SYSTEM INSTALLATION GUIDE

i-ceilings Soundﬁeld Systems provide a complete

solution designed for use in teaching and training

environments. They utilise the latest speaker and

infrared technology to create sound reinforcement

systems which combine the highest levels of

performance and ﬂexibility with the minimum of visual

intrusion.

Please remember that Soundﬁeld is a ‘sound

reinforcement’ system, not a public address system;

levels should therefore be set accordingly.

Typical Classroom Coverage:

Please note: These infrared Soundﬁeld Systems are

designed for use in a typical standard sized classroom

(normally up to 60m²) and are not recommended for

use in large room applications such as school halls,

lecture theatres, sports halls, etc...

(For larger applications, we suggest using RF

wireless microphone systems).

The IR wireless microphones use direct/reﬂected light

emissions and, so, large non-reﬂective surfaces (light

absorbent surfaces such as black/dark painted walls

or large fabric coverage, etc...) in the classroom which

may reduce coverage must always be considered in

the system’s performance.

This manual is intended for use by installation engineers.

The separate user manual should be left with the user.

Infrared Wireless Microphone

Technology:

As the Systems use wireless infrared to transmit the user’s

voice, some understanding of how this operates is useful...

Infrared is simply invisible light and acts in a very similar way

to ordinary light, a useful feature in classroom applications.

For example, infrared recognises walls as boundaries so

multiple systems can be used without problems.

Whilst it is true that IR can be directional, all our emitters

use high power LED arrays and detectors are wide angle.

Infrared also readily reﬂects from walls, ceilings and windows

so full coverage is easily achievable. Frequency allocation

problems are eliminated and any transmitter can be used

with any receiver; as a result these systems are both easy

to commision and very ﬂexible in use.

Infrared Wireless Microphone Technology

AC Power Requirements:

Pack A, B, and C Systems:

A single 13 amp power point is all that is required

as all ancillary Soundﬁeld system items are powered

directly from the panel ampliﬁer. If two speakers are

required, a further slave Sound Panel (set to 8 ohms)

can be connected to the extension speaker terminals

of the Panel Amp (see page 10 for connection details).

Pack F & G Surface-mount Systems:

A single 13 amp power point is all that is required

as all ancillary items are powered from the IRX

Receiver/Ampliﬁer.

Cable Requirements:

Mains & Audio:

All mains supply cables (terminated with 13 amp UK plugs) are included with kits,

as are the interconnection cables between the infrared receiver and ampliﬁer.

Infrared Receiver and External Detectors:

Two ready-terminated 10 metre coaxial extension cables are provided for the

connection of the extension IS-20A infrared detectors. If required, these can be

extended to 20 metres by means of a further extension cable and male-to-male

coupler. (The Pack F System is supplied with 3 extension cables and a

male-to-male coupler). For distances of over 20 metres please consult

our technical support team.

A maximum of 5 Outreach Plates can be used with

the i-ceilings ampliﬁed Sound Panel or IRX Wallmount

Ampliﬁer. The APA/APL (supplied with the packs) is

intended to be used for the connection of a laptop,

CD, MP3 player (or similar audio signal) and should be

located in a convenient position near to the teaching

position.

Outreach Plates are active with balanced outputs

and, as such, can be daisy-chained together to

provide multiple inputs as required, each with its own

dedicated volume control. By this means it is possible

to provide a ﬂexible input structure to cater for almost

any conceivable requirement.

Low Level Output Plates (APA/LLO):

These optional units are intended to facilitate the

connection of individual hearing assistance systems

to the Soundﬁeld system. The plate is supplied with

a 3.5mm 2pole jack socket with an output level of

775volts nominal, set by means of a user adjustable

level control.

Cable requirements are as Outreach input plates, but

a separate cable must be provided where this facility

is installed.

All Outreach input and output plates require a single gang

socket box with a minimum depth of 25mm.

Outreach Input Plates

Outreach Plate connection cable specification:

The cable between the speaker panel, the ﬁrst and any following Outreach Plates must be to the following minimum

specification: 1 pair twisted and screened for audio, plus 1 additional pair for power. ‘West Penn’ 357 supplied by

CIE-Group, or any good quality quad microphone cable should be suitable.

