user manual TA-880 INTRODUCTION Turbosound Aspect System Concepts The TA-880 system is a modular point source loudspeaker system designed to deliver extremely high fidelity audio. The system is easily scaleable from large and medium scale ground-stacked and flown concert touring down to small clubs and events. The Aspect system concept centres around the exceptional directivity of the patented Polyhorn™ devices employed in the high frequency and high-mid frequency sections of the mid/high enclosure.
user manual TA-880 The Aspect Polyhorn™ Concept The patented Polyhorn™ design effectively solves the problem of the tendency for exponential horns to beam with increasing frequency. Dividing the multi-cellular horn into multiple tapered waveguides guarantees that the path length of each micro-horn is equal from the surface of the driver diaphragm to the horn mouth, and ensures that all frequencies from all parts of the diaphragm arrive at the horn mouth together.
user manual TA-880 Aspect TA-880 Turnkey System Concept Aspect is available as an integrated audio system package, comprising loudspeakers with integral flying hardware, amplifier racks and all necessary drive and control equipment in an extremely compact and manageable form. In addition, the system has been designed to truck pack efficiently and handle easily.
user manual TA-880 The Loudspeaker Management System (LMS) Concept Turbosound Loudspeaker Management Systems are more than just electronic crossovers. As well as steep slope active filters and high performance limiters, they provide full digital alignment of all components in the Aspect enclosures, to ensure a coherent acoustic output. They also incorporates a number of features which contribute to overall system reliability and ease of setting-up and use.
user manual TA-880 Power Amplifiers In addition to the Turbosound T-25 and T-45 model amplifiers supplied with turnkey Aspect systems, the following other power amplifier brands provide sufficient performance and mechanical compatibility to perform well with Aspect loudspeaker systems: • MC2 E series • Lab Gruppen FP series • Crest Pro series • QSC Powerlight II series Digital Controllers In addition to the Turbosound LMS-D6 and LMS-D26 loudspeaker management systems, the following digital crossov
user manual TA-880 TA-880L Low Frequency Enclosure The TA-880L low frequency enclosure covers the low frequency range from 40Hz up to 100Hz. It contains two very high power 15" neodymium drive units loaded with TurboBass™ devices. The TA-880L is a very compact enclosure and its minimal size and low weight ensures easy handling. It is designed to provide beneficial low frequency coupling when used in multiples. The enclosure is designed to be groundstacked.
user manual TA-880 The Polyhorn™ and TurboMid™ devices are unique to Turbosound and are covered by principle patents world-wide. They utilise specialised forms of horn loading which provide exceptionally low distortion and high efficiency from cone-type drive units. The subjective effect of these devices is greater clarity and transparency of reproduction when compared with conventional compression drivers and horns.
user manual TA-880 Transportation An optional WB-880H wheelboard is available which clips on to the front of the TA-880H cabinet, allowing single units to be conveniently transported. These are designed to be stackable, so that when not in use they can be neatly stored without taking up unecessary floor space. TA-880L bass cabinets are fitted with heavy duty wheels. Optional heavy duty transit covers are available for TA-880H cabinets.
user manual TA-880 Aspect trapezoidal Flying System To take full advantage of the very precise dispersion properties of the Aspect system, an external rigging system has been developed. The flying systems are inherently safe, flexible and simple to use.
user manual TA-880 FLYING AND STACKING Overview The Aspect system flying hardware is specifically designed to take advantage of the precise horizontal directivity characteristics, as well as allow a wide range of adjustment of the vertical angles between adjacent enclosures, and the overall vertical inclination of each column of enclosures. This means that arrays can easily be optimised to suit the coverage requirements of any situation.
user manual TA-880 GIGMATE™ ACOUSTIC SIMULATION While the Aspect System is remarkably intuitive in terms of building arrays and aiming them, and requires no theoretical calculations in order to achieve optimum coverage of a room or audience space due to its inherent ‘point-and-shoot’ nature, there may well be situations where some prior knowledge of a venue can save time in setting up and configuring the PA.
user manual TA-880 The screen is split into four main areas: System Setup The left hand side of the screen is where you define the system, auditorium and project. Tabs On the bottom of this window allow you to toggle between modes. Mapping Properties This is the main window which will display the system as configured in the System Setup window along with the audience areas and mappings.
