device, it is strongly recommended to act with great care. Please make sure that
there are no potential shorts circuits in the speaker cables.
An integrated protection circuit checks the output of the amplifier when it is powered
up. Should the load impedance be lower than 2 Ohms, this circuit will prevent turning
on the amplifiers main power supply, and the Status LED
the power amplifier should be turned off and all speaker connections should be
checked for short circuits. If everything seems in good order, please refer to the
speaker manufacturer. In the event that the loudspeakers have an impedance rating
below 2 Ohms, they cannot be used with the
For technical reasons the impedance check cannot be performed during normal
operation of the amplifier once the unit is powered up, meaning that there will not be
another impedance check before the unit is turned off ant powered up again. Shorts
that occur during normal operation will not be recognized and could lead to damage
or destruction of the amplifier. Once all connections are established, always turn on
the preamplifier first and the power amplifier last. The power down sequence should
be done in reverse order with the
This will prevent any audible pop from the preamplifier from being amplified, which
could damage the speakers, given the high power output capability of the
Monolog
amplifier.
To ensure optimum longevity of the output relays, it is recommended to power the
amplifier on or off without any programme material being played. This measure will
prevent sparking in the relays and thus save the relay contacts from premature wear.
Please bear in mind: the higher the output level, the greater the intensity of the spark.
Such sparks will increase the contacts serial resistance with time and thus lower the
amplifiers effective damping factor.
For cleaning purposes we recommend to use only a slightly damp lint-free cloth. If
necessary, use a mild alcohol-free household cleaner. Avoid strong cleaning agents
or detergents as they may degrade the finish. For safety reasons always disconnect
the unit from AC mains and check all connections before restoring power to your
