At what reference level?

And yet another query-
What is known as setting the gains high on an amplifier, is it when the knob is more towards 8V or is it when it is more towards 0.3V?

Ideally the gains should be set at about 50%-70% so if you want to keep it simple start in the middle and turn it up if you find the volume too low.

As per my understanding it is when the knob is more towards 0.3V because you are increasing sensitivity of the amp.

Absolutely correct. The lower the voltage on the gain setting, the higher the gain of the amplifier is.

Okay, if in an amplifier, the gains are set high, would there be clipping at say 30% volume or normal listening volumes?

Also, how to activate the Subsonic Filter?
Does it activate automatically when LPF is switched on?
I am asking because my amplifier has it for both channels and the switch for crossover is only for- HPF-LPF-OFF

I have recently installed JVC AVX-836 HU (Without B&W, as this model is not available officially yet) in my Civic.

The only problem I am facing is the microphone of this HU is really bad. I have used HU with bluetooth (Blaupunkt MP57) in my Swift last year and it was really good but I am not able to use it the JVC. I have to literally shout, even then my voice is not audible to the caller.

This particular piece of microphone maybe defective or it might not be successful in this model of JVC.

Any suggestion guys?

Can I use other microphones with this unit? If yes, from where and for how much I can get it in Delhi ?

Thanks in advance.

@mukeshgoel, where have you mounted the microphone? Dumb question, but - are you sure the microphone is connected?

The best place for the microphone is near the visor. Where exactly depends on how the microphone and it clamp are oriented. You need to experiment with location and direction of the mic. A good place to start is where the A-pillar meets the roof near the sun visor.

Hi.

It is connected. If I shout then I am slightly audible to the caller and my voice is distorted like a cheap radio.

It is placed exactly where you are suggesting (where the A-pillar meets the roof near the sun visor).

By the way, I am using my Blackberry Bold 9700. It streams music from my phone to the HU so well. I am yet to try another phone.

You could try using another mic, as long as the jack is the same. I doubt if there is a problem with the mic, it could be just a loose connection. Try a JVC service center - even if it is not officially supported, they would be able to help you diagnose the problem.

Thanks.

Will try another phone first.

If unsuccessful, will try another mic.

Can someone please confirm are they normal mic or JVC has some special proprietary jack/pin ?

I use a Blackberry Torch (before that a Bold2) with a bluetooth Jabra and have had no problems.

Dear All,

I would like to know your opinion or choice of HU from the two units mentioned below. I cannot personally audition them as I getting them from US. Also I have narrowed my choice to these two after getting convinced that Clarion is a good brand.

There is not much of a price difference between the two. I don't know much about the technical terms hence this request. And I have attached the file showing comparisions of HU's where the below mentioned Hu's are featured. (From Clarion India site)



Clarion UK | CZ500E


Clarion UK | FZ709E

The FZ709 is disc-less, so if you want to play CDs, even MP3 CDs, you can't. Funnily, it also doesn't have a removable face plate, nor a rotary volume control. On the other hand, the FZ709 has a 24-bit DAC, which means better sound.

With Time Alignment, The DXZ786USB is a better choice, but alas it doesn't have Bluetooth. Tough choice!

What are the basic features that one should look for in an HU (~6-7k) if 1 sub and 1 amp would also be added in future? The initial setup would have 1 HU and 1 set of components for the front door. Later, say after 2-3 months, I would add an amp and sub also.

I've already shortlisted JBL's GTO608c but do not have much idea about what HU to go with. I really liked Pioneer's DEH-4190SD and Kenwood's KDC-X7013U for their looks but the price is on the higher side. So need a little help in selecting a good looking HU which would only be required to drive front components.

The car is driven with 2 occupants at max so no plans of having any co-ax in rear but would definitely want to add an amp and sub in future and hence would want the HU to be able to undertake such modifications.

When browsing the net for the HUs I get to see a lot of features but have no idea what all are really worth having in an HU.
