MODEL 348
INTERCOM STATION
Dante Monitor Outputs – Dim
Choices are 0 dB, 6 dB, 12 dB, and 18 dB.
When a talk or IFB function is active the Mod-
el 348 will invoke a dim (attenuation) function.
This is designed to help achieve maximum
intelligibility and minimize the chance of
acoustic feedback when loudspeakers are
associated with either or both Dante monitor
outputs Monitor A or Monitor B. A
dim setting
of 0 dB means that the signal level on the
Dante monitor outputs will remain unchanged.
(The signal will be attenuated by 0 dB which
is no attenuation!)
System – Level Control Position Display
Choices are Off and On.
For user assistance the orange LEDs con-
tained within the eight pushbutton switches
can be utilized in a “bar graph” format to give
a general indication of the settings of the ten
rotary encoders. If enabled, whenever the set-
ting of a rotary encoder is changed the LEDs
eight buttons will momentarily light. In most
cases it would be advantageous to enable
this function.
System – Signal Present Display
Choices are Off and On.
The top surface of the ten rotary encoders
can light as an indication of the level of the
audio associated with a specific encoder and
related function. This is accomplished by the
incorporation of red, green, and blue LEDs
located within each encoder. The knob will
light green when signal levels are in the
normal range, yellow when the signal level is
greater than normal, and red when the sig-
nal level is at risk of degrading audio perfor-
mance. Note that even if the Signal Present
Display function is disabled (Off) the rotary
encoders will still display their normal and
muted state using LED illumination.
System – LED Intensity
Choices are Low and High.
The eight pushbutton switches, ten rotary en-
coders, and mic source selection function have
LED indicators associated with them. The
LED intensity configuration choice allows the
overall intensity of these LEDs to be selected.
Typically, deciding which choice, low or high, is
optimal will depend on the amount of ambient
light present where the Model 348 is located.
System – Headset and Monitor Outputs
Follow Mic Source
Choices are Off and On.
This function allows the muted/unmuted state
of the headset’s headphone outputs, the Dante
monitor outputs (when configured for post-
fader), and the speaker output to automatically
be determined by the user’s choice of which
microphone is active. This is a sophisticated
function that can prove useful for users who
are frequently switching between the headset
microphone and the gooseneck microphone.
When the function is enabled, whenever the
microphone source selection changes from
gooseneck to headset the Dante monitor
output channels (only when configured for
post-fader) and the speaker will mute. And
whenever the microphone source selection
changes from headset to gooseneck the head-
set’s headphone outputs will mute. This helps
to ensure that unwanted audio isn’t present as
a specific microphone source is selected.
System – Hot Mic
Choices are Off and On.
A Dante transmitter (output) channel is avail-
able which provides a hot mic (always active)
function. This can be very useful but has the
potential for abuse. This configuration choice
ensures that a hot mic signal is only available
when an application warrants it.
