System C- Introducing Subs - Martin Audio THV User Manual

TH Series
System C‐ Introducing Subs
This system adds a pair of subwoofers to enhance the extreme sub frequency response of the system. On this example we have
used the SX218 twin 18" direct radiating ported subwoofer. The Martin Audio DX0.5 is again used for system processing, this
time using all six outputs to provide left and right outputs for sub, low and high frequencies. A DX1.5 or DX2 may also be used or
even a third party processor, parameters to program these are available in spreadsheet form on the Loudspeaker Settings page
on the Martin Audio website.
As well as applying the recommended equalisation the processor adds a limiter in the final stage of processing to protect the
system from being damaged by being over‐driven.
The XLR feeds from the mixer go to the inputs of the DX0.5, the DX0.5 outputs should be connected to the amplifier inputs with
short XLR cables. As with the basic system, a cable combines the outputs from the HF and LF amplifiers into a single speaker
cable to connect to the THV (or THH).
An additional amplifier is required, this is also fed from the processor and the outputs go directly to the SX218 with standard NL4
speaker cables.
