Initial Set Up

Leave the Silver W-12 unplugged from the mains until all signal cables are connected.
The W-12 should now be sited in the most suitable position, preferably not directly in the corner of a room
as this may cause excessive bass boom. Once a desirable position is achieved it is important to check if
the cables are long enough to reach comfortably without being under tension. Cables should be less than
10 metres to avoid interference.
Never connect or disconnect the RCA input/ output leads with the Silver W-12 switched
on.
For initial setting up, put the Power Mode Switch in the 'On' position and leave the 12v trigger cable
disconnected.
Once the input (and output if necessary) cables are connected and the power mode switch is in the On
position, the W-12 can be connected to the mains power supply and switched on at the mains power
switch.

Power Cycle

When the W-12 powers up for the first time or when it has been turned off for a long period, the EQ button
will flash red 3 times while powering up and then go in to standby mode (if power mode switch is in the
auto position).
When it senses a signal or is activated by the 12v trigger, the LED will illuminate white while booting and
then the colour of the previously sleceted (or default) EQ profile.
If the power mode switch is in the On position it will be white while booting up and then to the colour of
the previously selected (or default) EQ profile.
To continue with the set up procedure, put the power mode switch in the 'On' position so that the APC can
be initiated.

Automatic Position Correction

Automatic Position Correction (APC) will optimise the acoustic output of the subwoofer to match the ideal
system performance by removing the dominant room modes from the listening position. The APC will take
measurements from 3 different seating locations within the room to achieve the most accurate correction.
NOTE: Please run the APC before running the automatic room set up of your AV amplifier.
To perform APC, follow the steps listed below:
1. Pressing the Calibration Button (item 2, page 5) while in normal operation will enter calibration mode.
A flashing blue LED in the calibration button indicates that the subwoofer is ready to perform an APC
measurement.
2. Place the microphone in the normal listening position, then press the EQ button to activate a room
measurement. This will flash cyan and a series of tones will be heard.
If it doesn't get a good enough reading, the EQ button LED will blink red and the sub will run the test
tones again until it gets an accurate enough measurement. The LED will then blink green, then purple
(processing the equalisation) and go off. The Calibration button will be flashing blue indicating that it
needs to run a second and third set of tones.
3. Repeat step 2 in another 2 listening positions to provide more room information for the subwoofer.
Good locations for the 2nd and 3rd measurements would be 1m to the immediate left and right of the
initial listening position.

The subwoofer will then calculate the error between the current listening position and the ideal frequency
response of the system, then calculate and apply digital filters to optimise the listening experience for the
room.
When it has completed the APC the Calibration Button LED will go off, and the EQ Button LED will go the
colour of the previously selected EQ profile.
If you do not wish to run a second and third APC frequency sweep, you can cancel the test by pressing the
Calibration Button again.

Connected to an AV Receiver

The majority of AV amplifiers have automatic setup systems. If your amp has an auto set up procedure, run
this now with the volume set to around 10 - 12 o'clock, and the power mode switch in the On position.
When the auto set up is complete check the settings on the AV amp for the sub woofer to ensure they
are correct. The crossover frequency should be roughly the same as in the table on page 3 and the level
should be no more/ less than +/- 3dB. If not we would suggest adjusting accordingly.
Now play a variety of music/ film excerpts that you are familiar with gradually increasing the volume to an
average listening level once you are sure everything is working correctly.

Connected to a Stereo Amplifier

Stereo L & R input may be required if using a 2-channel stereo amplifier, or an amplifier with no LFE output.
Connect 2 x interconnect cables (left and right) from an amplifier to connections marked Inputs L & R.
With the pre/ integrated amplifier set to a low level, set the subwoofer up using the suggested guide below
before playing any music/ test tones.
• Set the volume to around 10 o'clock (Page 5)
• Frequency should be set in accordance to your main speakers (refer to the table on Page 3)
• Phase to 0 (Page 4)
Now play some familiar music and gradually adjust the volume and/ or the frequency until happy with the
integration and balance of the sub woofer with the rest of the system.
