3. ZONE8 ZONE 16 PA VA system design rules with IDA4SW a Audio output Channel and Zone allocation In switching application you must be aware that the 8 zones of an IDA4SU are connected to a single audio output Consequently only 1 announcement can be made at a time Audio routing is done at the channel level and zone switching occurs only after if the audio source has the required priority Then if a new source with a higher priority takes the control of an audio channel its zone level routing will replace the current switching state You must consider this when allocating audio channels and zones in your system Zones which can potentially be addressed by different sources at the same time must be placed on different audio channels Note that IDA4SW is very flexible It is not compulsory to fill all channels with 8 zones and you can connect any number of IDA4SU Moreover you still have the possibility to put a single zone with its own amplifier on a free channel without using an IDA4SU For example you can build a 14 zones system with 2 IDA4SU on 1 IDA4SW 5 zones on channel 1 8 zones on channel 2 and 1 zone on channel 3 b Impedance error tolerance constraint In switching application with up to 8 lines on the same amplifier you can have a lot of loudspeakers in parallel Detecting a cut line defect on only 1 line is therefore far more difficult because the error on this single
