hi

Have 3 questions :


1) When i turn on the amp with the gains all way down i hear a "CLICK" noise from the speakers, it is normal ?

2) Alfer 6 hours of normal use, i turn off the amp ,and accidentaly i touch the AC metal plug of the amp ,and it gives me electric shock !!!

3) I just update my XTI-1000 and i notice the display doesnt  show me the voltage
of the AC wall in the diagnostic mode.



thanks

Answers:
1 / Probably a small click if you are really listening for it.

2/ This is normal - there is still AC stored in the Caps of the PSU - These should discharge after a few seconds. I have had shocks off Itechs in the past doing the same thing.

3/ There is not an option to get the A/C line voltage displayed - The front panel will only show a 'Lo-Line' fault if the AC is out of range.

Cheers

Thanks Rob for the answers


But before i update my xti , it displays the AC voltage (like 221 V or 222 V ) in the diagnostic.

When the amp was released it was released with a very simple firmware and there was lots of free memory space for extras. To get all the code into the amp that is needed to do all the things it does, via the software, a lot of that memory space was taken up with necessary code.
It basicaly came down to this: Would we rather the amp tell you what AC line voltage it is connected to or provide an exter filter or two in the the EQ section. Since the amp already tells you if the AC line is low or high we opted for the more useful items. smile.gif

Oh

im a mobile dj so the ac voltage was useful for me  sad.gif

can i go back to the old firmware again ?  sad.gif

Or you could go get a multi-meter and have the best of both worlds! tongue.gif

Get your self a power conditioner with a voltmeter like furman if you do not want to spend too much this http://www.furmansound.com/products/pro/pw.../_merit/m8d.php , they also have more expensive conditioner as well if you are welling to pay more , but if you are interested only for the voltage then find the cheapest one :-)

Howdy,
  Just an FYI about power conditioners or power strips being used with Power Amps.

If you plug a Power Amp into one of these, it may trip, especially if the Power Amp
is being ran under a "Heavy Load" as in Subs!

Because of this, I only plug my Power Amps directly into an outlet which supplies good solid power!
Most AC panels today have 20 amp resetable circuit breaker's, even though the outlet, is a 15 amp outlet.
The majority of Furman's and power strips in general, have a light duty 15 amp breaker,
which is meant to pop easily for safety!
You can get a 20 amp version of Furman's and others.
Of course the 20 amp versions will also have a NEMA 20 amp plug, which will not fit into a 15 amp outlet.

My CE4000 on Subs, will pop a 15 amp outlet strip every time! Fo Get about it!
However, IF your Power Amp is being used under a "Light Load" for say Top Cabs or Monitors,
then it may not trip and you will be ok..
Just make sure and check this out with YOUR system before you hit the Gig,
no one likes surprises in front of a crowd!

As I said, just an FYI.

Later,
    Bud

Hey Bud yes i do understand but if he does have only one xti 1000, a mixer and two turn tables i would not be too worry unless is going to two ohms road, in your case a CE4000 on sub (6) hee hee draw a bit more current, and if he does pop the circuit breaker no sweat (not in front of a crowd :-)  )just hook up the amp to the regular outlet as usual and the power conditioner will still give you the voltage and the mixer and whatever else will still be protected :-)

Howdy Stephane,
As I said, it was just an FYI, so DJ-MK knows that the possibility of a Power Amp tripping a 15amp Furman or outlet strip does exist.
Especially if other Equipment besides the Power amp are also plugged in together.
As you and I both have said in our responses to DJ-MK, due to his setup it may not be a problem at all.

A standard practice when deciding on exactly what Power requirements are needed to properly power your equipment, is to add up the AC Power draw / amps, of all equipment that is to be used.
For myself I want a minimum of 60amps but prefer 100amps, for FOH and Backline.
That does not include Par Light trees with dimmer paks.

QUOTE
XTi 1000, AC Power Draw specs.
Line current, amps Load At idle, 0.62

1/8 Power Pink Noise, Typical of program material just at clip.
8 ohms per channel:  4.60 amps
4 ohms per channel:  7.44 amps
2 ohms per channel:  11.56 amps

1/3 Power Pink Noise, Typical of program material with severe clipping
8 ohms per channel: 6.78 amps
4 ohms per channel: 11.31 amps
2 ohms per channel: 17.54 amps


For DJ-MK it would be all of the equipment he uses, as in Mixer, Turntables, Lights, Power amp (see above)
and anything else that he did not mention.

For what it's worth DJ, I have never had a digital AC power display and I have been setting up Weekend Warrior,
Live Sound systems for 30 years!
I've used a Digital Voltmeter (DVM) when checking power.
You will be fine without this option.
As you can see from the Power Draw specs above, it takes SEVERE Clipping
at 2 ohms to appraoch 17.54 amps.
Best is at 8 ohms per channel.
What are your speakers rated at?

Have fun and enjoy your new XTi.
