How to connect the amp,too many inputs and outputs

Hi,
I really hope u can help me,i have 2 basic speakers with connections in the back for the amp leads to go into,but i am really struggling with what wires i put into the amp and in which connections and then really, really struggling with which connections i need to come out of the amp to go to my speakers.
I have a Carlsbro 150w power module and it has an Output hole of which im guessing is where the speaker connection goes,but on the front of the amp i have 6 channels,each with a hole which is black that says HIGH Z,and also a red hole that says BALANCED LOW Z,and next to it i have two buttons with REV and FX.At the other end of the amp ,ive got another red hole that says REMOTE SWITCH and 2 black holes that say EFFECTS ,SEND and RETURN.Do i need these? I just dont know where to put my output line from my mixer to the amp.PLLLLLLLEEEEEEAAAAASSSSSSEEEE HELP.Im tearing my hair out.

I'll try to help you step by step from your question. My answers will be in all caps. Here we go.

I really hope u can help me,i have 2 basic speakers with connections in the back for the amp leads to go into,but i am really struggling with what wires i put into the amp and in which connections and then really, really struggling with which connections i need to come out of the amp to go to my speakers.
I have a Carlsbro 150w power module

(THIS SOUNDS LIKE A PA AMP AND NOT A CONSUMER STYLE AMP, IS THAT TRUE?)

and it has an Output hole of which im guessing is where the speaker connection goes

(IF IT IS LABELED OUTPUT THEN IT IS INDEED A SPEAKER OUTPUT CONNECTION)

,but on the front of the amp i have 6 channels,each with a hole which is black that says HIGH Z,and also a red hole that says BALANCED LOW Z,

( THESES ARE MICROPHONE AND OR GUITAR INPUT JACKS AND MOST OFTEN YOU WOULD USE THE HIGH Z (meaning impedence) INPUT FOR A MICROPHONE

and next to it i have two buttons with REV and FX

THESE ARE FOR REVERB AND EFFECTS CONTROLS OR INPUTS. YOU DON'T NEED THESE FOR JUST A VERY BASIC SETUP.

.At the other end of the amp ,ive got another red hole that says REMOTE SWITCH

DISREGARD REMOTE CONTROL SWITCH JACK

and 2 black holes that say EFFECTS ,SEND and RETURN.Do i need these?

DISREGARD THESE TOO

I just dont know where to put my output line from my mixer to the amp.

IT WILL GO INTO THE BALANCED LOW Z INPUT, BUT IT MAY ACTUALLY BE TOO HOT A SIGNAL(signal strength too high), LOOK FOR SOMETHING LIKE A TAPE INPUT OR SOMETHING LIKE THAT ON YOUR FRONT PANEL. IF YOU DON'T HAVE ANYTHING LIKE THAT THEN YOU MAY NEED TO USE AN ADAPTER DEVICE THAT WILL KNOCK DOWN YOUR SIGNAL STRENGTH TO THE RIGHT LEVEL FOR A MICROPHONE INPUT AND THEN PLUG IT INTO THE BALANCED LOW Z INPUT.

PLLLLLLLEEEEEEAAAAASSSSSSEEEE HELP.Im tearing my hair out.

HOPE THIS HELPS. GOOD LUCK

The speakers have a jointed positive on one side and a jointed negative on the otherside. each speaker ahs 4 terminal connnections. 2 pos and 2 neg. How should i wire these to a single + - input amp?


A single mono power amplifier has usually one output to the speaker and this output can be connected to 4...8 Ohms speaker. If you have two speakers, they can be connected parallel or serial.
In my opinion they should be connected serial because in this case the resultant impedance would be 2 times more than one speaker's one.
The connection:
We have speaker(1) with poles 1+ and 1-, and speaker(2) with poles 2+ and 2-.
We have amp output with poles amp+ and amp-.
Connect speakers 1- with 2+ together,then connect amp+ to 1+ and amp- to 2-.

