Amplifi er Considerations

The DCS subwoofers should be driven by high quality power amplifi ers designed for true professional use. Power amplifi ers should be capable of delivering long term
broadband power equal to half the loudspeaker's peak power rating at its stated nominal impedance. The use of underpowered amplifi ers must be avoided as heavily
clipped signals can cause permanent loudspeaker damage. Limiters, crossovers and equalisation points must be set in accordance with the settings provided on the
TANNOY website. This will ensure the optimum sound quality and long-term reliability as well as protection from damage.
Neutrik speakON* NL4 locking input connector(s) and 4-way barrier strip(s) are provided, allowing options for input and link, parallel and discrete operation.
