Dolby Digital Systems: Xover Bypass
This method bypasses all subwoofer controls, other than phase, in favor of the bass management controls integrated into your receiver or processor.
The rear panel is equipped with a low level input marked Xover Bypass.This method uses an RCA cable to connect the “Subwoofer Output” jack from your receiver or processor to the Xover Input on the rear panel of the subwoofer. See diagrams 2, 3.
Recommended connection for Dolby Pro Logic systems: Input
The rear panel is equipped with a low level terminal marked Input. Connect a single RCA to RCA interconnect cable to what is commonly referred to as the “Subwoofer Output” jack from your receiver or processor to the Input on the rear panel of the subwoofer. This connection allows full use of all subwoofer controls. See diagrams 2, 3.
Recommended connection for Stereo applications: High Level Inputs and High Level Outputs
Located on the rear of your MIRAGE subwoofer are 4 sets of binding posts. The pair marked Inputs should be connected to the left and right speaker terminals of your amplifier or receiver. Each pair is color-coded black/red. These terminals will accept up to 12-gauge quality speaker wire. Remember: Always connect red-to-red and black-to-black when making connections between amplifier/receiver to subwoofer. If you inadvertently reverse one of the connections (i.e., red to black), you will notice a lack of bass from your subwoofer.
The second pair of high-level terminals are marked High Level Outputs and can be used to transfer a signal to your speakers. Using speaker wire, connect the left and right outputs to the rightful speaker inputs. Each pair is color- coded black/red.These terminals will accept up to 12-gauge quality speaker wire. Remember: Always connect red-to-red and black-to-black when making connections between amplifier/receiver to subwoofer. If you inadvertently reverse one of the connections (i.e., red to black), you will notice a lack of bass from your subwoofer. See diagram 3.
Set Up Calibration for High Level and Subwoofer Input Connections
*As previously mentioned, the Xover Bypass input renders the subwoofer’s controls, other than phase, inoperative in favor of the bass management controls integrated into you receiver or processor. Simply turn the subwoofer on and follow the guidelines of your processor’s manual.
For best results when setting up your system, assume your normal listening position and, if possible, have another person perform the following adjustments.
1.Complete your connection method and turn the subwoofer on.
2.Set the subwoofer Level control to its lowest position, completely counter clockwise. Set the subwoofer Frequency control to its lowest position, completely counter clockwise. Play a familiar piece of music or video soundtrack that has substantial bass content.
3.Gradually turn the subwoofer Level control clockwise until you achieve a neutral volume balance between the subwoofer’s deep bass output and your main speakers. See diagram 4.
4.Slowly turn the subwoofer Frequency control clockwise to reach the best midbass with your main speakers. This will be the point at which bass retains solid impact and fullness. If the bass is too boomy or ill defined, you have gone too far and should turn the control counterclockwise to the best balance point. If the sound is too thin, then turn the control clockwise to the best balance point.
See diagram 4.
5.While in your listening position, have someone slowly adjust the Phase between -180 and 180 degrees until you’ve decided what provides the fullest, most accurate bass.
6.You may have to readjust the Level Control due to the effect of the Phase Control.
The Subwoofer Level Control is designed to control the balance between your subwoofer and main speakers and should not be used as a substitute for the bass and loudness controls on your amplifier or receiver. Adjust the subwoofer’s levels for smoothest low frequency performance. If more bass is desired, then advance the bass and/or loudness controls on your main amplifier or receiver.
OPERATING CONTROLS
Power Switch
The power switch must be set into the ON position before the subwoofer becomes operational. Once it is turned on, the Auto/On/Off circuitry is engaged. Setting the switch to Off stops all power and functionality of the subwoofer.The dot symbol on the power switch represents the “ON” position, the unlabeled side represents the “OFF” position.
Level Control
This rotary control adjusts the output level of your MIRAGE subwoofer and should be used to balance the level of the subwoofer with that of your main speakers. Also see Set-up and Calibration.
Frequency Control
This rotary control adjusts the high frequency roll-off of the subwoofer. Continuously variable from 40Hz to 120Hz, it is used to precisely match the subwoofer bass reproduction with that of your main speakers. Also see Set-up and Calibration.
Phase Control
This rotary control allows fine-tuning in the form of perfect phase matching of the subwoofer with that of your main speakers. Variable from -180 to 180 degrees, it compensates for the mid-bass acoustic effects of different speaker locations and listening room effects. Also see Set-up and Calibration.
Video Mode
This switch allows a quick and simple way of boosting the deep bass characteristics of your subwoofer by adding approximately 3 db in the 40Hz range.
