Driving Multiple Speakers From a Single RAT1

In some cases you may need to drive more than one set of speakers from a single RAT1, such as in large rooms or adjoining areas where common volume operation is acceptable. A typical system is shown in Fig. 6.

1.Use the same charts and rules for setting the impedance jumpers. In Fig. 6, all 8-Ohm speakers and an amplifier capable of handling an impedance of 4-Ohms, is assumed; resulting in a jumper setting of S1.

2.Note that two MIRV1's are used; one at one location in the room and the 2nd in another, for convenience of use. They both control the same volume level and track each other.
