switched on.
3. Before powering up the power ampli er, make
sure that the mains voltage corresponds to the
voltage value set on the selector (ref. 24, Fig. 1 -
pag. 42). If not, ask your RCF S.p.A. dealer
to con gure the unit for the correct
voltage.
4. The metallic parts of the unit are earthed by
means of the power cable. If the current outlet
used for supplying the unit does not provide an
earth connection, contact a quali ed electrician
to earth the unit using the terminal (13) (Fig. 1-

- 1 unbalanced RCA input
- 1 balanced input on terminal strip
- 1 RCA output in parallel with the unbalanced
input
- Possibility to give the balanced input priority over
the unbalanced input
- RCA input sensitivity selectable between 0 dB and
-20 dB
- Outputs for speakers with constant impedance
(4 Ohm) and constant voltage (25-50-70-100 V)
- Stand-by mode which makes it possible to switch
the unit on by remote control (excludable)
- Auxiliary output for overload indication
