English The "Sweet Spot" 60˚ For both stereo and surround mixing your position in relation to the main front speakers - the "sweet spot" as it's often called - should be one apex of an equilateral triangle. In other words your distance from either speaker should be the same as the distance between the two speakers. The speakers should also be "toed in" to the corresponding 60° angle so that the drivers are aimed directly at the listening position. The height of the speakers should be such that the tweeters are roughly aligned with your ears (this is because high frequencies are the most directional). Fine-tuning for Stereo ● The speaker LEVEL controls should be set to the same level. A setting of about 12 o'clock corresponds to a nominal input level of about +4 dB. ● Since no subwoofer is being used in this setup, set the LOW CUT switch to "FLAT". ● When set to "-2 dB" the EQ MID switch attenuates the midrange frequencies slightly to produce a somewhat "softer" sound that may be better for listening or long monitoring sessions. For accurate monitoring, however, set the MID switch to "0". ● Set the ROOM CONTROL switch according to the distance your speakers are placed from the nearest wall (refer to "Proximity to Walls and Corners", above). ● For accurate monitoring set the HIGH TRIM switch to "0". This switch can be set to "-2 dB" to attenuate the highs slightly if you find the sound too bright. 8 HS80M/HS50M/HS10W Owner's Manual
