N. America / Far East - 115V

T400mA/20mm

In the U.K., the Cyrus aCA7 power lead is supplied fitted with a mains plug. If the plug fuse should need replacing ensure that it is replaced only with a 3 Amp Fuse.

CONNECTING A CYRUS PSX-R

If a Cyrus PSX-R is to be used with the Cyrus aCA7, connect the umbilical cord of the PSX-R to the 5-pin Cannon input socket of the Cyrus aCA7. When correctly fitted the connector will latch into place in the socket.

No other connections or internal modifications to the Cyrus aCA7 are needed for PSX-R connection.

Note: Please ensure that the Cyrus aCA7 and the PSX-R are unplugged from the mains before connecting the units.

When a PSX-R is in use, both the Cyrus PSX-R power supply and the Cyrus aCA7 will require mains power. For more details refer to the Cyrus PSX-R Instruction Manual.

CONNECTING SOURCE INPUTS

Connect a quality RCA phono cable between each system component and the appropriate rear panel socket. Observe the colour coding of the phono cable for left and right channel identification. The standard convention is– Right Channel RED, Left Channel WHITE or BLACK.

The Cyrus aCA7 provides connections for a CD Player – CD ⑬, a tuner – TU ⑫, an Audio Visual processor– AV ⑪, two auxiliary inputs– AUX1 ⑩ and AUX2 ⑨ and two tape decks TP1 ⑧ and TP2 ⑦.

The AUX inputs can be used for connection of a wide variety of products such as a second CD player, an electronic keyboard, etc.

Always check the technical specification of source products before connecting them to your Cyrus aCA7. Consult your dealer if in doubt.

CONNECTING A TURNTABLE

The Cyrus aCA7 is a line level pre-amplifier. To play a turntable through your unit you require an external phono pre-amplifier. The Cyrus aEQ7 phono pre-amplifier is available from Cyrus which fully integrates with the Cyrus aCA7 and has comprehensive facilities for both moving coil and moving magnet cartridges.

CONNECTING A TAPE RECORDER

Two tape decks may be connected to the Cyrus aCA7.

Tape 1 is suitable for all tape decks and other recording units but does not feature off-tape monitoring.

Tape 2 has a conventional tape loop with full monitoring facilities suitable for all tape decks including three-head models with off-tape monitoring.

To connect a tape recorder:

Firstly, connect a phono cable from the Output or Playback sockets of the tape recorder to the required Tape Input sockets- ⑦ or ⑧ of the Cyrus aCA7. Now connect a second phono cable from the Input or Record sockets of the tape recorder to the Tape Output sockets ⑤ or ⑥ of the Cyrus aCA7.

A three head tape recorder should be connected to the Tape 2 sockets. For other units we suggest Tape 1.

For a fuller treatment of recording topics refer to Additional Information on page 12. Refer to your recorder handbook if you are in any doubt.

CONNECTING HEADPHONES

The HEADPHONES socket ① is a standard 1/4 " stereo jack socket for connection to a pair of conventional headphones. It should not be used with Electrostatic units.

CONNECTING A POWER AMPLIFIER

The Cyrus aCA7 must be connected to a power amplifier in order to drive the system loudspeakers. RCA phono and Balanced XLR connection systems are provided, the appropriate connection depending on each individual installation. Where the Cyrus aCA7 is placed close to the power amplifier we recommend using the RCA phono connections. If the power amplifier is some distance from the Cyrus aCA7 (e.g. beside the loudspeakers) balanced XLR connections may give improved performance.

Connecting RCA phono cables to a power amplifier

Two pairs of RCA output sockets (PRE OUT) ③ and ④ are available on the Cyrus aCA7. Connect a quality phono cable from one PRE OUT pair to the left and right inputs of the power amplifier. The other pair may be used for bi-amping, etc. – see Additional Information on Page 12.

Connecting Balanced XLR cables to a power amplifier

Connect a 3 pin XLR cable between each channel of the Cyrus aCA7 balanced outputs ⑰ and ⑱ and the corresponding XLR input of the power amplifier.

