Installation
Your new VA-806/907 subwoofer system provides for a number of installation options. Read all the installation information below in order to determine which installation option is best for your system.
Remember to perform all installation procedures with system power turned off.
Inputs
Your new VA-806/907 subwoofer is equipped with both speaker- level and line-level inputs. Use the LINE-IN jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level cross- over. The FROM AMPLIFIER jacks connect directly to the speaker outputs of a integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.
Note
Do not use both LINE-IN and FROM AMPLIFIER inputs simulta- neously.
Volume control
This control allows you to balance the output from the subwoofer to the main speakers in your system. To adjust the volume, start with the volume knob indicator at the "MIN" setting. With your other speakers playing, rotate the knob clockwise until you create a volume balance with your speakers. In most cases this will be somewhere between the "10 o'clock" and "2 o'clock" positions on the dial.
Warning - Turning the volume to "MAX" setting may dam- age the subwoofer with certain source material.
Low-pass crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 50 to
When using a pair of VA-806/907 subwoofers in stereo, it is preferable to place each subwoofer adjacent to the satellite of the same channel.
Keep in mind that frequency response and output level can be drastically influenced by placement depending on the acoustic properties of the listening room. Typically the VA-806/709 will sound louder when placed next to a wall or in a corner.
Caution!
The VA series subwoofers have amplifiers built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc. The power cord should be routed in such a way that it will not be walked on, pinched, or compressed in any way.
Regardless of where you install your VA-806/907 subwoofer, it must remain in an upright position (passive radiator facing down- ward). Using, shipping, or otherwise storing the VA-806/907 sub- woofer in any other position for an extended period of time may result in damage to the unit not covered by warranty.
The VA-806/907 Subwoofer is magnetically shielded to reduce magnetic emission from its cabinet to increase the number of possible locations available for placement. However, this shielding may not be adequate for all installations. Certain types of televisions are particularly sensitive to stray magnetic fields. If your television produces distorted colors after installation of your VA-806/907 subwoofer, simply increase the distance between your television and the VA-806/907 until normal color and operation is returned.
Care of your subwoofer
Do not use any harsh detergents or chemicals to clean the cabinet. Abrasives, detergents, or cleaning solutions may damage the finish on the cabinet. We recommend using a damp cloth to clean the cabinet.
During normal conditions, the VA-806/907 subwoofer may be left on continuously without any problems. The unit is equipped with a
