Guide on how to setup the JBL ES250PW
Considering the sub will be used primarily with a AVR. I will only discus this
A very simple process to intially integrate it
For the Initial test - ""Do not use the Wireless"" module as yet
Run an RCA from the LFE of the AVR to the LFE input on the sub.
Make sure that the Sub and AVR is turned off - this is to ensure that there is no loud noises when initial RCA contact has been made.
Set the level of the subwoofer on the plate amp of the subwoofer at 30% (9 oclock or 10 oclock position
Do not fiddle with the phase 0 -180 as yet
Crossover on the sub plate amp set it as maximum 150hz
Switch on the AVR and the JBL Sub.
Do not use the AVR's calibration tools as yet.
Enter the setup menu
Use manual setup and set the front speakers as small, if you have other speakers such as center surrounds set them all on small.
And Subwoofer as "YES or " ON .. depending on which AVR you have, since they all have different terminologies
Set the crossover on the individual speakers at 80hz or if you AVR does support setting individual speaker crossovers. Set the crossover of the Subwoofer on the AVR as 80hz. This will automatically set freq of all the speakers at 80hz and anything below will go to the subwoofer
Put on a bass heavy track of your choice. Preferably an audio track which has a lot of bass freq in the 40 - 80 hz range "British Dubstep" tracks have a lot of bass beats through the entire song. So a good option for initial setup to see if everything works.
You may find that there is no cannot hear or feel the bass.
At this point move the phase knob on the subwoofer plate amp on the rear to see at which position you get the most amount of bass.
"" This would be better if there is someone else in the room and you are sitting in the listening position "" you will find a drop or gain in bass output with your counterpart rotating the knob. Stop when the bass output of the subwoofer is at its loudest
HOWEVER
Subwoofer room placement is very important. with incorrect placement you may find that there is a null in bass where you are sitting and a peak in the middle of the room. you will have to fiddle with proper placement. Use the Subwoofer crawl. Google it or a youtube video - Alan loft from Axiom Audio has explained it very well
Once the subwoofer is position at the optimum place. you can then go ahead and use if the wireless module.
Check if it gets signal , if it does not work due to interferecne from other equipment in the house Change the channels on the wireless module and plate amp on the subwoofer till it receives a signal.
You can now. use YPAO, Audessy etc room correction for proper integration with your speakers and room.
However irrespective if you have large FS or bookshelves. Always set the other speakers as small or cut of fequencies going to the speakers. this is to ensure both the speakers and sub are not playing the same frequencies. this will avoid an overlap of freq of both the speaker and sub playing the same freq.
Once integrated ....
ENJOY YOUR NEW TOY
