Space Requirements & Impedance Matching

SPACE AND WALL REQUIREMENTS

SPACE REQUIREMENTS

Russound Advantage Iso-Mount speakers require a mini- mum wall depth of 3-5/8” (9.2 cm) (measured from the outside face of the mounting surface), and require at least 1.4 cubic feet of space behind the speaker for optimal performance.

WALL REQUIREMENTS

ACCEPTABLE INSTALLATION SITUATIONS:

•Any wallboard and 2x4 stud wall

•Lath and plaster wall

•Wood paneling and 2x4 stud wall. The dense, rigid nature of plasterboard (or lath and plaster) or thick wood paneling acts as a superb speaker baffle.

UNACCEPTABLE INSTALLATION SITUATIONS:

•Brick or concrete walls where the wallboard or panel- ing is attached to thin furring strips – This type of wall can’t provide proper depth (clearance) for the back of the Russound Advantage speakers.

•Locations concealing pipes, heating ducts and AC wiring – These elements can complicate speaker mounting and installation of speaker wire. AC wiring can induce hum caused by close proximity to the speaker.

IMPEDANCE MATCHING FOR AMPLIFIER AND SPEAKERS

Not all amplifiers or receivers can safely operate two sets of speakers at once. If you intend to run your Russound Advantage speakers and your main speakers concurrently, or if you intend to hook up and run two sets of speakers at the same time, it’s important to con- sider both the impedance of the speakers and the capa- bilities of the amplifier or receiver you’re using.

A speaker’s impedance rating indicates the amount of electrical resistance it places against current flowing from a receiver’s outputs. If the total speaker load does not present adequate resistance, the receiver increases its power output. Low-impedance speakers may hamper operations of receivers not designed to deliver large

amounts of current to low-impedance loads. This may lead to greater distortion, and causes the receiver to run hot or activate its protection circuitry.

First, consult the owner’s manual for your amplifier or receiver. It should state the minimum speaker imped- ance during multiple speaker operation. The impedance may also be printed on the back of the amplifier/receiv- er next to the speaker connectors. If you can’t readily determine this information, consult the dealer where you purchased the amplifier or receiver, or call the manufac- turer of the product in question.

The impedance rating for your Russound Advantage Music Series speakers is 8 ohms, 6 ohms for the Hi-Fi Series. Next, determine the impedance of your other speakers. It may be printed on the back of the speaker near the connection terminals, or you can consult the speaker’s owner’s manual. Speaker impedance must be equal to or higher than the amplifier/receiver speaker output impedance rating. For instance, an amplifier/receiver that is rated for two pair of 8 ohm speakers cannot support two pair of 4 ohm speakers.

If the amplifier/receiver is not rated for the speaker con- figuration desired, external volume controls and/or speaker selectors can maintain the impedance levels that will allow your amplifier/receiver to operate safely. Russound makes a complete line of these products, from Impedance-Matching Volume Controls to Impedance-Matching Speaker Selectors.
