The Turbosound TFL (Floodlight) loudspeaker system can be used on its own as a side or front fill, as well as being part of the Turbosound Flashlight System. The Turbosound TFL-... -

(or 24 bass and 24 mid-highs) will provide a formidable system for distant audience coverage in large arenas, and can be integrated with Turbosound Floodlight enclosures for short and medium range coverage. This set of components also forms a standard building block for the construction of spherical arrays. -
Page 6: Tfl-760H
760H is used to augment Flashlight systems where certain sections of a venue dictate wider coverage and shorter throw. The TFL-760H also makes an excellent flown or ground stacked stage side fill system due to its tight vertical coverage. TFS-780 user manual Page 6... -

Page 15: Setting Vertical Angles
Setting Vertical Angles Vertical connection between enclosures and to the flying bars is achieved using the Q-D Flying Plate and D-ring system originally developed for Turbosound's TMS-3 flying systems. However, instead of fixed-length steel connections, an adjustable length chain is used. -
Page 16: Arraying
TFS-780 Arraying The concept of arraying the TFS-780 Flashlight system is to create part of the surface of a sphere. A small part of a large sphere will form a high-directivity (long-throw) system with a high SPL at a distance, whereas a large part of a small sphere will be of lower directivity producing less SPL at a distance, but having a wider angle of coverage. -

Note: the outer holes on the flybar are the pickup points; the inner holes are the safety points. Take time to get the flypoints positioned accurately, as it is much easier to do it now than later when the flybar is under load.

Also adding some curvature to the stack will help to increase the directivity of the stack especially in the higher frequencies. Turbosound Flashlight bass bins can be stacked in various configurations, each giving a certain emphasis which can be used to great advantage dependent on the room, situation and type of music. - Page 24 Tall, thin bass stacks work best, preferably in blocks of eight bins high by two wide. When space permits use two of these blocks, the onstage block flush with and parallel to the stage, with a second identical offstage block slightly separated from the first and angled outwards by 10 .

In most applications the upper rows of a cluster of cabinets will cover the more distant sections of the audience, and the vertical intercabinet angles will therefore be progressively smaller towards the top of the cluster.

The internal memory automatically saves all settings when the unit is switched off, so there is no need to re-load delay and temperature information every time the system is powered- up. The memory contents are retained indefinitely without the need for an internal backup battery. TFS-780 user manual Page 30... -

D6 provides and maintains the optimum signal delay between the HF and HMF drivers and the LMF driver in the TFS-780H when the unit is switched to Flashlight mode, and in Floodlight mode the three drivers in the TFL-760H are physically aligned so inter-driver time delays are switched out.

This start-up phase lasts for only a few seconds, after which the output drive ramps up to its previously selected level, dependent on the input rotary encoder settings. The pause allows you time to (re) mute the channels to silence the outputs if desired. TFS-780 user manual Page 41... -

Pin 3 cold (-) The shield connection to pin 1 at each amplifier input must be maintained under all circumstances, as TURBOSOUND will not be responsible for consequential damage arising to loudspeakers, etc., should this connection not be made. Polarity In accordance with international standards, TMC amplifiers are supplied with Pin 2 hot (+), so a positive (+V) input gives a positive (+V) output from the red (+) output terminals. -

The metering responds in 5mS and holds for about half a second, so every audibly significant peak is visible.

90°C. If this happens, the output of that channel is reduced by 3dB and you will notice that the TEMP LED is illuminated. If no further action is taken, the amplifier’s output will be muted, and the TEMP LED will remain lit. TFS-780 user manual Page 46... -

Voltage and Current Certain life-threatening faults cause the amplifier power supply to Voltage and Current Voltage and Current immediately latch off ('Latched Kill'). The TEMP LED then flashes. Should this occur, check for the following: Mains voltage outside limits. Internal amplifier fault or failure. TFS-780 user manual Page 47... -
Page 48: Troubleshooting
Check the drive level. It is almost certainly driving the amplifier into hard clip (>0dB). For immediate powering-up, temporarily reduce the input signal (the front panel controls are fine for this). You can trim the level once powering-up is successfully accomplished. TFS-780 user manual Page 48... - Page 49 In this case attention should be given to optimising the entire system's gain structure. If a loud hiss persists when the input cables are disconnected, contact your TURBOSOUND dealer for advice. Hum is nearly always caused by grounding faults, errors and peculiarities. Because the AMP- 780 rack and LMS-D6 have been designed to be hum-free as a complete system, the search must be directed at the interconnecting cables or the preceding equipment.

To clean the copper heatsinks, either use an airline to blast the dust out, or in the event of severe contamination with residues from cracked oil smoke machines, an ultrasonic cleaning bath filled with a suitable solvent (refer to TURBOSOUND LTD for advice, as an incorrect solvent could cause irreparable damage to the electronics). -
