Russound SP550.2 - Manual (Page 10)

If your other speakers are rated at 4-ohms, some amplifiers may experience difficulty driving both 4-ohm sets at once
and shut off intermittently when the volume control is turned up. In this case, you should operate only one set of
speakers at a time or keep the volume extremely low.
Another option is to purchase a speaker selector such as the Russound SS4 & SS6 series or a PRO series speaker
selector. These are designed to maintain impedance control allowing your amplifier to work efficiently.
INSTALLING RUSSOUND SPEAKERS DURING NEW CONSTRUCTION
Needless to say, installing In-Wall speakers when a house is being built is far easier than doing it later.
Russound offers a ‘Speaker Rough-In Kit”. The Rough-In kit is designed to provide the drywall installers the cut-out
for the In-Walls. The kit comes with two brackets, one for the left speaker and another for the right. The brackets are
nailed/screwed onto the wall studs. Once the house/room is completed, you can install the speaker (more on this
below).
During new installation, keep the following tips in mind:
•Use a small level to verify that the mounting frame is straight.
•The flat brackets and nails which attach the speakers are thin enough that they won’t interfere with wallboard
added later.
•If possible, run speaker wires after AC wiring is in place to avoid induced hum caused by close parallel proximity.
•Secure speaker wires in place along the run with insulated staples only and be careful not to pierce the insulation.
Allow a bit of slack for expansion of building materials.
•The actual speakers should not be installed until the wall board is in place. In the meantime, leave several feet of
wire coiled up and secured to the back side of the mounting frame.
•When it comes time to put up the dry wall, make sure the speaker cut-out hole doesn’t extend farther than 1/4”
from the sides of the mounting frame.
•After the wallboard is put up, install the speakers as detailed on pages 5 of this manual.
