Installation; Inputs - Ecler SAM614T Manual De Instrucciones

3. INSTALLATION

This unit has been specially designed to be placed in a standard 19" rack, taking up 1 height unit.
The SAM614T is very well suited to be operated by people with a low technical knowledge. This is why
its input sensitivity and tone controls are not easily accessible. Both adjustments should be performed
from the front panel with a small screwdriver
Two considerations must be taken into account when you look for the right location where to put
your SAM614T: first, maximum user comfort and second, easy access to the back panel in order to plug
several different devices to and from the mixer.
Your SAM614T has a very low power consumption, so it does not need any fan cooling, but you
should avoid exposing the unit to very extreme temperatures and the atmosphere of the room where it is
located should be as dry and dust-free as possible.
Also, you should place the SAM614T away from noise sources (dimmers, motors, etc...), as well
as from the power cables.
The SAM614T operates under voltages between 90 and 264 V at 47 to 63 Hz. This device
features an over dimensioned power supply that adapts to the mains voltage in any country of the world
with no need to make any adjustments.
In order to protect the mixer from eventual overloads, the SAM614T is protected by a timered
power fuse (32) of 0.5A. 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

The SAM614T Mixer accepts two different input signal types: MIC and stereo LINE
- Microphones: Channels 1 and 2 feature microphone inputs. Channels 3 and 4 also include
microphone inputs but may additionally be switched to LINE. XLR-3 connectors (21) are used on all
microphone inputs, which are prepared to accept a nominal input level of -45dBV (5.6 mV). These
microphone inputs admit balanced operation. For that, it respects following connection scheme:
Hot or direct signal
Cold or inverted signal
Ground
Microphones should have a low impedance (200 to 600Ω) and be monophonic. For non-balanced
operation, Pin 3 must be shorted to ground.
- Stereo LINE inputs: These are placed on channels 5 and 6 as well as on channels 3 and 4,
which have an input switch and can be used alternatively as microphone inputs. Compact disc players,
tape recorders, videos... should be connected to any stereo LINE input, which feature RCA (23)
connectors. All these inputs accept line level signals ranging from -25 to +15dBV (56.2mV to 5.62V).
-Tuners and auxiliary devices: Any auxiliary device capable of delivering between 56.2mV and
5.62V should be connected to a LINE input (23)
- Turntables CAN NOT BE CONNECTED directly to the SAM614T, as none of the inputs has a
built-in RIAA preamplifier.
- SAM614T can be linked to another mixer by connecting one of its REC outputs (24-25) to a
LINE input on the other mixer that will be the main one.
