2. Introduction 2. Introduction The latest addition to Tannoy’s extensive line of column loudspeakers, VLS Series introduces another proprietary Tannoy innovation: FAST™ (Focussed Asymmetrical Shaping Technology). By combining transducer technology from the acclaimed QFlex Series with an innovative new passive crossover design, FAST provides exceptional acoustical benefits, including an asymmetrical vertical dispersion pattern which gently shapes acoustical coverage toward the lower quadrant of the vertical axis. The VLS Series comprises three models. The VLS 7 (7 × 3.5” LF) is designed for speech-only applications while VLS 15 (7 × 3.5” LF with 8 × 1” HF) and VLS 30 (14 × 3.5” LF and 16 × 1” HF) are designed for more demanding full-range music applications as well as speech. All are IP65 rated for dust and water ingress, are resistant to salt spray and UV, and have been subjected to rigourous high/low operational temperature and humidity testing. The VLS 7 and 15 are EN54 certified for use in fire detection and fire alarm systems. The loudspeakers are suitable for both indoor applications (house of worship, retail malls, auditoria) as well as covered outdoor use (transport hubs, concourses). Easy mounting is facilitated via supplied wall and flying brackets, with an optional pan-tilt bracket available. Aided by an addition of an exclusive Tannoy edition of EASE Focus v2.0 software, consultants can design systems with predictable results and also specify VLS Series in conjunction with Tannoy’s existing column loudspeakers – including I Series and QFlex – within the familiar environs of an industry standard software wizard. VLS Series loudspeakers can easily be switched from low-impedance mode (6 ohms for VLS 30, 12 ohms for VLS 7 and VLS 15) to 70/100 V distributed line operation. For quick and simple commissioning, this selection is made (along with the transformer tapping options) via a single rotary switch located on the rear termination. For applications requiring extended low frequency enhancement, a range of Tannoy sub-bass systems are available for use in conjunction with the VLS Series. 3. Unpacking Each Tannoy VLS Series loudspeaker is carefully tested and inspected prior to shipment. After unpacking, please inspect for any exterior physical damage, and save the carton and any relevant packaging materials in case the loudspeaker again requires packing and shipping. In the event that damage has been sustained in transit, please notify your dealer and the shipping carrier immediately. VLS Series Operation Manual rev 1.1.0... -
Page 5: Selection Of Operating Mode
4. Selection of operating mode 4. Selection of operating mode All VLS Series models can be operated as either a low-impedance loudspeaker or within a 70/100 V distributed system. The operation mode is selectable via a single switch located on the rear of the cabinet. Low-impedance mode is recommended if the cable runs are relatively short and the number of speakers is small. If, on the other hand, the cable runs are long and more than a few loudspeakers are required, then a distributed line system is ideal. When operating in low-impedance mode, the loudspeaker is able to deliver a wider frequency and dynamic range. However, if the cable runs are excessively long, then the sound quality may be compromised due to the increase in cable resistance and the resulting power losses. To keep the load to the amplifier manageable, it is also recommended that a small number of speakers be used, thus avoiding complex series/parallel combinations. When a large number of speakers are installed over long cable runs, it is recommended that a distributed (70/100 V) system be used. For distributed line, the cable need not have as large a cross sectional area as for low-impedance, resulting in savings in cable cost. All speakers are placed in parallel with the output of the amplifier, allowing easy installation. The wattage tappings can be individually adjusted, giving more flexibility within an installation.

