Instructions for use

Thank you for purchasing the Nu-Vista Vinyl 2 by Musical Fidelity. Based on our excellent visitor tube technology, we decided to go all out “fully balanced” on the Nu-Vista range.

The Nu-Vista Vinyl 2 is the new flagship of Musical Fidelity phono preamplifiers, an ultra-high performance, highly accurate phono MM/MC phono preamplifier in beautifully designed and executed massive casework. We set out to make a phono stage without any practical limits. It’s designed in such a way to ensure you cannot overload the input stage or encounter any practical limitations in the output driving capacity. Its purpose is singular, to be a conduit for music. It exists to faithfully convey the artist’s intent, their emotions, the passion Compared to its predecessor, the Nu-Vista Vinyl, the Vinyl 2 now features entirely discrete and fully balanced audio circuitry on the inside. Read more in the introduction on page 6. Very large ranges from 40dB (voltage amplification by 100x) up to 69dB (voltage amplification by 3690x) are possible. The gain is cleanly switched using signal relays and you can see the big increase in amplification is why a phono preamp must be incredibly silent (a fully balanced design makes a big difference here) to handle amplification levels this high.

Input capacitance and impedance are switched by using JFET transistors. A costly, yet technically extremely sophisticated implementation, it allows the Nu-Vista Vinyl 2 to be matched with any cartridges and perfectly integrate it into the rest of your HiFi system.
The Nu-Vista Vinyl 2 displays our continued development of our Super Silent Power Transformers. Industrial grade power sockets with EMI filter and DC blocker stop interferences and eliminate transformer hum. The encapsulated toroidal transformer is purpose designed for delicate phono signals with low core saturation and extremely low electromagnetic radiation. Each discrete amp stage has a DC servo ensuring optimal DC mode. The preamplifier is powered by two high-quality symmetrical low-noise power supplies, one for each channel. All the fully balanced Nuvistor PSUs are passively filtered and regulated. If we are working with the few hundreds of microvolts from a phono cartridge, everything is playing its role; every decibel of signal to noise ratio is crucially important. Optionally, the Nu-Vista Vinyl 2 can be powered by the Nu-Vista Uni PSU (set to be released in 2024). This will achieve better noise performance, by moving the AC mains power supply from the main unit and build it into another matching box. We are taking advantage of the extra space to set up mains and output filtering a step above what is usually possible in one-box-solutions.

Also included is the Nu-Vista remote control which is a solid “Nu-Vista” style re-imagination of usual remote controls. Machined from solid, it has the same feel as the front panel of the unit, has a powerful beam, and runs off easily replaceable AAA batteries.
Used properly and carefully, it should give many years of outstanding musical reproduction. Dust regularly with a soft duster or soft brush, but be careful when using cleaning or polishing agents – they may harm the surface finish.
If there are any questions about the audio system, please consult the dealer, who is there to help and advise.

GENERAL ADVICE

Installation, Precautions & User Information
This new Nu-Vista Vinyl 2 is designed and built to provide trouble-free performance, but as with all electronic devices it is necessary to observe a few precautions:

• Heed all warnings shown on the back of the product.
• Only connect the Nu-Vista Vinyl 2 to a mains outlet having the same voltage as marked at the back of the unit.
• Always ensure that when disconnecting and reconnecting your audio equipment the mains supply is switched off.
• Position the mains lead and signal interconnects where they are not likely to be walked on or trapped by items placed on them.
• Do not use near water, or place water-filled containers on the Nu-Vista Vinyl 2, for example, a flower vase or potted plants. If water does spill inside, immediately pull out the mains plug from the wall socket and inform your dealer, who should then check the unit before further use. Entry of liquid into the Nu-Vista Vinyl 2 is dangerous, and may cause electric shock or fire hazard.
• Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment.
• Do not remove any covers or try to gain access to the inside. There are no internal adjustments or fuses you can replace yourself. Refer all service work to an authorised Musical Fidelity agent.
• Note: Unauthorised opening of the equipment will invalidate any warranty claim.
• Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents – they may harm the surface finish.

