13. System Configuration & OEM Controllers
13.1 Passive or Biamp?
The V15 is supplied as standard for passive operation via the internal crossover network and is
connected as shown in Figure 1. To reconfigure for Biamp operation simply follow the wiring
schematic as shown in Figure 2. This mode of operation bypasses the internal passive crossover
network and connects the input seakon connectors directly to the LF & HF sections of the driver
separately (see section 3.1 for connection details).
The Biamp controller parameters in section
13.3 must be adhered to for optimum performance.
A loudspeaker driven in Biamp mode offers a number of performance advantages, such as increased
system headroom. Audio program materiel is made up of many different frequencies and harmonics.
In music materiel, most of the energy is in the low frequencies, with less in the highs. When both
high and low frequencies are present in a signal, the stronger low frequencies can use up amp power,
leaving little or no reserve for the highs, so they are more likely to cause the power amplifier to clip. In
a Biamp driven system, a smaller amp can handle high frequencies, LF amp clipping is less of a
factor, and less overall amplifier capacity is needed due to the efficiency improvement in the absence
of a passive crossover.
