Phantom Power Supply; Talkover; Outputs; Out A / B - Ecler SAM614 Bedienungsanleitung

-Connection to other mixers: When operating as a slave device, the SAM614 can be
connected to another mixer using the REC outputs (24-25). On the other hand, the SAM614 can
receive another mixer's output signals through any of its LINE inputs (master operation).

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 SAM614 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 SAM614, 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. The
attenuation amount, or efficiency, is 30dB and starts at the first voice hit. 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 SAM614 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:
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.
