4.1. Connectors & Cabling for Low Impedance Operation
The i9 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 wire with an outside diameter of up to 15mm and a current rating
of 30 Amps. The pins of the 2 Speakon sockets identified input/output on the rear of the
input panel are paralleled within the enclosure. Tannoy have adopted the conventional
wiring standard for the i9 product :-
Pin 1+ is Positive
Pin 1- is Negative
