Frequently Asked Questions - Phono X Cyrus Audio

How do I connect a turntable with a moving magnet (MM) cartridge?

Connect the turntable to the Moving Magnet Input (③ on the rear panel). Ensure the cartridge is a regular MM type or a high-output MC recommended for MM input.

How do I connect a turntable with a moving coil (MC) cartridge?

Connect the turntable to the Moving Coil Input (② on the rear panel). Use the MC Loading Switch (①) to set the load impedance (10Ω, 100Ω, or 1kΩ) as recommended by your cartridge.

What is the MC loading switch for?

The MC loading switch adjusts the load impedance for your moving coil cartridge. Settings of 10Ω, 100Ω, and 1kΩ are available, with optional capacitance loading (1nF) for cartridges that require it.

How do I select between RIAA and IEC equalization?

Press the IEC key (③ on the front panel) to select IEC response. When the indicator above the key is lit, IEC is active; when unlit, traditional RIAA response is used.

Why is there no sound coming from my speakers?

Check that the Phono X and system are not in Standby, the correct input (MC or MM) is selected, all system amplifiers are powered on, and the volume is not at minimum. Verify connections.

Why do I hear a hum or interference?

Hum is often caused by a poor tone arm ground connection. Ensure the turntable's grounding wire is connected to the appropriate ground terminal (⑨) on the Phono X. Interference from appliances may also cause hum; reposition equipment.

Can I use the PSX-R external power supply with the Phono X?

Yes, the PSX-R is an optional external regulated power supply that plugs into the PSX-R connector (⑥) on the rear panel, powering analogue sections with a clean DC source.

How do I set up the MC-Bus connection with my Cyrus amplifier?

Connect the Phono X to the recommended AUX input of your Cyrus amplifier and use the MC-Bus connections (⑤) to enable automatic switching. Refer to your amplifier handbook for details.

Connecting a Turntable

The Phono X accepts Moving Coil and Moving Magnet cartridge inputs.

If you have two turntables, one equipped with a MM and one with an MC cartridge, both can be connected at the same time.

Before connecting a turntable to the Phono X, check the specification of the cartridge which is fitted, then connect the turntable to the correct input of the Phono X by referring to the following paragraphs.

Moving Magnet Input:

The MM input ③ accepts:

• Regular moving magnet cartridges
- High output moving coil cartridges (where MM input is recommended by the cartridge manufacturer)
• Low output MC cartridges connected via step-up transformers

Moving Coil Input:

The MC Input ② accepts:

• Low-output moving coil cartridges.

Your Phono X is provided with a loading switch ① so that you can set the correct load impedance for your MC cartridge. Three settings are available, 10Ω, 100Ω and 1KΩ. Unless your cartridge instructions recommend a lower value, we suggest you use the 1KΩ setting.

Some MC cartridges are load sensitive and may also require a capacitance load to control high frequency response peaks. Each load setting is therefore available with or without a 1nF shunt capacitor. The shunt settings occupy the last three positions on the switch. Use capacitance loading only if your cartridge instructions specifically advise its use.

Shorting plugs

The Phono X is supplied with two shorting phono plugs. When using only one input, insert these plugs into the unused input.

Note: These plugs must be used only as described above.

Ground Connections

Most turntables include a separate grounding wire.

There are three grounding systems in common use:

1. The motor and tone arm grounds are connected to a common ground wire. Connect this wire to either the MM or MC ground terminal ⑨, depending on the cartridge used.
2. There are two ground wires, one from the motor and one from the tone arm. Connect both wires to the appropriate ground terminal on the Phono X.
3. There is no separate ground wire. Some units use the signal cable outer return for turntable and tone arm grounds. Though not best practice, the method is acceptable. No separate ground connection will be necessary.

Some cartridges link a negative signal pin to the metal shield. This link may make contact with the tone arm metalwork and cause a hum loop. If you think this is the case with your turntable, ask your dealer before you remove the link.

If you have an amplifier that requires a mains earth, do not use the MM or MC ground terminals of the Phono X for this purpose. Use an appropriate ground terminal on the ancillary equipment.

Output Connections

Connect the output sockets ④ of the Phono X to a line level (AUX) input on your pre-amplifier. When connecting the Phono X to a Cyrus amplifier, the AUX input labelled AU, AU1 or AUX/PH is recommended.

All signal connections should be via high quality audio interconnects. The convention for phono connections is Right Channel RED, Left Channel WHITE or BLACK.

External Regulated Power Supply - PSX-R

The PSX-R is a unique DC power supply which will upgrade the sonic performance of your Phono X. When a Phono X & PSX-R combination is installed, analogue and signal related sections of the Phono X are powered from this clean, stable power source while other requirements are supplied internally. This ensures complete isolation of control circuits and sensitive analogue sections reducing AC mains-borne noise and power supply ripple.

To connect the PSX-R to the Phono X plug the connector on the umbilical cord of the PSX-R into the Multi-Pole socket on the rear of the Phono X ⑥. You will need a mains supply for both units.

OPERATION (Refer to fig 2)

Power Control

The mains power to the Phono X should normally be left on unless left unattended for a long period when the mains power at the wall socket should be switched off or the product disconnected from the AC supply. When power is applied, the Standby key ① is used for power control. The Standby light ② shows red when the Phono X is in Standby and green when operational.

Selecting an Input

Depress the MC ⑤ or MM key ④ to select the appropriate input. The red indicator above the selected input key will turn on.

Playback Equalisation

The Phono X offers the choice of traditional RIAA playback response or the newer IEC response. For most systems built from quality audio components, Cyrus recommends the original RIAA response. If your turntable is prone to feedback or rumble and/or your loudspeakers have extended bass response, switching to the IEC setting will help to reduce bass noise and distortion. The IEC response is also useful to reduce large cone excursions due to warps.

1. Press the IEC key ③ to select IEC response.

The red indicator above the key will turn on. When the IEC indicator is not lit, RIAA response is selected.

Mc-Bus System Connection (Optional)

This feature is usable if you own a Cyrus amplifier. By connecting the Phono X to the recommended AUX input of your amplifier and setting up MC-Bus connection for the system, the amplifier will switch on the Phono X whenever the AUX input is selected. Refer to the relevant amplifier handbook for MC-Bus wiring instructions.

If preferred, the MC-Bus response of the Phono X can be reconfigured to always switch on with the amplifier, regardless of which input is selected. This may be useful if the Phono X is connected to an input other than AUX. To change the MC-Bus response, follow this sequence:-

1. Set the Phono X to Standby.
2. Press the IEC key ③. and hold it down for two seconds, the indicator above the IEC key will flash.
3. Take the Phono X in and out of Standby to register this setting.

To restore normal operation:

1. Repeat Steps 1 & 2 above, the IEC indicator will flash twice.
2. Take the Phono X in and out of Standby to register this setting.
