ULTRABASS BXL450/BXL900/BXL1800/BXL3000
5. INSTALLATION
If you want the bass signal to go through a PA system during live
gigs, you would normally need a DI box. (DI boxes process the
signals for long cables and provide a higher output level at the
mixing console). The ULTRABASS amps have a DI box already
built in! Connect the balanced DI OUT directly to the mixing console
input or to the multi-core cable leading to the console. Use a
microphone cable (2-core shielded cable with XLR connectors).
Alternatively, you can use the LINE OUT (¼" TS jack) for short
cables and mixing consoles with line-level inputs (e.g. for
recording in your home studio without having to use a
microphone). Of course, you can also use this output as an
additional send path or to connect a tuner.
4.3 The ULTRABASS as a slave with an
external pre-amp
If you wish to use another bass preamp or modeling amp
(e. g. BASS V-AMP or BASS V-AMP PRO), you can connect this
amp to the FX INSERT RETURN jack. In this configuration, the
ULTRABASS is used as a power amp only, and the two input
channels are disabled.

5.1 Audio connections
Except for the headphones output, all ¼" jacks on the
BEHRINGER ULTRABASS are ¼" TS connectors. The DI output
is on a balanced XLR connector. The CD inputs are on RCA
connectors.

Please keep in mind that your ULTRABASS should
be installed and operated only by those who possess
sufficient technical knowledge about its installation
and operation. Everyone dealing with your
ULTRABASS should be sufficiently grounded both
during the installation as well as during actual usage.
Failure to do so may cause undesirable or faulty
operation due to electromagnetic discharges, etc.
