Icom IC-7000

Post by LA0GE »

Hi all.
I'm new to this voodoo audio and infact I'm not going to do any mods on my IC-7000 either. However my question is this:
I am using a PR-40 with it. It has a very LOW modulation on FM.
Which Behringer box(es) do I need to get this combo come alive?

Best regards
Bent

How Low can you go?

Howdy Bent!!!
Welcome to the Voodoo Forum.

Yes, the PR-40 does tend to have a Low output.
Almost as low as the EV RE-20 mic.
A Mic Preamp would probably help allot.
As far as which one, that is a matter of preference.
As far a rack type gear goes, the MIC-2200 is probably the most inexpensive and also the best one for what you want to do.
It does not have a problem with RFI and is very popular.
You could also try some of there smaller units, but We're not familiar with them as to there performance.

But is this problem only on FM?
How is the Modulation on SSB?
If it is only FM, then maybe there is an adjustment inside the rig, or in the Menu to increase the FM Mic gain or the FM Deviation.

Hei.

Ok I have ordered the Mic-2200. Can I use this for 2 radios or goes both channels to one radio?
Whats the easiest way to connect it to the Icom? IBOX?

Ok cool my first rackbox. What box comes next? Or will this Mic-2200 be good enough for me? I have listen to some of the demos on W2IHY site and likes the sound of the compressor alot. Makes the audio sound so strong. Also the noise reduction is great.

I haven't heard my audio, but with compressor almost full and micgain full, I have got good reports on SSB.

Hej!

No, You will only be using one channel on the MIC-2200.
The other channel will be empty.
You could run two radios from it, but you would need another microphone for the second channel.

That should be enough unless you want an EQ or something.
But then you will start adding all kinds of units after that! hahah
We think the IBox would be perfect for your radio.
That way you can adjust the input level to the mic jack, and also it gives some isolation.

If you like the W2IHY stuff, you might want to go that route instead of the rack stuff.
It also has a mic preamp in the eq.
Then the W2IHY EQ-Plus has all the other stuff with it.
It is just on the expensive side.
For what you pay for that, you could get all the single units from Behringer to do the same.
This is where personal preference comes into the decision.

For example, the Behringer VX-2496 unit has a mic preamp, an expander (noise gate), a compressor, a small eq, and a de-esser. It also has a side chain to insert the PEQ-2200 5 band Parametric EQ.
These units are inexpensive and give you allot of adjustability.
We used to run this setup on AM here and it worked excellent.
Now of course We are at the Extreme end of the units! hahaha!!

Hope this help, Bent.

Ok with W2IHY. I don,t know anything about his units exept the same that you mention.... the price. Also they look boring. I am sure they work great after reading alot of reviews for his products.

I will wait for the Mic-2200 to arive and see what is does.
I'm quite sure this isn't the last box. HI HI
Good news that the 2200 will work on two separate radios.
However my next mike will probably be either the PR-780, Behringer B1 or Marshall MXL-990. The MXL looks cool.

Nice to finaly have taken the step to better audio. I have always been interested, but never could justify the cost.
Have been visiting your site many times.

Thanks for all info for now. I'll be back when the 2200 have been connected.

Best regards

Hi again

Things have a tendency to (as we say in Norway) take off.
I have not received my Mic-2200 yet, but it's comming in a couple of days.
I have jsut bought the MXL-990 mike. Would this be better for the IC-7000?

Can I use the cables for the PR-40 into the mic-2200 and another XLR cable from the PR-40 to the Mic-2200 or do I have to use an IBOX?

Would the EX3200 be a good choice for my next box? It sound great.

Sorry for all questions but i am a total newbee.

Best regards
Bent

Howdy Bent,
I have just bought the MXL-990 mike. Would this be better for the IC-7000?
mmmm....well the MXL-990 is a condenser mic.
You will notice it has a WONDERFUL sound!!
But, you can hear everything in the background also, condensers are very sensitive mics.
There are allot of people running condensers that can get away with it.
If you don't have allot of background noise We are sure it will work fine.
Sometimes though they have a tendency to be real bassy without the use of an eq.
You will just have to try it out in your application and see.
Can I use the cables for the PR-40 into the mic-2200 and another XLR cable from the PR-40 to the Mic-2200 or do I have to use an IBOX?
As far as the connection to the IC-7000,
We have never had one here, so it will be guessing here.
You will probably need to use the I-box between the MIC 2200 and the IC7000.
It doesn't matter which mic you use, you will still need the I-box in between whichever you choose to run.
We don't think you will be able to turn the mic preamp low enough to not overload the Mic Amplifier input on the IC-7000.
Try it and see.
Would the EX3200 be a good choice for my next box? It sound great.
No, dont think that would be the best logical choice.
The thought here is that an EQ would be the best thing to get next.

