OPERATION
Unpack the DNS 2 carefully. Save the carton and all packing materials since you
may need them in the future. In addition to the DNS 2, the box should contain:
■
12V DC power supply
■
start-up and safety instructions sheet
■
warranty registration card
To maintain reliability and prolong operating life, observe the following
environmental considerations:
■
the temperature should be maintained between 5º and 30º Celsius
■
relative humidity should be in the range 30% to 80% non-condensing
■
strong magnetic elds should not exist nearby.
Power sources
Power is supplied by an external DC source of 8–17.5V with a lm industry 4-pin
XLR. A 12V PSU is included with the unit and this will work on any mains supply in
the range 85V to 250V, 50/60Hz AC. Connect its output to the DNS 2 power input
and then plug it into the mains supply.
Press the power on/off button to switch power on and off:
■
press the button briey to switch the power ON
■
hold the button for a couple of seconds to switch the power OFF
Controls
Each channel has its own process controls and indicators. These comprise two
illuminated push buttons, a rotary encoder with an integrated push switch, and a
small dot-matrix display. These are used for both setup and process control.
Connections
The DNS 2 offers analog and digital audio connections. It can pass its signal to
both outputs irrespective of the input used.
Select the active audio input using the two-position toggle switch on the side of the
unit. When the analog inputs are in use, a three-position switch for each channel
selects between line, microphone and microphone with +48V phantom powering.
High pass lter
An 80Hz, -18dB/oct high pass lter is available across all inputs. To toggle this for
either channel, press SETUP followed by the appropriate LEARN button. An icon
on each channel’s screen will show whether the lter is active or not.
Analog input
Set the input selector switch to ANALOG IN (switch to left).
