THE POWER-SWITCH
THE ANALOGUE SIGNAL INPUTS
THE BALANCED SIGNAL INPUTS
are situated on the rear panel of the unit and are labelled as "XLR IN Left"
and "XLR IN Right". They are fitted with gold plated XLR sockets from
Neutrik.
Please note:
Unbalanced signals can be injected as well by means of an adaptor.
See page 8 to learn more.
THE UNBALANCED SIGNAL INPUTS
For the use with unbalanced signals, gold plated RCA sockets are provided.
They are labelled as "RCA IN Left 1/2" and "RCA IN Right 1/2".
The input impedance on all analogue inputs is 10 kohms.
Maximum input level should not exceed +21 dBu.
It is reduced to +3 dBu when PRE-GAIN +18 dB is engaged.
The unit is put into operation by means of the power switch.
The power-on procedure takes about 5 seconds.
During this time the "PROTECT" LED lights red until all internal parameter
are checked and found OK.
Any breakdown will cause the "PROTECT" LED to come up and the
outputs are muted.
HPA V550 will always start with the last settings of the
input- and output configuration.
