    There are a large number of Martin Audio factory presets and configurations and these are being expanded all the time. It is always sensible to check your DX1.5 output channel allocations for the particular preset you have chosen to use before patching your system. This will ensure that the appropriate band is being routed to each loudspeaker section.
