Installation And Connection - Alto HPA6 Owner's Manual

Ok, you have got to this point and you are now in the position to operate your
HPA6 successfully. However, we advise you to read carefully the following section
to be the real master of your own mix. Not paying attention enough to the input
signal level, to the routing of the signal and the assignment of the signal will result
in unwanted distortion, a corrupted signal or no sound at all. So you should follow
this procedure for every single channel:
4.1 Mains Connection
Please ensure that the HPA6 is set to the correct supply voltage before plugging
the power cord into the wall outlet, use the same fuse as marked on the fuse
holder at the AC power connection socket. The mains connection of the HPA6 is
made by using the enclosed mains cord and a standard IEC receptacle. It meets
all of the international safety certification requirements.
4.2 Audio Connection
The HPA6 presents with balanced XLR and 1/4" TRS phones jack. It can be
interfaced by several ways to support a variety of applications without any
signal loss. The defective wiring may degrade the performance of HPA6, so
please use good quality screened audio cables only. Please follow the guide
below to interface HPA6 without experiencing any noise or signal loss.
