Power
• When first powered up from the mains switch on the
rear panel, the Cyrus III will run a self-test, checking
the internal functions and all the front panel
indicators in sequence. After completion of this cycle
the amplifier will revert to Standby mode. When first
switched on from standby the CD input is
automatically selected and the volume is set to
minimum.
• When set to Standby the front panel settings for input
selection and Volume/Balance will be retained until
next used. If the unit is put in standby mode while set
to abnormally high volume levels, the Cyrus III will
power on at the safe level of -15dB when next
switched on.
• When switched to Standby, the power amplifier
section of the Cyrus III is shut down to ensure
minimal power consumption and reduced heat
generation.
• If other Cyrus products are used with the Cyrus III,
they can be connected via the MC-BUS as shown on
page 15. This will ensure that the power ON/OFF
will function in unison between all Cyrus products,
locally as well as via the remote control handset. For
example, if the tuner input - TUN of the Cyrus III is
selected, them the FM7 tuner will automatically turn
on. Conversely if the Standby key on the Cyrus III is
pressed, then all Cyrus products connected via the
MC-BUS will turn off.
• The Cyrus III runs at a high quiescent current setting
to ensure deep operation into class AB. This naturally
results in the enclosure to be warm to the touch and
therefore should not be a cause for concern.
Volume and Balance
• The volume control system of your Cyrus III is a
precision 1dB - step attenuator design which is
musically transparent. One major advantage of this
design is its absolute accuracy, which unlike
conventional volume pots maintains +/-0.1dB
tolerance throughout 63 steps of attenuation
available.
• The volume setting of your Cyrus III is achieved
independently for the Left and Right channels. The
L-R channel balance can therefore be controlled by
applying an offset to the attenuation of one channel
with respect to the other with the same degree of
precision. The channel balance is maintained within
+/- 0.2dB across the full volume control range.
