ERROR#043
This error occurs as the result of an 
AMLMN command. It happens when the 
command attempts to set a "last mic on" number that does not belong to the 
specified automixer while "last mic on" mode is set to manual. 
ERROR#044
This error occurs as the result of an 
AMCHAIR command. It happens when the 
command tries to enable chairman mode, but the chairman microphone is set to a 
microphone that does not belong to the specified automixer. 
ERROR#045
This error occurs as the result of an 
AMCHAIR command. It happens when the 
command tries to set the chairman microphone to a microphone that does not 
belong to the specified automixer while chairman mode is enabled. 
ERROR#060
This error occurs when the user has attempted to utilize more variable DSP 
resources than are available. This may occur if too many matrix crosspoints are 
unmuted or too many parametric EQ filters are enabled. The 
DSPLOAD command 
can query the current percentage utilization of DSP resources. 
ERROR#070
This error occurs as a result of a macro or preset execution command (
PRESETX, 
PRESETQ, MACROX, MACROQ). It indicates that the macro or preset requested was 
empty. 
ERROR#071
This error occurs as a result of a 
PRESETW or PRESETK command. In the case of 
PRESETW it indicates that an attempt was made to write to a factory preset, which 
is not allowed. In the case of 
PRESETK, it indicates that an attempt was made to 
delete a factory preset, which is not allowed. 
ERROR#072
This error occurs as a result of a 
PRESETQ command. It indicates that one or more 
commands in the preset had errors during execution. 
ERROR#073
This error occurs as a result of a 
MACROA command when there are already too 
many commands in the macro. The limit is 256 commands per macro. 
ERROR#074
This error occurs in response to a 
MACROA or a logic pin (LIA, LIH, etc.) command. 
If the command written to the macro or logic pin is illegal, then this error occurs. 
ERROR#075
This error occurs when a command attempts to write non-volatile memory, but non-
volatile memory is password protected via 
NVLOCK. 
ERROR#076
This error occurs when attempting to add a macro command (either during an 
upload or while writing a single macro) and the Vortex runs out of room in non-
volatile memory. As a result, the entire macro is discarded. If this occurs during an 
upload, all previous macros (before the one that caused the error) are written 
successfully. 
ERROR#077
This error occurs when attempting to add a command to a macro, but the Vortex is 
not in the process of writing a macro. This may happen if you forget to do a 
MACROS or UMACROS command, or if you had an ERROR#076 and continued trying 
to add commands. 
ERROR#090
This error indicates an EF Bus hardware handshaking error. This could happen if 
bussed units are not powered on simultaneously. Powering the units up 
simultaneously should remove the error. 
ERROR#091
This error indicates an EF Bus software handshaking error. This could happen if 
bussed units are not powered on simultaneously. Powering the units up 
simultaneously should remove the error.
