ULTRABASS BX4410/BX4410A
3. WIRING EXAMPLES
3.2 Expanded 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 controls 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.
Fig. 3.3: Connection of two speaker cabinets
+ If several speakers are used in parallel, the total
impedance should not drop below 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 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.

3.5 Setup for master/slave operation
3.5.1 ULTRABASS 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.
3.5.2 ULTRABASS 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.
