3.3. Input connections
The signal input use electronically balanced EUROBLOCK connectors (7) with input impedance greater
than 20k
Ω 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
2
is recommended for
distances up to 10m; for greater distances, section should be greater than 4mm
2
.
Remember that the minimum operation impedance is 4
Ω when using the amplifier
in mono or stereo and 8
Ω 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.
