RCF ZM 2124 240W 6 Zones Powered Master Unit - Manual (Page 18)

18
ENGLISH
ZM 2100 only: when using one or more external amplifiers per each zone, link every
external amplifier input to its respective zone loudspeaker output, which is here used as a
0 dB audio output (see the next ‘ZM 2100 - 0 dB zone commutation’ manual section).
66 DC 24 V (removable connector)
Input for secondary 24 V dc power supply (i.e. batteries) that will maintain the operation
of unit if the AC power (from mains) is temporarily unavailable.
Double check the correct polarity + / – when connecting.
ZM 2100 allows to use an external amplifier (or more) per each of the 6 zones.
All ZM 2100 internal relays are (in this case) used to switch 0 dB audio signals (instead of
100 V lines).
ZM 2100 needs to be set to the dual amplifier mode through its respective dip-switch
[28].
CONNECTIONS
Link the PRE OUT 1 34 directly to AMP IN 1 63 and PRE OUT 2 34 directly to AMP IN 2
64 .
Link the A ÷ F 65 outputs to the external amplifier inputs.
NOTES:
- Custom cables need to be made.
- All ZM 2100 contacts labelled ‘100 V’ are here used for the signal.
- All ZM 2100 contacts labelled ‘0’ are here used for the ground.

NOTES
65 A to F (removable connector)
Six 100 V loudspeaker outputs affected by zone selection.
In the ‘power sharing’ configuration, the total loudspeaker power (the sum of all the 6
zones) cannot exceed 240 W.
Each loudspeaker shall have a 100 V input.
