Genelec 1094A, 1092A manual Subwoofer in Analogue Matrix Surround Sound systems

Subwoofer in Analogue Matrix Surround Sound systems.

When using a single subwoofer in an analogue matrix surround sound system, such as Dolby Surround or Dolby Pro-Logic, only the front three

channels should be connected to the subwoofer inputs (see figure 9 above). All front channels that are used should be connected via the subwoofer so that the output of the subwoofer is matched to the rest of the system. All other surround sound channels should be connected as normal.

If there is a subwoofer channel output on the decoder it should NOT be connected to the subwoofer speaker since the filtering within the decoder will effect the performance of the subwoofer.

Digital decoders, for example, Dolby Digital Surround (AC-3), DTS and DMAG2, have a discrete subwoofer channel output which should be

connected to the sub input on the 1092A or 1094A (see figure 10 above). This enables the subwoofer to correctly reproduce all the sub-bass information in the mix. Genelec Subwoofers can be used to good effect in “Discrete 5.1” system surround channels as they are wide band.

Digital decoders do not limit the bandwidth of the rear channels. If necessary, a second Genelec 1092A or 1094A subwoofer can be connected to the rear channels.
