Analyzing the monitoring environment. Teacher example.
For this example we will be evaluating the listing room, room 109Q.
The listening room has one set of B&W 802’s. The 16 thousand dollar diamond tweeter model.
They have a frequency range of 27hz all the way to 33khz. With the crossovers on the speakers set at 350hz and 4khz.
The 802’s are powered by Macintosh MC501 500watt mono amplifiers one for each side.
Those amps are then connected to the C45 stereo multi-channel preamplifier.
This is how they are placed in the room.
Notice the distance.
But the distance to the sofa in the back of the room is 12 feet. This will cause the center image to ball up and appear louder than it actually is. So ideally the sofa should be moved forward to create more of an equilateral triangle and thus a flatter more balanced image.
Since the room is square there is a build up of bass in the back corners. Bass traps can be used to help minimize this problem.
Placing one to each side of the sofa removes much of that resonance, but there are still reflections from behind the listening position.
Placing a diffuser panel behind the listening position would help minimize reflections and prevent comb filtering.PLACIN
Notice the how reflective the walls are. These reflections can be managed by using acoustical foam
Auralex is just one company to look into that could provide what we need to do that.
The florescent lights in the room are not ideal. They are on a dimmer and emit a 16khz constant tone. Removing the dimmer and adding low wattage light bulbs would be preferable.
The distance to the listening position must be shortened to an equilateral triangle
