MUTEC REF10 Digital Audio Equipment Instruction Manual

MUTEC REF10 Digital Audio Equipment Instruction Manual

Introduction

General Description

Thank you very much for your purchase of the MUTEC REF10, respectively the REF10 SE120 an audiophile 10 MHz reference master clock generator.

The REF10 is an audiophile reference master clock generating 10 MHz signals with ultra-low phase noise (i.e. jitter) to significantly improve digital playback systems. As the conductor of your digital audio orchestra at home, the REF10 will inspire you with unheard-of clarity, graceful dynamics, and pure music. It is also the most flexible, most compatible 10 MHz clock on the market allowing you to spend less time worrying about integration and leaving you with more hours to enjoy blissful playback.

In contrast to so-called »atomic clocks«, clocks based on a rubidium or cesium normal, the REF10 as well as the REF10 SE120 are engineered around MUTEC’s handcrafted, oven-controlled oscillators (OCXO) made in Germany, featuring significantly higher clock stability in the time domain relevant for audiophile digital audio performance. Newly developed ultra-low noise clock distribution and amplification circuits based on sub-1 Hz optimized, lowest noise voltage sources transfer the reference signal to the unit’s eight outputs with virtually no losses.

As a result and unlike any other currently available reference generator the REF10 and REF10 SE120 fulfill both of the critical requirements for an extraordinary audiophile reference master clock:

• Lowest possible phase noise for unmatched audio
• Highest clock precision for most accurate synchronization

The REF10 SE120 is a special version of the REF10 that we have further enhanced in terms of signal performance. It outperforms the original REF10 in this regard considerably. A clearly measurable advantage is the result of a special feature of the REF10 SE120: its much more elaborately manufactured and selected OCXO. This oscillator is selected according to the strictest standards in test procedures lasting many hours with help of exceptionally precise and expensive measuring technology. The use of such an outstanding oscillator is responsible for the fact that the REF10 SE120 currently delivers – to our knowledge – the lowest phase noise, respectively jitter values in the industry. This outstanding technical performance has a noticeable impact on the sonic audiophile result. Precision, transparency, spatiality and dynamics of the musical presentation reach an unprecedented level and will amaze you

Installation

Shipping Contents
Your REF10, respectively REF10 SE120 was packaged carefully.
Nevertheless we recommend checking the contents directly after opening the package:

• 1 x REF10 or REF10 SE120
• 1 x Power cable
• 1 x Manual

In the unexpected event that there are any visible damages or missing items, please refer to the chapter »Safety Instructions« and »Warranty Regulations« for further details

Placing the Device

The unit should be set up as closely as possible to the devices to which it will be connected to avoid excessive cable lengths. The four custom-designed case feet include a rubber ring protecting the ground’s surface from being damaged and reducing any structure-borne vibrations interfering with the unit. It is recommended to keep the device away from vibrating or mechanically moving devices in close proximity.

The device can be mounted into a standard 19“ rack and will require 2U (rack units). Therefore, we offer an optional rack mounting kit called MW-07/19. This includes two rack brackets which need to be screwed to each side of the device‘s case. Before mounting the device into a 19“ rack, please unscrew the four rubber feet with a suitable screwdriver. Install the device so that 1U of rack space is left open both above and below the device to allow for sufficient ventilation! For extra secure installation we further recommend an additional rack mounting plate that will prevent any long-term mechanical deformation of the enclosure.

Attention
Before installing the unit the section Safety Instructions located at the beginning of this manual should be read carefully! Never expose the device and accessories to rain, moisture, direct sunlight, or excessive heat produced by radiators, heaters, or spot lights! Sufficient air circulation in the proximity of the device must be ensured!

Interface Connections
There are two standards with respect to interfaces and cable termination for 10 MHz reference signals:

• 50 Ω impedance termination
  This standard can commonly be found among units by Japanese Hi-Fi manufacturers, and for measurement devices in laboratory applications.

