686-10
Power Interruption Status
The 686-10 should normally be plugged into an unswitched AC outlet. However, if the power to the 686-
10 is interrupted by a power failure or other reason, the internal memory will retain the last selected
switched status for each of the speaker relays.
INSTALLATION
Fig. 3 shows a typical application of a 686-10 in a multiroom system. The amplifier and speakers are
connected to the Model 686-10 by the four-terminal plug-in connectors.
The order of the stereo speaker pairs used is not important. If you have only two pair of speakers connected
to positions 5 and 6, they will work just as well as they would connected to positions 1 and 2.
The PROTECTION RESISTOR switch connects a four-Ohm resistor IN and OUT of a series connection with
the amplifier. The purpose of the resistor is to prevent loading the amplifier with less than four Ohms with
any combination of speakers. Since the 686-10 connects speakers in parallel, anytime two or more pair
of speakers are active the impedance would be less than four Ohms (a typical "eight-Ohm" speaker usually
has an actual impedance of less than eight Ohms somewhere between 20 Hz and 20 kHz). When all six
pair of eight-ohm speakers are active and the protection resistor is switched OUT, the parallel impedance
is less than 1-1/3 Ohms. With the resistor switched IN, the impedance will be less than 5-1/3 Ohms but
always more than four Ohms.
