Installation; Inputs - Ecler SAM612T Notice D'utilisation

3. INSTALLATION

Ecler SAM612T has been specially designed to be installed in a standard 19" rack, taking up 1U. It
has been designed to be operated by non-technical users. This is the reason why its tone controls are
adjustable only with a screwdriver. On the opposite, input and output level controls use classic and easily
accessible rotary knobs.
Due to its low power consumption and heat sink, SAM612T doesn't need any fan cooling. However,
avoid installing it in dusty environments and/or in a location with extreme temperature and moisture.
The mixer should be kept apart from noise and interference sources (dimmers, motors, etc...) as
well as from power cables.
Ecler SAM612T operates from 90V to 264V CA, 47 to 63Hz. Its oversized power supply is
compatible with any mains voltage worldwide.
In order to protect the mixer from eventual overloads, SAM612T is protected by a timered power
fuse (21) of 0.5A. If it gets blown up, you must replace it with an identical one. If it gets blown up, you
must replace it with an identical one. NEVER REPLACE THE FUSE WITH ANOTHER ONE WITH A
HIGHER VALUE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

4. INPUTS

Each SAM612T channel has two input types (MIC/mono, LINE/stereo), selectable using a switch on
the back panel:
•
Microphone signal (11): the 6 mixing channels are provided with screw terminal strips and accept a
nominal input level from -50dBV (3.16mV) to –20dBV (0.1mV), ± 15dB gain to be adjusted on the
back panel (14).
There is also another jack input for microphone on the front panel (1), connected in parallel with the
one for the same channel on the back panel.
Wiring diagram for microphones:
Microphones must be low impedance (200 to 600Ω) and monophonic.
SAM612T has a Phantom power supply for condenser microphones, individually switchable by
internal jumpers (for each microphone). Cf diagram. The Phantom power supply is activated by default
(factory setting).
The Talkover function is activated when a signal presence is detected on Input 1. Then it
attenuates the other unit inputs. It can be activated/deactivated by the "TK" switch (2), located on the
front panel.
