Forum Installation ™ Installation of Ceiling Sensor (ICS-55) The ideal mounting location is in the center of the room's ceiling. The ideal installation is flush mounted on a white, reflective ceiling like the acoustic drop-down style. This will ensure 360º coverage and will minimize the transmission distance for more reliable performance. - Page 10 Forum Installation ™ Connection of speakers The IMA-232 has two channels of amplified audio, rated for a minimum 4-ohm speaker load (two 8-ohm speakers each). There is a blue Phoenix speaker connector on the back panel labeled “R” & “L”. However, the amplifier produces monoaural sound, so it does not matter what speakers are connected to what channel so long as no more than 2 x 8-ohm speakers are wired in parallel.
