IMPORTANT SAFETY INSTRUCTIONS
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this speaker cabinet near water.
) Clean only with dry cloth.
7) Before putting up the speaker cabinet, you will always have
to make sure that the ground surface is absolutely firm. A
surface that slightly vibrates is unsafe for the cabinet,
therefore: the cabinet should only be put up on firm, even
ground surfaces.
8) Do not put up your speaker cabinet near heat sources such
as radiators, heat registers, stoves, or other devices
(including amplifiers) that produce heat.
9) Only use attachments/accessories specified by the
manufacturer.
10) Use only with carts, stands, tripods, brackets or tables
specified by the manufacturer or sold with the cabinet. When
a cart is used, use caution when moving the cart/cabinet
combination to avoid injury.
11) Refer all servicing to qualified service personnel only.
Servicing is required when the cabinet has been damaged in
any way (e.g. when the power supply cord or plug have been
damaged), when liquid has been spilled into/onto the cabinet
or objects have fallen into the cabinet, the cabinet exposed
to rain or moisture, does not operate normally, or has been
dropped.
12) Please make sure that no objects or liquid reach the inside
of your cabinet through the openings.

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 an
appropriate volume level.

2. CONTROL ELEMENTS AND CONNECTIONS
2. CONTROL ELEMENTS AND
CONNECTIONS
Fig. 2.1.: Control elements and connections
You can connect a footsw tch (e.g. MIDI FOOT
CONTROLLER FCB1010) to th s 1/4" TS connector to
remotely enable/d sable the tweeter. When the tweeter s
enabled, you get a harder, more d rect sound (Hard Attack).
When the tweeter s d sabled, the ent re sound spectrum s
reproduced only on the bass speakers (Soft Attack).
The loudspeakers of the ULTRABASS ser es feature a
1/4" TS connector n the INPUT/LINK sect on as well as two
profess onal speaker connectors (compat ble w th
NEUTRIK® SPEAKON®). All connectors are w red n parallel,
wh ch means that all three connect ons are dent cal n the r
funct on. Therefore, you can connect a second speaker to
the l nk connector output w thout go ng d rectly to the
ampl f er. Th s way, you can ut l ze short cables and w ll
requ re no add t onal 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. To this end, make sure to adhere to the
advice given in chapter 4. INSTALLATION.
+Attention! Never connect two amps to one BA115.
Otherwise, you may destroy both your amps and your
speakers.
Th s table shows the correct polar ty of the connectors:
Plus pole (POS) = T p (TIP) on the stereo jack or 1+ on the
profess onal speaker connector.
M nus pole (NEG) = Sleeve (SLV) on the stereo jack or
1- on the profess onal speaker connector.
+Please observe the illustrations 4.1 and 4.2.

3. APPLICATIONS
W th a var ety of connectors and the opt on to comb ne your
BA115 w th other BEHRINGER equ pment, there s a large number
of poss ble appl cat ons for your ULTRABASS. The follow ng
llustrat ons show a few of those.
Fig. 3.1: Mono setup with the ULTR B SS BX3000T
Th s llustrat on shows a s mple setup w th the BEHRINGER
ULTRABASS BX3000T bass ampl f er. Th s setup s part cularly
well su ted for pract ce rooms and smaller venues. On larger
stages, you can connect t to a m x ng console v a the DI Out
connector. The equ pment can be qu ckly assembled and
d sassembled, yet t s amaz ngly flex ble.
Fig. 3.2: Expanded mono setup with different connectivity options for loudspeakers
3. APPLICATIONS
Th s setup s recommended for g gs or pract ce w th b gger
bands. Here, two d fferent cab nets are comb ned nto a stack.
Speaker connect on s e ther done separately, so that each cab net
s connected to a separate ULTRABASS BX3000T output, or by
connect ng only one cab net d rectly to the ampl f er, whereby the
s gnal s fed nto the second cab net w th a cable (L nk). Also see

ULTRABASS BA115
3. APPLICATIONS
Fig. 3.3: Bi-amping: high and low frequencies are separately resproduced by the bass cabinets
Fig. 3.4: Expanded stereo configuration
When us ng the BASS V-AMP or the BASS V-AMP PRO, you
also have the opt on of us ng bass cab nets n the b -amp ng mode.
W th b -amp ng, h gh and low frequency ranges are spl t between
d fferent bass cab nets, so that the ent re sound spectrum s not
s multaneously reproduced on all speakers. In f g. 3.3, low-end
s gnals are reproduced on the BA115, wh le the m ds and the
h ghs are reproduced on the BA210. Spl tt ng the frequency range
requ res an act ve crossover.
Th s stereo setup s meant for all those who crave a saturated
stereo sound. Together w th the BASS V-AMP or the
BASS V-AMP PRO, stereo effects such as Chorus or Delay truly
come al ve. Real stereo effects requ re two separate cab nets set
up to run n stereo. Our EUROPOWER EP2500 s perfect n the
ampl f er role. Add t onally, w th ts 2 x 1,200 Watts, t has the
necessary headroom to truly rock.
The BASS V-AMP and the BASS V-AMP PRO already feature
one such funct on. Here, the frequenc es are spl t n such a way
that the low-end s gnals are reproduced on the left channel, and
the m ds and the h ghs are reproduced on the r ght channel. How
to make the necessary sett ngs on the crossover (X-OVER
funct on) s expla ned n chapter 6.3 (post amp effects) n the
BASS V-AMP/BASS V-AMP PRO manual.
Th s s the expans on to the setup shown n f g. 3.3. Instead of
power ng two nd v dual cab nets, the amp n f g. 3.4 powers each
of the two stacks compr sed of the BA115 and the BA210 cab nets.
The cab nets are connected to one another us ng a l nk cable.
Here, too, we recommend us ng only profess onal loudspeaker
cables (compat ble w th 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 comb n ng several speakers/cab nets, you should bear
n m nd the result ng overall mpedance. Here are some br ef
explanat ons about d fferent k nds of connect ons:
Serial connection: The nd v dual mpedance values of the
connected speakers are added up. If two 4-Ohm speakers are
connected to one another, there s an overall mpedance value of
8 Ohms.
Parallel connection: If speaker/cab nets w th dent cal
mpedance values are connected n parallel, the overall nom nal
mpedance s reversely proport onal to the number of speakers,
e.g. f you connect two speakers/cab nets, the nom nal mpedance
s halved; f you connect three speakers/cab nets, the nom nal
mpedance s one th rd of the nd v dual speakers mpedance;
w th four speakers, ts one quarter, and so on. For example, th s
way you can turn two 8-Ohm systems nto one 4-Ohm system.
If four or more speakers/cab nets need to be connected, th s
can be done us ng a serial parallel connection. W th four
speakers w th an mpedance value of 4 Ohms each, the result ng
overall mpedance 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.
W r ng opt ons for loudspeakers are add t onally expla ned n
