Model 5204
Dual Line Input to Dante Interface
lights red in color when a signal levels is
–5 dBFS or greater, indicating that a poten-
tially “clipped” (distorted due to excessive
level) signal is present.
Input A
The signal connected to the tip (left chan-
nel) connection of line input A’s 3.5 mm
jack is associated with Dante transmitter
(output) channel 1. The ring (right channel)
connection of the 3.5 mm jack is associated
with Dante transmitter channel 2. The push-
in/push-out rotary control adjusts the input
level of both channels of line input A. In its
fully counterclockwise position the input
signal are essentially off (muted). Adjust
the control such that normal input signals
will cause the five green LEDs to light.
Peak signals can cause the yellow LED
to light on occasion. But the yellow LED
should never be continuously lit. The red
LED should never light, except possibly in
the case of an extreme peak. The red LED
lighting on a regular basis indicates that
the signal level is at risk of reaching digital
0 (0 dBFS) which is destructive to audio
quality.
Input B
The signal connected to line input B’s
channel 1 3-pin female XLR connector is
associated with Dante transmitter (output)
channel 1. The signal connected to line
input B’s channel 2 XLR connector is asso-
ciated with Dante transmitter (output) chan-
nel 2. The push-in/push-out rotary control
adjusts the input level of both channels of
line input B. In its fully counterclockwise
position the input signals are essentially off
(muted). Adjust the control such that normal
input signals will cause the five green LEDs
to light. Peak signals can cause the yellow
LED to light on occasion. But the yellow
LED should never be continuously lit. The
red LED should never light, except possibly
in the case of an extreme peak. The red
LED lighting on a regular basis indicates that
the signal level is at risk of reaching digital
0 (0 dBFS) which is destructive to audio
quality.
Line Inputs A & B Combine
It’s important to highlight that the Model
5204’s two 2-channel line inputs (A and B)
combine in the analog domain. In effect
the Model 5204 is a dual-input 2-channel
(stereo) mixer and Dante converter. A sig-
nal present on channel 1 (left) of line input
A and a signal present on channel 1 of line
input B will combine (mix together or sum)
after (“post”) the two level controls. This
combined signal is routed to the analog-
to-digital converter circuitry and on to the
Dante transmitter (output) for channel 1.
A signal present on channel 2 (right) of line
input A and a signal present on channel 2
of line input B will combine (mix together
or sum) after (“post”) the two level controls.
This combined signal is routed to the ana-
log-to-digital converter circuitry and on to
the Dante transmitter (output) for channel
2. But note that no monaural version of the
input signals is created.
USB Dedicated Charging Port
There are no special instructions when using
the dedicated charging port. Simply connect
the desired device and the function will typi-
cally automatically start. The only limitations
will be with the port’s 5 volt, 1 ampere (5
watt) maximum power supply capability.
A connected device that requires more
energy for operation may not enumerate
(handshake or negotiate) successfully. No
damage will occur in this case.