• 75 Ω impedance termination
  This termination is more common for devices used in recording, mixing and broadcast studio applications.

For audiophile Hi-Fi and high-end consumer audio applications both standards are currently in use by different manufacturers.
For this reason, the REF10, respectively REF10 SE120 provides clock outputs with both 50 and 75 Ω termination that can be used simultaneously.

Transferring clock signals with 50 Ω termination is typically done with coaxial cables according to the RG-58/U standard. However, we recommend using cables manufactured to the RG-400/U or CLF200/HDF200 standards, because they are double-shielded and offer reduced attenuation in contrast to the RG-58/U norm. Cables specified as CLF200/HDF200 further feature a stronger inner copper conductor.

For clock signals with 75 Ω termination it is common to use coaxial cables specified by the RG-59/U and RG-598/U as well as RG-216/U sstandards.

A wide range of coaxial cables with BNC connectors and the appropriate termination by specialized manufacturers are available at Hi-Fi retailers. Depending on their price range they are manufactured using premium materials and will have superior transfer characteristics than the aforementioned standard cables.

All interfaces of the devices in a given setup need to be properly connected with each other. Always ensure that the clock output of the REF10, respectively REF10 SE120 are connected to an appropriate input of the receiving device. Make sure that the clock input of the receiving device has the correct internal impedance termination. This internal termination can sometimes be adjusted via an external switch on the device or via a software setting. We recommend double-checking the operating manual of any device that you are planning the REF10, respectively REF10 SE120 to be connected to. A mismatched termination of the system will cause losses in signal quality and clock precision!

We further recommend keeping the cable lengths as short as possible to minimize signal losses and interference. Cables at 0.5 m, 1 m, or a maximum of 2 m length are ideal. The longer the cable needs to be, the higher the quality should be to avoid excessive losses!

Useage of so-called BNC tee adapters
BNC tee adapters are often used to daisy-chain clock signals between several devices. Usually this is necessary if the clock master does not provide a sufficient number of clock outputs. Since the REF10, respectively REF10 SE120 generates exceptionally low phase noise, i.e. highest quality signals, any additional elements in the signal path can have an attenuating effect that negatively affects the crucial slew rate of the signal. Consequently and considering that the REF10, respectively REF10 SE120 provides a total of eight clock outputs we advise against daisy-chaining 10 MHz clock signals.

Any device that is supposed to be clocked by the REF10, respectively REF10 SE120 and benefit from its audiophile performance must be connected to a dedicated clock output!

Control Elements and Terminals (equal for REF10 and REF10 SE120)

Front Panel

1. »POWER«
   This red LED illuminates when the device has been powered up. First engage the rear panel power switch next to the mains terminal. Always ensure the appropriate choice of line voltage
   »115 V / 230 V«! Then, depress the front panel power switch and the red LED will light up.

2. »OUTPUT SELECT«
   This combined push button rotary encoder is used to select the individual outputs and to disengage or re-engage them.

3. »LEDs 1–8«
   These eight white LEDs represent the eight rear panel clock outputs and reflect if the respective output has been turned on or off. An illuminated LED means the output is active, i.e on.

4. »OSCILLATOR«
   This blue LED reflects the status of the oscillator heat-up process. Upon powering the device up this LED will be flashing until the oscillator has reached its correct operating temperature. Once the temperature has been established, the LED will be permanently lit.

Rear Panel

1. »50 Ω, Outputs 1 –2«
   These two clock outputs are equipped with a 50 Ω termination. Use only BNC cables with the appropriate 50 Ω impedance with these outputs.

2. »75 Ω, Outputs 3 –8«
   These six clock outputs are equipped with a 75 Ω termination. Use only BNC cables with the appropriate 75 Ω impedance with these outputs.

