1 Speakers & Volume Controls INST ALLA TION INSTRUCTIONS 760-00 MATCH MAKER™ SPEAKER VOLUME CONTROL The Model 760-00 is an in-wall mountable stereo speaker volume control with impedance matching capability. From one to sixteen pairs of stereo speakers may be driven from one stereo power amplifier, using an equal number of 760's.
2 760-00 SETTING THE IMPEDANCE MATCHING JUMPERS Fig. 2 shows the location of the pins and the jumper locations on the pins for the three impedance multiplier positions. To set the jumpers correctly, refer to Fig. 2 and the charts and procedures that follow.
3 Speakers & Volume Controls 760-00 3. On the 3rd row, opposite "8 OHMS" and below "3", note the letters "S8". These signify the required impedance multiplier. 4. The two jumpers therefore, one for each channel, need to be plugged onto the S8 pins on each 760 in each room.
4 5. Next, calculate the overall paralleled impedance with the following formulae: Z O = 1 ÷ [(1 ÷ Z 1 ) + (1 ÷ Z 2 ) + (1 ÷ Z N ...etc.)] Z O = overall paralleled impedance Z 1 = 1st paralleled group after S setting Z 2 = 2nd paralleled group after S setting Z N = additional paralleled groups, when used.
5 Speakers & Volume Controls Fig. 3. A Typical 3-Room System INSTALLATION As shown in Fig. 3 , 4-conductor speaker wire (two wires for each channel) is connected from each of the 760's to the power amplifier (home run from each room). Also, each channel (left and right) requires a pair of wires from the 760 to the speakers.
6 The metal mounting plate of the 760-00 is attached to wall J-boxes using the two 6-32 pan-head screws supplied. See Fig. 4 . Slots are provided in the metal bracket so that adjustments can be made in the alignment of the 760.
