Operating Controls - Mirage LF-100 El Manual Del Propietario

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 toggle the Phase
between 0 and 180 degrees until you've decided which provides the
fullest, most accurate bass. See diagram 4.
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 two-position switch allows fine-tuning in the form of perfect phase
matching of the subwoofer with that of your main speakers. Switched to
either 0 or 180 degrees, it compensates for the mid-bass acoustic effects of
different speaker locations and listening room effects. Also see Set-up
and Calibration.
FEATURES
Auto/On/Off
Your subwoofer is equipped with a special circuit that automatically turns
your subwoofer on as soon as it senses a program signal. At a predetermined
time after the signal ends, this circuit automatically turns the subwoofer off.
The power switch must be set in the ON position to engage this circuit.
Once the subwoofer is plugged in and the power switch has been engaged,
an LED on the control will illuminate and display a red light. This red light
indicates the subwoofer is in standby mode. When the subwoofer receives a
signal from the system, this light will turn green to indicate that it is playing.
Once the system has been turned off, the sub will return to its standby mode
after approximately 10 minutes and display the red light.
MOSFET Amplification
Metal Oxide Semiconductor Field Effect Transistors are high current, class A/B
amplifiers known for their high output capability while maintaining low
distortion levels.
