Introduction; Unpacking; Connectors/Cabling - Tannoy i8 User Manual

1. Introduction

Designed for a wide variety of sound reinforcement applications the Tannoy i8 is an
ultra compact loudspeaker system capable of delivering high sound pressure levels
with extremely low distortion, resulting in outstanding clarity, definition and detail.
The i8 comprises one 8 inch (205mm) Dual Concentric driver in which the low
frequency (LF) and high frequency (HF) sources are coincidentally aligned to a point
source, resulting in a smooth uniform frequency response over a wide area of
coverage. The sophisticated CAD designed waveguide combines 60 degree conical
dispersion and excellent acoustic impedance characteristics.
Designed primarily for fixed installations, the i8 is constructed from medium density
fibreboard (MDF), for a high level of acoustic damping. The cabinet does however
feature a blanking plate which if removed will accommodate a 35mm pole mount.
Four M8 inserts on the back of the i8 allow the speaker to be mounted vertically or
horizontally when used with the CUB8 bracket.
For applications requiring extended low frequency enhancement, a range of Tannoy
sub-bass systems are available and can be used in conjunction with the i8.

2. Unpacking

Every Tannoy i8 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 i8 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 6mm.
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 wire size should exceed this, refer to the following table for guidance:-
Red is Positive
Black is Negative
