2. CONTROL ELEMENTS AND CONNECTIONS
1. INTRODUCTION
Thank you for expressing your confidence in our products by
purchasing the EHRINGER ULTRA ASS 115. This cabinet
is built with the outstanding UGERATM bass speaker. The
speaker cone is made of special high-quality paper that provides
rich bass tone and clear middle frequencies.
ass 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 ULTRA ASS 115 a high-value,
dependable companion on the stage, in the studio or in your
practice room.
1.1 Shipment
The 115 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 ULTRA ASS 115 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
Please take a few minutes and send us the completed warranty
card within 14 days of the date of purchase. You may also register
online at www.behringer.com. The serial number needed for the
registration is located in the back of the unit. Failure to register
your product may void future warranty claims.
2. CONTROL ELEMENTS AND
CONNECTIONS
Fig. 2.1.: Control elements and connections
You can connect a footswitch (e.g. MIDI FOOT
CONTROLLER FC 1010) 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 ULTRA ASS 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
the link 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.
+Please observe the illustrations 4.1 and 4.2.
SERI L NUMBER. Please take a few minutes and send us
the completed warranty card within 14 days of the date of
purchase; failure to do so may void future warranty claims.

3. APPLICATIONS
3. APPLICATIONS
With a variety of connectors and the option to combine your
115 with other EHRINGER equipment, there is a large number
of possible applications for your ULTRA ASS. The following
illustrations show a few of those.
Fig. 3.1: Mono setup with the ULTR B SS BX3000T
This illustration shows a simple setup with the EHRINGER
ULTRA ASS X3000T 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 ULTRA ASS X3000T output, or by
connecting only one cabinet directly to the amplifier, whereby the
signal is fed into the second cabinet with a cable (Link).

ULTRABASS BB115
3. APPLICATIONS
Fig. 3.4: Expanded stereo configuration
Fig. 3.3: Bi-amping: high and low frequencies are separately reproduced by the bass cabinets
When using the ASS V-AMP or the ASS V-AMP PRO, you
also have the option of using bass cabinets in the bi-amping mode.
With bi-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-end
signals are reproduced on the 115, while the mids and the
highs are reproduced on the 210. Splitting the frequency range
requires an active crossover.
This stereo setup is meant for all those who crave a saturated
stereo sound. Together with the ASS V-AMP or the
ASS V-AMP PRO, 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.
The ASS V-AMP and the ASS V-AMP PRO already feature
this function. Here, the frequencies are split in such a way that
the low-end signals 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-OVER function)
is explained in chapter 6.3 (post amp effects) in the
ASS V-AMP/ ASS V-AMP PRO manual.
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 115 and the 210 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®).

BEHRINGER is constantly striving to maintain the highest professional
standards. As a result of these efforts, modifications may be made from
time to time to e isting products without prior notice. Specifications and
appearance may differ from those listed or illustrated.
4. INSTALLATION
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-Ohm speakers 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-Ohm systems into one 4-Ohm system.
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.
