Cyrus III Amplifier OPERATION
Volume Control
Remote Control Handset
as supplied with Cyrus III only
In normal mode the rotary knob of the Cyrus
III controls the volume in 1dB steps from its maximum level down to the minimum. The light ring around the knob is calibrated to give the correct loudness scale to the changes in the volume level. When the volume is set to the minimum level the first L.E.D. indicator on the light ring will be RED. The currently set volume is preserved when the unit is put into standby mode. Should the level be set abnormally high when standby is selected, this will be automatically adjusted down to a safer level on switch-on.
Balance Control
Your Cyrus III is equipped with a Balance control key
3
which is used to change the operation mode of the rotary knob to that of Left - Right Balance. When selected, the light ring will change function to work in "reverse ­video" format with the unlit section indicating the position of L-R balance.
When in this mode, you can control the L-R balance by up to +/-4dB as well as switching one channel off completely when the control is turned to an extreme. The balance mode is automatically reset after 5 seconds of inactivity of the rotary knob. It can also be reset by pressing the balance key again.
Mute
Pressing the Mute Key

Cyrus III Amplifier ADDITIONAL INFORMATION
KNOW YOUR CYRUS III
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.
Signal Processors
13
English
ADDITIONAL INFORMATION Cyrus III Amplifier
A multitude of signal/sound processing components
such as Dolby Pro-Logic sound processors may be used with the Cyrus III by connection inside the "Tape Loop" of the amplifier. In this case the tape recorder is normally connected to the processor instead. For detailed connectivity refer to the relevant component's manual.
Bi-amping / Tri-amping
The buffered pre-amplifier output of the Cyrus III
may be used in conjunction with added power amplifier blocks to upgrade your loudspeaker system through Bi-amping or Tri-amping. In this case you should check that the sensitivity of the power amplifier modules are compatible with the output level of the Cyrus III.
External Regulated Power Supply - PSX-R
Addition of a PSX-R which is a highly regulated DC
power supply will upgrade the sonic performance of your Cyrus III as well as enhancing its current drive ability into difficult loudspeaker loads. Should you decide to add this optional extra to your system, be sure to have your Cyrus III converted by your dealer or an authorised Cyrus Service Organisation.
When Cyrus III / PSX-R combination is installed all
analogue and signal related sections of the Cyrus III are powered from this clean and highly stable power source, while the remaining power requirements are supplied internally. This technique ensures complete isolation of the sensitive analogue sections from the control side as well as the AC mains-borne noise and power supply ripple which of course, enhances the delicacy and transparency of the reproduced music programme.
MC-BUS System Connection
This is an optional connection via the MC-Bus
11
sockets
(see rear panel drawing on page 4), which
can provide unified power control of a complete Cyrus system from your Cyrus III. The MC-Bus connections should be wired as a 'loop' using single RCA phono interconnects. The diagram on the next page shows a typical Cyrus system of Cyrus DAD7, Cyrus FM7, Cyrus III and Cyrus Power with such an MC-Bus loop connected. Referring to this diagram, connect the first cable between the MC-Bus output of the Cyrus III and the MC-Bus input of the next Cyrus component. Continue to wire each product MC-Bus output to the next input, finally returning to the Cyrus III input to complete the loop.

which ensures consistency and quality levels hitherto impossible to achieve in an audio product of this price range.
AMPLIFIER MAINTENANCE
There are no user serviceable parts in the Cyrus III so there is no reason to remove any of the panels. After disconnecting the mains power supply, the cabinet may be cleaned using a chamois leather, slightly moistened with water. DO NOT use cleaning agents containing alcohol, spirits, ammonia or abrasives.
When the above connections have been made it will
now be possible to control the power function of the entire system from the Cyrus III, either from the front panel or by remote control. Selecting 'CD' from the
Cyrus III front panel will then switch on the Cyrus III, the Cyrus Power and the Cyrus DAD7 CD player.
When the Cyrus III is set to Standby, all system components will also switch off.

