Once again DJ friends I turned to the English Precision Devices loudspeaker manufacturers of the big sound club's original Heavy duty 24 inch PD2450 system, permitting me to tinker about with the numerous environmental Thiele-Small Parameters characteristic flexibilities and minuscule limitations of RMS power handling, that is typically found lurking in the various time honored traditional design enclosure formats. I know from years of experience work with pa that this is a top choice driver for a well established serious quadraphonic chamber design blueprint and not a pile of ugly old rubbish.
To date I have not commandeer an opportunity to showcase this new PD2450 and PD2150 precision devices range. This was first tested today, with the loud speaker placement design audio schematics and sound engineered by me and the stage roadies with the aim to improve on the original systems performance taking it way past the extreme. This assigned dj hire system not only mirrors a venue's ionic excellence but harmoniously complements it’s a clean modern design with Embossed metallic blue silver stucco aluminium sheet speakers. Full disco flitebag finish with the interior aerodynamic in shape implementing an inconsequential harmonic distortion and have been ergonomically designed to become an integral feature of the different venues of Pinoy music Tagalog disco folk concerts. Living in a Philippine residential area lot it’s difficult to run the disco speaker bass sound twenty four hours to give it a full testing.
The main system for the dance area of the club mobile rig upgrade comprises four extra stacks of quad PD2450 and a new enhancement to seven-way active crossover system but just still two-way on surround channels. Crossing seven ways active I know what some of you are thinking decolonization but is you have a signal generator two good perception akg vocal microphones matched pair of C 451 B and a Hameg HM806 oscilloscope. The fazing and appropriated signal delays can be implemented across the full frequency ranges but it’s a nightmare to work out the ultimate EQ. The other new units made up of four PD2150 this recent re-launch is centered on quality of system to ensure that the Philippine Disco bass rumble continues its reputation for sonic excellence, keeping its roots firmly within Dance Music culture and underground traditions.
Apart from the fresh new cutting-edge Sub-bass 24 inch Speaker enclosures there has been some reconfigurations to the mid-high range box enclosures, each new stack is controlled by a BSS FDS366 Omnidrive Compact Plus and powered by four Ecler DPA 4000T /bridge mode and two Ecler DPA 2500T rugged amplifiers for each PD2150 cab. Led Technics SL1210 decks and a Ghost Soundcraft D-Mix 1000 DJ mixer together with passive and active monitors, Yamaha hs80m monitor completes the hiring ensembles. The outdoor disco marquee tent a mellowing out Lounge room with soft-pedal ambient lighting Showtec Galaxy Centre Piece as the top attraction and with supporting haze from a Showtec show fog 800, this is where a more charming intimate environment is going to be required by the party punters. It will features two stacks each of the two housing PD1850 precision devices Disco bass and sound enhanced hid-tops JBL and peavey compression drivers with the same combination of control, amplification, front end and monitoring as the primary output. Why a Ecler DPA 4000T amp for each of the 16 24 inch PD2450 cones, because the bandpass is filter well into the roll off specifications at 16.5 Hz and 31 Hz. I understand that you can't hear most of that but as wacko jacko would say can you feel it. I yet to have done a full analysis to find out the transfer loads for the different frequencies from 11 Hz to 40 Hz. If at 11Hz the wattage is very low IE less then 800 watts RMS a cone I will make a hybrid between a filter and a step up transformer to obtain full thrust at the 16.5 Hz, with good quality capacitors and coils so even though you won’t hear it I still don’t want any colouring of the signal.
To take full advantage of BSS's PC based Soundbench control software, the main dance arena and chilling out music marquee systems, along with the PD powerful precision system installed have been linked by RS485 multi-drop data connections and line audio feeds to a patch bay in a convenient quiet location out of sight not to obstruct the live production. This allows real-time control of Omnidrive parameters from any of the 1210 Technics djing turntables positions or from the patch bay, meaning any of the working DJ positions can drop a feed into any or all of the venues amp racks, and also providing simple access for outside broadcast and recording applications. This setup is very similar to having a second Mackie DFX or Ghost LE 32 Soundcraft mixing deck for Asian folk dance bands live culture nights, just a better flexibility all round.
The new 96 kHz sample rate Omnidrives were chosen for the system controllers because of their superior audio performance and flexibility of operation. Equipped with the latest generation of 24 bit A/D converters, and with carefully engineered support electronics these units provide a dynamic range of over 112dB (unweighted) without applying massaging techniques that could have nasty side effects. The disco speaker sound enclosures were specially modified to take account of the different unique acoustic environments, with additional damping material being added to the quad sound 24 inch bass bandpass subwoofer boxes and folding scoop horn loaded 21 and 18 inch bass bins low mid and Richard Allen drivers with custom cone rewound to my spec mid horns.
Special attention has also been given to loudspeaker placement for the high tec DJ box by careful arraying of the exploding sound units. Subtle delays are used to focus the centre of acoustic attention mid-way between the custom DJ consoles and wall front stacks. This has the additional advantage of protecting the 1210 Technics decks from the full brunt of the sub-bass minimizing the risk of acoustic feedback, and enhancing the effect, of the 3D dynamic stereo sound image as you move from the garden chill tent down into the outside main arena dance floor. This rig is only now lacking Tiesto, Carl Cox and John Digweed to put it through its paces.
We are striving to uphold the best mobile sound Philippine club's eclectic music policy, this is enough to put any hire sound system to the test but following these latest improvements to the sound rigs facilities, we can confirm that it's looking and sounding better than ever. Next on the agenda is the subject of acquiring larger trilite 200 truss framing extensions to the mobile club dancefloor space and this will be used also in the chill out area.
