Jet sound equalizer js 214 wire color code

Black wire is ground, Red with 5a fuse is hot. Green/black is L Ground BTL, Grey /black is right ground BTL, the RCAs are left and right low level inputs. Then there is the 5 pin connector. It has a red wire for +12v, two black wires for input grounds, a green wire for left Hi input and a gray wire for right high input. If you install using traditional common ground high level, then you don't used the two BTL wires. Just connect the wires from your 5 pin connctor. If you use the low level RCAs for inputs, then you only need to connect the red and black from your 5 pin connector.(Plus the main red and black) Make sure the switched on the bottom of your EQ are set correctly. COM for common ground and LOW for RCA input or High for Green/Gray wire input. If you are using a floating ground the select BTL and connect the two BTL wires to the floating grounds of your stereo. There is also a line input adjuster so you can adjust your input sensitivity to match your reciever. I have the owners manual if you have any other questions.

Hi i just got a ava1202 boss eq it didnt have instructions this eq has rca inputs and high level speaker inputs can i use this eq with out an amp can smeone plz help me thnk u

Yes you can use the equalizer without an amplifier. That is what the high level speaker inputs are for. You simply take the positive and negative from a speaker and hook it up to the positive and negative high level speaker inputs on the equalizer.

Connect active subwoofer to Studiomaster Walkabout

You CANNOT have a stereo set of RCA jacks "wyed" into a single XLR mono input.

The RCA output drivers will "fight" each other. Some things will appear to work, but give poor performance.

You could make a rudimentary passive mixer by putting a series resistor say 1K ohms from each of the RCA's to a common UNBALANCED input of a subwoofer.

The XLR is balanced so that would not really work unless you also have an unbalanced input on the subwoofer.

The right way to do this is to get a cheap two input mixer that has EQ with it and mix your two mains before sending to the subwoofer. You want a little mixer that also has balanced outputs (XLR or TRS) to send to the subwoofer.

UNLESS the subwoofer has EQ in it, you really need to have an EQ in the little mixer so that you don't send high's to the subwoofer... They don't like highs and the sound will suffer.

I am keyboard player and i want hook up an equalizer to the system where do i hook it up to

If you're only using the keyboard, connect the keyboard output to the EQ input, and EQ output to your amp.

If you have multiple instruments and a mixer, run mixer output to EQ input, EQ output to amp.

More info, let me know.

How to install a 7 band boss eq with no high input jacks

If you are using the low input to put high input in you can use a 22k resistor and a 10uf capacitor connected in series to the plus side of the speaker wires. This will bring down the signal level from the speaker to low input level and you will have a nice distorted free music.

Need help connecting my eq to my system.

You will want to connect all of your devices to the pre-amp or receiver, then connect the outputs of your pre-amp/receiver to the inputs of the EQ. Then connect the outputs of the EQ to the inputs on the amplifier or receiver. If you give me some model numbers, I would be able to tell you exactly which cables go where.

Fostex mr16 eq/presets

In short - No. The Eq menu is the only way to affect the frequency levels on the inputs, but if you select stereo buss and listen to the inputs, you can hear the effect of each Eq on the relevant input.
