ULTRABASS BXR1800H

4.WIRING EXAMPLES

4.1Setup for practicing with playbacks

Fig. 4.1: Standard setup

This setup is intended for rehearsals or practicing at home. Connect the ULTRABASS as shown in Fig. 4.1. To feed in playbacks, connect a CD player to the CD input. Of course, you can also connect an MD player or a computer.

If you want to practice with headphones, just plug your headphones in the PHONES jack. The built-in loudspeaker will be muted automatically. Turn the MASTER control fully left before you connect the headphones.

4.2 Expanded setup for gigs and studio recordings

Fig. 4.2: Expanded setup

The following wiring scheme is recommended for live gigs or studio work. It builds on the standard setup.

Connect the footswitch supplied with the unit to the FOOT SW(ITCH) jack on the ULTRABASS. Use the footswitch to switch channels and to activate the Ultrabass function, which is particularly useful when playing live.

To use an external effects device, connect the input of the effects unit to the FX INSERT SEND on the ULTRABASS, and the output of the effects device to the FX INSERT RETURN. Instead of the floor effects shown here, you can also use a wah-wah pedal or an external 19" effects unit.

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 DIRECT OUTPUT 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.

4.3The 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.

4.4 ULTRABASS with one loudspeaker cabinet

The following figure shows a connection between a speaker cabinet and the SPEAKER OUTPUT jack of the BXR1800H head. The speaker cabinet’s impedance requires a minimum of 4 Ω.