user manual TA-880 Designing a system To design a system begin by defining the venue/audience areas by clicking on the “Audience Area” tab in the bottom left of the screen. Within this window you can edit or remove existing audience areas, and create new ones. There are two methods of defining an audience area. In either case you must define the X1/Y1 coordinate of the start of the area, you can then either enter the X2/Y2 points or its length and angle.
user manual TA-880 Now select the number of cabinets deep that you wish to hang or stack in the “Box Count” dropdown. Trim height, or PA wing height can now be set in the “Position” field. If a mix of Low and High cabinets are to be used then select in the Cabinet window the type and location in the array of each box. The angle between cabinets can now be set in the “Angle” list. Each cabinet has an aiming line that can be used to determine the centre of each cabinet’s dispersion.
user manual TA-880 Now that the general design has been established the system performance must be mapped. At the top of the main window there is an “SPL Mapping” checkbox. This will map the system output at the frequency and bandwidth selected in the adjacent dropdown boxes. For most applications a 3 octave mapping gives realistic and useful data.
user manual TA-880 The Audience Area graph at the bottom of the window shows the SPL, as specified in the SPL Mapping lists, on the selected Audience Area. The selected area is highlighted in the main window and the graph is repeated onto op each area, Selecting the “Combined Level View” tab will show the SPL across all areas simultaneously. Now that the system is mapped the intercabinet angles or row attenuation may be trimmed to provide the smoothest coverage.
user manual TA-880 Safety Notes on Rigging The Turbosound TA-880 system has been designed and constructed to a high standard of safety, and tested to the most demanding of specifications with a safety factor of 13:1. Always wear protective headwear, footwear and eye protection in accordance with local regulations.

user manual TA-880 FLYING HARDWARE The Aspect TA-880 flying system consists as follows: • Flying swords and safety lynch-pins – support a single cabinet. • Flying chains – link the top row to flybars. • Twin bar – supports two vertical columns.
user manual TA-880 Vertical Coverage Vertical coverage is dictated by the physical dimensions of the room and the location of the audience spaces. The number of boxes required in a vertical column is therefore determined by a number of factors including the trim height of the cluster, the vertical coverage you are trying to achieve, and the distance or projection required.

user manual TA-880 Flying Chains Flying chains are available in two lengths. FC-880 CHOKED CHAIN ASSEMBLY FC-880S SHORT CHAIN ASSEMBLY The FC-880S flying chain is a short chain designed for linking the top row (or single row) of cabinets to the flybar. It consists of a top hook, chain, connex connector and dagger. The dagger is provided with a single hole for attachment inside the cabinet’s sword box using a safety linch pin.
user manual TA-880 Flying Swords Three types of flying sword are available: • SW-880H swords are used to fly TA-880H mid/high enclosures. • SW-880HM swords are used to fly TA-880HM high-mid enclosures. • SW-880LM swords are used to fly TA-880LM low-mid enclosures. SW-880H FLYING SWORD SW-880HM FLYING SWORD B B A A SW-880LM FLYING SWORD Flying swords are fabricated from steel and are provided with two locating holes at each end, and these allow for a range of vertical inter-cabinet angles.
user manual TA-880 Tilting Strap 0.59m 4m The TS-890 tilting strap is in two parts. The longer part is attached to the tilt strap point on the flying bar using the buckle at its end. The other part of the strap with the ratchet is hooked into the tilt strap point on the rear of the bottom enclosure. The free end is then threaded through the ratchet and the strap tightened to achieve the desired tilt.
user manual TA-880 Flying a single TA-880 trapezoidal cabinet using M10 eyebolts The simplest method of flying a TA-880H cabinet is with a pair of M10 shoulder eyebolts on the top, using a third eyebolt on the rear of the cabinet to tilt the cabinet. 1. Remove the two countersunk M10 screws located just behind the sword slots in the top of the cabinet. 2. Replace these with M10 shoulder eyebolts with a minimum thread length of 20mm (3/4”) 3.
user manual TA-880 Flying a single TA-880 trapezoidal cabinet using FC-880 chains A single cabinet can be flown using a pair of FC-880S short chains and daggers. These simply pass through slots in the top of the cabinet and are secured with safety linch-pins inside the handle boxes. Connect FC-880S short flying chains to the appropriate suspension tabs on the flybar and check that the daggers line up with the slots. In the diagrams below only one dagger is shown for clarity. 1.
