3. Heed the warnings – All warn ngs about these speakers should be followed.
4. Follow the instructions – All operat ng and use nstruct ons about these
speakers should be followed.
5. Condensation – When mov ng the speakers from a cold to warm locat on,
such as dur ng del very on a cold w nter day, mo sture may condense on
components w th n. If th s should occur, the speakers m ght not operate
properly. Consequently, after br ng ng the speakers n from the cold, we
adv se leav ng them dle for a day before connecting or powering them.
6. Water and moisture – The speakers should not be used near water – for
example, they should not be placed near a bathtub, pool, s nk, lawn spr nkler,
etc., and generally should not be placed outdoors.
7. Heat and flames – The speakers should be located well away from strong
sources of heat or flames, such as f replaces, propane heaters, stoves, etc..
. Particulates – Smoke from tobacco or cook ng, aerosol or splattered grease
from cook ng, and a r pollut on over a long per od of t me can have a
deleter ous effect on any speakers, nclud ng these. In part cular, avo d
spray ng anyth ng anywhere near the speakers.
9. Power cords – As w th any power cords, they should be routed so that they
are not l kely to be walked on or p nched by heavy objects. It s also mportant
to prevent access from an mals or ch ldren that may chew or otherw se
damage the power cords.
10. Liquids – Care should be taken not to sp ll l qu ds onto the speakers.

cleaner, l ghter flu d, alcohol, kerosene, or naptha. Avo d gett ng any of these
substances on the wood or gr lls. Apply any of these to a soft cloth. W pe gently,
because w p ng hard can pol sh away the matte f n sh and leave a sh ny area.
Wood: The wooden surfaces should be w ped w th noth ng more than a soft
cloth dampened w th pla n water. Do not use cleaners, pol shes, cond t oners,

13. YOUR EARS – D stort on and compress on are what make ord nary
speakers seem loud when the volume goes up, but electrostat c speakers do
not do th s.
Because your zA2.1’s are capable of produc ng h gh sound pressure levels
(SPL) w thout d stort on or compress on, t s easy to exceed safe loudness
w thout not c ng. As a general rule, f you can feel the bass n your belly, or f
you have to shout to be heard by a person s tt ng next to you, t m ght be too
loud.
A pa r of zA2.1 speakers can produce a peak SPL of over 108 dB, even n a
fa rly large room, 114 dB n a small room, and w th some k nds of mus c, a
steady level over 100 dB s poss ble. This can damage your ears
permanently, and fairly quickly.
If you hear r ng ng n your ears soon after or w th n a day or so of l sten ng to
loud mus c, you have damaged your ears, perhaps sl ghtly, but permanently. It
s also poss ble to damage your ears even w thout hear ng r ng ng.
It s mportant to know --
No one notices the usual bits of hearing loss right away after each
overexposure. It adds up over time. If you don't avo d exposure to loud
sound, then at a relat vely young age, mus c w ll sound dull, or certa n notes
w ll be m ss ng, or you w ll hear constant no se n your ears, and you w ll have
trouble understand ng what people are say ng, f rst n no sy places l ke
restaurants, and then everywhere. If you th nk you may already have hear ng
loss, t’s never too late to stop mak ng t worse.
15 minutes s the NIOSH and CDC 2002 recommended maximum
exposure time to a steady SPL of 100 dB. The t me l m t s 4 hours at 85
dB. Th s 4 hour t me l m t s cut n half for each add t onal 3 dB n loudness: 2
hours at 88 dB, 1 hour at 91 dB, and so on.
SO PLEASE BE CAREFUL and you will not hurt your ears and thus
your future enjoyment of music.
You can measure loudness w th a s mple sound level meter. If you w sh to
check your exposure, JansZen can supply a good qual ty sound level meter
such as we use ourselves at modest cost. Rad o Shack also offers one. There
are also apps for smart phones that work as sound level meters and spectrum
analyzers, although they w ll probably m ss the h gh frequency extremes due
to m crophone qual ty. Follow the nstruct ons for the dev ce or app to make
sure your read ngs are val d.

