How to connect subwoofer - Technics SA-AX530 Receiver

This subwoofer is probably powered directly from the amplifier and doesn't have an internal amp. The connections are probably the same type as for any other speakers. And, there are probably additional connections for the rest of the speakers. The connection on your amp is likely an RCA phono plug connector that sends low level signals to a powered subwoofer. To connect a passive subwoofer, one without a built-in amp, the main speaker outputs connect to the subwoofer and are then sent to the regular speakers connected to additional terminals on the subwoofer. You may need an owner's manual for the subwoofer to determine how it should be connected.

Connect the Subwoofer connection on the receiver to the LFE connection on the subwoofer.

The normal connection on the subwoofer is for connecting a full range signal, from which the sub extracts bass via its internal crossover.

Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

With everything connected correctly there could be a couple of possible problems:

1. If your receiver has on screen display capabilities, you may need to turn the subwoofer output "on"
2. If your subwoofer has speaker wire inputs/outputs, you could run speaker wire to it, then to your speakers & test if the subwoofer is working... hence verifying that the receiver has a function to turn the subwoofer output on/off
3. The cable between the subwoofer & receiver could be bad. Try another cable.

Good luck!

Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

I guess you don't have the owner's manual for this?
You can get it here:
MS907 Subwoofer manual
The manual contains connection info.

Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?

If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1

This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.


If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.

This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

deppending on the subwoofer, theres all kinds of converters, u can do this, take the subwoofer to a radioshack or call them and ask that u need a wire converter 4 example say rca converted into headphones & they will hook you up, saves alot of money 4 a say 15 to 20 doller item, and ur subwoofer will be blasting like no tomorrow
hope tha helps

if this is ao powered sub, that plugs into the wall, there should be no problems, if it is powered solely by the reciever it may work fine but be sure you dont exceed amperage on the subwoofer.