The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or damaged by lightning. For protection of the audio system during electrical storms, remove the mains plugs. If after-sales service is required, to help the dealer identify the Nu-Vista Vinyl 2 please quote the serial number located on the rear panel of the unit.

INSTALLATION

Introduction
Congratulations on the purchase of the new Nu-Vista Vinyl 2 phono- preamplifier. Great attention has been paid to internal layout, isolating each circuit section to prevent possible interaction. The unit features a finely tuned and tweaked Nu-Vista valve design, for smooth sound coupled with low noise and virtually no distortion. The Nu-Vista Vinyl 2 features entirely discrete and fully balanced audio circuitry on the inside. The phono preamplification contains three gain stages in fully Class A discrete transistor circuitry. The EQ stage doesn’t cut any corners either. Completely passive and in two separate stages (split-passive) – this is more costly to design and implement but ensures the most accurate representation of the ideal EQ curve. Split passive equalization allows for better impedance matching and lower deviation from the ideal EQ. In addition to the standard RIAA curve, we have implemented the two less common DECCA and COLUMBIA curves as well. RCA and XLR outputs both have their own individual stages allowing you to use them simultaneously.

Cleaning
Before cleaning the unit, switch off power at the mains switch and remove the mains plug from the wall socket. Clean the cabinets using a moist cloth. Using solvents, white spirit or thinners is not advised, as they could damage the surface finish.

Setting up
Position the Nu-Vista Vinyl 2 on a stable, horizontal surface where there is no risk of it being knocked. Make sure ALL units involved are switched off and unplugged from mains supply before making or removing any connections.

Important note:
During normal operation, the unit dissipates an appreciable quantity of power at all times, and it is important that it is well ventilated. The top and bottom are perforated to allow the smooth flow of heat through the unit. However, the unit must not be enclosed in a cabinet or placed where the ventilation holes are impeded as this could result in excessive heat build-up. The Nu-Vista Vinyl 2 must be protected from humidity – if the unit is moved from a cold place to a warm room, leave the unit for an hour or so to allow sufficient time for the moisture to evaporate.

Power Connections
The Nu-Vista Vinyl 2 is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the unit.

• Upgrade power connection:
  Optionally, the Nu-Vista Vinyl 2 can be powered by the Nu-Vista Uni PSU (set to be released in 2024) via the PSU RH Power, LH Power and Control connections. Please refer to the Nu-Vista Uni PSU manual for details.

Audio Connections

• Inputs: The Nu-Vista Vinyl 2 has two single ended (RCA) line level and two balanced (XLR) phono inputs. Choose the desired input to be used:
• Unbalanced RCA Phono Inputs: Connect turntables with RCA outputs to the relevant phono inputs (see page 8 for more information). Use good quality fully connected (signal and ground) phono cables for all RCA signal connections. Take care with positioning all input leads, try to ensure that they are well shielded and kept as far away from mains and speaker leads as possible. Connect the earth wire to the ground terminal.
• Balanced XLR Phono Inputs: Connect turntables with XLR outputs to the relevant phono inputs using good quality XLR balanced leads. Recommended lead wiring is shown on page 7. If your turntable with balanced phono output also has an earth wire, connect it to the ground terminal too. If not, just connect the XLR cables.
• Outputs: The Nu-Vista Vinyl 2 has a single ended RCA line level and a balanced XLR line level output. Both can be used simultaneously.
• RCA audio output: Use a good quality RCA phono audio cables (fully connected signal and ground), for optimum signal transfer.
• XLR audio output: Use good quality XLR audio cables (fully connected hot and cold signals and ground), for absolute optimum signal transfer.
• Mounting optional Spike Feet
  The Nu-Vista Vinyl 2 can optionally be used with spike feet. We recommend to ask a second person to help you lift the Nu-Vista Vinyl 2 for mounting the feet or felt pads.
  If you want to use the standard mounted feet, you can attach the big felt pads to those feet (remove the small rubber feet first if necessary).
  To mount the spike feet, screw the threaded rods into the spike feet so that the allen key side is inside the foot (this way, when you want to remove the foot from the amplifier again, you can unscrew the foot and then unscrew the threaded rod from the amplifier with an allen key, should it be too tight to unscrew by hand). Then screw the feet into the amplifier (remove the small rubber feet first if necessary). Attach the small felt pads to the bottom of the spike feet cups and place these cups under the spike feet.