The "output" is two RCA


hi,
normally in any amplifiers or pre amplifiers the RCA sockets used only for pre input and output. for speaker out always there will be binding post or speaker sockets, u can connect the pre amps RCA output to ur power amps input. there will be seperate connector for speaker connection in ur power amplifier . You didn't specified the make and model number of ur amplifier and pre. need any further help feel free to contact.
ok

I want to connect YST-Sw1500 sub woofer to the AX-596 amplifier .How can I do the connections .


on ur subwoofer u will see HPF output, connect this output to MAIN IN of ur power amp (first remove jumper between pre-out and main in from ur power amp) connect pre-out of ur power amp to input 2 L&R (Left is also for mono input). the HFP selector switch will cut off 80Hz or 100Hz to the main input depending on the position enabling u to have high frequency sound on your main speakers. connect the speakers to the main output terminal of ur power amp. do not connect speakers on the woofer ouput.
make sure u are using the right impedance speakers. do not switch speaker impedance selector while the unit is on.

I have 1 center channel pre-out on back of my kenwood receiver. how do i hook it to the inputs on onkyo m-282 amp and then to center channel speaker?


Unfortunately can't connect it that way. The pre out is only meant to go directly into an amplifier that has all of the same inputs (front/rear, center and surround), not a standard receiver. (Pre amp to amp only, not pre amp to receiver) If your Onkyo doesn't have all the same inputs as your Kenwood preamp has outputs you will just use your standard left/right outputs from the Kenwood to your Onkyo input (CD, Tape, Phono,DVD etc) then use the outputs (front/rear, center and surround) from your Onkyo receiver and connect directly to your speakers..

I don't have any instructions so i don't know how to hook up my speakers and the t.v for surround sound i have a carver avr 100


You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

PV 2600, couple years old, light usage. Connected to two PV SP3K speakers. One channel started to cutout somewhat but not all the way, Switched a few input cables, swapped L&R. Then whole amp shutdown....


Hi..

I've worked on similar units.
Things I'd check first :
Dust in the unit.
Weak solder connections /crusty debris stuff on the input jacks or output terminals
Any flex cables soldered in tend to be a problem on peavey amps I resolder all those contacts.
Checking the amp w/o a load IS NOT a good suggestion.
What style output connections are you using?
1/4 inch, binding post, or Neutrik style?

Marantz PM-48 connecting to TV


look on the back of the TV and there should be L/R audio outputs (white & red), connect this to a spare input of your amp via a connecting lead eg. AUX or any other input except PHONO.

hope this helps.

Using a tube pre amp with my CA Azur 640A?


There are many answers to your questions but Ill have a go with the basics...
Audio connections should be matched.... its called Frequency impedance,.... to get a signal along wires or cables (or Fibre) the Impedance of the cables and wires must be matched to the device they are connected to transfer the signal along the cables without distortion...

Manufacturers provide many sockets on the input side of amplifiers and preamplifiers to allow the consumer to connect various devices of different impedance.

They label these inputs like CD, or Tuner, or PHONO etc etc,

That means if you have a CD player it must be plugged into the CD input socket then the impedance will be correct and the sound will transfer along the CD cables correctly, without distortion..same with the Phono input etc...
You will find on the sound output to the speakers terminals are also labelled 4-6ohm, or 8-10ohm, these are the impedance expected for the coil ratings of the speakers them selves and its important to get the correct speakers to the correct out put terminals...

In your case all you have to do is follow these simple rules and all will be well....you say you have a squeeze box well there probably isnt a port labelled squeeze box so you need to experiment and try out each input port for the squeeze box to see what input gives you the correct sound output...Watch the Phono inputs as these are very sensative to input sound levels and must be treated very carefully as they have a double stage of sound amplification and as such you need to have the volume right down when connecting up the Phono inputs then increase the volume carefully after the cable connections are completed.

If you follow these rules then all will be well,,,,there is no difference if the Pre amp or Power amp is valve or transistor or FET or has IC outputs to the speaker the same impedance rules apply..just treat it as a box with input and output terminals and all the impedance will be taken care of for you...if you read the lables...

You need to connect you signal source to the Preamp inputs the out put from the Preamp connects to the power amp input then the power amp output goes to the speakers. this is a basic configuration for sound systems, there are other variations but are outside this discussion.
