Safety Precautions

At AV123, we don’t want to see any of our 

customers experience the inconvenience 

or unfortunate mishap of a precaution that 

was ignored. Please review the following 

precautions so you may enjoy your Strata 

Mini speakers without unnecessary damage or 

misuse.

1) If you suspect you have a component failure in 

your speakers at any time, please call AV123 for help. Our experts can assist you in diagnosis and, if 

necessary, provide you with field repair parts where applicable. Our goal is your complete satisfaction.

2) Do not lift these speakers if you feel strain or they are just plain too heavy for you. The weight of each 

Strata Mini speaker is listed in the Technical Specifications section of this manual for your reference.

3) When lifting these speakers, do so with caution. If you need to use a cart or hand truck to move them 

around to their final destination, please do so with care and caution. Odd shaped boxes may require a 2 

person lift even if the weight of the box does not seem prohibitive. 

4) Do not install these speakers near water (or expose them to water) or any other liquids. If you have 

a place in the basement that floods or a leaky roof in certain spots, do not install your Strata Mini 

speakers (or any other home entertainment equipment) in that location. Use good judgement, but if 

you are not sure if your chosen location is acceptable, chances are you should call us. It never hurts to 

ask. 

5) Do not poke, prod, or “heavily pet” these speakers. Do not set drinks on them (or it’s just about 

guaranteed the drinks will leave a ring and spill too). Do not use the speakers as tables or chairs. 

Whenever possible, ask the kids and pets to play elsewhere than on (or directly in front of) the 

speakers. All of these suggestions come from many years of experience by our AV123 experts so you 

can trust the origin. 

6) Do not install these speakers near a heat source such as a floor heater, space heater, fireplace, stove, 

heat register, active volcano, or any other device (including amplifiers) that may radiate heat. 

7) Plug the electrical power cord for the integrated amplifier into a line conditioner or connect to an 

unswitched 110VAC wall outlet directly. Do not connect the 8” woofer amplifier’s power cord into a 

“power strip”. This ensures the best performance and avoids power delivery related problems.

8) Do not plug the Strata Mini speaker binding posts into the wall, EVER. Some people think it’s a great 

way to test the excursion limits of a low frequency driver but in truth it’s very dangerous. Just hook 

them to the amplifier outputs as recommended in this manual please. 

9) These speakers in a home entertainment environment can easily produce high sound pressure levels 

that can impair hearing if you (or other listeners) undergo extended exposure. Use caution when 

listening at high volumes and, by all means, please discontinue use if your ears are ringing. If you must 

play these speakers at extremely high volumes, we recommend the use of OSHA approved hearing 

protection.

10) Please read and follow the instructions in this manual. Keep this manual for future reference.

IMPORTANT!

PLEASE READ THESE 

INSTRUCTIONS 

CAREFULLY
