Connections

For the best sound quality and signal transfer, AV123 recommends a minimum of 16 

gauge high quality, multi stranded, oxygen free copper speaker cables. Speaker wiring 

connections are accomplished through the 5-way binding posts.

Speaker Binding Post Connections

Connect the amplifier’s LEFT channel outputs to the positive and 

negative input terminals of the LEFT Strata Mini speaker, being sure 

to observe correct polarity. Connect the amplifier’s RIGHT channel 

outputs to the positive and negative input terminals of the RIGHT 

speaker, again being sure to observe correct polarity. Refer to your 

amplifier’s connection manual to ensure the component is suitable 

for driving 8 Ohm per channel loads.

Powered 8” Woofer Connections

Although there is technically no connection necessary to the 

driver itself (we’ve already done that part) you do have to choose 

connections for the audio input to the Strata Mini’s 8” Woofer 

amplifier. There are several ways in which to accomplish this:

Speaker Level Inputs

After careful consideration, we at AV123 have determined that the 

very best sounding method

 for connecting the active 8” Woofer 

with the other speakers in the Strata Mini loudspeaker via high level 

inputs is to do the following:

1) Connect the speaker binding posts 

directly to the outputs of 

your main amplifier

. The left channel from the amplifier/receiver 

will connect to the LEFT + and - binding post, then the right channel 

from the amplifier/receiver will connect to the RIGHT + and - binding 

post. 
2) Next, connect a second pair of speaker wires from each binding 

post to the respective RIGHT 

high level input

 on the built in 

amplifier. Using the right channel only is AV123’s recommended 

method because leaving the left high level channel open is used 

for a noise cancellation trick if the 8” Woofer amplifier experiences 

powerline “hum”. See photo at right for an example.

By directly wiring the binding post inputs in parallel to the amplifier, 

the bottom octaves reproduced by the 8” Woofer blend smoother 

with the output than if an additional passive filter were used.
