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.
Soundfield Equipment Pack Lists i-ceilings Soundfield Packs are supplied with the loudspeakers and infrared equipment in separate boxes. Before going to site please check you have all the items required. Detailed below are the contents lists for each of the various packs that are available...
Optional Soundfield Equipment • IS-20A Standard Infrared Sensor (For use with Soundfield Packs A, B, C, F & G) • IS-30A Optional Ceiling Mounted IR Sensor (For use with Soundfield Packs A, B, C, F & G) • Ext.
Infrared Wireless Microphone Technology 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.
Outreach Input Plates For use with Pack A, B, C only: A maximum of 5 Outreach Plates can be used with the i-ceilings amplified Sound Panel. 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.
Sound Panel Loudspeaker Installation Infrared remote sensor 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).
Conventional Wall Speaker Positioning 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. • Diagram 2.1 - wall speaker Position 1 • Diagram 2.2 - wall speaker Position 2 Above are examples of typical loudspeaker locations for the classroom environment. Please see page 13 for loudspeaker wiring options.
‘AMP’ i-ceilings SoundPanels Introduction: ‘AMP’ versions of i-ceilings Sound Panels feature a 20W power amplifier pre-installed on the 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 Connection Details Sound Panel ‘AMP’ Connection Details: (refer to Diagram 3 on page 11) • Line In: Balanced line level input terminals for connection of up to five remote Outreach Input plates (APA/APL, etc). • Mic Rcvr In: Unbalanced microphone level input terminals for connection of a Chiayo IWR-220 infrared wireless microphone receiver. It is also possible to use this input to connect Chiayo RF radio microphone receivers. Contact CIE-Group Technical Support (0115 977 0075) for advice.

IRX2 Wallmounting Soundfield System The IRX2s unit is a wallmount system featuring 50 + 50W amplifier and in-built infrared receiver, developed specifically for Soundfield systems using conventional wallmount loudspeakers or the i-ceilings CS4500 surface-mount Sound Panel (Soundfield Packs F and G). It has been designed to be both user-friendly in the classroom, whilst ensuring complete safety and security in such a welfare-critical environment.
Diagram 4 The IRX Kit 2 (Pack F) is supplied with 4 x Loudspeakers These can be installed in a number of ways depending on the size of environment and application required.
Testing and Commissioning Packs A, B, C, F & G: Before testing the system, ensure that all the batteries required for the transmitters are fully charged. After checking all the connections and wiring, set the line and Mic level controls to the half way point then connect the unit to the mains supply.
Setting the Transmitter(s) IWM-402 Pendant Transmitter: Remove the rear battery cover from the unit and insert a fully charged battery, ensuring the correct polarity, if you don’t have any fully charged batteries to hand use Hi capacity AA cell for testing/set up purposes.
Setting the Transmitters Checking the infrared coverage: When the transmitters and detectors used on the installation have been set, check the infrared coverage in the teaching space or training room. Whilst the infrared is, in theory, line of site it readily reflects off many surfaces (emitting power has also increased significantly in line with improvements in LED technology).

‘SoundField’ or a ‘SoundField Voice Reinforcement System’ is essentially the integration of a ‘mini-PA system’ in the classroom. Under quiet classroom conditions, most teachers have enough natural volume in their voice to communicate effectively with a standard sized class. However, a number of acoustic factors (lively/noisy classes, reverberant room conditions, ambient noise from equipment outside, hearing difficulties, etc...
