Input Connections; Output Connections - Ecler AMPACK2-70 Manual De Instrucciones

3.3. Input connections

The signal input use electronically balanced EUROBLOCK connectors (7) with input impedance greater
than 20kΩ and a nominal sensitivity of 0dBV(1V). The pin out is as follows:
Additionally, the AMPACK2-70 has an unbalanced stereo RCA input (6) for direct
connection of audio sources like CD players, DVD players, media players, etc.

3.4. Output connections

The outputs (11) are located on the front panel with Euroblock connectors.
The cables that connect the AMPACK's outputs with the loudspeakers must offer high
quality, with sufficient section and as short as possible. This is especially important when the
distance between amplifier and speakers are great; a section of at least 2.5mm
distances up to 10m; for greater distances, section should be greater than 4mm
in mono or stereo and 8Ω when using the bridge mode. For a correct operation of the AMPACK lower
impedances than the ones described previously should not be used.
Caution: In bridged mode only the terminal indicated on the unit should be used.
