Controlling 3 zones with 1 FreeSpace IZA 2120-HZ amplifier

Andrew ·
I have three rooms which will require a ceiling speaker (e.g. FreeSpace DS 40F) and a wall volume controller (e.g. ControlCenter CC-1 zone controller) in each room. Will I be able to use one FreeSpace IZA 2120-HZ amplifier in this setup? Or are there any other recommendations that will allow three rooms to have a speaker and volume controller in each? Thanks in advance, Andrew.

As Arno said, mono channel driving of 70/100v lines are detected as open lines. However, the amp will still function correctly, and to avoid your client reporting errors you can configure the amp not to trigger alarms for open circuits. Right click the amp in project view, "Setup alarms".

Hi Luis, You probably connect 100/70V loudspeakers to a single channel. What you select in the properties window is when will the fault output (on the rear of the PowerMatch) contact be triggered. This is independent of what the PowerMatch will detect. Because you have a high impedance using 100/70V loudspeaker, the PowerMatch will "see" this as an open line. BR Arno

The IZA2120-HZ is a 2 zone amplifier. If 3 zones are required a second IZA2120 / ZA 2120HZ or IZA / ZA 190-HZ (depending on the required power) is required. Or you can used 100V attenuators instead of the CC-1 as long as you do not need to change input source per zone. You can also have a look at our 4 channel amplifiers like the PowerShare and our new PowerSpace line. BR Arno
