6.4 Mounting
Please respect the instructions given in the “Technical Data Sheet” of each product.
Remember that any loudspeaker positioned above floor level represents a fall hazard. Make sure
your loudspeakers are always securely positioned or mounted in a stable position and can’t fall. In
particular make sure no child can make them fall.
6.5 Stereo Operation
Position the loudspeakers so that the position between the listener, the left and right loudspeakers
determine an equilateral triangle. The acoustic axis (see the Technical datasheet of your PSI audio
monitor) should be at ear height or slightly higher. This is valid for any music listening mode (stereo,
multichanel, etc..).
6.6 Stereo + Sub Operation
For music listening, the role of the subwoofer is to extend the low frequency response and the
maximum sound pressure level in a linear fashion. The placement of a subwoofer, especially in a
small control room, can be critical. It is recommended that the user takes some time to find the
optimum position.
Calibration procedure
The monitor Roll Off is positioned at –10dB.
The subwoofer is placed on the floor.
The distance from the subwoofer to the listener is equal to the distance from the monitor to the
listener (± 0.5m).
Because of its complementary response, the largest part of very low frequencies are spread by the
subwoofer.
• Subwoofer level calibration:
The first monitor is temporarily positioned in free standing, and the signal is directly applied.
Level : Cal
Roll Off : Cal
The second monitor and the subwoofer are placed at their normal positions, and the signal is applied
through the subwoofer.
Level : Cal
Roll Off : -10dB
Signal : between 70 to 150 Hz (i.e. cello low note)
