User manual RUSSOUND TBL-75

[. . . ] Never use solid or aluminum electrical wire. When running speaker wires inside the walls, most states and municipalities in the U. S. specify that you must use a speaker cable with a minimum fire rating of "CL-2" or "CL-3" Consult your Russound dealer or electrician. Russound offers "CL-3" rated speaker cable, which is multi-stranded and enclosed in temperature -resistant PVC jackets specifically designed for this application. [. . . ] EXAMPLE: 8 speakers ÷ 4 pair of speakers = 2 system impedance. Determine the proper impedance-matching setting by dividing the amplifier impedance (step 1) by the system impedance (step 4). Note: if the resulting number is between 2 and 4, use X4; if it 3 is between 4 and 8, use X8; if it is greater than 8, reduce the number of pairs of speakers. EXAMPLE: 8 amplifier impedance ÷ 3 system impedance = 2. 7 impedance-matching switch setting. Because 2. 7 is between 2 and 4, use the X4 switch setting. X1 setting: Use this setting only when the TBL-75 volume control is used with an impedance-matching speaker selector. The X2, X4 and X8 settings are used when you are not using an impedancematching selector. Now that you have determined the proper switch settings, set all the volume controls in the system to the same setting (see diagrams opposite). IMPORTANT: If you are unsure of any of the installation procedures, the TBL-75 volume control should be installed by a professional custom installer. Strip 1/8" of insulation from the ends of all the wires that will be connected to the TBL-75 volume control. If necessary twist or solder the ends to keep from fraying and shorting to the other wires. CAUTION: Do not reverse the input and the output connections. Connect the leads from the amplifier or speaker selector to the connector labeled "input". The wires should stay consistent, left+ of the amplifier to the left+ input of the volume control, observing polarity and identification. As outlined in step #2, connect the speaker wires to the connector labeled "output". Make sure the amplifier or receiver is OFF and set the volume to minimum. Set the TBL-75 volume control to maximum (fully clockwise). If you are using a Russound speaker selector system, locate the On / Off button which corresponds to the speaker pair you wish to play. Turn on the amplifier or receiver and select a source such as a CD player. 4 L+ L- INPUT R- R+ Newmarket, NH U. S. A. X1 X2 X8 X4 L+ L- OUTPUT R- R+ MADE IN KOREA 5. Slowly turn up the amplifier or receiver volume and set it to a comfortable listening level. Be careful not to overdrive the amplifier. If the sound becomes distorted, you have reached the limit of the amplifier's volume capability and you should quickly reduce the volume to avoid damaging the amplifier. [. . . ] To return items for repairs, the unit must be shipped to Russound at the owner's expense, along with a written explanation of the nature of the service required. The unit must be packed in a corrugated container with at least 3 inches of resilient material to protect the unit from damage in transit. Russound reserves the right to request proof of purchase.
