Symphony headunit...

...Does it have a subwoofer output or no?

Getting a port done to me cabinet to improve the low-end response too, but just wanted to know if the HU has a subwoofer output, considering the fact that Skoda also have a subwoofer in their inventory..

**mannyo** · 15-10-2005, 08:55

If its the same as the octy one, it has line outs. The connection is on the mini iso connector, and its the same connection as used by blaupunkt.

Mil · 15-10-2005, 09:25

This is the one I have...

The line-outs will be the speaker line outs, 2 for front, two for rear. Sub-out will be separate, sending filtered low-end signal only? Do you know if this has it?

Lummox · 15-10-2005, 09:27

No it doesnt have pre outs for subs or amps. Just line outs for speakers left and right and front and rear.

Mil · 15-10-2005, 09:34

Okay thanks

Nope you're wrong. You can buy a mini iso cable that provides an output. I know as I have one fitted to my Symphony.

I ordered mine from bluespot.co.uk

Okay thanks

So what price we lookin' at for the cable? And how would you make the connections?

£15 sterling, not sure how much delivery would be for you.

The cable plugs into the iso block on the back of the stereo, this then gives you your outputs for left and right channels, pretty much everything is plug and play, I'm no car hifi expert but successfully fitted my active sub in two hours including trim removal etc....

That's about 100 dirhams..not so bad.

So tell me, the signal that comes out of your subwoofer is purely bass & sub-bass, or is there a hint of low-mids in them? With purely sub-bass signals, you hear and feel nothing but bass, instruments and vocals shouldn't bleed through...

If they are purely bass signals, then it is what I think ISO stands for...a frequency isolator.

I stil stick by my statement that the headunit doesnt have any pre outs. You may wel lbe able to buy a line out convertor that plugs into it, but what I meant is it doesnt have phono outputs that you can connect to an amp.

No afraid not, ISO just indicates an industry standard, meaning if it has ISO connectors anything will plug into it that also has ISO connectors. The same that single DIN headunits are an ISO standard.

And im pretty sure the signal out of that lead it full signal and the Skoda/Blaupunkt active subs have crossovers built into them to filter out the unwanted frequencies.

Mil · 15-10-2005, 13:28

It's just a preamp cable dude. This is not what I need. Like Lummox has already said, I just found out from another source that the HU does not have a subwoofer out, which is what I need. With a subwoofer out, the signal that goes through is filtered at more than 12db per octave at about 120Hz, and gives off purely bass signals. This cable is only a preamp cable which you would use to connect to separate amplifiers from the HU to drive four full range speakers.

Oh it's that kind of ISO, as in International Standards Org...I know what ISO is, I do not know why it slipped through my head

Thanks Ross.

Lummox · 15-10-2005, 13:32

The Symphony doesnt have a sub out that much is true. But why can you run that full range channel to an active/passive crossover? Or set up your sub amplifier to sun at sub frequencies, most have this facility especially mono sub amps.

Mil · 15-10-2005, 13:45

The amplifier I have only has a filter. The basic principle is like that in live sound.

Say I've got a three-way system going, subs, mids and highs. To get these individual bands workin', I'll need a mixing console to send the stereo signal into a 3-way crossover, set the filters and take the outs from there into three different amps to drive a subwoofer, a mid-range horn and a big-a$$ tweeter. A 3-way cross-over works by splitting a normal full range signal into 3, bass, mids & highs, and filtering it steeply so there is no bleed from the individual bands into each other. The crossover settings will insure this. Some powered mixing consoles however will have a sub-woofer out, and through this output, the full-range signal has already been steeply filtered at say below 80Hz, to give only bass signals.

I need to buy a passive crossover. However, I can't find any here

I'm getting the cabinet ported to improve the bass response. It's alright as it is, but with the help of the acoustics of the car, I know the ports will help me reach the <50Hz realm...I'll ask them again tonight if they have a crossover though.

Again, thanks Ross

Lummox · 15-10-2005, 15:29

Something like that then would do inline with the sub wouldnt it? So amp gets full signal but only the sub frequencies go to the speaker

http://cgi.ebay.co.uk/100-WATT-STERE...QQcmdZViewItem

Or you could get someting like this..

And run that in between the headunit and the amps so the amps nly get thier required signals for their speakers.

It is unusal to amp tweeters on their own, usually you would buy a set of components and they have thier own passive network with them to give each speaker the correct sound. My Alpine SPX components however can be bi-amped so your can run all four speakers (two mids and two tweeters off a four channel amp).

Mil · 15-10-2005, 18:34

Well dude...

Had some two ports done to the cabinet tonight...but it totally destroyed the bass element. If I could I would use the Thiel-Small parameter guideline but I ain't goin' down that route. Was never really happy with the response of my Eminence woofer as well...it only gave me a low of 65Hz...

So I've ordered a brand new Earthquake subwoofer...Tremor XR12. Powerful subwoofer, looks good too. Click on the link to check it out:

http://www.earthquakesound.com/tremor.htm

The crossover I've found today is an 'Absolute CR100' subwoofer crossover, check out this picture:

With the new sub and a new cabinet design, I will have this crossover fitted in between the HU and the amp to give me on bass frequencies.

In pro sound it ain't unusual to have a separate amp running tweeters

The most powerful club system in the world is the Dynacord Alpha concept system. The subwoofer is massive and has twin 18"s, running 2000 watts, and the tops are 1500 watts. The tops alone need three amps to drive it, split signals for low, mid and highs using a speaker management system processor. The tops have twin 15"s, a massive mid ragne horn and two super tweeters. And then there's the subs which are driven with one amp...in effect, it's a four way system...believe me dude, it is huge..

Check out:

www.dynacord.com

Anyways, tomorrow I'll be taking my car in, and the woofer will be fitted in. I'll post pics as soon as I can.

Thanks for everything Ross.

Your welcome. I am by no means an ICE guru but i'm also learning a fair bit building up my system (only have about a third of the space to fill as you though

)
