Wiring Bins

[rictic 0]

if i want to wire my bass bins with my tops what is the best way?

i have 2 amps but no active crossover. the bins have a crossover in them (peavey the ones i will be using same imp and wattage as tops) i also have an extra amp output on mixer.

can i just use the amp output to my other amp and will the subs just play the bass or do i need a xover first?

if i link the tops to subs will the passive xover seperate the bass until i can afford a decent active xover?

 

dont wanna blow the amps

all spkrs 350w rms 8ohm

amps

1@1000w

1@800w

cheers

If you use one amp to power your bass bins then yes you are correct that the passive crossover will feed just the bass signal to those speakers.

 

If you use the 2nd output from you mixer into your second amp and feed this to your tops then they will receive the full signal (including bass).

 

Another option if your amps have this facilty is to put them to single (mono) output and use one for the left and the other for the right channel and feed your tops from the bass bin crossover (top) output.

do you mean use the mono bridge facility? or just send one output from mixer to each amp and use one output from each amp to bass bins?

 

if i use the mono bridge i have to be careful as i will be sending the full amp power to the spkrs @ 4ohm as they will be in paralell, if i am correct. that will be 800w to one side and 1000w to the other. or can i limit this by the main controls on the amps without doing any damage.

 

also if you pm me your number can i call you just to get it right in my mind that i am using the correct connections. 2 blown amps will cripple me lol.

Yes you would need to use the bridge option and then control the output from the pots. The reason for this (if you decide to use this option) is that if you run an amp in stereo mode without anything connected to one of the outputs it can do harm to the transistors.

 

Also in bridge mode you may have to use a different output connection to your normal (stereo) ones.

 

This is only an alternative option because you may find that using one amp for your subs and the other for your tops works well and produces great sound.

What i would do is use 2 amps,have an amp and eq for the tops then a crossover and amp for sub/subs

 

What you need to do is make sure you get the lows,mids,highs to the tops and the bassline to the subs,which a crossover comes in handy look on htfr website at speaker management.i hope this helps,damo

Just about every (half decent) amp when running in stereo mode should be capable of running one channel on its own.

 

Also, most amps when in bridge mode only make use of the channel 1 input and feeds it to both of the outputs (with one channel reverse polarity, thereby making the +ve terminal a -ve) The second gain control is either redundant or in some cases used to feed an audio signal out of the channel 2 inputs for providing signal to other devices. You need to check your particular amps manual for clarity

 

Another option if your amps have this facilty is to put them to single (mono) output and use one for the left and the other for the right channel and feed your tops from the bass bin crossover (top) output.

 

Are you suggesting parallel mono or bridge mono? I'm assuming bridge given your next post but it's important to be clear as parallel mono will not yield any extra power to the cabs, effectively leaving 2 channels completely unused.

 

 

 

To the original poster, personally I'd use both amps, if ythey have the facility i'd plug from mixer to the first amp inputs and then (if they have dual inputs for each channel) take a feed from that amps inputs to the second amps inputs. As the inputs are parallel wired they are also outputs and can be handy for taking off signal elsewhere. This way you'll get a decent amount of power to the subs and the tops. You can balance the sound using the amp gain controls.

 

If you say what amps you're using it might be easier to make recommendations. I'm not a fan of amp power being quoted as 'a 1000w amp' as it doesn't really say anything. Channel outputs at rated impedance is whats needed e.g. 500w at 4R or 350 at 8R, etc I suspect your 1000w amp is 2 x 500w at 4R. If your subs are 350w at 8R then they'll be fine.
