Behringer UltraDrive Pro DCX2496 - Manual (Page 30)

30 ULTRADRIVE PRO DCX2496 User Manual
With two DCX2496 units you can even realize today’s most popular surround format:
5.1. In addition to the speaker cabinets and power amps (or active speakers as in
the simplified illustration shown here), all you need is a surround decoder to play
back pre-produced 5.1 material such as DVDs, or a mixing console with six outputs
(e.g. stereo out plus four subgroups). In the latter case, you can create highly
sophisticated surround mixes even without a special surround sound decoder.
The preset “5.1 FRONT” has been optimized for the L-C-R front speakers
with 2 speaker ways each (see also chapter 5.3). The three signals required
“Front-Left, Front-Center, Front-Right” are routed via the three inputs (A, B, C)
to the first DCX2496.
On the second DCX2496, the preset “5.1 REAR” should be used as a starting
point. It supplies the two rear surround speakers (also 2-way systems) plus the
monophonic sub-bass channel (“LFE” = “Low Frequency Enhanced”) with the
input signals “Rear-Left, Rear-Right and Sub-bass”, using connectors In A, B, C.
The sixth output of the second ULTRADRIVE PRO is not used in this application,
but is left available for additional effects or as a mono delay line.
