Hi guys

Just received my new 7500 and it sounds pretty good, plenty of power. When I intially turn the amp on it takes about 25 seconds for the amp to actually come on. Is this normal? Im using a onkyo 885 pre-amp and sony EP9ES for ht bypass and didnt have this problem with my B&K 200.7 amp.

Thanks in advance for any Help

PS The amp has a slight hum

My 7500 does the same thing for the first 30 seconds or so. It puts out sound before that but the blue light only comes on after 30 seconds. Outlaw says it is a normal startup sequence. Is the hum from the amp or from a ground loop? I have mine powered by an APC H-15 power conditioner and it is dead quiet. It probably does not need the power conditioner but the absence of the ground loop possibility is great.

Thanks for the response. I have a monster powercenter 3500, which the amp is plugged in the swiched outlet of the powercenter. The hum I hear is only when I'm by the amp. I might try powering up the amp thru my preamp 12 volt switch. Might give outlaw support a call

The amp sounds very good, not as smooth as the B&K a little more in your face. For the price, the 7500 is hard to beat.

About 2 years ago I had an xpa-5 and compared it to the m2200's and imo the xpa-5 sounded brighter.

Look in the 7500 forum threads as I seem to remember some posts about vibration in the case causing some humming sounds.

Check out this thread in the 7700/7500 forum.

hum with 7500

Will check it out. Thanks

Thanks for the info.

I am also a new owner of the 7500. I have no ground hum or buzz. My setup is dead silent. Only thing is that unless my receiver is turned on, the amp by itself causes a noisy hum. When the receiver is on and the timer "clicks" on, the Outlaw and everything else is dead silent. I have a Monster 3600 powercenter. Should I hook a ground wire between the Outlaw and the Monster powercenter? The powercenter also has a ground hookup.

Thanks

P.S. I love my new amplifier. It's huge and very detailed in sound. Makes my Onkyo 906 dull by comparison.

If you're not having problems with the system in it's current configuration I wouldn't add the ground strap. You might actually create a ground loop and degrade the performance of your system.

I've had my 7700 for about two months now, and it does the same thing -- takes about 25 seconds to power up and change the red light to blue. Seems perfectly normal to me.

No issues with humming. LOVE the sound -- so crisp and detailed, I easily hear distinctive raindrops falling around me when I'm in the main lobby of Halo: Reach, played in 6.1 Dolby PLIIx Game mode via HDMI.
