ULTRABASS BXR1800H
+ 
FX INSERT: The ULTRABASS features a serial insert path, which allows you to connect external effects devices (e. g.
processors). Connect the SEND jack 
to the input on the effects device. Connect the output on the effects
device to the RETURN jack 
on the ULTRABASS. In the signal path of the amplifier, the FX insertion point occurs before the Ultrabass processor (
).
The INSERT SEND can also be used as a parallel output, for example, to connect a tuner. As long as the RETURN jack is not in use, there will be no break in the internal signal path.
SERIAL NUMBER.
The CD IN input (RCA) allows you to connect an external stereo signal. For instance, you can play along with your favorite songs played back from CD or MD, or with a drum computer.
The BXR1800H head includes a dual footswitch. Connect the footswitch to the FOOT SW(ITCH) jack. Use the footswitch to select a channel (corresponds to the CH 2
button 
) and to activate the Ultrabass function
(corresponds to the ON button 
).

FUSE RETAINER/VOLTAGE SELECTOR. Please make sure that the voltage indicated by the voltage selector matches the local voltage before you connect the unit to the main power supply. Always replace blown fuses with fuses of the same type and rating. Some units feature a fuse retainer in which a selection between 230 V and 120 V is possible. Please be aware: When using your unit outside Europe and with 120 V, a fuse with a higher rating is required.
Power is supplied via an IEC connector. The matching cable is provided with the unit.

3.FIRST STEPS
3.1Connect your bass and get started
We’re sure you cannot wait to set up and connect your ULTRABASS amp and check out its sounds. So, let’s get going!
Connect your instrument to the input jack 
before you switch on the unit. Use a standard instrument cable with ¼" TS connectors.
Turn the MASTER control 
fully to the left, then switch off the equalizer, compressor and Ultrabass function
(buttons 
, 
and 
) to start off with a neutral sound.
Set the GAIN control to
Switch on the ULTRABASS using the POWER switch 
, then adjust the desired volume level using the MASTER
control 
.
The ULTRABASS has two input channels to be selected with
the channel selector 
. When channel 1 is active (button LED
off), the GAIN 1 control 
can be used to adjust the input sensitivity.
To distort sounds, use channel 2. On channel 2, you can also create an alternative sound: one that is louder than or shaped differently from the sound on channel 2. (For details about the
Shape control, see section 3.2.) Use the GAIN 2 control 
to adjust the input level of channel 2. This control also allows you to determine the amount of distortion. If the signal becomes too
loud, you can use the LEVEL control 
to cut back the volume and align it with the volume of channel 1. This way, you can avoid drastic level changes when switching channels.
3.2 Sound processing
The ULTRABASS offers a variety of features to modify your bass sound. These processing functions are described in this section.
