LECTRO OICE
The Link, Id and Mask parameters (see following table) are used for linking parameters of Dx46 devices connected
via Ethernet. Use the < SELECT > buttons to navigate to the Link, Id and Mask parameters. Use the VALUE up/
down buttons to edit the corresponding value.

PARAMETER UNITS
This window allows selecting the unit used for temperature and the limiter threshold. Additionally the air temperature
can be entered.
The parameter Temp is used to calculate the speed of sound for converting delay times into distance. Use the <
SELECT > buttons to navigate to the Temp and Units parameters. Use the VALUE up/down buttons to choose be-
tween -4.0 °F to +140.0 °F or -20 °C to +60 °C. The Units parameter lets the user choose between Fahrenheit and
Celsius.
Use the < SELECT > buttons to navigate to the Limiter Threshold parameter. Use the VALUE up/down buttons to
choose dBu (DSP output) or Vpk (Amp output).
Sound travels at different speeds depending on the density of the surrounding air it is traveling through. Cold air is
denser than warm air thus, travels slower than it would if the air was warmer. Temperature can have a major influence
with greater distances, particularly with respect to widely separated speaker arrays surrounding the audience for
example. Temperatures might vary wildly between an indoor environment and an outdoor evening environment for
example.
V = 331m/s + (0.6m/s/C) * T
The speed of sound at room temperature is 346 meters per second. At freezing temperatures sound travels at 331
meters per second. V is the speed of sound and T is the temperature of the air. This formula finds the average speed
of sound for any given temperature (celcius). The speed of sound is also affected by other factors such as humidity
and air pressure.
M
ETERING
Users can set their VU metering preferences here.
Use the < SELECT > buttons to navigate to the VU Mode parameter. Use the VALUE up/down buttons to choose
between Normal Fast, Peak Hold and Slow Decay. Use the < SELECT > buttons to navigate to the VU Reference
parameter. Use the VALUE up/down buttons to choose between D/A Clip and Limiter Threshold.

Description
The link setting only works if more than one Dx46 device is connected to an ethernet. Devices that are Master
or Slave have always idential parameter settings. Select „Master", if this Dx46 should write the parameter set-
tings to one or more other Dx46 (Slave). Select „Slave", if the parameter settings of this Dx46 should be read
from another Dx46 (master). Select „off", if the parameter settings of this Dx46 should be independent from
other devices.
Each master Dx46 connected to the ethernet must have an unique network id. Enter the id of the Master Dx46
the parameters should be read from if this Dx46 is used as „Slave".
If the Link „Slave" is selected, choose the parameter groups that this Dx46 should read from the Master Dx46.
Following
groups are available:
• D: Parameters of the device
• A or B: Parameters of input A or B
• 1 to 6: Parameters of output 1 to 6
