SYSTEM REQUIREMENTS

QLight™ series passive loudspeaker enclosures require only one amplifier channel for correct operation, the frequency splitting between the low frequency driver and the high frequency driver being accomplished by the internal passive crossover network built into each enclosure. If subwoofer enclosures are used as part of a bi-amplified system in conjunction with QLight™ series 2-way enclosures to extend low frequency response, additional amplifier channels and external electronic crossovers will be required. The Turbosound LMS-D6 and LMS-4 digital loudspeaker management systems are recommended for this purpose, as well as other professional quality digital controllers.

Bi-amplified loudspeaker enclosures require the use of one amplifier channel per frequency band for correct operation. Frequency splitting between the low frequency driver, and the mid and high frequency section drivers is accomplished by an external electronic crossover; while frequency splitting between the mid frequency driver and the high frequency driver in 3-way models (TQ445) is handled by an internal passive crossover.

Dedicated subwoofer enclosures require an additional amplifier channel when used as part of an extended frequency system. Frequency splitting between it and a QLight™ series mid-high enclosure is accomplished by an external crossover. Turbosound digital loudspeaker management systems are recommended for this purpose.

Amplifier considerations

Turbosound speaker enclosures should be driven by high quality power amplifiers designed for true professional use. Such amplifiers will have balanced inputs, DC and RF fault protection, and well designed cooling systems for reliability. Turbosound power amplifiers such as the T-45 and T- 25 are recommended for this purpose.

The program power listed in the loudspeaker’s technical specification is the best guide to the size of amplifier required for general purpose applications. The amplifier should therefore be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at the loudspeaker’s stated nominal impedance. This approach allows sufficient headroom to generate good dynamic range.

RECOMMENDED AMPLIFIER POWER RATINGS:

The amplifier's rated r.m.s. continuous power output (20Hz – 20kHz, per channel) should be equal to the program power handling of the loudspeaker at its nominal impedance.

TQ series manual page 8

user manual

QLightseries

In general, the more powerful the amplifier, the better it will sound, provided that it is not driven into sustained clipping. It should be understood that overdriving an insufficiently powered amplifier is more likely to cause loudspeaker damage – the total energy in a heavily clipped signal is far higher than in an unclipped signal – than operating a more powerful amplifier within its ratings.

One loudspeaker management system can be used to feed several amplifiers as long as all the amplifiers are the same (or have the same gain ratings). More than one loudspeaker management system may be required if the amplifiers are of different gain or type. Please contact your dealer if you require help in this area.

Equalisation

QLight™ series enclosures are designed to provide smooth and even frequency response. They do not need excessive amounts of external equalisation to overcome the sonic deficiencies often found in many lesser designs.

Should an extended frequency response be required at more than moderate sound pressure levels, the use of complementary Turbosound subwoofer enclosures is strongly recommended.

In order to compensate for the room acoustics, Qlight™ series enclosures require only minimal equalisation. As in any system, over-equalisation introduces phase shifts, distortion and a reduction in headroom, usually causing more problems than it cures. Under most circumstances a 1/3 or 1/2 octave graphic equaliser will generally be adequate, with the fader settings applied smoothly and as little as possible for the required room compensation. Most rooms will have resonances that will be excited at particular frequencies needing some cut to help tame the sound. These problems are most pronounced at the lower frequencies where loudspeakers generally exhibit very little directional control. If you find that the system needs a lot of boost at lower frequencies you may need additional sub-bass units. It is good practice to use as little equalisation as possible, aiming to cut frequencies rather than adding large amounts of boost.

Dispersion

Qlight™ series loudspeakers fall broadly into two categories of dispersion pattern: wide and medium. While a wide horizontal coverage pattern of approximately 80° to 100° is appropriate for a majority of small to medium venues, one of the design features of the TQ-445 is a tightly controlled 60º horizontal by 40º vertical dispersion pattern at mid and high frequencies. This gives many user advantages and eases placement decisions, being essentially a point and shoot system. The more focused directivity results in greater projection capabilities, making the TQ-445 very suitable for theatre and small auditorium applications. Remember that a 60º horizontal polar pattern equals an angle of 30º either side of the centre line at which the sound pressure level is

TQ series manual page 9

QLightseries

6dB down with respect to centre, (averaged over the whole frequency range of the loudspeaker).