3. »110/120 V & 220/240 V«
   This is is the line voltage selector that also serves as the holder for the mains fuse.
   Attention
   It is imperative to make sure the proper line voltage has been selected prior to powering up the device for the first time!
   Information on how to change the line voltage can be found in the chapter “Changing the line voltage” on page 15 in the appendix.

4. Mains Connector
   Connect the supplied IEC power cable here. Make sure that the power switch is turned off before connecting the device to your power source.

5. Mains Power Switch
   The mains power switch engages the power supply for the device. Do not turn the unit on before completing the wiring and installation, particularly with respect to the choice of line voltage according to you country’s power grid. Please make sure to read the safety instructions at the beginning of this manual!

Operation

General System Operation

Operating the REF10, respectively REF10 SE120 is very straight-forward! Apart from the two power switches there is only a single push button rotary encoder (»OUTPUT SELECT«) used to individually turn the eight outputs on or off. Per factory default all outputs are active upon powering up the device for the first time, so all eight white front panel LEDs will light up accordingly!

Selecting and toggling the outputs
The front panel encoder’s action is stepped and each step will evoke a new setting. The push button function of the encoder is used to toggle features.

Rotate the encoder by one step to select an output and the first LED will start flashing. Turning the encoder by another step now will cause the next LED to flash while the previous one returns to a steady light. Thus, it is only possible to select one output at a time.

As long as an LED is flashing, the respective output can be toggled with a push of the encoder. When the LED is on, the output is active. When the LED is off, the output has been disengaged. Any setting will have immediate effect – it is not necessary to take any further actions.

The last setting of the REF10, respectively REF10 SE120 will be stored and preserved after the the device has been powered down.

Recommendations for REF10 and REF10 SE120

To ensure a long-lasting performance with optimum clock signal quality that will best enhance your connected devices we would like to share a few recommendations for using the REF10, respectively REF10 SE120.

• First customers have told us that for best sound performance of the connected devices it is useful to let the REF10, respectively REF10 SE120 burn-in for at least 14 days. Thus, we recommend to leave the unit switched on for that period of time.

• Prior to enjoying an in-depth listening session we recommend pre-heating the REF10, respectively REF10 SE120 for about 20-30 minutes. While the heater generally reaches its operating temperature in about one minute, the entire oscillator section takes longer to fully warm up. To ensure optimal performance and highest frequency stability, you should grant your REF10, respectively REF10 SE120 this additional warm-up time.

• Keeping the REF10, respectively REF10 SE120 permanently powered up is generally not required as long as you observe the extended warm-up period described above. We do however advise against power cycling the unit in short, repeated intervals!

• he REF10, respectively REF10 SE120 should always be placed away from mechanically vibrating devices (such as turn tables). Although the unit’s case feet are equipped with isolating rubber rings, excessive structure-borne vibrations can nonetheless interfere with the oscillator and negatively affect the clock performance and signal quality.
  The REF10, respectively REF10 SE120 should furthermore not be placed in close proximity to devices emitting strong electromagnetic fields (such as fluorescent lamps). Even though the electronics of the unit are encapsulated in a steel enclosure these strong electric fields can interfere with the sensitive electronics and also negatively affect the signal quality.

• We generally recommend disengaging all clock outputs that are not used for your given setup to reduce potential interference as much as possible. Additionally, unused and disengaged outputs can be fitted with so-called BNC caps.
  These are available from various retailers and can be used regardless of the termination impedance of the REF10’s, respectively REF10 SE120’s outputs. The use of so-called BNC terminators is not necessary to protect the outputs.