Hei
Ok one more question....
Is there any Behringer item I can use instead of an IBOX or is IBOX the best to use?

I am going to order the PEQ-2200 now.

Is it best to feed the icom through the mic input or via the acc. input on the back?

Best regards
Bent

Hej Bent,

The Ibox is probably the best for the price.
As far as where to feed the IC-7000,
Never having owned one, that is a good question.
Anyone out there played with the Mic input on the IC7000?

You will have to use the Ibox or some kind of Line to Mic level converter going into the front mic jack for sure.

Some units receive Line level audio when going into the ACC jack in the back.
If this is the case then you would not need the Ibox.
But unfortunately We don't know.

I would got through the ACC Jack.

If nothing else, you well by-pass all of the audio filters the the mic input has to offer.

I run through the ACC jack on my IC-718.

Hei Peter.

Nice to see other Scandinavians here. And yes I would gladly give Mike some Norwegian lessons.

Ok, I have connected the MIC2200 to the mic input of the IC-7000. I did it just to see if it would work. It did.... sort of.... mic preamp is working, but there are no difference when I use the EQ on the 2200. I can't get the Heil to sound better than the stock mike straight in to the rig.
I hope the answer is that I have to connect it to the Acc jack in order to get it to work properly.

Ok Mike.. ha en fin dag.

Med Vennlig hilsen (MVH)
Bent

If you go through the Mic input, you are running through the radio's preset microphone filtering.

It will roll-off everything your are trying to do to inprove your audio, and do it's best to keep you sounding like a DX'er... and we can't allow that!

Try running it through the ACC jack.

Depending on the Circuitry of the ACC input, we agree with Bow.
Also, the mic EQ settings on the 2200 is very minimal.
You might need something with a little more adjustability.
Basically all the mic pre is going to do is to correct the original problem that you were having with mic gain issues on the PR-40.
For adjusting the SOUND of the mic, you would need an EQ with more adjustability (ie. more filters).
The EQ on the Mic-2200 is just one filter and can only adjust one center frequency at a time.
OK Bent, Du har en bra dag också.
Hälsningar,

I will try to sneak up behind the 7000. As I told you I'm a total newbee with all this stuff. Just to make me feel that I'm investing my money in the right way, I received my MXL-990 today and just swaped it with the PR-40. The result?!? well the MXL gave no modulation at all.
Makes it easy to explain my wife why I need all this instead of the original (working) mike.
Should I use mike or line? And why doesn't the MXL modulate?
Is the DEQ2496 a good choice for EQing? I remember you mentioned the peq2200 but I would like to get a new unit.

Ok a lot of newbee question.

Mike, try to say this fast.....

You must use the MIC position, and the condenser will also need the '48V' button pushed in on the MIC2200 to supply the condenser mic with the voltage to work.
s the DEQ2496 a good choice for EQing? I remember you mentioned the peq2200 but I would like to get a new unit.
Yes the DEQ2496 is an excellent choice, but rather expensive and kind of complicated.
But it is a great addition because it has most of the other boxes you would need in it as as an All-in-One type thing. It has a Parametric EQ, a Graphic EQ, a downward expander, a compressor, and a multi band compressor.
The peq2200 is just an analog parametric eq, very simple and very inexpensive.

Hey Bent,

If you are interested in running through the ACC jack, here is the pin-out for the IC-7000:

Image

Pin # - Signal

2 - Ground
3 - Push To Talk
11 - TX Audio Input
12 - RX Audio Output

Case - Cable Shield
Connect all grounds for PTT, TX Audio and RX Audio to pin # 2

Ok.. now I have connected everything to the back of the 7000.
This is the setup.... PR-40 or MXL-990 into Behringer MIC2200 into the back of the 7000.
I doesn't work properly. I have to turn the micgain on the 2200 almost to max. It doesn't sound good, infact the originalmike sounds much better.
What to do next?

Best regards
Bent

Hi Bent,

Noticed no postings for a while and I am interested in finding out how you got on with the 7K and your rack.

I am running a 7K with a PR-20 into a UB802 mixer, then into a Multicom Pro-XL MDX4600 to downward expand, and then into a GEQ3102 EQ. Then I go into the good ole EX3200 wired for that Voodoo Audio and I then go into a MDX2200 to compress.

It all goes into the Acc socket on the back of the 7K and I am getting some fantastic results.

I run at full TBW WIDE of Low 100 and High 2900.

What I have noticed is that by running the rack through the Acc Socket the Mic Gain control has no affect on the Audio level, however the Compressor does although I do not run with compression now.

I get a lot of comments regarding the Audio so I must be doing some thing right. Having said that though, I have not yet spoke to any other Audio Guru's who may tell me otherwise.

I think the weak links in my Rack are the UB802 and the GEQ3102. I am in the market for a Mic Pre-Amp and Parametric EQ.

Regards All

Andy (G7VOT)
