Effects Units and Processors Available with Hired PA Systems
We are introducing digital mixers at every level of production, and offboard equipment is being phased out as part of that process. However, we will retain offboard equipment for systems that feature analogue mixers until the process is complete, and some of the equipment detailed below is included with our remaining analogue-based systems. With any system, alternative combinations of equipment and patching options are available, although there may be a re-patching fee (please contact us if you require a different configuration). If you need general information about what these units do, please see our PA Equipment Guide section. Technical details of any specific item can usually be obtained from the manufacturer's website, but if you need information or a user guide for any equipment listed here and cannot find it online, please ask us.
Alternative rack-mounted equipment can include combinations of:
