Appendix D Microphone Phantom Power
Phantom Power on the JSM-MIC-DB or JSM-MIC-RJ cards may be enabled by selecting Cue @ Infinity in AEConfig.
However, the Cue @ Infinity function remains active, so when the fader is brought down to zero (infinity mark) the
channel will engage cue. If microphone muting is enabled for Monitor In, engaging cue will mute the control room
monitors.
To avoid this situation, we need to send the same command to the MIC IN card that enabling Cue @ Infinity does
without checking the box. This is accomplished using an ASM assembly language command in Command Builder.
Assembly language programming is an advanced function best performed by Logitek Support personnel. Please contact
Support and have them implement this feature for you.
For the JSM-MIC-RJ card:
cmd ae1 asm “02 09 86 a1 cs 00 04 86 02 00 mi”
For the JSM-MIC-DB card:
cmd ae1 asm “02 0A 86 a1 cs 00 05 86 02 00 00 mi”
where CS = Card Slot and MI = Mic ID
Card Slot is defined as follows:
Slot A = 01
Slot B = 02
Slot C = 03
Slot D = 04
Slot E = 05
Slot F = 06
Slot G = 07
Slot H = 08
Mic ID is defined as follows:
All Off = 00
Mic 1 = 01
Mic 2 = 02
Mic 3 = 04
Mic 4 = 08
Mic 5 = 10
Mic 6 = 20
Mic 7 = 40
Mic 8 = 80
All Mics = FF
Add hex numbers together to enable several microphones on the same card. (8 mics = FF)
This command is best placed in the init trigger, ensuring that the phantom power is turned on when
the unit boots up. (trigger init)
