ULTRABASS BX4210A/BX4210
1. INTRODUCTION
1. INTRODUCTION
Congratulations! With the BX4210A/BX4210 you have acquired
a pro-level amplifier from our BX bass amplifier series. This
revolutionary bass amplifier has many of the features of our
successful BX1200. Our top goal when designing the BX4210A/
BX4210 was to set new standards. In fact, the BX4210A/BX4210
is a bass amp that gives you a full set of features plus a
comprehensive range of connection and expansion options. With
this amp youll certainly rattle the planet!
BEHRINGER is an audio engineering company that has been
successfully developing products for studio and live applications
for many years now. Our range of products includes
microphones and a variety of 19" devices (compressors,
enhancers, noise gates, tube processors, headphone amps,
digital effects devices, DI boxes, etc.) as well as monitoring and
P.A. speakers plus professional live and recording consoles.
You will find all of our technical know-how combined in your
BX4210A/BX4210.
Flexibility has become a particularly important factor in the
music business over the past few years. Modern bass players
need to offer a broad range of sounds, but should still be able to
play in different kinds of applications at short notice: home
recording, studio, live concerts. For this reason, it has always
been our prime concern to give you a bass amplifier that offers
a complete set of useful functions, but can still be operated
intuitively and quickly.
Additionally, the world of electric bass playing has changed:
new basses, with five or six strings, are being launched all the
time, there are effects devices and the desire to create ones
own unique soundwhich can only be achieved with
innovative amplifiers. Our unique ULTRABASS BX4210A/BX4210
gives you pioneering sounds and power galore.
We have expanded our BX Series with this amplifier to give
you all the freedom you need when expanding your set-up. No
matter which speakers or cabinets you preferwith its superb
sound, your BX4210A/BX4210 will bring some life into your
speaker.
As technology advances, youve got to keep track of the latest
technological breakthroughs to avoid falling by the wayside.
Which is what we did, by continuously improving this bass
amplifier and including many of your valuable suggestions.
Experience a new-generation bass amp with fascinating
features:
sOriginal BUGERA 10" Hard Attack aluminum-cone
speakers and switchable 1" custom-made horn tweeter.
sAstounding sound diversity through SHAPE filter and
ULTRABASS sub-harmonics processor.
sUnbelievable punch through innovative Dynamizer preamp
technology.
sMore gain, but no distortion through built-in limiter.
sOptimum level metering through clearly visible VU meter.
sA 5-band EQ with additional Deep and Bright functions
meets all requirements in terms of tone-shaping.
sPlenty of power plus a built-in DI outputeven on big stages
youll cut a fine figure with your BX4210A/BX4210.
1.1 The design concept
This absolutely low-noise and indestructible bass amp
represents the current state of the art.
The rugged enclosure of your ULTRABASS ensures that the
unit will withstand rough handling on the road over many years.
1.1.1 Patented Dynamizer technology
When it comes to amplifying the signals delivered by electric
instruments, youve got to separate the wheat from the chaff.
Unlike mixed or mastered signals, electric instruments usually
deliver extremely high signal peaks which, when raised in gain,
produce nasty distortion. How an amplifier responds to these
signal peaks can therefore be seen as one of its most essential
quality features.
Many manufacturers use limiters preceding the power stage
to limit dynamic signal peaks. However, the problem is the preamp,
which is why weve equipped the BX4210A/BX4210 with our
unique Dynamizer preamp circuitry that gives you a lively and
punchy sound with signal peakseven if the amp reaches its
power limits. Extreme signal peaks are limited effectively while
the average level and hence the power of the overall signal is
raised. The sound gets more vivid and powerful in character,
without any unmusical distortion. With its limiter in the power
stage it is virtually impossible to overdrive the ULTRABASS
BX4210A/BX4210.
1.2 Before you get started
1.2.1 Shipment
Your BX4210A/BX4210 was carefully packed at the factory

The output signal of your BX4210A/BX4210 can be taken
directly at the XLR D.I. output and fed to a microphone input of
your mixing console using a balanced microphone cable. Please
ensure that phantom power is switched off on the respective
channel of your mixer!
