Onkyo RDA-7.1 instruction manual Connecting speakers, Phasing your speaker system, Speaker ratings

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

Speaker ratings

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 binding posts (+) on the RDA-7.1 are connected to the (+) terminals on the speakers and the binding posts (–) on the RDA-7.1 are connected to the (–) terminals on the speakers.

•If you want to connect a single speaker, do not connect it to several terminals.

•Do not connect more than one cable to each speaker terminal. Doing so may damage the RDA-7.1.

•To prevent damage to circuitry, never short-circuit the positive (+) and negative (–) speaker wire.

In actuality, you can connect any type of speaker to the RDA-7.1 and it will operate. The RDA-7.1 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-7.1 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-7.1 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-7.1.