Page 6: Wiring And Connections
5. Wiring and connections 5. Wiring and connections 5.1 Connector type Each VLS Series loudspeaker is equipped with a pair of internally paralleled barrier strip terminals for connection to the amplifier (or to other loudspeakers in a 70/100 V system or series/parallel configuration). Barrier strips accept wire up to 4 mm sq CSA (AWG 12). Barrier strip polarity is as indicated. 5.2 Low-impedance mode If connecting directly to the amplifier in low-impedance mode, connect the positive (+) conductor to a positive (+) barrier strip terminal and the negative (-) conductor to a negative (-) terminal. Several loudspeakers may be connected to one amplifier output in parallel, series, or series/parallel configurations using the other internally paralleled barrier strip connector. Please refer to following section on series/parallel configuration before connecting. When choosing cable type, it is important to select the correct cross sectional area in relation to the cable length and the load impedance. A small cross sectional area will increase the cable’s series resistance, inducing power loss and response variations (damping factor). Connectors wired with 2.5 sq. mm (12 AWG) cable will satisfactory under normal conditions; with very long cable runs, the wire size should be increased. Please refer to the following table for guidance: Cable Run C.S.A.of Cable % Power dB loss into % Power dB loss into each resistance loss into... -
Page 7: Constant Voltage (70 /100 V) Mode
5. Wiring and connections is continually clipping. A high-powered amplifier running at less than 90% of output power generally sounds superior to a lower power amplifier running at 100%. An amplifier with insufficient drive capability will not allow the full performance or the loudspeaker to be realised. (See technical specifications section for recommended amplifier power.) When using amplifiers from different manufacturers in a single installation, make certain that all amplifiers have closely matched gains. (Variation should be less than +/- 0.5 dB.) This precaution is important to the overall system balance when only a single active crossover is being used with multiple cabinets. When possible, it is recommended that the same amplifiers be used throughout. Series/parallel connections - When running low-impedance loudspeakers in parallel, care must be taken not to allow the impedance to drop too low, as damage may be sustained by the amplifier. Most low impedance amplifiers will be able to handle loads of 2 ohms to 8 ohms. This means for example that when using an amplifier with 2 ohm load rating, up to three VLS 30 or six VLS 7/15 may be connected in parallel per output, although care should be taken as impedance varies with frequency and at some frequencies the impedance will drop to below 2 ohms. 5.3 Constant voltage (70 /100 V) Mode In constant voltage distributed systems, normally a number of loudspeakers are connected in parallel to a single amplifier output. Connect the positive (+) conductor from the amplifier or prior loudspeaker in the system to a positive (+) barrier strip terminal and the negative (-) conductor to a negative (-) terminal. The other parallel barrier strip is available for connecting additional loudspeakers. A multi-position rotary switch on the rear input panel selects either the low-impedance operating mode or the high-impedance modes (70 V or 100 V) with available transformer taps. When using VLS Series loudspeakers in distributed line systems, the transformer can be tapped with available power levels shown in the table below: 70 V 100 V 9.5 W 9.5 W 19 W 19 W 37.5 W 37.5 W... -

6. Polarity checking All transformer primaries should be connected in parallel to the output of the amplifier. The summed total power rating in watts of the selected tap settings for all connected loudspeakers must not exceed the total output power rating of the connected amplifier output channel in watts. It is recommended that a generous power safety margin (minimum 3 dB headroom) be maintained between the total loudspeaker power requirements and the amplifier output capacity to avoid continuous amplifier operation at full rated output. 5.4 Wiring for EN54 and outdoor applications A right angled water tight cable gland is supplied with the VLS 7 and 15 for use in outdoor applications (Fig.1). The VLS 30 has an input panel cover with rubber wiring grommet for use in outdoor applications (Fig.2). Before making connections, pass the wire(s) through the cable grand/rubber grommet. The input panel cover is secured to the cabinet using the four screws already inserted around the input. Fig.1 VLS 7 & VLS 15 Fig.2 VLS 30 6. Polarity checking Checking the polarity of the wiring before the speaker system is mounted or flown will help ensure satisfactory performance. If you do not have a pulse-based polarity checker, you may check LF units as follows: Connect two wires to the + and - terminals of a PP3 (9 V) battery. Apply the wire connected to the positive (+) terminal of the battery to the speaker cable leg which you believe to be connected the positive terminal of the speaker connector; likewise connect the negative (-) terminal of the battery to the negative terminal of the speaker. If you have wired it correctly, the LF drive unit will move forward. At this point, connect the positive (+) speaker lead to the + terminal on the amplifier and the negative (-) lead to the - terminal on the amplifier. However, if the LF driver moves backwards with the battery test, the input connections need to be inverted before connecting the amplifier. If problems are encountered, inspect the cable wiring. Note that different amplifier manufacturers may utilise different pin configurations and polarity conventions; if you are using amplifiers from... -

8. Mounting and flying 8.1 Asymmetrical pattern considerations VLS Series loudspeakers are designed with an asymmetrical vertical dispersion pattern, a feature which allows improved performance with simplified mounting in many applications. The vertical dispersion of the VLS 7 and VLS 15 is +6 / -22 degrees from acoustic center axis, while the pattern of the VLS 30 is +3 / -11 degrees from acoustic center axis. Please be aware of this feature when planning your installation. In many situations where conventional column loudspeakers would require substantial downward tilt, a VLS Series loudspeaker would require less tilt or even allow flush mounting, thus providing a simpler installation with improved visual aesthetics.