The universal remote control shown below enables functions from this and related units to be operated from a convenient distance. Equivalent buttons on the remote control have the same functions as those on the front panel of the unit. Other functions are only available by remote control. As the handset uses an invisible infra-red light beam, the front edge must be pointed directly towards the receiver window at the front of the player, without visual obstruction between them. If the range of the remote control greatly decreases, replace the batteries with new ones. Do not mix old and new batteries – two are required, size AAA, LR03 or SUM-4.
Please dispose of used batteries in accordance to local regulations.

OPERATION

Starting
Once the Nu-Vista Vinyl 2 unit is correctly wired up, and plugged into mains, the Standby LED will light up. In this mode the Nu-Vista Vinyl 2 is consuming a minimal amount of power. To switch the unit on, press the Power button (4) on the front of the unit or the remote control. The display will now light up and the POWER LED will light up. The LEDs illuminating the Nuvistor valves will light up RED. This means the outputs are muted, and will remain in this state for about 12 seconds, so no sound will be heard. Once the delay is up, these LEDs go ORANGE, indicating the unit is ready for use, and any source material selected and playing will be heard. For the first 15 mins or so, the Nu-Vista valves are still warming up, and their LEDs stay ORANGE. After approx. 20 mins the valves will have reached full thermal equilibrium and are at their best performance, which is indicated by their LEDs turning BLUE.

Menu Navigation
Enter the menu by pressing Enter 6 or the up/down/right arrow button on the remote. Use the Back 5 and Enter 6 buttons to enter sub-menus or go a step back. On the remote this is done with the left and right arrow buttons. Confirm your setting with the Enter 6 button or the OK button on the remote. After 10 seconds of inactivity, the screen switches back to the main view.

• DOWN buttons on the remote.
• MM load settings: 50, 100, 150, 200, 250, 300, 350, 400 pF
• MC load settings: 5, 10, 25, 50, 100, 400, 800, 1k, 47k ohms

Tips on setting Gain and Load
For setting the various gain and loading characteristics, the cartridge manufacturer’s data sheets or setup information should be consulted. In a lot of cases the settings are not critical, and may even be changed to suit personal preference, if any audible differences are apparent. No damage will occur to an “incorrectly” loaded cartridge; at very worse a slightly impaired or nonoptimal frequency response and/or slightly increased distortion, both most likely to be inaudible, may result. Feel free to experiment with different gain settings on your own to match your turntable’s volume to other sources, if that is important to you. Or trust your own ear in finding out which gain and load setting make your particular cartridge sound best. Feel free to change the gain (or load) depending on which vinyl record you listen to. Some sound better with more, some sound better with less.

System settings

• Theme: using the menu screens under System Settings -> Theme you can set the display to dark or light mode.
• Brightness: using the menu screens under System Settings -> Brightness you can set the display brightness level. Setting the brightness to the lowest level turns the display off. When the unit is controlled, the display is briefly turned on and switches back off after 3 seconds of inactivity.
• Factory Reset: using the menu screens under System Settings -> Factory reset you can perform a factory reset. This resets all settings (audio, cartridge and system settings) to factory default values.
• About: using the menu screens under System Settings -> About you can view legal and firmware information.
