2. Wiring Tips
Figures 2.1 and 2.2 show you how to connect your bass to the amplifier.
Fig. 2.2 shows a recommended setup for amplifying the sound of your BX1800
using a sound reinforcement system of any size. This way, you can also use your
amp for playing live or for rehearsals with your band.
If you want to use an effects unit (for example, the BEHRINGER X V-AMP PRO)
to experiment with some out-of-the-ordinary sounds, you can connect your bass
directly to the input of the unit. Then, connect a second cable from the effects
output to the input on your bass amp.

If you have an electronic tuner, please be sure to insert it pre effects device,
so that the tuner only receives a dry signal without effects components.

(1) Connect your bass to the INPUT jack, using a standard cable with a
1" TS connector.
(15) Use the balanced D.I. OUT XLR output to feed the audio signal from your
ULTRABASS to an external mixing console. The D.I. OUT signal is post-EQ.
(2) Press the PAD switch when using active instruments with high output levels. (16) Use the POWER switch to switch the BX1800 on or off. You should always

the PAD button has to be depressed.
make sure that the POWER switch is in the “Off” position when initially
connecting the unit to the mains.
(3) Pressing the SHAPE button will activate the Shape function. The Shape
function on your BX1800 provides a revolutionary type of filter that you can
use to modify your bass sound.
To disconnect the unit from the mains, pull out the main cord plug.
When installing the product, ensure that the plug is easily accessible.
◊
Please note: Merely switching the unit off does not mean that it
is fully disconnected from the mains. When not using the unit for
prolonged periods of time, please unplug the unit’s power cord from
the power outlet.
(4) Use the VOLUME control to adjust the volume of the instrument channel.
To change the balance between the instrument and CD volume level,
use your instrument’s volume control.
(5) The LOW control allows you to boost or cut the low-frequency range.
(6) Using the LOW MID control you can boost or cut the lower mids.
(7) The HIGH MID control allows you to boost or cut the upper mids.
(19)
(18)
(8) The HIGH control governs the high-frequency range to give your bass a more
“cutting” sound.
(9) Use the CD IN connectors to connect the output of your CD player, tape deck,
CD or MD walkman. This way you can play along to music or bass guitar
tutorial CDs.
(10) The BX1800 features an FX INSERT-Loop for external effects. Connect the
SEND output to the input of your effects device, for example, our proven
multi-effects processor BEHRINGER VIRTUALIZER PRO DSP2024P. This output
can also be used to connect your tuner.
(17)
(11) Connect the RETURN jack to the output of your effects device. Since the
BX1800 features a serial effects path, the mix ratio must be set on your
effects device.

(17) MAINS CONNECTION. Use the power cord supplied with the unit to connect
it to the mains.
(12) The PHONES jack is for headphones. When you plug in your headphones,
the built-in loudspeaker is muted.
(18) FUSE HOLDER/VOLTAGE SELECTOR. Before connecting the unit to the
mains, make sure that the voltage setting matches your local voltage.
A blown fuse should only be replaced by a fuse of the same type and rating.
On some units, the fuse holder can be switched to one of two positions,
i.e. 230 V and 120 V. When operating the unit outside Europe at 120 V,
a higher fuse rating is required.
◊
The headphone signal can also be routed to a mixing console or
sound reinforcement system. Connect the headphones output on
your BX1800 to the line input (LINE IN) on the console (for example,
BEHRINGER EURORACK UB1222FX-PRO). Please use a mono cable for
this application.
(19) SERIAL NUMBER.
◊
Some headphones produce distortion if the volume level is too high.
Please cut back the VOLUME control until the distortion disappears.
(13) Use the MASTER control to adjust the output level of the D.I. OUT output.
(14) The GND LIFT switch disconnects (switch pressed) the ground connection
at the D.I. OUT output to effectively eliminate hum noise resulting from
ground loops.