Unpacking
o not allow the delivery person to leave until you are satisfied that there
has been no shipping damage.
If there s damage, please refuse the sh pment, and t w ll automat cally come
back to us for repa r/replacement. The s tuat on w ll be harder to handle f you not ce
damage after the del very person has left.
Carton contents
Each of the two cartons should conta n one speaker and one power cord, and one of
these should also conta n one bag of sh m washers. If you have ordered carpet sp kes
for self- nstallat on, one carton w ll have both packages of sp kes.
Unpacking
The follow ng steps w ll get your new speakers out of the cartons and onto your floor
w thout m shap:
1) Move the carton onto a carpeted area, or lay a blanket, bath towel, or other
soft mater al down onto the floor to use as an unpack ng surface.
2) Set the carton on ts long s de w th the flaps up, wh ch matches the “th s
s de up” mark ngs on the s des of the carton, and sl ce through the tape to
free the flaps. We’ll call th s s de the top.
3) Remove the power cord, the bag of sh m washers, and f appl cable, the
boxes of carpet sp kes.
4) Bend the flaps back as far as poss ble. If you are work ng alone, the next
steps w ll be eas er f you tape the flaps down aga nst the s des of the
carton.
5) Roll the carton completely over so that the top has now become the
bottom.
6) L ft the carton away and set t as de.
7) L ft the blue foam nsert away from the speaker.
8) Grasp the top end of the speaker, press ng the rema n ng blue foam nsert
aga nst the speaker so that the two do not separate.

9) Gently t lt the speaker up unt l t s vert cal, then further unt l the feet to
the s de w th no nsert touch the floor.
10) Wh le cont nu ng to support the speaker, remove the rema n ng blue foam
nsert, and let the speaker down onto all ts feet.
11) Cl p the t e that holds the bag shut, and sl p the bag part ally down.
12) Place the speaker onto ts top by t pp ng onto ts face f rst, then up onto
ts top, remove the bag, and f nally turn t back onto ts feet.
13) Remove the protect ve f lm from the enclosure.
14) We adv se that you reta n all pack ng mater als n case you want to sell or
return the speakers. The cartons can be folded flat, and the nserts can be
nterleaved to occupy less space.
Feet
If the speakers were f tted w th rubber feet, and you w sh to sw tch over to
carpet sp kes:
1) Lay the speaker onto ts face on a carpeted or other soft surface.
2) Us ng a #3 Ph l ps screwdr ver, remove the screws hold ng the feet n
place.
3) Locate the studs n the package of sp kes.
4) Screw the studs nto the nserts n the speaker base. The studs have a slot
at one end to fac l tate th s.
5) Screw the sp kes onto the studs.
6) If the sp kes have been ordered for use on carpet ng, as we would adv se
to make f rm contact w th the floor, ensure that the adjustable t ps are
screwed n t ghtly.
7) If the sp kes are for use on hard floors, metal pads are ncluded to avo d
damage to the floor, and the adjustable t ps can be used to accommodate
uneven surfaces.
Grills
The speakers are des gned to offer opt mal sound reproduct on w th the gr lls n
place, and they also help protect the electrostat c elements, both from mechan cal
damage and from collect ng part culates from the a r.
The gr lls are permanently nstalled. Any attempt to remove them w ll cause
rreparable damage.

Moving
he speakers we gh about 28 kg [62 pounds], so they can be hard to move
for someone work ng alone. If you are unpack ng these alone, here are a
few suggest ons.
Large movements
The eas est way to p ck one up s:
1) Ensure that your cloth ng presents no exposed hardware, such as a belt
buckle, snaps, r vets, buttons, etc., that could come nto contact w th the
speaker and scratch the pa nt or wood.
2) Stand ng to one s de, t lt the speaker forward, allow ng t to rest on one
hand.
3) Grasp the far upper foot on the base w th your other hand.
4) L ft using your knees. Do not stra n your back by l ft ng w th your back.
5) To get through doorways, rotate the speaker onto your h p or up onto the
hand that s grasp ng the foot.
Small movements
When f tted w th rubber feet, the eas est way to move a speaker by small amounts
s to t lt t onto two feet and walk t along by rock ng t back and forth onto one
foot at a t me wh le rotat ng t each t me t’s on one foot.
When f tted w th carpet sp kes, damage to the carpet s l kely when attempt ng to
walk the speakers. In th s case, you would do well to place a pa r of wooden or
plast c slats under pa rs of feet and sl de the speaker along on these l ke a sled.