Applications

Using the REF10 or REF10 SE120 With Other Products

This chapter serves to illustrate several possible applications for the REF10, respectively REF10 SE120 and will help you achieve the best possible sonic results. In general, both units can be used for the following applications:

• As an audiophile performance enhancement for compatible DACs, master clocks and audio re-clockers.
• As an ultra-low noise, high stability clock reference for the entire digital audio chain at home or in the studio.
• As an ideal high-end upgrade for MUTEC’s own MC3+, MC3+USB and iClock/iClock dp master clocks.
• To stabilize existing audio clock generators

To explain these applications it is important to understand that the REF10, respectively REF10 SE120 is a reference master clock exclusively generating highest quality 10 MHz clock signals. Compatible devices can use this ultra precise reference clock signal to perform their own signal processing with more accuracy and fewer errors, yielding a better sound quality. It is crucial to understand that these 10 MHz clock signals are entirely independent from the audio clock (typically 44.1 kHz up to 192 kHz) of the playback! As a consequence, the unit’s clock signal is not compatible with the common Word Clock audio clock that is also transmitted via 75 Ω BNC cables.

There are two possible routes to harness the superior clock precision of the REF10, respectively REF10 SE120 in your digital audio system:

• You have a DAC, network bridge, streamer or audio re-clocker with its own 10 MHz compatible input.
• You have an audio master clock that can take the 10 MHz clock from the REF 10 and convert it into standard a Word Clock audio clock to be distributed to other devices.

The simplest possible application for the REF 10, respectively REF10 SE120 would look like this:

Thanks to a total of eight clock outputs on the REF10, respectively REF10 SE120 any 10 MHz compatible device in a setup can and should receive its own dedicated clock supply. We strongly advise against daisy-chaining multiple devices using so-called BNC tee adapters (more about this on page 9).

Particularly the combination of the REF10 or REF10 SE120 with MUTEC’s own MC3+ and MC3+USB Smart Clocks offers exciting applications to achieve the best- possible quality enhancements by re-clocking digital music sources. To understand this scenario, please imagine the following setup as a starting point:

In this application example we have several digital sources on the left that are used to play back music via several digital interfaces (e.g. AES3, S/P-DIF or USB). The MUTEC MC3+ or MC3+USB act as audio re-clockers to enhance the music signal and remove jitter before passing the signal on to the DAC (d/a converter) and the loudspeakers. This is a simple closed system in which the audio clock rate is determined by the music source. All other devices following in the chain (audio re-clocker and DAC) will adapt to the sampling rate set by the source.

This particular system can be enhanced by the REF 10, respectively REF10 SE120 in up to three places, depending on how many of the digital devices offer a 10 MHz compatible input. In the best possible case, all of the digital sources (e.g. Blue-ray player, streamer, network bridge), the audio re-clocker and the DAC can receive their own and individual 10 MHz clock supply

It is helpful to understand that the hierarchy with respect to the audio clock (i.e. the sampling rate) of the system remains unchanged.
The 10 MHz signal from the REF10, respectively REF10 SE120 is strictly used to enhance the performance of the connected devices and does not make changes to the audio clock of the system. The sampling rate of the system is still determined by the music source, which is important to know when playing back playlists with mixed sampling rates.

Of course this application example is also conceivable without using an audio re-clocker between the digital sources and the DAC. In this case, the REF10, respectively REF10 SE120 can still yield a significant improvement in sound quality, as long as at least one of the other devices is equipped with a 10 MHz compatible clock input.

To help you getting started in the »10 MHz« universe we have put together a comprehensive list of currently available 10 MHz compatible devices.

Appendix

Changing the Line Voltage

Always unplug the mains cable before changing the line voltage fuse!

On the left hand side of the mains power module on the rear you will see two small triangles facing each other (see left arrow in picture above). The respective line voltage »110-120 V« or »220-240 V« is printed above the right triangle. If this setting should not be appropriate for your power grid, the fuse holder (see right arrow in picture above) needs to be pulled out, rotated by 180° around its own axis, and be put back in place. You should then see that the triangle now indicates the correct line voltage. It is easiest to remove the fuse holder by inserting a small flat screwdriver in the groove on the right side of the fuse holder to pull it outwards.

Make sure that the fuse holder is properly seated in its housing with its top flush to the power!
