Unison Research Unico 90 Instruction Manual

14
L’Unico90 has two LEDs which provide the user with important
information about the operating condition of the amplifier.
LED INPUT AND LED VOLUME ON:
indicates normal operation
LED INPUT AND LED VOLUME blinking (fast):
indicates automatic start-up phase (approx 40 seconds)
LED INPUT AND LED VOLUME blinking (slow):
indicates intervention of the thermal protection device, power stage
is switched off.
When the internal temperature has returned to normal the amplifier
will switch on automatically and repeat the initial start-up phase.
It is advisable to switch off if the amplifier if the thermal protection
device intervenes. This will speed up return to normal operation
LED INPUT ON e LED VOLUME blinking:
indicates that the amplifier is receiving a signal from the IR remote
control (volume changing).
If there is a temporary loss of mains electricity (even of very short
duration) the amplifier will restart in automatic start-up mode.
REMOTE CONTROL
Unison Research

amplifiers are supplied complete with infrared
remote control.
Your remote control handset is fitted with a battery type CR2032 -
3V (lithium battery).
IMPORTANT! The use of the remote control with Unico 90
allows only volume control by acting on Vol- e Vol+ buttons.
