channel levels can result in much happier,
and more productive, users.
One of the headphone output modes uses
the control in the center of the unit as a
balance function. In this case the detent
position will send approximately equal
levels to both the left and right headphone
output channels. This is as one would
expect from a “stereo” balance control
such as provided in consumer electronic
equipment.
When the headphone minimum level con-
figuration is set to –40 dB, turning a level
control to its fully counterclockwise posi-
tion will cause the level of its associated
headphone output channel(s) to 40 dB
below maximum. This ensures that users
will never be fully “isolated” from poten-
tially important cue signals. In addition,
when a control is set to provide a balance
function, turning it to either its fully clock-
wise or fully counterclockwise position will
cause the level on the applicable head-
phone output channel to be 40 dB below
its maximum.
If the headphone minimum level configu-
ration is set for full mute, turning a level
control to its fully counterclockwise posi-
tion will cause the level of the associated
channel(s) to fully mute. In addition, when
a control is configured to provide a bal-
ance function, rotating it to either its fully
clockwise or fully counterclockwise posi-
tion will cause the level of the applicable
channel to fully mute.
The overall level of the headphone output
can be configured as desired for specific
applications. The default setting, low, is
designed so that users will typically set
the rotary controls at approximately 50%
of rotation. The high setting would be
applicable in cases where an extreme
headphone output level is required or the
source material that is provided on the
Dante receiver (input) channels is lower
than typical.
USB Interface
A USB type A connector and associated
status LED is located on the back panel of
the Model 214. This data interface is used
only for updating the unit’s operating firm-
ware (embedded software). No audio data
of any kind will pass through it. For details
please refer to the Technical Notes section
of this guide.
Technical Notes
IP Address Assignment
By default the Model 214’s Ethernet inter-
face will attempt to obtain an IP address
and associated settings using DHCP
(Dynamic Host Configuration Protocol).
If a DHCP server is not detected an IP
address will be assigned using the link-
local protocol. This protocol is known in
the Microsoft® world as Automatic Private
IP Addressing (APIPA). It is also some-
times referred to as auto-IP (PIPPA). Link-
local will assign an IP address in the IPv4
range of 169.254.0.1 to 169.254.255.254.
In this way multiple Dante-enabled devices
can be connected together and auto-
matically function, whether or not a DHCP
server is active on the LAN. Even two
Dante-enabled devices that are directly
interconnected using an RJ45 patch cord
will correctly acquire IP addresses and be
able to communicate and transport audio.
Using the Dante Controller software ap-
plication the Model 214’s IP address and
related network parameters can be set
for a fixed (“static”) configuration. While
