PA DEMO at CX Roadshow – national tour

11 February 2013

Come along at 2pm or 4pm (repeat) for this demo session, run by Jimmy Den Ouden from CX.

The demonstration is designed to show a range of composite PA systems from various manufacturer. A brief fact sheet will be supplied detailing brands, model numbers and other short-form information.

Each system will be introduced using a standard dynamic vocal mic. This should give some representation of live vocal rendition across the various systems, or at least a starting point from which to form your opinion.

All systems will be run with pink noise to a level of 91dBA. Level calibration and measurement will be done live at the start of the demonstration. SPL will be measured with an NTI ML-1 analyser and Mini-SPL reference mic.

Playback will be via Macbook Pro output to a Roland UA-25 USB audio interface, linked to a Soundcraft Si Compact console. A Marantz DV-4610 DVD player will be connected via AES to the console as a backup playback. Each system will be driven from a mix send output. Stereo sources will be summed and sent to the various systems in mono. Systems have been setup as deemed appropriate by their representatives, and we expect to see relatively standard factory tuning parameters applied.

A selection of musical tracks has been chosen for playback on each system, each track with a different purpose in mind. See the listening notes attached for details. All tracks have been captured direct from CD in WAV format, and will be played out with no processing or compression applied other than level matching. Tracks have been matched in level as closely as possible for consistent presentation, the exception being the final two tracks which will be played at a higher levels.
