OWNERS MANUAL

5. Filter Mode – This switch allows for the selection of either Filter On

or Filter Off. (Please see the connections section for suggestions on

which mode is appropriate for your installation).

Rear Panel

6. Power Mode – This switch

can be set to either On, Off or

Auto. If the switch is in the Off

position, the subwoofer will not

power up. If the switch is in the

On position, it will constantly

remain on. If the switch is set to

the Auto position, when a signal

is present the subwoofer will turn

on and will automatically turn off

several minutes after a signal is no

longer present.

7. Sub In – This input is an RCA type mono input.

8. High-Level Input – These are 5-way binding post type speaker con-

nectors. The High-Level inputs are designed to be used on receivers

or ampliﬁ ers that do not incorporate any RCA type subwoofer outputs.

If your receiver is equipped with an RCA type subwoofer output, these

speaker level inputs should not be utilized.

CAUTION: All power should be turned off to your system before

any connections are made. Careful attention should be taken to

ensure that all electronic components are not connected to an

AC source. Not doing so could result in potential damage to the

system.

There are two mutually exclusive methods to connect your subwoofer to

your receiver:

Method 1 – RCA – For Home Theater or LFE Applications

1. On the rear of the receiver there should be a single RCA type jack

marked “Subwoofer Out”. Connect a single RCA cable from that jack to

the RCA Sub In (#7) on the rear of the subwoofer. A standard male to

male RCA cable is needed.

2. After connecting the single low level Sub In (#7) connection, plug your

MIRAGE subwoofer into an AC outlet. Do not use the AC outlet on the

rear of your receiver.

3. Select either the Filter Mode On or Off (#5). The Filter Mode On

switch position should be used when connecting your MIRAGE subwoof-

er to a receiver without bass management or when you wish to manually

control the crossover and volume settings (such as in a music system).

The Filter Mode Off switch position should be used when connecting to

a receiver with bass management (such as in a digital surround sound

movie system). This connection defeats the crossover feature on the

MIRAGE subwoofer, allowing this control to be handled by the receiver.

Adjusting the front panel Level Control (#1) will still be required.

4. Ensure that the supplied vibration dampeners are installed in the

high-level speaker inputs, as this ensures that the inputs will not vibrate

audibly.

5. See Final System Adjustments, below.

Method 2 – Speaker Level – For Music Applications

1. The other way to connect your subwoofer to your receiver is using a

High-Level (#8) (speaker wire) connection. First remove the highlevel

vibration dampeners that are installed between the terminals and then

simply connect the speaker wires from the Front Left and Right Speaker

Outputs on your receiver to the Left and Right Inputs on the rear of the

subwoofer (#8). It is imperative that speaker polarities be maintained,

one must connect the positive and negative wires to the appropriate

positive and negative terminals. Failure to do so will result in an out of

phase connection, severely limiting the amount of bass in your system.

2. After connecting the High-Level (#8) (speaker wire) between your receiver and

subwoofer, ensure no fray wires are touching, as this could cause a short circuit and

damage your electronics. Plug your MIRAGE subwoofer into an AC outlet. Do not use

the AC outlet on the rear of your receiver.

3. See Final System Adjustments, below.

Do NOT connect both RCA (#7) and High-Level (#8) connections

simultaneously, as this will damage your MIRAGE subwoofer.

1. The Subwoofer is equipped with a master power switch which must be engaged

prior to use. After having completed the break-in process, select the correct position

for the Power Mode switch (#6), either On or Auto depending on your system. The

Auto selection will leave the unit in a self-sensing mode, such that should the unit

sense an audio signal it will turn itself on and then shut down after several minutes

without signal, while in the On position the subwoofer always remains on. Should

the system not be used for an extensive period of time, it is recommended that the

subwoofer be unplugged from the AC outlet.

2. Adjust the Level Control (#1) on the front panel of your MIRAGE subwoofer so that

the volume of your subwoofer matches the overall system volume. This ensures

a smooth transition between the low and high frequencies of your system.

3. Adjust the Frequency Setting (#3) on your MIRAGE Speakers subwoofer so

that the frequency range of the subwoofer blends well with that of the front speak-

ers (For use with all settings, except when in Filter Mode Off). Setting the crossover

too low will create a gap between the frequency response of the front speakers and

that of the subwoofer, while setting the crossover frequency too high will create a

doubling of certain frequencies, making the music sound boomy. When using small

satellite speakers, the appropriate crossover frequency should be from 95Hz to

120Hz, for the bookshelf speakers 65Hz to 95Hz and for the large crossover

ﬂ oorstanding speakers 40Hz to 65Hz.

4. Adjust the Phase control (#4) so that the subwoofer integrates fully with the rest of

your audio system. This control is adjustable to either 0 degrees or 180 degrees, and

ensuring that the subwoofer operates in phase with the rest of the system is critical,

as an out of phase subwoofer will either sound like it is lacking in bass performance or

that its timing is off. This setting will be determined by your listening position, the char-

acteristics of your listening room and its interaction with your MIRAGE subwoofer. An

out of phase speaker means that the speaker cone is moving inwards when it should

be moving outwards, like the other speakers in your system, causing cancellations of

certain frequencies. By adjusting the phase control, one can ensure that all speakers

move in the proper direction, at the same time.

5. Steps 2, 3 and 4 might require repeating in order to ﬁ ne tune your system. Ensuring

the proper blending between the speakers and the subwoofer is critical to the perfor-

mance of your system, as a whole.

Outside of North America, the warranty may be changed to comply with local

regulations. Ask your local MIRAGE dealer for details of the LIMITED
