6 ULTRABASS BX1800 User Manual
(1) Connect your bass to the INPUT jack, using a standard cable with a
¼" TS connector.
(2) Press the PAD switch when using active instruments with high output levels.
In this case the INPUT jack features 6 dB less gain. For passive instruments
the PAD button has to be depressed.
(3) Pressing the SHAPE button will activate the Shape function. The Shape
function on your BX1800 provides a revolutionary type of lter that you can
use to modify your bass sound.
(4) Use the VOLUME control to adjust the volume of the instrument channel.
Tochange the balance between the instrument and CD volume level,
useyour 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.
(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 eects. Connect the
SEND output to the input of your eects device, for example, our proven
multi-eects processor BEHRINGER VIRTUALIZER PRO DSP2024P. This output
can also be used to connect your tuner.
(11) Connect the RETURN jack to the output of your eects device. Since the
BX1800 features a serial eects path, the mix ratio must be set on your
eects device.
(12) The PHONES jack is for headphones. When you plug in your headphones,
thebuilt-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.
(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 eectively eliminate hum noise resulting from
groundloops.
(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.
(16) Use the POWER switch to switch the BX1800 on or o. You should always
make sure that the POWER switch is in the “O” position when initially
connecting the unit to the mains.
To disconnect the unit from the mains, pull out the main cord plug.
Wheninstalling 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.
