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. It maintains correct impedance matching between the amplifier and the
speakers by the use of instant setting S1, S4 and S8 jumpers on the control. This eliminates the need for
separate impedance matching components in multi-room installations.
Fig. 1 The 760-00
SPECIFICATIONS:
Type:
2 channel TRI-FI™ wound precision autoformers, with independent grounds.
Terminals:
Eight plug-in type screw terminals.
Power Rating:
25 Watts continuous, 150 Watts peak.
Freq.Response: 20-20,000 Hz ± 1dB at 1 watt.
Attenuation:
11 steps at 3 to 6 dB per step - 35 dB max. (Max. CCW position is OFF).
S1 setting:
0 dB @ Max. CW (pass-through position).
S4 setting:
9 dB @ Max. CW.
S8 setting:
13 dB @ Max. CW.
Impedance:
S1 setting: Pass-through position. i.e. 8 Ohms on OUTPUT reflects 8 Ohms to INPUT
(Max. CW position).
S4 setting:
8 Ohms on OUTPUT reflects 32 Ohms to INPUT . Likewise, 4 Ohms on OUTPUT reflects
16 Ohms to INPUT (Max. CW position).
S8 setting:
8 Ohms on OUTPUT reflects 64 Ohms to INPUT. Likewise, 4 Ohms on OUTPUT reflects
32 Ohms to INPUT (Max. CW position).
Mounting:
Fits most new construction junction boxes - uses single space.
Note: Will not fit certain retro-fit boxes, such as the Carlon 14 and 25 cu. inch series. Be
sure to check fit before choosing J-boxes!
Dimensions:
1-5/8" W x 2-7/8" H x 2-5/16" D

INSTALLATION 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. It maintains correct impedance matching between the amplifier and the speakers by the use of instant setting S1, S4 and S8 jumpers on the control. - Page 2 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. Right Channel Jumper Right Channel Jumper Positions I N P U T...
- Page 3 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.
- Page 4 5. Next, calculate the overall paralleled impedance with the following formulae: = 1 ÷ [(1÷Z ) + (1÷Z ) + (1÷Z ...etc.)] = overall paralleled impedance = 1st paralleled group after S setting = 2nd paralleled group after S setting = additional paralleled groups, when used.
- Page 5 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. The plug-in connectors and the printed circuit board of the 760-00 are marked with the terminal identifications.
- Page 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. CAUTION: THE ELECTRICAL JUNCTION BOX, IN WHICH THE 760-00 IS MOUNTED, MUST BE DEDICATED TO LOW VOLTAGE A/V SYSTEM APPLICATIONS.
