INTRODUCTION Congratulations on your purchase of the APS AEON active monitor. AEON is designed to provide many years of excellent and trouble free audio reproduction. It is most important, however, that you take a few minutes to read this manual. It contains essential information to make you get the best from your new monitors. General Information AEON is a professional studio monitor for near-medium field, designed for accurate sound realization.
REAR PANEL Correct setup is essential to achieve optimal performance from your monitors. Please follow the instructions on the following pages.
1. AC input and fuse 2. Power on/off switch 3. Input Sensitivity Switch 4. Tweeter Loudspeaker Level Switch 5. Bass Controller Level Switch 6. Bass Controller Switch 7. Ground Lift Switch 8. XLR symmetrical (balanced) output 9. XLR symmetrical (balanced) input Switches On the rear of the monitor you will find switches for setting up the monitor for optimum performance in different acoustic and electric environments. Each switch is explained in the following. 3.
The tweeter is protected by an electronic Tweeter Protection System limiting overdrive of its dedicated Power Amplifier. The Tweeter Power Amplifier is equipped with thermal, short circuit and over-current protections. There are also interference eliminators operating during switch-on and switch-off. The woofer is similarly protected by its own Woofer Protection System. The woofer section is also equipped with its own thermal sensor and is protected by a specially designed Power Amplifier Controller.
A B A=B Step 2 Install the Stick-On Feet in suitable places of the monitor base near the corners to ensure its stability. Step 3 Put monitors in a vertical position – standing up, (although horizontal position - lying down - is also permissible), so that the center (Tweeter Loudspeaker axis) will be located at the ear-level of the listener. Step 4 Turn each monitor so that the Tweeter Loudspeaker will be turned in the direction of the listener.
Remark 4 It is necessary to match the location of the monitor, the listener’s head and reflecting surfaces (e.g. mixer console surface) to avoid a situation in which the reflected sound directly reaches the listener’s ears. Illustrating: it is best to choose such a location for the monitors so that they will not be visible in a mirror put on the mixer console halfway between the listener’s face and each monitor.
Connecting and Starting Step 1 Adjust all regulators in 0 dBu and 0 dB positions before connecting. Step 2 Adjust output level of signal source in the minimum position. Remark 1 If a value of source output level is not known, then the safest method is to adjust the Input Sensitivity Switch in 30 dBu position. Step 3 Bass Controller Switch should be adjusted in the switch-on position, with GROUND LIFT Switch in the switch-off position. Step 4 Adjust the Power Switch adjustment in the switch-off position.
Remark 6 Power cables of the monitor and a signal source connect best to the same power sockets unit. Step 7 Adjust suitable source (e.g. mixer console) output level slowly. Remark 7 Change the level by means of Input Sensitivity Switch especially if it was adjusted in 30 dBu position.
