POWER-ON SEQUENCE:
During normal operation, when
Ultima is in standby mode the
large power button on the front panel
will illuminate an red colour. To power-
on Ultima press the large power button
once until you feel a click. Ultima’s
power button will now change to a
green colour whilst it begins its initial
safety checks.
During this phase do not increase the
gain on the input device as you cannot
determine its final amplified volume
which can damage the connected
speakers.
Once the amplifier has passed the
safety check and is operational,
after approximately ten seconds, the
amplifier will display a teal colour.
In some European countries,
a hum or buzz may occur if
the amplifier is connected
to mains sockets that do not have an
earth or adequate earth. If this occurs,
please ensure that your equipment is
connected via a good-quality multi-way
mains block which contains an earth
point at every socket outlet.
We recommend that an earthing
method for your building is
implemented.
12V Trigger: A 12V trigger can be
used to remotely turn Ultima on or o.
Please refer to the below diagram to
correctly wire your 12V trigger.
When a 12V trigger is sensed by Ultima
the colours displayed on power button
will be dierent.
During standby the large power buton
on the front panel will illuminate an
orange colour, however just like the
power sequence without the 12V
trigger a green colour will be displayed
once you switch the unit on and it
performs its safety checks. You should
still not increase the gain on the input
device.
Once the amplifier becomes
operational the power button will
display a continuious purple glow.
0V / Ground +5V to +12V
WARNING: In the
rare event that a
fault is detected
the amplifier will
switch itself o. If this
occours discontinue use
immediately and seek
help from your Chord
Electornics retailer.
