ULTRABASS BX300

1. INTRODUCTION

With the BX300 you have acquired a state-of-the-artBass Workstation that sets new standards in bass amp engineering. Right from the start, our goal has been to design a revolutionary practice amp that stands out from the herd of “ordinary” bass amplifiers. And indeed, the BX300 gives you plenty of functionality and a broad range of connection and expansion options. In a word: you’ll be fascinated to find that the BX300 is a workstation with a character.

BEHRINGER is an audio engineering company that has been successfully developing professional 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 technicalknow-howcombined in your BX300.

We also set great store by flexibility, which 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 Workstation that offers you 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—whichcan only be achieved with innovative amplifiers. The unique ULTRABASS BX300 gives you pioneering sounds coming from an extremely compact design.

As technology advances, you’ve got to keep track of latest technological breakthroughs to avoid falling by the wayside. Which is what we did, by continuously improving this Bass Workstation and including many of your valuable suggestions.

Experience a new-generationBass Workstation with fascinating features:

sAstounding sound diversity through the SHAPE filter.

sState-of-the-artamplifier technology combined with abuilt-inbass cabinet give you precision in the treble and punch in the bass range.

sThe high-gradeandcustom-built10" speaker opens up new dimensions in terms of sound.

sThe rugged and compact design makes the ULTRABASS your favorite amp for club gigs and rehearsals.

sWith its highly useful expansion options, your BX300 is the perfect base for an expanded bass amplification set-up.

1.1 The concept

We designed the BX300 to finally start the world of bass amp design moving. Your absolutely low-noiseand indestructible Bass Workstation represents the current state of the art.

The robust cabinet is made of high-gradeandnon-pollutingE1-MDFboards, which are grooved,multi-gluedand free of formaldehydes. This is to make sure that your BX300 keeps working even when the going gets tough.

1.1.1 The 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 BX300 with our unique DYNAMIZER preamp circuit that gives you a lively and punchy sound with signal peaks—evenif 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 itsopto-limiterin the power stage it is virtually impossible to overdrive the ULTRABASS BX300.

1.2 Before you begin

Your BX300 was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit.

+If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted. Shipping claims must be made by the consignee.

Be sure that there is enough space around the unit for cooling and please do not place the ULTRABASS on high-temperaturedevices such as radiators etc. to avoid overheating.

+Before you connect your ULTRABASS to the mains, please make sure that your local voltage matches the voltage required by the unit:

The fuse holder on the female mains connector has 3 triangular markings, with two of these triangles opposing each other. The ULTRABASS is set to the operating voltage printed next to these markers and can be set to another voltage by turning the fuse holder by 180°. CAUTION: This instruction does not apply to export models exclusively designed, e.g. for 115-Voperation!

Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable safety standards.

+Please note that all units must be grounded properly. For your own safety, you should never remove any ground connectors from electrical devices or power cords or render them inoperative.

You will find additional information in chapter 4 “INSTALLATION”.

2.3 Set-upfor master/slave operation

2.3.1 ULTRABASS BX300 as master device

The PREAMP OUT jack allows you to connect the BX300 to an external power amp, using a commercial instrument cable equipped with mono phone plugs. Then, connect the PREAMP OUT jack to the input on the external power amp.

2.3.2 ULTRABASS BX300 as slave device 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 POWER AMP IN jack on your BX300.

3. THE SHAPE FUNCTION

The SHAPE function on your BX300 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—whichis 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, then use the SHAPE filter to create a very distinctive solo sound. Use the IN button to toggle between the two sounds.

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—twoinstruments 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 BX300, because you can use the SHAPE filter for your fretless sound, and the basic sound for the jazz bass.

4. INSTALLATION

4.1 Audio connections

Except for the tape input which has cinch connectors, all inputs and outputs of your BEHRINGER ULTRABASS are on mono 1/4" jacks.

+Please ensure that only qualified personnel install and operate the BX300. During installation and operation the user must have sufficient electrical contact to earth. Electrostatic charges might affect the operation of the unit.
