10. The RCA output marked as PRE OUT is intended for using
the preamplifier for controlling external power amplifiers
after disconnecting speaker wires and connecting them to
the amplifiers applied.

11. The RCA input designated as PA IN is intended for using only
end power amplifiers in the amplifier. The source selection
switch should be set to the PRE IN position.

VI. Amplifier warm-up time
During the production process, the amplifier undergoes
the preliminary break-in process after which the repe-
ated parameter inspection is carried out.

The complete break-in process takes place at the end user, after
about 1-2 weeks of use. If we move the amplifier to the another
user, the break-in process will be significantly shorter: in general,
0.5-1 hour will be enough.

and speakers against damage
In order to protect the amplifier and speakers, mainly
tweeters, the amplifier is equipped with 2 types of safe-
guard measures:
recommended), short circuit of wires or output terminals can
occur. The protection system will disconnect the speakers for
about 2 seconds. Do not test the safeguard system as this can
lead to failures not covered by the guarantee.
gher harmonic distortions (clipping) occur that cause damage,
in the first instance, of the twitters. In such a situation, the am-
plifier will disconnect the speakers for a period of about 2 se-
conds; this requires immediate turning down using the Volume
knob or the remote control.
For the sake of the natural environment, please remem-
ber that damaged amplifiers should be sent to speciali-
sed companies dealing in utilisation of electronic devi-
ces. Dispose of used batteries from the remote control
in special containers.
