Fig. 3.3: Bi-amping: high and low frequencies are separately reproduced by the bass cabinets

When using the BASS V-AMP or the BASS V-AMP PRO, you also have the option of using bass cabinets in the bi-amping mode. With bi-amping, high and low frequency ranges are split between different bass cabinets, so that the entire sound spectrum is not simultaneously reproduced on all speakers. In fig. 3.3, low-end signals are reproduced on the BB115, while the mids and the highs are reproduced on the BB210. Splitting the frequency range requires an active crossover.

The BASS V-AMP and the BASS V-AMP PRO already feature this function. Here, the frequencies are split in such a way that the low-end signals are reproduced on the left channel, and the mids and the highs are reproduced on the right channel. How to make the necessary settings on the crossover (X-OVER function) is explained in chapter 6.3 (post amp effects) in the BASS V-AMP/BASS V-AMP PRO manual.

Fig. 3.4: Expanded stereo configuration

This stereo setup is meant for all those who crave a saturated stereo sound. Together with the BASS V-AMP or the BASS V-AMP PRO, stereo effects such as Chorus or Delay come alive. Real stereo effects require two separate cabinets set up to run in stereo. Our EUROPOWER EP2500 is perfect in the amplifier role. Additionally, with its 2 x 1,200 Watts, it has the necessary headroom to truly rock.

This is the expansion of the setup shown in fig. 3.3. Instead of powering two individual cabinets, the amp in fig. 3.4 powers each of the two stacks comprised of the BB115 and the BB210 cabinets. The cabinets are connected to one another using a link cable. Here, too, we recommend using only professional loudspeaker cables (compatible with NEUTRIK SPEAKON).

4. Installation

4.1 Speaker connector

When combining several speakers/cabinets, you should bear in mind the resulting overall impedance. Here are some brief explanations about different kinds of connections:

Serial connection: The individual impedance values of the connected speakers are added up. If two 4-Ohm speakers are connected to one another, there is an overall impedance value of 8 Ohms.

Parallel connection: If speaker/cabinets with identical impedance values are connected in parallel, the overall nominal impedance is reversely proportional to the number of speakers, e.g. if you connect two speakers/cabinets, the nominal impedance is halved; if you connect three speakers/cabinets, the nominal impedance is one third of the individual speakers’ impedance; with four speakers, it’s one quarter, and so on. For example, this way you can turn two 8-Ohm systems into one 4-Ohm system.