Note: If RCA and XLR outputs are simultaneously used to power two stereo amplifiers (or two monobloc pairs), they must all be Cyrus units. Never connect RCA and XLR cables to alternate channels of the same amplifier.

POWER CONTROL

Refer to figure 2, front panel drawing on page 7.

The STANDBY key ② is used for power control. The Standby light ③ will show Red when the Cyrus aCA7 is off and Green when operating. Selecting any input source will also switch on the Cyrus aCA7.

SELECTING AN INPUT

The INPUT SELECT keys ⑨ - ⑬ switch between selected input sources. When an input key is selected, the red indicator above the key will turn on.

TAPE PLAYBACK

To replay a tape source connected to the TAPE 1 sockets press the TP1 key ⑧.

To replay a tape source connected to the TAPE 2 sockets press the TP2 key ⑦. The indicator above the TP2 key will now light in addition to the selected source. A further press of the TP2 key will return to the current selected source.

Additionally, the Tape 2 input provides an off-tape monitor facility. If your tape deck is equipped with three-heads, selecting the TP2 key enables a recording to be monitored, whilst recording.

TAPE RECORDING

The signal from the selected source is sent to Tape Recorders connected to both TAPE 1 and TAPE 2 circuits automatically. Tape recordings may therefore be made from the selected source to either, or both of the Tape Recorders. In addition, tape copying is possible by playing the tape recorder connected to the TAPE 1 input and recording to TAPE 2 (See Page 12 for a fuller treatment of tape recording).

VOLUME CONTROL

The LEVEL CONTROL ⑥ of the Cyrus aCA7 performs the dual functions of volume and balance. The light ring display around the rotary knob indicates either volume or balance depending on the current mode of operation.

The Level Control of the Cyrus aCA7 controls the volume level in 1dB steps. The light ring around the knob is calibrated to show the current loudness level. When the volume is at minimum the first indicator on the light ring will be RED. As the volume increases, a GREEN light will move clockwise around the ring.

BALANCE CONTROL

The Cyrus aCA7 is equipped with a BALANCE key on the remote handset. Page 11 has the full procedure for adjusting channel balance.

MUTE

Pressing the MUTE Key ① will fade the volume to minimum. The RED minimum level indicator will light in addition to the existing GREEN light to show that the output is muted. Moving the volume knob or pressing the Mute key fades the signal up to the original setting.

If the level was set very high when the Cyrus aCA7 was muted, when unmuted it will return at a safe lower setting.

USING HEADPHONES

The HEADPHONES key ④ on the Cyrus aCA7 front panel is a special form of Mute switch. When you press the HEADPHONES key, the main output from the Cyrus aCA7 to the power amplifier is muted so that you can listen to the headphones without the speakers. To restore loudspeaker operation, press this key again.

When Headphones operation is selected, the MUTE light at the bottom of the light ring will glow Orange

Note: The HEADPHONES key is operational only when headphones are connected.

Caution: If you have been listening to headphones at high volume, be sure to turn the level down before you switch to normal loudspeaker operation.

Volume and Mute Indications

Normal listening level Orange mute- ‘phones Red mute- Full mute

Normal listening level Normal operation

The Cyrus aCA7 always reverts to its last setting when the MUTE key is toggled. If, when listening to headphones (Orange mute on) you press the MUTE key, the Mute light will change to Red and the full system will mute. If you press the Mute key again the Orange mute light will return.

Standby

If you set the Cyrus aCA7 to Standby when you are in Headphone mode, when you next bring the unit out of Standby it will revert to Headphone operation.

If you unplug the headphones after you have set Standby, when you next switch on the Cyrus aCA7, loudspeaker operation will be restored.

Refer to Additional Information on Page 12 for more details.

Press - △ to move the channel balance to the Left.

Press the △▲ key again to restore normal Volume mode.

If you leave the Cyrus aCA7 set to Balance, after 5 seconds of inactivity the mode automatically reverts to indicate volume level.

As an alternative to using the handset keys to adjust the balance, you may use the △▲ key to select balance mode and then adjust the balance using the Level Control on the front panel.

