1. Introduction

Thank You for purchasing Tannoy PowerDual™ iQ 10.
The iQ 10 has been designed for live and fixed installation music and speech sound

reinfo

rcement applications. They are specifically designed for use in venues,
theatres, arenas and distributed systems in stadiums. The iQ 10 can be used both
indoors and out due to its durable “skeletonised” plastic weatherproof enclosu re.

The iQ 10 utilises a point source 10” PowerDual™ driver utili

sing the unique Funktion
One Research engineered and patented Axhead™ technology, which provides a
controlled 60° × 40° (H × V) dispersion, covering a frequency range from 180Hz to
18kHz. For low frequencies, the iQ 10 has been designed to operate in conjunction
with the iQ 18B sub-woofer, where overall system balance is achieved by using the
TDX1 or TDX2 system controller, with provision for the relevant cross-over
frequencies, delays, gains, high and low pass filters and parametric EQ amongst
other features.

Tannoy’s, iQ 10 is a weatherproof skeletal desi

gn suitable for use both indoors and
out, where the compact and lightweight unit allows for flying into tight corners. The iQ
10 has two Speakon™ connectors for ease of installation. An optional plywood
cabinet is also available to match the iQ 18B profile where they can be flown together
using additional hardware for flying.

The iQ10 comes in 4 variants:­iQ 10 - Skeletal iQ 10 Configured for Bi amp operation.
iQ 10P - Skeletal iQ 10 with internal passive crossover.
iQ 10C - iQ 10 Configured for Bi amp operation in plywood cabinet.
iQ 10PC - iQ 10 with internal passive crossover in plywood cabinet.

2. Unpacking

Every Tannoy iQ10 is carefully tested and inspected before packing. After unpacking,
plea

se inspect your iQ10 for any damage sustained during transit. In the unlikely
event of any damage, would you please notify your dealer immediately and retain
your shipping carton, as your dealer may ask the faulty unit to be returned for
inspection.

3. Connectors/Cabling

The iQ 10 is fitted with two 4-pole Speakon™ connectors. Speakon™ has the
followin

g advantages over EP and XLR type connectors: All terminations are
solderless, making 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 15 mm
and a current rating of 30 Amps.

The pins of the Speakon™ sockets, marked input/

output on the rear of the speaker,

are paralleled within the enclosure.
Tannoy has adopted the following wiring standard for iQ 10: -

Cable choice consists mainly of selecting the corre

ct 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 p

erfectly 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: -

4. Amplification & Power Handling

As with all professional loudspeaker systems, the power ha

ndling is a function of
voice coil thermal capacity. 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 loud

speaker 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 they have very clo

sely 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.

5. Operation

For optimal performance, the iQ 10 has been de

signed to operate in conjunction with
the Tannoy TDX1 & TDX2 System Controllers, and iQ 18B bass unit for extended
bass performance. The TDX controllers have been factory preset to provide the
recommended eq, crossover points, and overall system balance. Please refer to the
TDX1 & TDX2 manual for operation.

If you intend using an alternative loudspeaker m

anagement system (e.g. BSS™,

KlarkTeknik™, XTA™ etc) please refer to section 12 of this manual.

6. Equalisation
Over equalisation can reduce system headroom, and introduce phase distortion

resulting in greater problems than cures. If equalisation is required then it should be
applied gently and smoothly. Violent equalisation will be detrimental to the overall
sound quality.

7. Arraying
Comb filtering is a phenomenon, which cannot be cured by equalisation. Small

alterations to loudspeaker positions can have the effect of minimising problematic
combing frequencies. Arrays should be constructed so that the individual coverage
patters of each loudspeaker combine with minimal overlap. The design of the iQ 10C
cabinet greatly simplifies the creation of effective arrays, allowing seamless wide (120
degree) horizontal coverage using two loudspeakers without the need for tedious
experimentation.

By placing the iQ 10C cabinets as shown in the diagram below, minimal dispersion
pattern overlap is achieved, guaranteeing an extraordinarily smooth transition.

It is also possible to stack the cabinets vertically using the above method, say for use
in a central cluster, where greater vertical dispersion is required.

manual. The use of other accessories or non-approved methods of assembly may
result in an unsafe hardware system by reducing the load safety factor. Welding, or
any other method of permanently fixing hardware components together or to the
integral fixing points in the cabinet should never be used.

Whenever a Tannoy Professional loudspeaker is fixed to a surface using a Tannoy
Professional hardware device, the installer must ensure that the surface is capable of
safely and securely supporting the load. The hardware employed must be safely,
securely, and in accordance with the manual, attached both to the loudspeaker and
also to the surface in question, using only the fixing holes provided as standard and
covered in the manual. Secure fixings to the building structure are vital. Seek help
from architects, structural engineers or other specialists if in any doubt.

All loudspeakers flown in theatres, nightclubs, conference centre or other places of
work and entertainment must, be provided with an independent, correctly rated and
securely attached secondary safety – in addition to the principle hardware device.
This secondary safety must prevent the loudspeaker from dropping more than
150mm (6”) should the principle hardware device fail.

The iQ 10 & iQ 10P is supplied as a ‘skeletal’ design loudspeaker, which can be used
both indoors and out due to it’s weatherproof exterior. As it is compact and
lightweight, it can easily be flown into tight corners and small spaces. The iQ 10C &
iQ 10PC are built into plywood cabinets that match the profile of the iQ 18B sub bass
cabinet. If the iQ 10 is flown outdoors, please note the unit should be positioned such
that the Speakon™ connectors are facing downwards, to avoid excess moisture
leaking into the socket.

The following optional flying kit is available:

Skeletal Flying

The iQ 10 ‘skeletal’ enclosure include a yoke as standard. The unit can be flown from
a flying bar or relevant rigging via the flying loop, by utilising a Tannoy SECUR-ET
VPC hook clamp or equivalent.

The Tannoy iQ 10C & iQ 10PC loudspeakers can
be flown with high quality VEB M10 eyebolts with
collar to BS4278:1984. The loudspeakers are
equipped with internal steel braces, which also
double as the flying points, and accept VEB M10
eyebolts.

To install the VEB M10 eyebolts remove the
original M10 counter sunk screws from the
locations you wish to install the VEB M10
eyebolts. Then replace these counter sunk M10
screws with the VEB M10 eyebolts. The kelping
brackets on the rear of the cabinet should only
be used for tilting the loudspeaker to the desired
angle.

Important:

It is imperative for safety reasons
that two eyebolts linked to two independently
fixed straps are used per cabinet.
Never attempt to use formed eyebolts i.e.
formed from a steel rod and bent into an eye.

12. System Configurations & OEM Controllers
Passive or Biamp?

The iQ 10 is supplied as standard for bi-amp operation, therefore there is no internal
passive cro

ssover network between the mid & hf units. The Bi-amp controller

parameters below must be adhered to for optimum performance.

An optional iQ 10P (passive version) can be ordered if (part no. 8001 2210)
A loudspeaker driven in Biamp mode offers a number of performance advantages,

su

ch as increased system headroom. Audio program materiel is made up of many
different frequencies and harmonics. In music materiel, most of the energy is in the
low frequencies, with less in the highs. When both high and low frequencies are
present in a signal, the stronger low frequencies can use up amp power, leaving little
or no reserve for the highs, so they are more likely to cause the power amplifier to
clip. In a Biamp driven system, a smaller amp can handle high frequencies, LF amp
clipping is less of a factor, and less overall amplifier capacity is needed due to the
efficiency improvement in the absence of a passive crossover.
