Behringer manual Shape Function, Connecting several loudspeakers, Ultrabass BX3000T as master

ULTRABASS BX3000T

+The D.I. output signal of your BX3000T is independent of the OUTPUT control’s setting. However, it depends on all remaining settings and the effects loop.

+If you own a tuner that is able to loop through and mute the signal, we recommend connecting it to

the effects loop and . This allows you to mute the output signal as long as you tune your instrument.

3.3 Connecting several loudspeakers

Needless to say, you can connect several loudspeakers (three at the most) to the speaker outputs of your BX3000T, which are wired in parallel. The figure below illustrates an example for such a connection.

+If several speakers are used in parallel, the total impedance should not drop below 4 W!

3.3.1Calculating 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 Ω loudspeakers ...

... or 1 x 8 Ω and 2 x 16 Ω:

+Please note that varying loudspeaker impedances result in different output power delivered to 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.

3.5Setup for master/slave operation

3.5.1ULTRABASS BX3000T as master

The LINE OUT jack allows you to connect the BX3000T 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.

3.5.2ULTRABASS BX3000T 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 BX3000T. The connected signal can be taken at the D.I. output. Use the OUTPUT control to set the volume level.

4. SHAPE FUNCTION

The SHAPE function on your BX3000T 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 BX3000T, because you can use the SHAPE filter for your fretless sound, and the basic sound for the jazz bass.
