The front panel controls on an individual m802 can be locked to prevent unintended changes to its settings.
Preamplifier settings can still be controlled from the RCU or via MIDI. To activate lockout mode, press and hold
the DATA knob for 5 seconds. When in Lockout Mode, the words “interface locked” will appear on the LCD dis-
play (see figure 6 below). To exit lockout mode, press and hold the DATA knob for 5 seconds. The m802 will
return to normal front panel control. Note that the m802 lockout mode can only be activated at the preamplifier
front panel or via MIDI. Lockout mode cannot be activated from the RCU.

When the m802 detects activity on its MIDI input port, it will switch to MIDI Control mode. In this mode the
m802 will emulate the AVID pre microphone preamplifier. In Pro Tools® the mic pre controls will control the
m802 as if it were a AVID pre. If there is no activity on the MIDI input port for a period of 16 seconds, the m802
will revert to its normal control mode. Pro tools sends a “heartbeat” message to all preamplifiers that are de-
clared in the pro tools setups > peripherals menu. The “heartbeat” signal happens every 8 seconds, which will
keep the m802 in MIDI mode perpetually. If using a generic MIDI controller, the m802 will switch to MIDI Control
mode whenever it sees a command on its MIDI input port and then switch back to normal control mode after
16 seconds of no MIDI activity. When in MIDI Control mode, the preamplifier can still be controlled at its front
panel or from the m802 RCU.
MIDI channel
For multiple m802 preamplifiers to exist on one MIDI buss, each preamplifier must be set to a
unique ID number. The ID setting represents the MIDI channel by which the preamplifier will be controlled. An
ID setting of 1 will cause the preamplifier to communicate on MIDI channel 0. An ID setting of 2 will cause the
preamplifier to communicate on MIDI channel 1 and so on. The maximum number of m802 preamplifiers that
can exist on a single MIDI buss is 8.
Lockout
If the m802 receives a MIDI lockout command, the front panel controls will be locked out and changes
