Note: Do not connect more than two Powered Partners together in this manner. Acoustic Output Each loudspeaker system is capable of delivering peak sound pressure levels at 1m in excess of 109 dB (AC power supply). Placing the Speakers The AV570 speakers have been designed to provide a superior listening experience in a home environment. The following are some basic suggestions for achieving the best results from your new speakers. Power Requirements - AC Power Supply 120 volt version - 70 watts, 60 Hz; DC power supply: 9-25 volts, 14V nominal, 25V maximum. Amplifier Performance (AC Power Supply) 30 watts continuous per speaker, <0.5% total harmonic distortion, 40Hz-20kHz, >85 dB signal-to-noise ration (IHF A-network), 35 Watts dynamic power. · · Speakers should be placed near a wall, on a shelf, or on the floor. Orienting the speakers so they directly face the preferred listening area can have audible benefits in stereo imaging and depth of image. The amount the speakers are "toed in" for best performance should be determined by experimentation. For example, when the desired listening area is large relative to the distance from the speakers, the speakers should be angled in even more so that their axes cross in front of the listening area. The minimum separation between the loudspeakers is determined by their distance from the listening position. If they are placed too close together, the stereophonic stage will be narrow and restricted. Stage "width" will broaden as the speakers are moved apart, but too large a separation will give the effect of two separate sound sources with no central images and a poor blend of sound between the speakers. A good starting point is to have the separation between the speakers be the same as the distance from each speaker to the listening position. Input Sensitivity 200mV f ...
