Connect your bass to the INST INPUT jack, using a standard
cable with a 1/4" TS connector.
Press the ACTIVE switch when using active instruments
with high output levels. In this case the INST INPUT jack
features 10 dB less gain. For passive instruments the
ACTIVE button has to be depressed.
Pressing the MID 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.
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.
The LOW control allows you to boost or cut the low-
frequency range.
Using the LOW MID control you can boost or cut the lower
mids.
The HIGH MID control allows you to boost or cut the upper
mids.
The HIGH control governs the high-frequency range to
give your bass a more “cutting” sound.
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.
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.
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.
The PHONES jack is for headphones. When you plug in
your headphones, the built-in loudspeaker is muted.
+
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.
+
Some headphones produce distortion if the volume
level is too high. Please cut back the VOLUME control
until the distortion disappears.
Use the LINE LEVEL control to adjust the output level of
the LINE OUT output.
The GROUND LIFT switch disconnects (switch pressed)
the ground connection at the LINE OUT output to effectively
eliminate hum noise resulting from ground loops.
Use the balanced LINE OUT XLR output to feed the audio
signal from your ULTRABASS to an external mixing console.
The LINE OUT signal is post-EQ.
Use the POWER switch to switch the BX1800 on or off.
You should always make sure that the POWER switch is in
the “Off” position when initially connecting the unit to the
mains.
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.

MAINS CONNECTION. Use the power cord supplied with
the unit to connect it to the mains.
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.
