Amp Panel & Controls

  1.  RCA Stereo Inputs (Left & Right)This is the method of signal input when using a stereo amplifier system, connection can be provided by a pair of high-quality signal cables from the pre-out section of an amplifier. The crossover frequency will need to be set if using this method of connection. If using the Bronze Series speakers set the crossover dial to approximately 80Hz. This may vary depending on room and tastes.Note: cable lengths should not exceed 10 meters to avoid interference from other electrical appliances.
  2. LFE Input (RCA Type)This input is to be used when connecting the subwoofer to an AV amplifier/ receiver. When using the LFE input, the crossover frequency dial is not used. This is due to the crossover function being controlled by the AV amplifier/ processor to which it is connected.
  3. 12 Volt Trigger Input ~ Centre Pin = +12VdcFor external power control from AV amplifier/ receiver to the Bronze W10. Monitor Audio recommends using this function and a lead is supplied. A 12-volt signal is supplied by the AV amp/receiver and tells the Bronze W10 to turn on from standby mode. This allows a more accurately controlled auto on/off function and is far more energy-efficient. When using the 12v trigger, the Mode Switch (8) can be in either position, for it to function correctly.
  4. Crossover Frequency ControlThe crossover frequency control only operates when using the RCA stereo input (1) and is used to set the upper-frequency limit (low pass) of the subwoofer. The crossover control should be set in accordance with the size or bass output of the main/satellite speakers. When using the Bronze Series speakers, set this to between 50 – 100Hz (depending on additional speakers). Experimentation is advisable.
  5. Volume ControlThis control allows the level or volume to be adjusted in order to achieve a balanced overall sound. To get the balanced sound a selection of familiar music or film excerpts will need to be played. Start with the volume at a minimum and increase the level control until a balanced sound is established. If using an AV processor or AV receiver amplifier, the system can be adjusted by the test tone function within the set-up features. (Refer to the setup section in the AV processor or AV receiver amplifierBronze Series user guide.) When the subwoofer is correctly set up, you should not be able to identify its location easily in the room
  6. Bass SwitchThis switch tailors the bass response of the subwoofer to your tastes. There are three settings: Music, Movies and Impact. Movie mode provides a relatively flat response down to 35Hz. Music mode is -2dB down on Movie mode but goes lower, all the way down to 30Hz. Impact mode is +3dB up on Movie mode and comfortably goes down to 40Hz.
  7. Phase Control SwitchThe Phase Control is used to synchronize any delay between the subwoofer and main/ satellite speakers. When the subwoofer is in phase with the main/satellite speakers the sound should be full-bodied. Sit in a normal listening position whilst adjusting the phase switch. Help from another person may be required. When set correctly the location of the subwoofer should be almost undetectable. Experimentation is advised in order to achieve optimum results. However, it should be noted that in most cases the phase control switch should be set to 0 degrees.
  8. Power Mode Switch with On-Auto FacilityWith the switch in the `On’ position, the subwoofer is permanently switched on under all conditions. In the `Auto’ position the subwoofer will automatically switch on when an input signal is received. It will remain on for a period of 15 minutes without receiving a signal before switching into standby mode until a signal is received once more.Additional Notes on the Auto On FunctionWhen using the auto-on feature, the subwoofer will “lock” onto the input it was activated by. In most cases, when using either stereo or LFE input connection this will not matter. However, if using both stereo and LFE connections, you will not be able to toggle between inputs until the subwoofer has entered standby. This can be done manually by turning it off and on again, or by letting it time out (15 minutes) before changing the inputs over.
  9. Mains Power SwitchThe Mains Power Switch should be switched to the `Off’ position when the subwoofer is unused for extended periods. The switch must be in the `On’ position for the subwoofer to function.WARNING: Due to the mains switch being located on the rear panel, the apparatus must be located in the open area with no obstructions to access the mains switch.
  10. IEC Mains Power Connector/ Fuse LocationThe subwoofer is supplied with a two-pin mains input socket for connection to the mains supply. Use ONLY the appropriate IEC mains lead provided with the product. Also fitted is an external mains fuse. If this fuse blows during operation a spare fuse is provided within the fuse holder for replacement. If you wish to change the fuse, you can do this by removing the IEC mains lead and carefully levering out the original fuse from its holder below the IEC mains input socket (10a). If the fuse blows again it is advisable to seek help from an authorized service agent. DO NOT attempt to re-fit a further fuse as this could result in serious damage to the amplifier unit.
  11. Mains Voltage Selector This is factory set to your country’s mains voltage specification. Do not attempt to adjust this as this may leadto permanent damage to the product and even the risk of fire. There is a clear plastic cover over the selector to prevent accidental adjustment.

