3.4. Input connections
MPA4-150R
MPA6-150R
Signal inputs (23) are provided on Euroblock type balanced connectors (electronically balanced),
with an input impedance greater than 20kΩ and a rated sensitivity of 0dBV (1V).
The "STACK" are in parallel with the inputs and are used to supply the same "IN 1, IN 2" input
signal to other amplifiers or sound systems.
Some of the connection options and the corresponding switch settings are described later in
paragraph 3.5.
Depending on the option chosen, the front panel "SP" signal indicators will light up only for active
channels.