Mute

Pressing the MUTE key ⑩ fades the main volume to zero.

Pressing the MUTE key again restores the volume to the level it was at prior to selecting Mute (unless the volume was set very high in which case the Cyrus aCA7 will restore at a safe lower level of -15dB).

You cannot select or deselect headphones via the handset.

SYSTEM OPERATION WITH THE COMMANDER

When a Cyrus CD player, FM7 tuner and suitable ancillary units are connected to the Cyrus aCA7, integrated system operation is possible using the Remote Commander handset (see page 17 for details).

KNOW YOUR CYRUS aCA7

Power

• When first powered from the mains, the Cyrus aCA7 will run a self-test and then revert to Standby. When first switched on from standby the CD input is selected and the volume is set to minimum.
• When the Cyrus aCA7 is set to standby after a period of use, Input selection and Volume/Balance settings are retained. If the unit is put in standby while set to a very high volume level, the Cyrus aCA7 will power on at a safe level of -15dB when next switched on.
  • These conditions also apply to the Mute functions.
• When switched to Standby, the audio circuits of the Cyrus aCA7 are shut down for optimal safety.

Volume and Balance

• The volume control system of your Cyrus aCA7 is a musically transparent precision 1dB - step attenuator. This design is precise to limits of +/-0.1dB throughout all 86 steps of attenuation available.
• As the volume setting of your Cyrus aCA7 is achieved independently for Left and Right channels, channel balance can be controlled with precision by applying an offset to either channel. Channel balance is maintained to +/- 0.2dB across the entire range.

Bi-amping / Tri-amping

• In addition to the balanced output, there are two sets of RCA sockets on the Cyrus aCA7. This enables you easily to connect additional power amplifier blocks to upgrade your loudspeaker system for Bi-amping or Tri-amping. Stereo and Monobloc amplifiers are available from Cyrus for this application.

Powering each drive unit separately increases maximum output and dynamic range and, with each amplifier driving a limited frequency band, clarity imaging and transparency are all greatly improved.

NOTES ON RECORDING

Unless you own a 3 head tape deck, your recording unit whether MD, DAT or CD-R will not have true playback monitoring so you may use Tape 1 or Tape 2. If you have two recording units, say MD and cassette deck, we suggest you connect the MD player to Tape 1 and the cassette deck to Tape 2 for greater flexibility.

Note: You cannot record from Tape 2 to Tape 1.

Many high quality VCRs produce acceptable audio recordings and their long tape times are useful. Even without an AV processor, by using your VCR in conjunction with the Cyrus aCA7 the audio component of your TV and Video programmes will be hugely improved. Consult your dealer for advice if in doubt.

PROGRAMMABLE INPUT SENSITIVITY

In all audio systems, there will be audible changes in volume when switching from one source to another because source component output levels vary. To compensate for this, each input of the Cyrus aCA7 can be matched in level with reference to the CD input.

To alter an input level:-

1. Select CD input on the Cyrus aCA7 and set the volume control to a comfortable listening level.
2. Select the required input (tuner, etc.) on the Cyrus aCA7 front panel. Keep the input key pressed and the display will change to indicate input offset (see diagrams).
3. Adjust the level control to give the same audible volume as the CD player. The display indicates the offset applied.
4. Store the offset by pressing the input key again.

To restore the factory settings, follow steps 2 to 4, setting the display to 'zero offset' - see the diagram below

This display shows the factory setting for the Cyrus aCA7.

It indicates that the selected input has the same sensitivity as the CD input (zero offset display).

This display shows that the selected input (e.g. tuner) has been programmed to be 2dB more sensitive than the CD input. This will increase the sensitivity of the tuner input to give equal volume levels from CD and tuner.

This display shows that the selected input (e.g. AV) has been programmed to be 4dB more sensitive than the CD input. This will increase the sensitivity of the AV input to give equal volume levels from CD and the AV unit.

MC-BUS AUTO-CALIBRATION - AV-MASTER

When a Cyrus AV master is wired into the MC-BUS loop, precise volume calibration will take place when the AV input is selected on the Cyrus aCA7. Refer to your Cyrus AV-master handbook for further details.

