4.1. Phantom power supply

The mixer features a general activation switch for the phantom power supply (20) necessary for
condenser microphones. The switch is located on the devices rear panel. Additionally, a set of internal
jumpers can be used to individually disable the phantom supply on each MIC input. The SAM614T is
delivered with these internal jumpers set to PHANTOM ON. In order to disable one channel's phantom
supply, please refer to the configuration diagram.

4.2. Talkover

The purpose of this circuit is to automatically attenuate the musical signal. The talkover function
affects only the output bus A, that is OUT A and REC A.
In the SAM614T, this mechanism comes into action whenever there is signal present on the MIC
input of channel 1, consequently attenuating all other signals assigned to the output BUS A. It has an
efficient attenuation level of -30dB that can be internally switched to -20 or -70dB and it is activated
starting from the first voice sound. The time in which the musical signal recovers its original level is 2
seconds. This time can be internally modified to 1 or 3 seconds. Please refer to the configuration
diagram.
It is also possible to modify the unit so that another microphone input or even a line input
activates the talkover function. To modify the talkover activation channel please refer to the configuration
diagram.

5. OUTPUTS

5.1. OUT A / B

The SAM614T features two main outputs OUT A (26-27) and OUT B (28-29). They are identically
laid out balanced outputs with XLR-3 sockets.
Following connection scheme should be used:
Hot or direct signal
Cold or inverted signal
Ground
The balanced circuitry simulates the behaviour of a transformer. If you wanted to use one of the
outputs in non-balanced mode, you need to connect to ground the output terminal not being used.
Otherwise, the output signal would not have the necessary level nor quality.
A / B Output assign pushbuttons (2-4): One of the main advantages of the SAM614T mixer is that
the input signals can be directed to any of the two outputs or to both simultaneously. This feature is
particularly useful when you need to send music or spoken messages to specific zones. The A / B
pushbuttons and their associated LED indicators (7-8) let you redirect each input to the desired output.
ATTENTION: Care should be taken when adjusting the mixer's general output level OUT VOL
(12). The "clip" indicators of the connected power amplifier should never stay permanently lit. It may
however sporadically light up to the rhythm of the lowest frequencies of the music.
The two outputs each have a mono/stereo switch (10) summing the left and right channel signals.
Changing input sensibility from 0dBV to +6dBV: Although both main outputs are factory adjusted
for a nominal level of 0dBV, it is possible to individually raise the level to +6dBV by means of internal
connections. To modify the nominal output levels please refer to the configuration diagram.
