Apex Digital AW-12 owner manual Positioning/Initial Set Up

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 using 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.
