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. 11.IEC Mains Power Connector/ Fuse Location The AW-12 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 a 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 (11a). If the fuse blows again it is advisable to seek help from an authorised service agent. DO NOT attempt to re-fit a further fuse as this could result in serious damage to the amplifier unit. 12.Volume Control This control allows the level or volume to be adjusted in order to achieve a balanced overall sound. To use this facility you will need to play a selection of familiar music or film excerpts. Start with the volume at minimum and increase the level control until a balanced sound is established. If using an AV processor or AV receiver amplifier, the system can adjusted by the test tone function within the set-up features. (Refer to the set up section in the AV processor or AV receiver amplifier user guide.) When the AW-12 is correctly set-up, you should not be able to identify its location easily in the room. 13.EQ 1 setting The EQ 1 setting should be set as a default option. This will provide the best overall transient response and power output. This setting will provide a maximally flat response suitable for music or music video. Note: Frequency roll off starts at 27Hz. 14.EQ 2 setting The EQ 2 setting should be used when an emphasis in the low frequency is required. An additional boost of 4dB will be provided at 21Hz to give impact essential for action movies. You can toggle between the EQ1 and EQ2 to test which one is best suited to your environment. This is done by pressing the buttons located on the control panel. The blue LED’s of the EQ buttons will remain on permanently. This indicates that the unit is in stand by mode when not in use. monitoraudio.co.uk Positioning/Initial Set Up Leave the AW-12 unplugged from the mains until the installation procedure is completed. The AW-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. The optimal control settings will depend entirely on your system configuration. For initial trials set the controls as follows: Volume Control Should be set to minimum Frequency Control Should be set to the minimum position (40Hz) Phase Control Should be set to zero degrees Power Mode Switch Should be set to ‘Auto’ (if not using 12v trigger) 12v Trigger Should be connected using the supplied (or similar) lead to the output from your AV amplifier. EQ Setting This will be set as EQ1 by default when powered up Low Pass Filter Switch Should be set to the ‘Out’ position Input connections can be made at this stage before the power is connected to the AW-12. Never connect or disconnect the RCA input/ output lead connection with the AW-12 switched on. Set Up Once the input cables are connected and the controls are set in accordance with the initial set-up procedure above, the AW-12 can be connected to the mains power supply and switched on at the mains power switch. Do not play any music at this stage. With the 12v trigger connected or Power Mode Switch in the ‘Auto’ position, the unit should remain in standby (Power LED on the amp panel should be red, and the EQ1 button illuminated blue) until the AV amp is turned on or a signal is received (when not using the 12v trigger). Play a variety of music/ film excerpts that you are familiar with starting at a very low volume level, increasing to an average listening level once you are sure everything is working correctly. Please now follow the bulleted instructions below: • For use with an AV amp/receiver (product with Subwoofer output) please select the low pass filter switch to the ‘Out’ position. Otherwise select low pass filter switch to the ‘On’ position. This engages the crossover frequency control on the subwoofer (please refer to page 6). • If u sing the crossover frequency control please adjust in accordance with the table on page 6. Further fine- tuning may be required. • Adjust the Volume Control to desired level for initial trials, ref. page 7 • The Phase Control can now be set, please refer to page 6 for further information. It is important to try a variety of music and film excerpts with which you are familiar in order to obtain the optimum overall settings. mo...
