and the subwoofer cancel each other out at certain frequencies and positions. To check this, walk around the room and listen to the difference between X-OVER switched on and off. It is therefore possible to hear more bass without a subwoofer or by using the crossover function even with full range speakers.

3.2 The Integrated Limiter

Devices of this kind produce bass frequencies with hazardous levels, which can overload or damage your loudspeaker systems. For this reason, the ULTRABASS PRO integrates a level limiter which monitors and if necessary reduces the low-frequency level of the generated output signal. The limiter controls both temporary signal peaks to avoid distortion, as well as constant overloading to prevent the speakers from being damaged. If excessive signal levels are detected, the limiter follows the THRESHOLD setting and reduces the output signal amplitude to a value below distortion. The setting of this control depends on numerous factors, such as level and low-frequency contents in the program material, overall level, the amplifier’s capacity, the loudspeaker’s power rating etc. As a rule of thumb it is recommended to adjust the THRESHOLD control so that the first two LEDs of the gain reduction meter light up. The setting should be checked by ear.

In addition to its function as a protection device, the limiter can also be used as an effect to provide constant power. For this purpose, the THRESHOLD control is adjusted in such a way that the limiter responds all the time and thus provides a constant low-frequency level, without losing the dynamic punch of the program material. In this setup, it should be observed that a correct ratio between the BASS LEVEL and THRESHOLD controls is maintained.

+Be careful when using the ULTRABASS PRO: excessive use can damage your loudspeaker system. The low-frequency signals produced by the ULTRABASS PRO can highly stress both amplifier and low-frequency speakers. So, do not exaggerate the effect, use the integrated limiter and observe the power rating of your system!

4. INSTALLATION

4.1 Audio Connections

The audio inputs and outputs on the BEHRINGER ULTRABASS PRO are fully balanced. If possible, connect the unit to other devices in a balanced configuration to allow for maximum interference immunity.

+Please ensure that only qualified persons install and operate the ULTRABASS PRO. During installation and operation the user must have sufficient electrical contact to earth. Electro- static charges might affect the operation of the ULTRABASS PRO!

You will find further information in chapter 1.2 “Before you begin”.
