Split Zone / Analog Volume Control (Option 1) One Keypad
In cases of split zones where more than one set of speakers are driven from the same Keypad (such as a
Reading nook off of the master bedroom) it is sometimes desirable to place a volume control in the split zone.
FIG. 20 shows the connections to a remote zone, and “Autoformer” volume control device. Inure that
impedance setting don’t fall below 4 Ohms.

It is not recommended to install more than 2 pair of speakers per zone.
If you are installing 2 pairs of speakers in a zone and the speakers are 8Ohms 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.
