THE POWER-SWITCH
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 flashes 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.
DHA V590 will always start with the last settings of the input-, output- and
resampling configuration.
THE ANALOGUE SIGNAL INPUTS
THE BALANCED SIGNAL INPUTS
are situated on the rear panel of the unit and are labelled as "XLR IN L" and
"XLR IN R". 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 8/9 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 L 1/2” and "RCA IN R 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 DIGITAL SIGNAL INPUTS
Four digital inputs are found on the unit's rear
panel. They are denoted according to their
electrical properties: balanced, coaxial
(unbalanced), optical and USB.
You will not find terms like AES, S/P-DIF,
professional or consumer here, since it doesn't
matter at all which signal type is applied to a
dedicated input.
