SPEAKER PLACEMENT:
The A-20 Monitor System is intended to provide consistent performance over a wide range of placement situations. This is accomplished through the use of electrical controls, wide dispersion drivers, advanced enclosure design and carefully chosen crossover characteristics. Nevertheless, it is always worth investing time and effort experimenting with optimum loudspeaker placement. In all cases, A-20 Monitors should be set up symmetrically equidistant from the listening position; the left speaker and right speaker should be at the same relative positions with respect to the primary listening area. This is important in order the hear a proper stereo sound stage. The speaker baffles angle in towards the listening position with the loudspeaker backs parallel to one another. A good starting point can be found in Figure 8 below. Ideally, the tweeter height should be on axis with your ears, or slightly above. Also, remember that nearby reflective surfaces can alter impulse response, blur imaging and change tonality.

SYSTEM OPERATION:
The A-20 is capable of very high output levels, especially when listening in the near-field. Protect your ears and use common sense. Still, every speaker system has its limits. Harsh breakup at extremely high volume, or heat emanating from the drivers is an indication that the system has exceeded its output limits and you should lower the playback level. Watch for excessive lighting of the front panel overload indicator on the Control Amplifier. Speaker damage most often occurs from sustained high volume levels, not from transient sounds or brief musical peaks.
A-20 MONITOR SYSTEM CARE:
Except for the occasional flattering comment, your A-20 System needs no regular maintenance. Never attempt to clean the A- 20 monitor driver units except for very light feather dusting. The A-20 monitor cabinets and the A-20 Control Amplifier front panel can be cleaned using a damp, soft cotton cloth first sprayed with a mild, non-abrasive glass cleaner. Never spray the speaker or amplifier directly! Avoid silicone and oil based cleaners or treatments.
