4.15. Program input (PROGRAM IN)
Unbalanced analog input with an
RJ45 connector and a sensitivity
of 0 dBu
(775 mV).
It is especially suitable for
receiving a local program signal
(e.g. a CD player, tuner…).
Use Cat 5 STP cable for its
connection.
4.16. MAIN IN
Unbalanced analog input with an RJ45 connector and a
sensitivity of 0 dBu
(775 mV).
It is used, together with the PRE OUT output, to insert a unit
(equaliser, anti-larsen...) between the preamp and the power
unit of the amplifier (see Figure 10).
To enable this input, move the LINK switch of the MAIN IN input
to ON.
Use Cat 5 STP cable for its connection and refer to Figure 8.
4.17.
PRE OUT
Unbalanced analog output with an RJ45 connector and a
sensitivity of 0 dBu
(775 mV).
The audio signal is always present in this output.
It is used, together with the MAIN IN input, to insert a unit
(equaliser, anti-larsen…) between the preamp and the power
unit of the amplifier (see Figure 10), or to send a signal to
other power units (see Figure 11).
It has an output priority contact, which is activated according
to the configuration of the power unit (see section 6.2.2).
Use Cat 5 STP cable for its connection and refer to Figure 9.
