3.3. Input connections
The signal input use electronically balanced EUROBLOCK connectors with input impedance
greater than 20k
Ω
and a nominal sensitivity of 0dBV(1V). The pin out is as follows:
There is an additional stereo, unbalanced, stereo RCA input to connect audio source as
CD’s, DVD’s, satellite receivers, etc…
3.4. Input options
The AMPACK admits the following operation modes, which can be selected easily using
the configuration jumpers. You have to use tweezers or another appropriate tool to move the
jumpers.
•
Stereo
•
Parallel: for mono applications. In this mode, the R input is inhibited, so that the signal present
on the L input (EUROBLOCK or RCA) will be the only valid signal. This signal will be amplified
and sent to both OUT L and OUT R outputs.
•
Bridge: for mono applications. In this mode, the R input is inhibited, so that the signal present
on the L input (EUROBLOCK or RCA) will be the only valid signal. In bridge mode the
AMPACK80 delivers 124W RMS and the AMPACK25 36W RMS. Please connect the output
cables as shown on the unit when using the bridge mode.
The AMPACK is configured for stereo mode by default.
3.5. Output connections
The outputs (15, 16) located at the rear panel have terminals which can be screwed on.
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.
Attention: in bridge mode only can be used the indicated terminals.
