different zones but the total power must not exceed 240W.
16. 0/8Ω/70V/100V Speaker Output
This terminal (21) provides the output signal of the internal power amp of the internal power amp of the UCA 8240.
Simultaneous utilization of the different outputs (8Ω/70V/100V) is not possible. If the 8 Ohm output is being used,
no speakers must be connected to the zone outputs 1 – 6 (57).

17. Remote Power

The UCA 8240 can be remotely switched on by feeding 24V DC to the terminal (22). To utilize this function the
