9 OPERATING & SERVICING
It is the responsibility of the user to ensure the loudspeaker is used within its operational capabilities in order to
avoid damage. Damage to a loudspeaker or the onset of damage is normally easy to detect – you can hear it.
Normal causes of loudspeaker failure can be attributed to the following:-
1. Amplifier Clipping (Normally associated with using an underpowered amplifier)
2. Voltage levels being applied to the speaker which is in excess of the recommended programme power.
3. Mechanical noise coming from the speaker (i.e. over excursion)
4. High levels of distortion
DO NOT drive any of your electronic equipment into clipping, particularly the power amplifiers.
Avoid sustained microphone feedback.
Avoid extreme boosts on equalizers and DSP loudspeaker management systems as these can cause excessive
input to the drivers at the boosted frequencies. Generally, cutting frequencies is preferred to correct for frequency
response problems. This will keep power levels within a predictable amount.
Tannoy VQ loudspeakers are capable of levels that can permanently damage hearing.
Take precautions so that audiences are not exposed to such levels (in excess of 100dBA). Due to the very low
distortion content from these loudspeakers, they may be producing SPL levels well in excess of what you think
they are. It is advisable to monitor the levels with an SPL meter.