Converging Elliptical Waveguide

A design feature of the TQ-308, TQ-310 and TQ-315 is the Converging Elliptical Waveguide(CEW), available in two directivity patterns: 100° x 60° and 80° x 50°. This gives many user advantages. The comparatively short flare length allows the HF and LF components to be physically aligned in the cabinet, so ensuring coherent arrival at the listener’s ear irrespective of distance from the loudspeaker. The elliptical format shapes the wavefront smoothly, and eliminates reflections in the throat area. Additionally this design does not suffer from the distortion typical of horns employing diffraction edges.

The waveguides can be removed and rotated through 90º in the cabinet, which allows the products to be installed in either vertical or horizontal formats while retaining the required coverage.

To rotate the horn, first remove the grille by undoing the countersunk Allen head screws which retain the grille from the sides of the cabinets. Remove the four screws holding the horn flange in place. Lift the horn and driver assembly out, rotate it through 90º and replace the fixing screws. Replace the grille.

MOUNTING AND FIXING

Rigging Hardware

A versatile range of mounting hardware is available that allows enclosures to be used in a variety of ways, in either mobile applications or permanent installations.

A top hat stand type fitting is fitted to the base of QLight™ series full range and mid-high cabinets for use with 35mm diameter loudspeaker stands. A pole mount socket is also fitted to the top of the QLight™ sub-bass cabinets. This allows two enclosures to be used together as an extended frequency range system as shown here with the TQ-445 mounted above the TQ-425 on the optional 35mm diameter straight pole. This enables a minimum footprint for the system and ensures the correct vertical distance between cabinets.

Internal M10 threaded rigging points are provided in several locations on the cabinet – generally on the top, bottom, sides and back – enabling enclosures to be suspended quickly and inexpensively using optional M10 shoulder eyebolts.

Downward inclination of the enclosure can be adjusted using an additional rigging point on the rear of the cabinet. Note: these rigging points are intended to hang a single box only and must NOT be used to rig a second enclosure in a vertical column.

TQ series manual page 11

RT-767 ring type flying points. Rigging points are provided on the top and rear of the TQ-310 and TQ-315 for use with optional RT-767 rings, enabling cabinets to be rigged in permanent installations and for mobile applications. Downward inclination of the enclosure can be adjusted using the third RT-767 rigging point on the rear of the cabinet

Swivel brackets provide a means of wall mounting some QLight™ series enclosures (TQ-308, TQ310 and TQ-315) in a horizontal or vertical orientation. They are attached to the box using the integral pole mount fitting at the bottom and the M8 internal rigging point on the top of the cabinet. For applications requiring a horizontal format, an additional scaffold clamp assembly can be used with swivel brackets for attaching to lighting grids.

Wall brackets are available for most Qlight™ series enclosures in different load ranges according to the weight of the cabinet. Two examples are shown below: the WB-10 wall bracket with a TQ230 and the WB-20A with a TQ-310. Wall brackets can be dis-assembled to simplify installation and are supplied with the necessary fixings (except wall fixings). Remove the countersunk screws in the back of the box that correspond to the bolt hole pattern in the speaker plate, and attach it using the bolts provided with the hardware. Mount the wall plate in the desired position using suitable wall fixings. Locate the captive bolt on the speaker plate in the hole provided on the wall plate, position and angle the loudspeaker for optimum room coverage and tighten the nylock nuts.

Side-mounted flying strips can be fitted to the sides of TQ-445 enclosures by removing the countersunk bolts on the top and sides of the cabinet and replacing them with the M10 bolts supplied with the hardware. Two flying strips are required for each enclosure; one attached to each side. This method offers a simple and cost effective way of flying single enclosures in permanent installations. Enclosures may also be arranged in a vertical column by coupling the flying strips together using QL-75 quicklinks or shackles. Turbosound flying strips are individually load tested. When used in this way the load is taken through the flying strips rather than through the woodwork of the enclosure.

