C L E A N I N G Cleaning Wooden baffles The final wood finish coat is wax, which will be removed by most cleaners. Wipe only with a soft, damp cloth. Painted and metal surfaces These surfaces can withstand strong cleaners as well as alcohol, but do not spray anything directly onto the speakers. -
Page 12: Quick Start
S T A R T Quick Start t mid and high frequencies, the zA1.1’s directivity keeps the stereo image from being affected much by room placement in all but the most reflective rooms. As with any non-dipole speakers, though, the bass is practically omnidirectional, so nearby walls will reinforce it. -
Page 13: Tips
Q U I C K S T A R T • Positioned a different distance from the side walls as from the front wall, to prevent overlap of the reinforcement spectra. For smoothest bass, the side wall distances should be asymmetrical, with the pair shifted a foot or so to one side, and for best imaging, they should be symmetrical. - Page 14 Q U I C K S T A R T o Add absorption or diffusion at the side wall first reflection points. o Make the side to side position symmetrical • Upper treble response can be rolled off to taste by reducing toe-in. •...

Page 15: Connecting And Powering
C O N N E C T I N G A N D P O W E R I N G Connecting and Powering Binding Posts The standard binding posts accept spades or bare wire, but not banana plugs, although they can be clamped into the posts in a pinch, so to speak. We have nothing against banana plugs, but came to appreciate the design of the Cardas Patented post assembly, with its handy, single knob clamping mechanism, solid copper posts, and rhodium plating. -
Page 16: Powering
C O N N E C T I N G A N D P O W E R I N G There is consequently no benefit to using a special power cord. The bias supply will work correctly with any mains voltage, and if the speakers are moved internationally, suitable power cords for any wall socket arrangement can be obtained worldwide and used without concern for converting/adapting the voltage. - Page 17 A I R L A Y E R airLayer Option As of this writing, this option is not yet available on the zA1.1, but will be eventually. It is available on the zA2.1. The zA1.1 speakers are very directive in the vertical, and rather directive in the horizontal.

Page 18: Setup Details
Setup Details Height The zA1.1 speakers are very directive in the vertical. There is thus about a 22 cm [9”] range of ear height that will experience full spectrum sound. It is thus important to ensure that your speakers are placed so that the center of the rectangular electrostatic element within an inch or two of your ear height when you are seated. -

S E T U P D E T A I L S already relatively well damped, then diffusion is preferable, which will control the direct reflections without decreasing “air”. Room Compensation To start, in a moderately lively, fairly large room, you will probably get the best sound when the speakers are toed in so that they face each of your shoulders or toward a position a couple of feet behind you. - Page 20 S E T U P D E T A I L S You can make some headway against these effects with no additional hardware by decreasing the setup symmetry. This is done by placing each speaker a different distance from each side wall or rotating your entire listening triangle 10 or 15 degrees relative to the walls or both.
