Figure 2. Subwoofer positioning
The figure to the left shows some example subwoofer positions within a room. Unless mentioned otherwise, the vents of the subwoofer should face towards the nearest wall.
1Recommended position.
2& 3 Recommended only when using two subwoofers.
4This arrangement may cause a loss in low frequencies if the distance from the listening position to the front wall is between 1 and 3m.
5The 'Soffit' or flush mount is also recommended. Here the vents must radiate into the room.
Positioning in the Room |
| Safety Considerations |
| Overload Indicators |
The placement of the subwoofer in the room will affect the overall frequency response of the system as, with low frequencies, the effects of the room are more apparent.
The subwoofer radiation ports should be placed within 1m of a wall. The amplifier panel should not be positioned less than 10 cm from a surface, as this may cause heat dissipation problems from the amplifier back plate. The placement will affect the phase difference between the main monitors and the subwoofer, and also the bass
The 1094A/92A has been designed in accordance with international safety standards. However, to ensure safe operation and maintain the instrument under safe operating conditions the following warnings and cautions should be observed.
-Servicing and adjustment should only be performed by qualified service personnel.
-Opening the amplifier's rear panel is strictly prohibited except by such persons who are aware of the hazards involved.
-It is forbidden to use this product with an unearthed mains cable, which may lead to personal injury.
Warning!
The 1094A contains a red 'Clip' LED. This indicator is located on the rear panel of the subwoofer.
The clip LED will light if the amplifier is overloaded. If this occurs frequently, reduce the input level to the subwoofer until the clip LED stops blinking.
Choose a central and symmetrical position for the subwoofer as this will give an even phase match between all monitor channels. Positioning the subwoofer close to a corner should be avoided as it will boost the bass level at lower frequencies and may cause asymmetrical spatial imaging.
See the section titled 'Subwoofer Positioning' for examples of recommended positions within a room.
This equipment is capable of delivering sound pressure levels in excess of 85dB, which may cause permanent hearing damage.