Another important function of the MC-Bus system is
to enable Micro-processor controlled testing and calibration to be applied during the production phase of the Cyrus range of products. Using the MC-Bus all possible tests relating to the correct operation of the system are performed in a relatively short period of time. Such rigorous tests are only possible with the aid of this proprietary communication bus system

TROUBLESHOOTING Cyrus III Amplifier
TROUBLESHOOTING GUIDE
If you suspect that your Cyrus III is not operating to specification please read through this section before returning the amplifier to your local dealer.
No Sound from either Speaker
Check that the amplifier is on. Green power light
should be "ON".
Check that the amplifier responds to different front
panel commands.
Check that the MUTE light on the volume control
light ring is "OFF".
Check that the relevant programme source is selected
and is working. For example the CD Player is playing.
Check that the Tape Monitor is not selected
inadvertently, RED light above the TP key is "OFF".
Check that the loudspeakers are not inadvertently
disconnected.
Check that the installation is correct according to the
installation guide in this booklet.
No Sound from one Speaker
Check the Balance Control is not set to left or right
limits.
If your loudspeakers are fitted with protection fuses,
check that the fuse is intact.
Check the interconnect cable integrity on the rear
panel and at source. If possible use another interconnect cable.
Check the speaker cable connection integrity of the
missing channel.
If the problem persists proceed as follows:
Change the programme source using the suspected
interconnect cable and check that the problem still exists. If the fault is removed by doing this then the original source is at fault.
Interchange the left and right connection of the
interconnect cable at SOURCE. If the missing channel switches over then there is a problem in one channel of the source or the interconnect. If the sound disappears totally then there may be two problems present in your system.
Check that there is not fault indication on your Cyrus
III front panel. If so refer to the next section.
English
16
Change over the left and right channels of your
loudspeaker on the Cyrus III rear panel. If the problem stays in the same channel, then there is a
Cyrus III Amplifier TROUBLESHOOTING
fault in the loudspeaker cable or the loudspeaker. Now switch the cable at the loudspeaker end and if the problem switches then the loudspeaker is faulty, otherwise it is the loudspeaker cable which may be defective.
Note:
Be sure to restore the system to its original configuration after completion of the above series of tests.
Spurious Sounds from the Loudspeakers
If you experience strange or unnatural noises from your system proceed as follows:
Select another source to ensure that this is not a
common problem. If the problem remains switch the Cyrus III off at the rear panel and turn it on again after a few seconds.
If the problem is limited to a single source, check the
integrity of the interconnection to the source and in the case of a phono turntable, check that the phono ground wire is secured at the rear panel of the Cyrus
III.

TROUBLESHOOTING Cyrus III Amplifier
FAULT INDICATION SYSTEM
The Cyrus III has a unique fault indication system, built in to help you to diagnose the possible cause of a problem. All fault indications are presented by the Standby light on the front panel of your Cyrus III.
FAULT INDICATION AT FIRST INSTALLATION
Flashing RED
This indicates that the Cyrus III has been adjusted for
use with a PSX-R power supply, but a PSX-R has not been connected correctly. In this case, check that the
PSX-R umbilical cord is connected to the rear panel PSX-R socket and that the mains power is connected
securely to both products. If the connections are in order and the indication persists, return the unit(s) to your Mission distributor.
Flashing GREEN
This indicates that a PSX-R power supply has been
connected to a Cyrus III without the correct preparation for PSX-R use. In this case, remove the
PSX-R cable and re-test the Cyrus III. If the Cyrus III functions correctly, return
the amplifier to a Mission distributor for PSX-R adjustment.
FAULT INDICATION WHEN IN USE
Flashing GREEN / YELLOW
This indicates an overload condition in at least one
channel. If the problem is of a temporary nature (for example excessive volume setting), normal operation will resume after four seconds. If the fault indication persists, there may be a problem with the loudspeakers or their connections. In this case, switch off the power at the rear of the Cyrus III and disconnect the speaker cables from the rear panel. If the fault indication has now cleared, check the loudspeakers, cables and plugs carefully for loose strands of wire which may cause a short circuit.
Flashing RED
This indicates an internal problem with the Cyrus III
or PSX-R (where used). If the problem does not clear when the amplifier power is reset, return the unit(s) to your Mission distributor for checking.
Flashing GREEN
This indicates a fault reported from the PSX-R. In this
case, switch off the power to both the Cyrus III and the PSX-R and switch on again. If the problem does not clear, return both units to your Mission distributor for checking.