PSX-R REGULATED POWER SUPPLY -

The PSX-R is a highly regulated DC power supply. Its use will upgrade the sonic performance of your Cyrus aCA7. No adjustments are necessary when connecting the Cyrus PSX-R to the Cyrus aCA7 - full connection instructions can be found on page 5.

MC-BUS SYSTEM CONNECTION

The MC-Bus system (see drawing on page 4) can provide unified power control of a complete Cyrus system from your Cyrus aCA7. MC-Bus connections are wired as a 'loop' with single RCA phono interconnects. The diagram below shows a typical Cyrus system of Cyrus CD Player, Cyrus FM7, Cyrus aCA7 and Cyrus Power Amplifier with the MC-Bus loop connected. Connect the first cable between the MC-Bus output ② of the Cyrus aCA7 and the MC-Bus input of the next Cyrus component. Continue to wire each MC-Bus output to the next input, returning to the Cyrus aCA7 input to complete the loop.

OPERATION WITH MC-BUS CONNECTED

When MC-BUS connections have been made it is possible to control the power function of the entire system from the Cyrus aCA7.

For example, if you select 'CD' from either the Cyrus aCA7 front panel or the Audio Commander, you will switch on the Cyrus aCA7, the Cyrus CD player and any connected Cyrus Power amplifiers.

When the Cyrus aCA7 is set to Standby, all system components will also switch off.

TROUBLESHOOTING GUIDE

If you suspect your Cyrus aCA7 is not operating to specification, check carefully all connections using the installation section of this handbook. If problems persist, the checklists below may help.

Ensure the power to all units is switched off before altering any connections and only switch the power on again when the new connections are fully made.

No Sound from either Speaker

• Check that the pre-amplifier and the power amplifier is on. The standby light should be green.
• Check that the pre-amplifier responds to different front panel commands.
• Check that the MUTE light on the volume control light ring is completely "OFF" -( see Page 9).
• Check that the relevant programme source is selected and is working (e.g. the CD Player is playing).
• Check that the Tape Monitor (Tape 2) is not selected inadvertently.
• Check that the headphones work normally.
• Check both the input and speaker connections to the power amplifier.

No Sound from one Speaker

• Check the Balance Control is not set to extreme limits.
• If your loudspeakers are fitted with protection fuses, check that the fuse is intact.
• Check interconnect cable integrity on the rear panel and at source. Try another interconnect cable.
• Check the interconnect cable integrity between the Cyrus aCA7 and the power amplifier.
• Check the speaker cable integrity of the missing channel at the power amplifier and loudspeaker.

If the problem persists:

• Change the programme source using the suspected interconnect cable and check that the problem still exists. If the fault clears the original source is at fault.
• Interchange the left and right connections 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.

Note: 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 aCA7 off at the mains or disconnect the mains plug. Replace the mains plug after a few seconds and restore power to the Cyrus aCA7. If the fault persists or you are in any doubt, consult your dealer.
• 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 associated cartridge pre-amplifier.

FAULT INDICATION SYSTEM

The Cyrus aCA7 has a fault indication system to help you to diagnose the cause of a problem. Fault indications are presented by the Standby light on the front panel.

- Flashing RED

There is a problem with the internal power supply of the Cyrus aCA7. Switch the unit off at the mains and switch on again after a few seconds. If the indicator still flashes, return the unit to your dealer for attention.

Fault Indications involving PSX-R connections

- Flashing RED

A PSX-R that is switched off is connected to the Cyrus aCA7.

A PSX-R has been disconnected while the Cyrus aCA7 is operating.

There is a fault with the internal power supply of the Cyrus aCA7.

- Flashing Green

A PSX-R has been connected while the Cyrus aCA7 is in normal operating mode.

In all the above cases you should switch all units off, fully disconnect the PSX-R, and switch on the aCA7 again.

If normal operation resumes, switch the Cyrus aCA7 off and re-connect the PSX-R following the instructions on Page 5 of this manual. The system should now work normally.

If the fault indications persist, return the suspect unit to your dealer for attention.
