currently in speak. DS5 displays the text "RUN"
indicating that the BS5 button is now used to start
an automatic test of the microphones. When the
MC 4000 is running an automatic test of the
microphones, the led LS5 is lit, and the
microphones are sequentially put in request and
speak. DS6 displays the text "PREV" indicating
that the BS6 button is now used to switch on the
microphone preceding the microphone currently in
speak. It is only possible to use the previous button
when the MC 4000 is not running the automatic test
sequence.
DR5 displays the text "NEXT" indicating that the
BR5 button is now used to switch on the
microphone following the microphone currently in
speak. It is only possible to use the next button
when the MC 4000 is not running the automatic test
sequence.
The SET MODE button is used to leave the test
operation mode and return the MC 4000 to normal
operation mode.
Program Operation mode
This mode of operation is used to assign logical
numbers to the microphones in the system.
Giving the individual microphones numbers it is
necessary to make a distinction between the
physical microphone number and the logical
microphone number. The physical microphone
number is given automatically to each microphone
by the system depending on the connection of the
individual microphone in the system. The first
microphone connected to chain 1 on the master CU
has the physical number 1; the second microphone
connected to this chain has number 2, etc. The
microphones connected to chain 2 on the master
CU has the physical numbers 51,52 ... (Note that
this applies regardless of how many microphones
are connected on chain 1). The microphones
connected to slave CU number 1 chain 1 are
numbered 101,102 ... and slave CU number 1 chain
2 are numbered 151,152...
This numbering system applies to all slave CU's in
the system - the first microphone on slave number 9
chain 1 has number 901. In order to ease the remote
control of the microphone system it is possible for
the user to assign new numbers to the individual
microphones. These numbers are called logical
numbers and are not depending on the connection
of the microphones in the system. When the MC
4000 is operated in the normal operation mode the
logical numbers are used to control the system, thus
enhancing the operation of the microphones by
hiding the cabling of the system from the operator.
The connection between physical and logical
numbers is established in the programming mode
by the operator and preserved during power off.
The programming described here will normally
only have to be done once upon installation of a
permanent microphone system. If more than one
MC 4000 panel is used, it is possible for the two
MC 4000 panels to operate with independent
conversion tables (this is not recommended).
The keys 'P', 'R' and 'S' that are normally used to
switch microphones on, off, in request or pre-select
are not operational in this mode.
The different volumes (input, microphone and
headset) are displayed and controlled normally in
program operation mode.
DS1 displays the text "

PHY" indicating that the
column of microphone numbers in DS2-DS5 refer
to the physical microphone numbers and that
pressing the BS1 button will scroll the view of the
list down one position. DR1 displays the text
