Ecler SAM412T - Manual (Page 6)

• Line signal (14): stereo RCA inputs, compatible with CD, DAT, MP3, DVD-Audio players, etc..
All these inputs accept 0dBV (1V) line level signals.
Turntables CAN NOT be directly connected to this unit, because SAM412T has no RIAA preamp
equipped input.
In addition, MIX IN (15) input directly access to the main mixing bus. It is especially useful to
connect a second SAM412T or another mixer in order to increase the number of mixing channels and
inputs.
5. OUTPUTS
The SAM412T has two main outputs, with their type of connector as only difference: electronically
balanced screw terminal strips (17, 18) and unbalanced RCA connectors (20).
Connection is made according to the following diagram:
In order to use a balanced output, you need to short pin 2 and pin 3, as indicated in the previous
diagram. Otherwise, the output signal won't have the right level and quality.
The mixer's main output level (OUTPUT VOL (7)) must be set in order to avoid your system power
amp clipping indicators (CLIP) to be permanently lit. Only the most powerful lower frequencies must light
them.
Other connections on the back panel:
• REC output (16), 0dBV nominal, 10kΩ.
• L+R switch (19): convert output signals in a mono signal.
• MUTE remote control input (21): external contact closure input. Allows connection of fire detection
systems or any other safety device that have to mute the mixer by activating this control signal. The
operating mode is internally selectable by jumpers as "NO / NC" (normally open / normally closed).
