First let me start out with the A51 that I purchased was used, and so this mabey the reasons for my concerns. After opening the box for inspection the first thing I noticed was the left and right heatsinks are not flush with each other. What I mean is that the two individual aluminum heat sinks that run the entire left and right sides are not flush along the top. So I guess my question is, is this normal or could these heatsinks have actually shifted during shipping(I Dought) this or mabey a repair?
My other question is because of this I did not want to set this all up until I plugged it in and just verifiyed if powered up. The Parasound emblem lights up red and the power button lights up blue but none of the 5 channel lights are lighting up. Could this just be because i do not have any speakers hooked up or interconnects yet?
One last thing I would like to know is if the power button is suppose to click when trying to turn on the amp. when I press the power button it has a very soft feeling to it when pressing almost as though its not working correctly, as nothing happens. This could also because i am comming from the Rotel RMB 1095.
I would appreciate any suggestions or help as this is my first parasound amp, and if I am able to post pics of the heat sinks I will do so in another post.
I have two Halo amps and the heatsinks on both are level. Why they aren't on your's I don't know; as you say, it will probably be down to transit damage or repair work.
The power button on the amp doesn't click as such and is just a touch and release kind of thing.
Unless the 'power-up mode' switch on the back of the amp is in the 'manual' position, then the amp (when only connected to mains power) will not fully power up when you press the power button on the front - the five channel LEDs will not light up.
The power-up mode switch on the back has three positions - one for manual (using the power switch on the front), one for signal input sensing (detects an input signal and powers up the amp) and the third one is for when you use a 12 volt input to turn on the amp (from the audio processor, for example).
With the power-up mode switch on the back in manual, after pressing the power switch on the front, both the power switch and all five channel LEDs should be blue after a second or so.
