CHIME LEVEL (a trimmer adjustable by using a small screwdriver).
[
Amplifier output (max. 80 W) to loudspeakers, available as:
•
100 / 70 V constant voltage line
•
Low impedance (min. 4 Ω).
Use 1 output only (read the section 'Loudspeaker connection').

Mains connector with fuse
Before connecting the power supply cable, verify that the apparatus voltage (230 or 115 V ac)
corresponds to the available mains supply.
Note: the fuse type is marked on the rear panel (below the mains connector).
OPERATION
'VOX' is an internal circuit that automatically opens the channel 1 and takes priority (if enabled
through the dip-switch 3, see 21) when a signal is detected on its input.
'MIX' MODE
The priority function is disabled. All signals (channel 1-2, if open, and the selected AUX INPUT) are
always present, mixed together and sent to the internal amplifier.
The music volume (coming from a CD / MP3 player, a tuner, etc.) depends on the aux input volume
control on the front panel (see 3) and also the respective GAIN control setting (see 16 and 18) on
the rear panel.
'GRADUATED PRIORITY' MODE
Audio inputs are managed according to graduated priority levels:
1.
(highest) channel 1
2.
channel 2
3.
the selected AUX IN.
If a priority command is present (or VOX), only the signal of the channel with the highest priority level
is sent to the internal amplifier (and PRE OUT), while the other inputs (with lower priority level) are
momentary muted (until the priority command is removed).
RCF BM 3001 PAGING MICROPHONE (NOT INCLUDED)
The channel 2 has an RJ 45 port, to which a BM 3001 paging microphone can be connected
(note: it is necessary to set the dip-switches 1 and 2 to the 'LINE with PHANTOM' mode; see 11).
The BM 3001 paging microphone shall be set to 'LOCAL'.
