5. acking Every Tannoy VS15BP is carefully inspected before packing After unpacking your loudspeaker 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 notify your dealer immediately Connectors Cabling The VS15BP is fitted with 4 pole Neutrik Speakon connectors Speakon has the following advantages over EP and XLR type connectors All terminations are solderless this makes life easier at the time of installation or when field servicing is required Contacts will accept 6 sq mm wires with an outside diameter of up to 15mm and a current rating of 30 Amps The pins of the 2 Speakon sockets on the input panel are paralleled within the enclosure Tannoy has adopted the conventional wiring standard for the VS15BP product Pin 1 is Positive Pin 1 is Negative For a worldwide list of Neutrik distributors see http www neutrik com Cable choice consists mainly of selecting the correct cross sectional area in relation to the cable length and the load impedance A small cross sectional area would increase the cables series resistance inducing power loss and response variations damping factor Connectors should be wired with a minimum of 2 5 sq mm 12 gauge cable This will be perfectly satisfactory under normal conditions In the case of very long cable runs the wir

8. facturers amplifiers in a single installation that they have very closely matched gains the variation should be less than 0 5dB This precaution is important to the overall system balance when only a single active crossover is being used with multiple cabinets it is therefore recommended that the same amplifiers be used throughout Crossovers The VS15BP hos been designed to be used in conjunction with Tannoy controllers for optimum performance these provides specific crossover and equalisation functions for the V series combinations as well as combinations of other Tannoy products Of course the VS15BP is compatible with other OEM controllers crossovers For optimum performance please refer to the section on System Configurations amp OEM Controllers Equalisation Positioning The VS15BP is designed to need no equalisation or correction to overcome system limitations As a result it will only need equalisation to compensate for difficult acoustic environments Excess equalisation can reduce system headroom and introduce phase distortion resulting in greater problems than it cures If equalisation is required then it should be applied gently and smoothly Violent equalisation will be detrimental to the overall sound quality The frequency band over which a subwoofer operates is essentially omni directional therefore efficiency of the VS15BP may be further enhanced if the unit is placed against a wall where the radiation in the for
