ULTRABASS BXR1800H
2.CONTROL ELEMENTS AND CONNECTIONS
Fig. 2.1: The input section
INPUT. Connect your bass guitar to this input jack on the ULTRABASS (¼" TS jack).
The GAIN 1 control determines the input gain on channel 1.
Use the CH 2 button to switch between the two channels. The CH 2 button lights up when channel 2 has been activated. To switch channels, you can also use the supplied footswitch.
The GAIN 2 control sets the degree of distortion of channel 2. The further the control is turned clockwise, the higher the degree of distortion.
SHAPE is a special filter for your personal sound design. It gives you numerous options for shaping your bass sound. Application examples of the shape function can be found in section 3.2.2.
The Shape filter is only effective on channel 2. The signal in channel 1 remains unprocessed.
Use the LEVEL control to adjust the volume of channel 2. Use this control to achieve the balance in volume that you want between channels 1 and 2.
Fig. 2.2: The FBQ EQUALIZER
The FBQ EQUALIZER has 7 slide controls, one for each frequency band. The maximum boost/cut is 12 dB.
The FBQ switch activates the FBQ spectrum analyzer. The control LEDs, which are identical in brightness when FBQ is off, now show the energy content of each frequency band by lighting up with varying degrees of brightness. The equalizer function is always active, irrespective of the FBQ function. (For details on the FBQ function see section 3.2.1.)
Fig. 2.3: The master section
Use the MASTER control to set the overall volume.
The PHONES jack (¼" TRS jack) is for connecting a pair of headphones. You can use headphones from the BEHRINGER HP Series. This connector, when in use, mutes the
The POWER switch powers up your ULTRABASS. The POWER switch should always be in the “Off” position before you connect the ULTRABASS to the main power source.
Please note: The POWER switch does not fully disconnect the unit from the mains power cord plug or extention cord. To disconnect the unit from the main power source, pull out the main cord plug or appliance coupler. When installing the product, ensure the plug or appliance coupler is readily operable. Unplug the power cord when the unit is not used for prolonged periods of time.

Use the balanced DIRECT OUTPUT (XLR) to route the audio signal from the ULTRABASS to the input on a mixing console. The signal is taken from the point between the equalizer and the MASTER control.
The SPEAKER OUTPUT jack is used to connect to a speaker cabinet.
Your speaker cabinets should have a sufficient power rating (>180 W) and preferably a total impedance of 4 Ω to avoid speaker damage. Too high load impedance will decrease the output power rating of the power stage!
As an alternative to taking the signal from output 
, the LINE OUT signal (¼" TS jack) can also be used.