user manual TA-880 Flying a vertical column of TA-880 trapezoidal cabinets When flying more than one cabinet deep you will need to use SW-880H swords to suspend and correctly position the second and subsequent cabinets. These make use of the internal sword boxes in the trapezoidal cabinet in the same way as the flying chain and dagger, and ensure that the entire weight of the column is taken through the metalwork and not through the woodwork of the cabinet.
user manual TA-880 3. Position the second cabinet directly underneath the first. Fit a BS-780 biscuit into the top kelping braket of the lower cabinet to keep the backs of the boxes and act as the hinge. Lower the top cabinet and feed the swords into the sword boxes. Make sure that the biscuit engages into the bottom kelping bracket slot of the upper cabinet. The lower end of the swords will be visible through the handle boxes of the lower cabinet. 4.
user manual TA-880 Flying swords are provided with two holes ast each end. This allows for a choice of four incremental vertical angles depending on which hole the linch-pin is located in, and which will determine the combined vertical coverage of the column.
user manual TA-880 Flying a cluster of TA-880 trapezoidal cabinets Aspect trapezoidal flybar configurations offer two basic configurations for assembling arrays, two-wide and three-wide. These configurations will cover the majority of applications, providing up to a maximum 75° of horizontal coverage. For more complex installations or touring applications multiple flybars can be used in a modular fashion.

user manual TA-880 Tight-packed Flying Assemblies When flying single rows of cabinets, especially in installed applications, it is a good idea to configure the boxes in a tight-packed arrangement in order to achieve high power density in a small space. Modular coupling kits are available in two-wide and three-wide configurations in order to facilitate tight-packed flown clusters.
user manual TA-880 The MC-880/3 Modular Coupling Kit consists of three top straps which attach to the box with M10 hex bolts (supplied) and two rear strap with fixes to the rear of the cabinet. These parts when combined hold the cabinets firmly together and they can now be picked up as a single block.
user manual TA-880 Bass Enclosure arraying Aspect bass enclosures are most efficient when ground stacked in a block. Not only do they benefit from improved coupling when there are no air gaps between them, but they also couple to the ground. However, some of this energy may be absorbed by nearby obstructions such as barriers or a tightly-packed standing audience. Sound pressure levels may also be excessive for members of the audience if they are able to get too close to the enclosures.
user manual TA-880 Ground stacking In many situations, indoors or outdoors, it is desirable to ground-stack the system. In this case, the same general rules apply as for flown arrays. High packs should be kept well above head-height and angled carefully for even coverage. A three-wide stack of TA-880H cabinets supported by four TA-880L bass cabinets as pictured below provides an ideal configuration for many situations, giving 75° of horizontal coverage and standing just under 2 metres high.

user manual TA-880 Mechanical Installation When supplied as part of the AMP-890.2 system rack, the amplifiers are pre-installed. If an amplifier is removed from the rack for any reason, it is important to re-install it correctly. The amplifiers must be supported at the front and rear, as originally supplied. Failure to support it adequately may eventually result in vibration-induced metal fatigue of the rack mounting ears and such damage will not be covered by the warranty.
user manual TA-880 Voltage Setting Your models will be set up at the factory for correct operation on your local voltage supply. No further adjustment is necessary. Voltage Range The minimum supply voltage over which the amplifier will operate is 180V for the 220-240V range, and 90V for the 110-120V range. Naturally, maximum power output will be reduced accordingly from the published ratings.
user manual TA-880 The amplifiers are designed to operate with fully balanced equipment. Ground loops or loss of performance may be experienced if connected to unbalanced sources. If it is unavoidable, however, the following wiring convention should be used.
user manual TA-880 Setting higher gain does not change the maximum available power but changes the level of signal input to achieve maximum power. In any case, provided that the input signal is less than 20dBu/7.7V, the built in limiter circuit will prevent distortion within the amplifier. The gain should be set to match the signal from the source, e.g. mixer, controller, or equaliser.
user manual TA-880 Long Speaker Lines Whenever loudspeakers are connected to power amplifiers by long cables (above 20'/6m), there is invariably an increased risk of high frequency instability. It is aggravated by the combination of RF pickup in unshielded cables acting as aerials, and multiple complex reactances in the cable and loudspeakers.