The LED on the top of the cabinet indicates whether the unit is in standby mode or operational. It will be illuminated red when in standby, and green when operational.

Positioning/Initial Set-Up

Leave the subwoofer unplugged from the mains until the installation procedure is completed.

The subwoofer should be sited in the most suitable position, preferably not directly in the corner of a room as this may cause an 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. The optimal control settings will depend entirely on system configuration, room environment, and personal tastes. However, for initial trials set the controls as follows:

Volume Control Should be set to approximately 10 o’clock.
Frequency Control Should be set to the approximate frequency depending on main speakers when using the L & R Line Level Inputs.
Bass Control Should be set to Movies when connecting to an AV receiver or Music when connecting to a stereo amplifier.
Phase Control Should be set to zero degrees.
Mode Switch Should be set to `On’.
12v Trigger (optional) Do not connect at this stage.
Input Connections from the amplifier can be made at this stage before the power is connected to the subwoofer. Refer to items 1 and 2 on page

Never connect or disconnect the RCA input/ output leads with the subwoofer switched on.


Once the input cables are connected and the controls are set in accordance with the initial set-up procedure above, the subwoofer can be connected to the mains power supply and switched on at the mains power switch.Do not play any music or movies at this stage as the auto set up of the AV amp (if using one) will need to be run. If your amp has an auto-set-up procedure, run this now. If you do not have an auto set up or are using a stereo amp connected to the left and right inputs, set the crossover in accordance with your main speakers.When the auto-setup is complete, check that the subwoofer settings on the AV amp are correct. The level should be no more/ less than +/- 3dB. If not we would suggest adjusting accordingly.Now play a variety of familiar music/film excerpts and adjust the level of the subwoofer until you are happy it integrates with the rest of the system. The volume of the amp can then be adjusted to an average listening level. Once sure everything is working correctly, double-check the subwoofer level settings.NOTE: It might be necessary to adjust the speaker/ subwoofer settings manually if they are not to your tastes or recommendations in the speaker/ subwoofer manuals.

Trouble Shooting

Should you experience any technical, or set-up problems with your subwoofer please check the Trouble Shooting guide below:My subwoofer will not turn on/with no power.

  •  Is the LED illuminated on the top of the unit? If not, check your mains lead is properly connected both at the subwoofer and at the mains outlet. Also, check the fuse of the amplifier and mains plug (where fitted).
  • Is the LED red? If so, you have power going to the unit. It could be that there is no signal, or the 12v trigger is connected and the source is not turned on (see below).
  • Have you got the 12v trigger connected? If so, the subwoofer will not power up until the source is turned on.
  • Is the unit receiving a signal (12v trigger not being used)? Is the Power Mode Switch in Auto or On position, and the signal source turned on? Try adjusting the volume level of the source.

If it still does not turn on/power-up, please contact your local dealer/ distributor or Monitor Audio immediately.No sound from the subwoofer.

  • Is the LED on the top red or green? If it is red, then the unit hasn’t actually turned on. See the above suggestions. If it is green, then your unit is powered up and turned on. Check further suggestions below.
  • Are the signal leads connected correctly? Check these. If possible, check by replacing it with a second, working set.
  • Is the volume level just very low? Try turning the volume on the source up a bit more.
  • Have you tried switching inputs? If changing from LFE to Stereo (or vice versa), you need to power down the subwoofer first. It will stay “locked” onto the input that activates it.

If it still does not output a signal, please contact your local dealer/ distributor or Monitor Audio immediately.
