adjusts the level of input 1 and potentiom-
eter Ch 2 adjusts the level of input 2.
Headphone Minimum Level
Switch SW3 is used to configure the
headphone output’s minimum level. In
the –40 dB setting the minimum head-
phone output level is approximately 40 dB
below maximum; the headphone output
channels will never fully mute. This en-
sures that audio signals, when present
on the inputs, will always be present on
the headphone output channel. In most
on-air broadcast applications this is the
appropriate setting, ensuring that some
level of signal is always present.
When full mute is selected moving either
potentiometer to its fully counterclock-
wise position will cause its associated
headphone channel (or channels) to fully
mute. If a potentiometer is set to serve as
a balance control, moving Ch 2 it to either
its fully counterclockwise or fully clockwise
position will cause the associated head-
phone channel to fully mute. Selecting the
full mute mode may be appropriate for
applications where minimizing the chance
of audio “leakage” is important. This could
occur when the connected headphones
or headset are at times placed on a desk
or tabletop, leaving audio emanating from
them to travel in “free space” to an “open”
microphone.
Operation
At this point everything should be ready
and Model 362 operation can commence.
An Ethernet connection with Power-over-
Ethernet (PoE) capability should have
been made. Alternately, a midspan power
injector, in “series” with the Ethernet con-
nection, should have been put into place.
A pair of headphones, a headset, an
earbud, or an earpiece should have been
connected.
The Model 362’s Dante configuration set-
tings should have been selected using the
Dante Controller software application. In
this way the unit’s two audio input chan-
nels (Dante receiver channels) should
have been routed from transmitter chan-
nels on associated equipment. The Model
362’s configuration switches should have
been set to meet the needs of the specific
application.
Initial Operation
The Model 362 will start to function as
soon as a Power-over-Ethernet (PoE)
power source is connected. However, it
may take 20 to 30 seconds for full opera-
tion to commence. Upon initial power
up the three status LEDs, located on the
bottom panel below the RJ45 jack, will
begin to light as network and Dante con-
nections are established. The green power
LED on the top panel will light in a special
sequence to display the major and minor
version numbers of the application firm-
ware (embedded software). Once that has
completed the power LED will light green.
After the power-up sequence has com-
pleted and the Dante connection has been
established full operation will begin.
