+The BB115 can generate extremely high volume levels. Please bear in mind that high sound pressure can not only fatigue but also permanently damage your hearing. Always make sure to adjust your speaker cabinet to anappropriate volume level.





Thank you for expressing your confidence in our products by purchasing the BEHRINGER ULTRABASS BB115. This cabinet is built with the outstanding BUGERATM bass speaker. The speaker cone is made of specialhigh-qualitypaper that provides rich bass tone and clear middle frequencies.

Bass players, who love the warm and direct sound of a classic paper cone, will appreciate the high quality and workmanship as well as the extremely high power output of this speaker. All these characteristics make your ULTRABASS BB115 a high-value,dependable companion on the stage, in the studio or in your practice room.

1.1 Shipment

The BB115 was carefully packed at the assembly plant to assure secure transport. Should the condition of the cardboard box suggest that damage may have taken place, please inspect the unit immediately and look for physical indications of damage.

+Damaged equipment should NEVER be sent directly to us. Please inform the dealer from whom you acquired the unit immediately as well as the transportation company from which you took delivery. Otherwise, all claims for replacement/repair may be rendered invalid.

+Always use the original packing carton to prevent damage during storage or transport.

+Never let unsupervised children play with the ULTRABASS or with its packaging.

+Please dispose of all packaging materials in an environmentally friendly fashion.

1.2 Initial operation

Connect the ULTRABASS BB115 to a power amplifier using the speaker connectors located in the back.

+Please make sure to completely lower the volume on your amp before connecting it to the BB115.

1.3 Warranty

Fig. 2.1.: Control elements and connections

You can connect a footswitch (e.g. MIDI FOOT CONTROLLER FCB1010) to this 1/4" TS connector to remotely enable/disable the tweeter. When the tweeter is enabled, you get a harder, more direct sound (Hard Attack). When the tweeter is disabled, the entire sound spectrum is reproduced only on the bass speakers (Soft Attack).

The loudspeakers of the ULTRABASS series feature a 1/4" TS connector in the INPUT/LINK section as well as two professional speaker connectors (compatible with NEUTRIK® SPEAKON®). All connectors are wired in parallel, which means that all three connections are identical in their function. Therefore, you can connect a second speaker to thelink connector output without going directly to the amplifier. This way, you can utilize short cables and will require no additional connectors on your amp.

+Connecting several ULTRABASS cabinets via the link connector reduces the input impedance: if you connect two identical speakers, the impedance is reduced to one half of the original value, with three speakers to a third, and so on. Therefore, always keep in mind the impedance value of your amplifier to avoid causing damage by overloading. Ideally, the impedance of your speakers corresponds to the impedance of your amplifier. If the speaker has a higher impedance than the amplifier, this will have no negative consequences on the amp, but it won’t be able to pass its full power to the speaker. See chapter 4. “INSTALLATION” for more information.

+Attention! Never connect two amps to one BB115. Otherwise, you may destroy both your amps and your speakers.

This table shows the correct polarity of the connectors:

Plus pole (POS) = Tip (TIP) on the 1/4" TS connector or 1+ on the professional speaker connector.

Minus pole (NEG) = Sleeve (SLV) on the 1/4" TS connector or 1- on the professional speaker connector.

With a variety of connectors and the option to combine your BB115 with other BEHRINGER equipment, there is a large number of possible applications for your ULTRABASS. The following illustrations show a few of those.

Fig. 3.1: Mono setup with the ULTRABASS BX3000T

This illustration shows a simple setup with the BEHRINGER ULTRABASS BX3000T bass amplifier. This setup is particularly well suited for practice rooms and smaller venues. On larger stages, you can connect it to a mixing console via the DI Out connector. The equipment can be quickly assembled and disassembled, yet it is amazingly flexible.

Fig. 3.2: Expanded mono setup with different connectivity options for loudspeakers

This setup is recommended for gigs or practice with bigger bands. Here, two different cabinets are combined into a stack. Speaker connection is either done separately, so that each cabinet is connected to a separate ULTRABASS BX3000T output, or by

connecting only one cabinet directly to the amplifier, whereby the signal is fed into the second cabinet with a cable (Link). Also see .




Fig. 3.3: Bi-amping:high and low frequencies are separately reproduced by the bass cabinets

When using the BASS V-AMPor the BASSV-AMPPRO, you also have the option of using bass cabinets in thebi-ampingmode. Withbi-amping,high and low frequency ranges are split between different bass cabinets, so that the entire sound spectrum is not simultaneously reproduced on all speakers. In fig. 3.3,low-endsignals are reproduced on the BB115, while the mids and the highs are reproduced on the BB210. Splitting the frequency range requires an active crossover.

The BASS V-AMPand the BASSV-AMPPRO already feature this function. Here, the frequencies are split in such a way that thelow-endsignals are reproduced on the left channel, and the mids and the highs are reproduced on the right channel. How to make the necessary settings on the crossover(X-OVERfunction) is explained in chapter 6.3 (post amp effects) in the BASSV-AMP/BASSV-AMPPRO manual.

Fig. 3.4: Expanded stereo configuration

This stereo setup is meant for all those who crave a saturated stereo sound. Together with the BASS V-AMPor the BASSV-AMPPRO, stereo effects such as Chorus or Delay come alive. Real stereo effects require two separate cabinets set up to run in stereo. Our EUROPOWER EP2500 is perfect in the amplifier role. Additionally, with its 2 x 1,200 Watts, it has the necessary headroom to truly rock.

This is the expansion of the setup shown in fig. 3.3. Instead of powering two individual cabinets, the amp in fig. 3.4 powers each of the two stacks comprised of the BB115 and the BB210 cabinets. The cabinets are connected to one another using a link cable. Here, too, we recommend using only professional loudspeaker cables (compatible with NEUTRIK® SPEAKON®).





4.1 Speaker connector

When combining several speakers/cabinets, you should bear in mind the resulting overall impedance. Here are some brief explanations about different kinds of connections:

Serial connection: The individual impedance values of the connected speakers are added up. If two 4-Ohmspeakers are connected to one another, there is an overall impedance value of 8 Ohms.

Parallel connection: If speaker/cabinets with identical impedance “values are connected in parallel, the overall nominal impedance is reversely proportional to the number of speakers, e.g. if you connect two speakers/cabinets, the nominal impedance is halved; if you connect three speakers/cabinets, the nominal impedance is one third of the individual speakers’ impedance; with four speakers, it’s one quarter, and so on. For example, this way you can turn two 8-Ohmsystems into one4-Ohmsystem.

If four or more speakers/cabinets need to be connected, this can be done using a serial parallel connection. With four speakers with an impedance value of 4 Ohms each, the resulting overall impedance does not change.

+Whenever possible, try to use thick and short speaker cables to minimize power loss. Don’t lay output cables near input cables.

Wiring options for loudspeakers are additionally explained in the following illustrations and tables.
