Could someone please confirm this is safe for me to do please ?

Hi all

My dad has a EBS HD 350 Bass head you will be able to see it here http://www.bass.se/

In my house I can only do silent recrding basicaly I cant mic up a amp or anything like that because it would be far to loud for the people who live next door

I was looking at his Bass head tonight and noticed it has a balanced output XLR so wnt on the EBS web site on to the FAQ section and found that .......

Q6: Will I damage my EBS head if I use it without a cabinet; for example in a recording situation?   You may use all EBS bass head without speaker load, i.e. no speaker connected., except the new Classic T90 all tube head that should have a speaker load to avoid harming the tubes.



So my question is  would it be safe to run this through one of my mic pres on the VS700 and use it for recording ?

I have never done anything like this before so thought it best to ask you guys who will know :D

Thanks for all the help everyone

 Didn't have time to check their web site so I'll leave this to you to check out.
 Some amps have the XLR output pre EQ and pre amp meaning it's captured before you hit the the amps "tone"  so it's the same as using the bass direct like a DI Box. There would be no point in using the amp if this is the case. But sounds like this puppy has some switches and might be settings that send the signal post EQ. Then you will have the benefit of the pre amp and tone shaping. ( compressor? )
I have a Yorkville B 200 bass amp and the line out is post pre amp so the tone shaping and compressor sound arrives at the mixer.
It's a combo amp but if you plug a headphone dummy plug it shuts off the speaker for recording. Tube amps need a power soak or they are not happy without a speaker load, Transistors could care less.

The vamp I am unsure If i wil be geting it now....... I oayed for it but I have been tracking it and all it says is left origin country larnaca airport and thatts been like that since the 15th Ive contacted the people at the shop and all they say Is they will lok in to it they are being of no help at all. So think I might need to get my money back and get one from somewhere else

Anyways about the EBS HD350

How would I use this straight in to the vs700 then ? from the xlr to a line input ? Or another way from he Xlr on the ebs to what ?  Ive never done it before so I really dont know what to do.

Other people I spoke to over on gear sluts are saying it will work no problem http://www.gearslutz.com/...-head.html#post5817047

How would I do it then craig ?

Thanks

Try it if you'd like. I wouldn't do it that way. XLR out to TRS in. The 1/4" inputs on the V700R are TRS. Both are balanced. Read your Mic Pre owner manual and see if XLR you want to plug into is line level. And see if the EBS output is line level. You need to check these things now that you're hooking things up. Especially with low frequency instruments.

Hey again!

Thats it all sorted xlr to xlr on the balanced out put works like a dream just use the gain  to send the level going to the vs 700

It works like a dream and sounds awesome

Thanks to every one :D

Hi Norrie I see you are having some fun and games with your bass head. Firstly is there any way you can connect the output from that DI connection on the front to something else completely like a small mixer or something and just monitor the sound quailty to make sure the crackling is not in the bass head or it is in fact in the bass head. ie eliminate the VS700R from the equation all together. 

What sort of levels are you recording at with your VS 700R. Maybe you are clipping without knowing it. Are the input preamps in the VS700R being overloaded. Have you got the PADS switched IN on your VS700R? You may need to switch them in. Make sure no phantom power is being sent on the signal line you are using to connect to the VS700R. It should not matter but it might be causing some concerns. Are the compressors (on the VS700R) switched in as well. I would not have them switched in necessarily. They might be clipping themselves. They are on the digital side of things too.

Where I teach sound engineering at TAFE we have a Trace Elliot bass head with a DI on the front too and it sends some serious level into our console. Like well over +4 dbu for example. We have to pad it down heaps just to stop any overload.

But the main thing I would do first is take the VS700R out of the equation and make absolutely sure the signal is totally clean from the bass head. Try switching the EQ IN and OUT too as that might be causing siome grief. I suspect the signal is clean leaving your bass head.

Having the Pad OUT and the fader down low is NOT the same as having the PAD IN and having the fader up higher. Please try switching the PAD IN. You will loose 20 db of gain but bring the fader up to make up for it.

The PAD is before the very first stage of pre amp.

Hi Norrie,  I jumped over from the other thread.

Looking at the manual for the HD350, on page 14 there is a block diagram of the amp signal path and it shows where the XLR output is wired in.

So using this info, here is how to setup your sytem...

1. Connect with XLR-XLR as I said befor, make sure phantom power is OFF.
2. Turn master volume on HD350 right down (off) this will mute the speaker output.
3. The buttons next to the XLR output, select Post-EQ IN and Gnd Lift OUT
4. On VS-700 channel, select Pad IN, set Gain to approx mid position, set chan fader to 0 (somewhere near the top)

Connect your bass. Start hitting the strings.

5. Adjust Input gain on HD-350 so that peak light just starts to flash, then back off a little.
6. adjust the input gain on VS-700 to give -12 to -6 peak level.
7. Stop playing, listen for noises like humming, buzz, radio pickup, hissing, etc.  If you're getting these, press the GND LIFT button on the HD-350.  The noises should stop.  If you're NOT getting noises, LEAVE THE GND CONNECTED.

That concludes the connection.  If you adjust the controls on the HD-350 to change the sound, maybe using the built in compressor or EQ, then use the GAIN on the VS-700 to adjust the level.


Your other amp should connect in exactly the same way.


The important thing to note for the HD-350 (and infact most amps) is that the "Line out" on the back and the XLR on the front are NOT the same. The XLR is intended for exactly what you're trying to do. The Line Out however is connected AFTER the main volume control and is intended as a feed to further power amps, (or other equipment where the level is required to follow your master volume control).