A wide range of Outreach Plates to suit various other interface requirements is available; please call CIE-Group

for details.

• APA/APL Outreach Plate

for AV inputs

• APA/LLO Outreach Plate for

assistive hearing systems

Sound Panel Loudspeaker

positioning and installation

(Packs A, C & G):

In systems using only one i-ceilings Sound Panel,

the speaker unit should ideally be installed in the

ceiling grid slightly to the rear of the classroom

using the teaching position as a datum and as

near as possible to the centre line of the other axis

(see Diagram 1).

(Pack B):

When 2 panels are used, the exact positioning will

be dictated by the shape of the classroom but

the locations should be chosen to give the best

possible coverage.

Remote Infrared Sensor (IS-20A)

installation:

Two remote IR sensors are supplied with all kits.

These should be installed at either end of the

classroom just below ceiling level. Generally the

centre of the wall behind the teaching position and

the same position on the opposite wall will give the

best coverage (see Diagram1 above) (alternatively

position on opposite sides of the room).

The IS-20A is a 170 degree wide angle detector

and should be angled slightly downwards to give

the best possible coverage.

Sound Panel Loudspeaker Installation

Sound Panel Cabling:

Take care to route all cables in such a way that

they cannot rest on the rear of the Sound Panel.

When completing the installation be sure to ﬁt the

safety bonding wire to each speaker.

Finally check that no debris has been dropped

on the panel. Remove everything; you would be

amazed at the effect a 10mm cable off-cut can

produce!

Please ensure to make all connections before

switching on power to the amplifier supply.

Conventional Wall Speaker Positioning

Where FBT Project 315 Loudspeaker option is used (Pack F):

If possible, the 4 speakers should be installed in Position 1 as shown in

Diagram 2.1; if this is not possible then Position 2 shown in Diagram 2.2

can be used.

• Diagram 2.1 - FBT wall speaker Position 1 • Diagram 2.2 - FBT wall speaker Position 2

Before installation the rotary switch at the rear of the speakers must

be set to 8Ω. Do not attempt to run the speakers at higher power

settings/100v line as this will damage the ampliﬁer.

IRX Wallmount Amplifier/IR Receiver

When an Armstrong Sound Panel is used, the ampliﬁer is an integral part. It supplies

power to the IR receiver and any Outreach points as well as providing audio

inputs and controls; please refer to IAPA section for details on connection

and commissioning.

However, where surface-mount speakers (Pack F & G) are used, the IRX Wallmount

Ampliﬁer/IR Receiver is provided as part of the kit. It should be installed adjacent to the

whiteboard (or front of the classroom) at a height convenient to allow adjustment of the

level controls. The associated Outreach Plate should also be installed close by.

Please refer to page 12 for details of IRX installation and commissioning.

Safety Note

It is most important that the supplied safety cables and security clips are used and ﬁtted

correctly on each loudspeaker as part of the installation.

Introduction:

The IAPA (Integrated Armstrong Panel Ampliﬁer)

consists of a 20W power ampliﬁer pre-installed on

an Armstrong i-ceilings Sound Panel. Sound Panels

can be supplied with a wide range of ceiling ﬁnishes

allowing the unit to be installed in any Armstrong

suspended ceiling.

For advice on matching non-Armstrong suspended

ceilings, please contact the CIE-Group sales team.

IAPA Integrated Panel Amplifier

IAPA Features:

The IAPA ampliﬁer has two inputs; one is at line level

allowing the use of remote Outreach input plates such as the

APA/APL, the other input is at a level suitable for connection

to a Chiayo IWR220 (or similar infrared or RF wireless

microphone receiver). An 18v DC supply is available from

the ampliﬁer to drive the Outreach plates and a 15v DC

supply to power the IR receiver. Both inputs have their own

level controls.

An additional line level output, 18v DC supply and external

low impedance speaker output are also features of this

unit.

The unit is ﬁtted with ‘High’ and ‘Low’ tone controls to

allow adjustment of the frequency response of the panel.

The frequencies at which the controls operate have been

chosen to allow speech clarity to be optimised to the

acoustic environment.

All the connections to the unit are externally accessible and

are of the removable screw terminal type, allowing for quick

and easy connection.
