Split Zone / Analog Volume Control
In cases of split zones where more than one set of speakers are driven from the same keypad, it is sometimes desirable to place a
volume control in the split zone. FIG. 35 shows the connections to a remote zone, and “Autoformer” volume control device.
Ensure the impedance setting doesn't fall below 4 Ohms.
If you are installing 2 pairs of speakers in a zone and the speakers are 8 Ohms, it is not necessary to use an impedance
matching autoformer type volume control. A standard stereo volume control will perform properly. The impedance will be
approximately 4 Ohms.
If you are using an impedance matching volume control with 2 pairs of speakers set the impedance matching to the 2X
setting.
NOTE:
It is not recommended to install more than 2 pair of speakers per zone.
