1. Also available with a built in THP 60 low insertion loss transformer the 7 T provides a more dynamic performance with greater bandwidth than other 70 100V line systems For applications requiring extended low frequency enhancement a range of Tannoy sub bass systems are available and can be used in conjunction with the 7 2 Unpacking Every Tannoy i7 product is carefully inspected before packing After unpacking your loudspeakers 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 3 Connectors Cabling The iZ has two screw terminals for connection to the amplifier these are gold plated in order to improve electrical conductivity and to prevent oxidisation These terminals are capable of accepting cables with a conductor diameter of up to mm Red is Positive Black is Negative 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 5mm 12 gauge cable This will be perfectly satisfactory under normal conditions In the case of very long cable runs the wire size should2.

7. city Care should be taken to avoid running the amplifier into clip clipping is the end result of overdriving any amplifier Damage to the loudspeaker will be sustained if the amplifier is driven into clip for any extended period of time Headroom of at least 3dB should be allowed When evaluating an amplifier it is important to take into account its behaviour under low impedance load conditions A loudspeaker system is highly reactive and with transient signals it can require more current than the nominal impedance would indicate Generally a higher power amplifier running free of distortion will do less damage to the loudspeaker than a lower power amplifier continually clipping It is also worth remembering that a high powered amplifier running at less than 90 of output power generally sounds a lot better than a lower power amplifier running at 100 An amplifier with insufficient drive capability will not allow the full performance of the loudspeaker to be realised It is important when using different manufacturers amplifiers in a single installation that the 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 compressor limiter or active crossover is being used with multiple cabinets it is therefore recommended that the same amplifiers be used throughout 6 Power Selection i7T Determine the maximum power in watts needed at each speake
