5. For optimum performance, loosely place one piece of standard fiberglass insulation, cut to fit the joist size,
above the speaker and extending about 15" or more beyond the speaker; For taller joists, also place
fiberglass insulation against the joists on either side of the mounting hole.
Turn your amplifier/receiver OFF before performing any connection steps, in order to prevent
accidental damage to your amplifier.
If you plan to use multiple speakers per amplifier channel. The minimum impedance of ONE Invisa
in-wall/in-ceiling speaker is 4 ohms per channel.
6. Pull the speaker wire out of the hole and connect the speaker as follows:
• Your Invisa HTR 7000/8000 speakers are equipped with a set of high-quality push spring connectors that
can be used with bare wire. Make sure all wires are firmly fastened. Always use high quality speaker
wire of the correct rating (see above) and sufficient gauge for the distances you are running (see your
dealer for assistance).
• Strip 1 / " (12 mm) of insulation from each of the two conductors to expose the metal, twist the
2
strands of each into a single un-frayed strand.
• Hold the speaker up to the cutout and connect the speaker cable.
Proper polarity (or phase) is critical for proper stereo imaging and
bass performance. Connect the red(+) terminal of your receiver
or amplifier to the red(+) terminal of the Invisa loudspeaker and
the black(-) terminal of your receiver or amplifier to the black(-)
terminal of the Invisa loudspeaker (See Figure 3). Most speaker
cables are either color coded or have some indicator (ribbing
or writing) on one of the conductors to help maintain this consistent
polarity. It is essential that all
speakers be connected in the
same way (in phase) to its own
channel of the amplifier. If you
experience a great lack of bass,
it is likely that one speaker is out
of phase(+ and – reversed) with
the other.
• Push down on the top of the speaker's push terminal to reveal the wire hole in the post. Insert the wire
into the hole and release your pressure on the terminal.