Side-mounted flying strips can be fitted to the sides of Qlight™ series subwoofer cabinets to enable subwoofer enclosures to be flown as part of a permanent installation. Two different lengths of flying strips are optionally available for flying the enclosure in either a vertical or horizontal orientation. These are fitted by removing the countersunk bolts on the top and sides of the cabinet and replacing them with the M10 bolts provided with the hardware. Two flying strips are required for each enclosure. This method offers a simple and cost effective method of flying single or multiple enclosures, with the load being taken through the steel strips rather than through the woodwork of the enclosure. Enclosures may be arranged in a vertical column if required by coupling the flying strips together using QL-75 quicklinks or shackles. Turbosound flying strips are load tested.

WARNING: Rigging eyebolts must not be used for flying this enclosure. You must use the optional Turbosound steel flying strips described above.

Single point mount options include a universal FB-12 flybar assembly for use with the TQ-445 and this enables the use of several different fixing methods. The illustration at right shows the FB-12 with three different methods of suspending the TQ-445 cabinet: a unilock fitting; a scaffold clamp; and a pick-up point adapter.

To attach the flybar first remove the threaded plastic plugs filling the rigging points on the top of the cabinet. Fit the flybar to the cabinet using the captive M10 shoulder eyebolts supplied with the flybar assembly. There are 12 attachment points equally spaced along the length of the spine of the flybar. Depending on which point is chosen for the given attachment system, a wide range of downward inclination angles can be achieved over a range of approximately 70 degrees. The design of the flybar even allows for upward angles, for example for coverage of balconies that are higher than the loudspeaker location.

The FB-12 flybar assembly comes supplied with a U-6 Unilock fitting,

which provides a single attachment point. The point at which the Unilock is attached to the flybar determines the vertical angle of the loudspeaker as shown in the table following.

A pick-up point adapter offers a further single attachment point. This option provides fast adjustment of vertical angle. The point at which the eyebolt adapter is attached to the flybar determines the vertical angle of the loudspeaker as shown in the table following.

An aluminium scaffold clamp is attached to the fly bar by means of a simple clevis coupler. It is designed to rotate horizontally through 360° in order to enable accurate positioning of the loudspeaker. The point at which the scaffold clamp is attached to the fly bar determines the vertical angle of the loudspeaker as shown in the table following.

Permanent installations

Any installation, whether temporary or permanent, must be securely attached to the structure of the building using chain, steel wires or web straps which are certified and load rated for the purpose. The combined weight of the sound system, its cables and the rigging system must be safely carried by the points at which attachment is made to the building or structure. Great care must be taken in selecting the attachment points and methods, being absolutely sure of the load carrying capacity of points chosen.

NOTE: The rigging of loudspeaker systems is an extremely serious matter with potentially lethal consequences should anything go wrong. It is of vital importance that you, or other people rigging

TQ series manual page 17

the system, are suitably qualified to do so and have a full understanding of all the factors involved with safety as a number one priority. Turbosound accepts no responsibility for any accident, damage or failure of any rigged system. This rigging information is specifically related to the requirements of Qlight™ series enclosures only. For more detailed information on the whole topic of rigging various handbooks are available. If you are in any doubt contact your Turbosound dealer who will be able to refer you to an experienced rigging company.

Choosing the best location

When using any QLight™ system, certain room parameters will affect the resultant sound quality and coverage. For example, any boundary like a wall or floor will lift certain frequencies. If you are placing the unit in a corner then a lift at the bass end is to be expected and it may sound rather boomy. This can be compensated for moving the speaker or cutting low frequencies with a graphic equaliser.

When speakers are flown in free space then boundary effects are minimised. The result is a smooth frequency response without any boost at odd frequencies, but the bass end may appear subjectively light. In this case increase the sub-bass level to bring the low end up.

The relationship between sound pressure level and distance is an “inverse square law” so remember that every time the distance from the sound source is doubled the sound level decreases by 6dB. For every 3dB increase of speaker output you need a doubling of input power and you can work out the wattage input needed to give the required SPL levels at various distances from the loudspeaker(s).
