Activating The Microphone Phantom Power; Program Input Configuration In A Multichannel System (Master-Slave) - Altair EF-200 Owner's Manual

audio systems (factory set-up). This configuration can be modified to make the PA OUTPUT always
enabled with the microphone sending of the HEADSET connection with an internal DIP-SWITCH
(DSW1, position 2, PROGRAM OUT WITHOUT RELAY, placed at the front left corner of the main PCB
of the unit).
With the position 2 of the DIP-SWITCH in OFF (downwards, looking at the unit from the front
panel) the PA OUTPUT will be enabled only when the PA-MIC switch is pressed (factory set-up),
and with the position 2 of the DIP-SWITCH in ON (upwards, looking at the unit from the front panel)
the PA OUTPUT will be enabled always.
NOTE: The multipurpose relay associated with the PA-MIC switch doesn't suffer variation in its
operation changing this configuration.
PA OUTPUT ENABLED
BY MEANS OF
PA-MIC SWITCH.

ACTIVATING THE MICROPHONE PHANTOM POWER

The microphone PHANTOM power can be activated or disabled with an internal DIP-SWITCH
(DSW1, position 3, MIC PHANTOM, placed at the front left corner of the main PCB of the unit).
With the position 3 of the DIP-SWITCH in OFF (downwards, looking at the unit from the front
panel) the PHANTOM power is disabled, and with the position 3 of the DIP-SWITCH in ON
(upwards, looking at the unit from the front panel) PHANTOM power is enabled.
If an electret microphone is used, the PHANTOM power must be enabled and if a dynamic
microphone is used, the PHANTOM power must be disabled. The microphone PHANTOM power is
9 VDC.
PHANTOM POWER
DISABLED.

PROGRAM INPUT CONFIGURATION IN A MULTICHANNEL SYSTEM (MASTER-SLAVE)

In a multichannel system (MASTER-SLAVE) the program input corresponding to the unit
configured like MASTER will be the only one to work, but it will be sent to all the lines with the level
control and the program sending to lines A/B switches (factory set-up). Nevertheless, the program
input can be configured to make the program input working in units configured as SLAVES in
multichannel systems, with a internal DIP-SWITCH (DSW1, position 4, PROGRAM INPUT IN SLAVE
MODE, placed at the front left corner of the main PCB of the unit).
With the position 4 of the DIP-SWITCH in OFF (downwards, looking at the unit from the front
panel) in a multichannel system the program input will only work in a unit configured like MASTER
(factory set-up), and with the position 4 of the DIP-SWITCH in ON (upwards, looking at the unit from
the front panel) in a multichannel system the program input will works in units configured as
MASTER or SLAVES.
