching channels.  
3.2 Sound processing  
The ULTRABASS offers a variety of features to modify your  
bass sound. These processing functions are described in this  
section.  
3.2.1 The FBQ equalizer  
The equalizer is a graphic 7-band EQ incorporating an FBQ  
spectrum analyzer. When a slide control is set to the zero position,  
the instrument signal remains unprocessed in the relevant  
frequency band.  
Fig. 2.6: COMPRESSOR function  
The COMPRESSOR control governs the compression  
intensity (see section 3.2.4).  
Use the ON switch to activate the compressor.

3.2.4 The compressor  
slide control upwards.  
A compressor is used to limit the dynamic range of a signal.  
Signal peaks are lowered and soft signals are raised in volume,  
thus reducing the difference between the highest and the lowest  
signal levels. The result is a much more powerful sound.  
V
To lower its volume, move the control downwards.  
Each control has an LED which displays the level of the  
respective frequency band by lighting up with varying degrees  
of brightness. This feature helps you find the control(s) that you  
Some playing techniques, such as slapping, lead to high-level

need for sound processing. Press the FBQ switch  
to switch  
on the FBQ display. For example, if the sound is muddy or booming  
at 160 Hz, this is shown by a brightly lit LED in the corresponding  
control. Move the 160-Hz control down a bit (negative range) to  
eliminate the booming sound. Conversely, you can accentuate  
certain signal ranges that lack presence (LED lights up only  
faintly) by moving the relevant controls upwards.

slowly to the right to  
You don’t have to raise the volume of a frequency  
range to make it seem louder. Instead, you can  
lower the other frequency ranges by moving their  
slide controls downwards. This prevents the  
internal signal level from becoming too high and  
also gives you some valuable dynamics headroom.  
V
Press the ON switch to compare the compressed signal  
with the unprocessed one.  
Compressors work best if provided with high input signals. If the  
signal level is low, the effect will be activated only with high  
settings. If so, enabling the compressor can lead to extreme  
level differences. If GAIN is high, the compressor comes in quite  
early. In this case, you don’t need to turn up the COMPRESSOR  
control that far to achieve an effect. Experiment with it to find the  
best setting for your needs!  
3.2.2 The Shape function  
The Shape function on your ULTRABASS provides a  
revolutionary type of filter that you can use to modify your bass  
sound completely. The filter allows you to shape your sound—  
which is a must for bass players today. Extreme filter settings  
will give your bass sound more punch, for example:  
The compressor works independently of the built-  
in protective limiter, which is always active and  
protects the power amplifier from overload and  
hence distortion.  
You want to play a live bass solo but the sound doesn’t cut  
through. The solo should stand out, rather than being drowned.  
First, set up a solid basic sound on channel 1. Then, create a  
very distinctive solo sound on channel 2 using the Shape filter.  
Since the Shape filter is only effective on channel 2, you can  
change sounds quickly and easily before you begin your solo.  
The Shape filter is worth its weight in gold when you are using  
two different bass guitars. Maybe you want to change from one  
instrument to another with a completely different sound. During  
gigs you often lack the time to set up your amp for a different  
instrument. Because you can use channel 1 for one instrument  
and channel 2, with its Shape filter, for another instrument, you’ll  
be glad to have the ULTRABASS.  
3.2.3 The Ultrabass function  
In current music productions, extremely low bass sounds that  
are one octave below the lowest available bass guitar frequency  
are quite popular. Often, you can only create this sound in studios,  
because most bass amplifiers have no sub-harmonics function.  
This is not true with the ULTRABASS. The Ultrabass processor  
gives you the ultimate tool to shape this contemporary sound.  
You’ll be amazed to hear how deep your bass can sound with  
the Ultrabass function. Extreme settings can be particularly  
interesting if you want to give your sound added sparkle in the  
treble range. By the way, if you already set the Shape filter to  
create punchy sounds, but feel that there’s not enough power in  
the bass range, the sub-harmonics processor is there to help  
you. Even if the sound is still punchy, it will have much more depth.  
The Ultrabass function can be controlled with the supplied  
footswitch, in order to emphasize certain passages, for example.

ULTRABASS BXR1800H  
To use an external effects device, connect the input of the  
effects unit to the FX INSERT SEND on the ULTRABASS, and the  
output of the effects device to the FX INSERT RETURN. Instead  
of the floor effects shown here, you can also use a wah-wah  
pedal or an external 19" effects unit.  
4. WIRING EXAMPLES  
4.1 Setup for practicing with playbacks  
If you want the bass signal to go through a PA system during live  
gigs, you would normally need a DI box. (DI boxes process the  
signals for long cables and provide a higher output level at the  
mixing console). The ULTRABASS amps have a DI box already  
built in! Connect the balanced DIRECT OUTPUT directly to the  
mixing console input or to the multi-core cable leading to the  
console. Use a microphone cable (2-core shielded cable with  
XLR connectors).  
Alternatively, you can use the LINE OUT (¼" TS jack) for short  
cables and mixing consoles with line-level inputs (e.g. for  
recording in your home studio without having to use a  
microphone). Of course, you can also use this output as an  
additional send path or to connect a tuner.  
4.3 The ULTRABASS as a slave with an  
external pre-amp  
If you wish to use another bass preamp or modeling amp  
(e. g. BASS V-AMP or BASS V-AMP PRO), you can connect this  
amp to the FX INSERT RETURN jack. In this configuration, the  
ULTRABASS is used as a power amp only, and the two input  
channels are disabled.  
Fig. 4.1: Standard setup  
This setup is intended for rehearsals or practicing at home.  
Connect the ULTRABASS as shown in Fig. 4.1. To feed in  
playbacks, connect a CD player to the CD input. Of course, you  
can also connect an MD player or a computer.  
4.4 ULTRABASS with one loudspeaker cabinet  
The following figure shows a connection between a speaker  
cabinet and the SPEAKER OUTPUT jack of the BXR1800H head.  
The speaker cabinet’s impedance requires a minimum of 4 .  
If you want to practice with headphones, just plug your  
headphones in the PHONES jack. The built-in loudspeaker will be  
muted automatically. Turn the MASTER control fully left before  
you connect the headphones.  
4.2 Expanded setup for gigs and studio recordings  
Fig. 4.3: Connecting a speaker cabinet  
Fig. 4.2: Expanded setup  
The following wiring scheme is recommended for live gigs or  
studio work. It builds on the standard setup.  
Connect the footswitch supplied with the unit to the FOOT  
SW(ITCH) jack on the ULTRABASS. Use the footswitch to switch  
channels and to activate the Ultrabass function, which is  
particularly useful when playing live.
