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.

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).
