ULTRABASS BX4410/BX4410A
3.2Expanded setup with tuner and connection to a mixing console
The wiring scheme shown here builds on the standard setup.
Fig. 3.2: Expanded setup
The output signal of your BX4410/BX4410A 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. output signal of your BX4410/BX4410A 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 BX4410/BX4410A, 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 W loudspeakers ...
... or 1 x 8 W and 2 x 16 W:
+Please note that varying loudspeaker impedances result in different output power delivered to the individual speaker cabinets.
3.4Connection of a multi-effects processor
Use the SEND/TUNER jack to connect the bass signal to a
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 BX4410/BX4410A as master
The LINE OUT jack allows you to connect the BX4410/BX4410A 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 BX4410/BX4410A 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 BX4410/BX4410A. The connected signal can be taken at the D.I. output. Use the OUTPUT control to set the volume level.
