Power-on sequence:
During
normal operation, when
ULTIMA 2 is in standby mode
the large power button on the front
panel will illuminate red. To power-on
ULTIMA 2 press the large power button
once until you feel a click. ULTIMA 2’s
power button will now change to green,
while 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 teal.
Earthing issues:
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 2 on or o
ff
.
Please refer to the diagram below to
correctly wire your 12V trigger.
When a 12V trigger is sensed by
ULTIMA 2 the colours displayed on
power button will be di
ff
erent.
During standby, the large front-panel
power button will illuminate red, then
orange when triggered on and the
safety checks are being performed.
During this stage do not increase the
gain on the input device. Once the
amplifier becomes operational the
power button will display a continuous
purple glow.
Adjusting the brightness of the LEDs:
At any time, you can adjust the
brightness of the LEDs to suit your
listening environment. Simply locate
the hidden button in the middle of the
faceplate as indicated below, insert a
thin object and push until you hear an
audible ‘click’. The light ring and power
button will cycle between low and high
brightness modes.
0V / Ground
+5V to +12V
WARNING:
In the
rare event that a
fault is detected
the amplifier will
switch itself o
ff
. If this
occurs discontinue use
immediately and seek
help from your Chord
Electronics retailer.