+The D.I. utput signal f y ur BX4210A/BX4210 is
independent f the OUTPUT c ntr ls setting.
H wever, it depends n all remaining settings and
the effects l p.
+If y u wn a tuner that is able t l p thr ugh and
mute the signal, we rec mmend c nnecting it t
the effects l p and . This all ws y u t mute
the utput signal as l ng as y u tune y ur instrument.
3.3 Connecting several loudspeakers
Needless to say, you can connect several loudspeakers (three
at the most) to the speaker outputs of your BX4210A/BX4210,
which are wired in parallel. The figure below illustrates an
example for such a connection.
Fig. 3.3: Connection of two speaker cabinets
+If several speakers are used in parallel, the t tal
impedance sh uld n t dr p bel w 4 W!
3.3.1 Calculating the total impedance when
connecting several loudspeakers
If several speakers are used in parallel, their total impedance
can be calculated as follows:
E.g. this would allow two 8 W loudspeakers ...
... or 1 x 8 W and 2 x 16 W:
+Please n te that varying l udspeaker impedances
result in different utput p wer delivered t the
individual speaker cabinets.
3.4 Connection of a multi-effects processor
Use the SEND/TUNER jack to connect the bass signal to a
multi-effects device or a compressor. The output level is
independent on the position of the OUTPUT control.
The RETURN jack should be connected to the output of your
effects device. If this jack is used for connection, the direct
signal is interrupted automatically. The ratio between direct and
effects signal has to be set on your effects device.
Fig. 3.4: Connection of a multi-effects processor
3.5 Setup for master/slave operation
3.5.1 ULTRABASS BX4210A/BX4210 as master
The LINE OUT jack allows you to connect the BX4210A/BX4210
to an external power amp, using a commercial instrument cable
equipped with mono phone plugs. The signal present here is
independent on the position of the OUTPUT control.
3.5.2 ULTRABASS BX4210A/BX4210 as slave
controlled by an external amp/preamp
To use the power amp of your ULTRABASS for an external
amp or preamp, you need to connect the line output of the
external amplifier to the RETURN jack on your BX4210A/BX4210.
The connected signal can be taken at the D.I. output. Use the
OUTPUT control to set the volume level.

ULTRABASS BX4210A/BX4210
4. SHAPE FUNCTION
The SHAPE function on your BX4210A/BX4210 provides a
revolutionary type of filter that you can use to modify your bass
sound in full detail. 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 power, for example:
You want to play a live bass solo but the sound doesnt cut
through. The solo should stand out, rather than being drowned.
Set up a solid basic sound plus a very distinctive solo sound
using the SHAPE filter. Connect your footswitch to control the
SHAPE filter.
The SHAPE filter is a bargain when you are using two different
bass guitars. Maybe you want to change from a jazz bass to a
fretless bass, and vice versatwo instruments with a completely
different sound. During gigs you often lack the time to set up
your amp for a different instrument, so youll be happy to have a
BX4210A/BX4210, because you can use the SHAPE filter for
your fretless sound, and the basic sound for the jazz bass.
5. ULTRABASS FUNCTION
Extremely low bass sounds playing one octave below the
lowest available bass guitar frequency are quite trendy in current
music productions. Often, you can do this in studios only, because
most bass amplifiers have no sub-harmonics function. Not so
with your BX4210A/BX4210: the ULTRABASS processor gives
you the ultimate tool to shape up-to-date sounds.
Youll be surprised how deep your bass can sound with the
ULTRABASS function of your BX4210A/BX4210. Extreme
settings can be particularly interesting if you want to give your
sound some flavor in the treble range. By the way: when you
use the SHAPE filter set to a low cut-off frequency (which is a
nice setting for growling sounds), but feel that theres not enough
power in the bass range, the sub-harmonics processor will be
there to help you: even though the sound is still growling, now it
has much more depth.
The ULTRABASS function can easily be switched on and off
via the supplied footswitch. This allows you to fine-tune certain
passages only.
6. INSTALLATION
6.1 Mains connection
The mains connection is made by using the enclosed mains
cable and a standard IEC receptacle. It meets all of the
international safety certification requirements.
+Please make sure that all units have a pr per
