Semaphore - Port Adelaide RSL



Located in a historic building on the bustling foreshore of Semaphore Beach, South Australia, the Semaphore. Port Adelaide RSL turned to Integrated Audio Solutions to consider and resolve a number of distinct audio-visual upgrade requirements.

Charged with overseeing the RSL club’s entertainment and in-house audio-visual systems was Paul Glover. Paul approached Integrated Audio Solutions with a specification and direction that succinctly outlined the club’s present and future requirements.

System Design Brief

Foremost in the initial specification was the need for the audio system to have a smooth coverage for a seated audience of 110 patrons. This meant no sub-extensions as the larger acts brought in their own PA requirements. Underpinning this requisite was the need to have an operating system that was both logical and easy to use, with little or no technical input or guesswork required, to bring the very best out of the installed ‘small house’ componentry. The installed system also needed to be as resilient as possible so as to accommodate the inevitable technology changes likely to occur in the future.

Audio System

To resolve the primary needs outlined in the brief Integrated Audio Solutions’s Kostas Psorakis had the hall rendered in CAD in order to position the house speakers to optimise and precisely match the acoustic performance of the audio system.

The fundamental system brief, coupled with Integrated Audio Solution’s CAD predictions, drove the imperative to install two full-range 12” speakers that could handle the RSL’s demanding performance expectations. To meet these demands the Electro-voice TX1122 was selected. These speakers come highly regarded for the exceptional sound quality at high levels, extreme sensitivity (for bodied low level background playback) and high-power handling.

The system electronics driving the TX1122’s were then housed by Integrated Audio Solutions in a durable and purpose-built equipment rack. The amplification heart was delivered via the new Dynacord L2800 FDI series DSP amplifier. This distinctive and well respected amplifier has fully integrated speaker processing with FIR - Drive Technology allowing fully optimised component correction. This feature makes for a sonically great speaker and offers complete speaker component protection.

Wireless Microphones

The wireless microphone of choice for the Semaphore project were two Electro-Voice R 300 HD Handhelds. These robust, all-metal, cost-effective radio microphone receiver / transmitter units come with excellent gain-before-feedback qualities.

Dual-Roll System

The Semaphore / Port Adelaide RSL also required their new speaker system to be dual purpose and be portable enough to use at the occasional foreshore event. The pool room system centres on a pair of Electro-voice ELX200 12P self-powered 12 inch speakers. The EV’s were chosen for their efficient Class-D power amplifiers and matched high-sensitivity transducers, allowing for excellent balanced body, even at low levels. The high-powered and lightweight compact enclosures can very easily be detached from the installed wall pole mount brackets and utilised as a mobile system for the occasional foreshore events.

At the completion of the update, the Semaphore is now a more accomodating space with a flexible audio solution that suits the functional and entertainment needs of the Adelaide RSL. The integration of Bosch and Dynacord products simplified the upgrade and Integrated Audio Solutions have seamlessly addressed the RSL’s present and future requirements.
