I did not got your beat separation thing. What do you mean with it ?

Do you mean the 5050 CD HU?
You can't play dts files on it.

80 is a safe HPF cut off range in most cases and configs. If it's cut off at 120, then it is necessary that the sub is able to handle that frequency range comfortably.

Normally, a subwoofer is not exactly designed to handle midbass frequency ranges. So, it's always better to let the subwoofer handle the lows and midbass drivers handle the lower and higher ranges of mids.

Default Pio 4050UB HU query

I recently fitted a Pioneer 4050UB HU in my Scorpio. Quite strangely, I am unable to turn the HU off. The "Off" button is combined with the "Source" button - you have to keep it pressed for a few seconds to turn the system off. However, keeping it pressed is resulting in the Source changing to "USB-iPod" and not turning off. I've tried keeping the button pressed for varying lengths of time but no luck. The user manual doesn't say anything extra - just instructs one to keep the button pressed for a few seconds to turn off the HU.
Has anyone faced this issue? What's the solution?

Also:
Am unable to use my iPod Nano with this HU. I get a "N/A USB" error message. According to the manual, this implies:
"Old version of iPod -Update the iPod version.
OR: iPod failure - Reset the iPod"

I know it isn't the latter, because the iPod is working fine by itself and when hooked up to my Lancer's Alpine CDE9881 HU. Not sure about the version - I have a first gen Nano.
I am using Pio CD-IU50 USB to iPod wire to connect the iPod. The USB connector wire came with the HU. There is no separate port to attach an iPod cable to the HU - it has to be connected the USB cable. Any suggestions would be appreciated.

^^^ bro you can try to press and hold down the src button on the remote to turn off the deck. I think that should work shouldnt it?

OT: how much did the Pio CD-IU50 USB to iPod wire cost you?

Ok now I have a question about compatibility of JBL CS2104 / JBL GT5 402 with JBL GT5 A604 amp. Recently when I got my friend's car kitted at GLIX,Kolkata the owner of the shop Vinay Daga adviced us not to get the front speakers (JBL CS2104 ) powered through the amp (JBL GT5 A604) by giving the reason that the 4" speakers wont be able to handle so much power from the amp. So the situation now is that he has a 4 channel amp but only the rear JBL GTO 937SE speakers are getting powered by the amp. Experts please advice whether it is okay to connect the front speakers to the amp aswell or not?

Thanks in advance..

You can very much use the AMP to power them.make sure that the gain is set 30-40% compared to 937. I am using the AMP to power illusion 4 inchers.

Read my post Bobby Have already tried doing that, but it hasn't worked. Hence my query. Anyone has any inputs on this issue and the iPod one?

MRP is Rs.990, give or take. I got a package deal on the HU+cable, so can't tell you the exact break-up.

Navin, are you sure about these recommendation. I am asking because for most of the acclaimed brands like Focal and Dynaudio (6" Components) the frequence response range starts at 60 Hz.

Moreover for an active set up, the range for mid bass drivers start at 63 Hz in my HU (Eclipse CD7100).

Loss of accuracy in bass notes. I listen longer bass note which sounds like aberration. If I lower the XO point to 63, the accuracy of the bass notes increase.

Default Help please

Hello gurus,

It seems like my post has been lost in the gamut of recent posts here. I would like to make another request to the gurus here to please help me out in clearing my confusion. My detailed request is up on the Palio ICE thread on the last two or three pages.

Hoping to get a response.

Thanks,
-Ganesh

smaller drivers especially midbass drivers (high Bl/Mms ratio) reproduce bass more accurately than large woofers but they cannot reproduce high SPL at low frequencies and are usually mounted in doors with limited rear volume.

So if you are playing a lower volumes it may make sense to XO the midbass as low as possible (even full range) and use the sub only for the last octave or bass reinforcement.

At the other extreme if you want to reproduce Disco levels in the car a higher XO freq and steeper slope makes most sense.

Many HUs allow you to save multiple XO settings so you can set up different settings for different applications.

In a car the sub is usually in the rear trunk and the midbass is firing at your knees. At home all 3 speakers are in front of you. The difference in distance from your ear to the midbass and the sub is small. Hence at home you can get away with a high XO or shallower slope (I used to used a 6db/60Hz PLLXO with my system - using stereo subs).

Hi Sam,
Thanks for the response...sorry..had to go off on a hurried trip to HK, US / UK etc...now back.
Can you suggest who to take my GTO 301.1 to?

Ni Navin,
thanks for your response..the amp now seem dried up..will connect this weekend and see if this still plays

yes you can but they have to be islated from other fuses.

remember if you upgrade the fuse to 75A the fuse holder must be able to carry the current too otherwise that may melt
