Connecting Speakers - Integra RDA-7 Instruction Manual

Connecting speakers

Before connecting the speakers, place them correctly by consulting the instruction manuals that came with them.
Also, read on page 11.
For surround playback, the configuration and placement of your speakers are very important.
Phasing your speaker system
If the speakers are not correctly connected, the phasing
may be reversed. The result is an audio output with a
strange feeling and indistinct positioning of the sound
source.
To obtain an accurate bass response, all channels must
be connected in-phase. When the tone of a single note
is output, if the speakers are in-phase, the speakers will
vibrate in unison. If the speakers are properly connected
in-phase, then the positioning (of the instrument, singer,
etc.) becomes clear. And if they are out of phase, then
the positioning becomes unclear for a sound space with
a strange feeling.
If this is the case, first check if the speaker cables are
connected properly. The cables can usually be told
apart by the colors, by different markings, or by colored
lines on the cables. Use these marking to make sure that
for each channel the red binding posts (+) on the RDA-7
are connected to the (+) terminals on the speakers and
the black binding posts (–) on the RDA-7 are connected
to the (–) terminals on the speakers.
• When you are using only
one speaker or when you
wish to listen to monaural
(mono) sound, a single
speaker should never be
connected in parallel to
both the right and left-
c h a n n e l
simultaneously.

Speaker ratings
In actuality, you can connect any type of speaker to the
RDA-7 and it will operate. The RDA-7 can operate low-
impedance speakers with Power levels that exceed
optimum levels with no problem. With many of the
speakers that are nominally rated with an impedance
of 4 ohms, their impedance may lower down to 2 ohms
within a specific frequency range. You should not
experience any problems at these low impedances
unless you demand excessively high volume levels.
Since the output performance of the RDA-7 is extremely
high, it is vital that the maximum ratings for the input
Power of the speaker system be checked. To avoid
damage to the speakers, the Power ratings for the
speakers must be equal to or greater than the output
Power rating (4 ohms) of the RDA-7 for the
corresponding impedance.
Caution
We will not be held responsible for any damage that
may occur to your speaker systems or other
components that result from the use of a speaker system
with ratings that are lower than those of the RDA-7.
