Introduction:

The IAPA (Integrated Armstrong Panel Ampli

fi

 er) 

consists of a 20W power ampli

fi

 er pre-installed on 

an Armstrong i-ceilings Sound Panel. Sound Panels 
can be supplied with a wide range of ceiling 

fi

 nishes 

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 ampli

fi

 er 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 ampli

fi

 er 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 

fi

 tted 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.
