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. 29 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.
