Musical Fidelity M1-SDAC Instruction Manual

Instructions for use

Thank you for purchasing the Musical Fidelity M1 SDAC.

The M1 SDAC consists of a 32 bit DAC and a sample rate converter which asynchronously up-samples all incoming data rates to 192 kHz. This moves the digital artefacts to well outside the audio band, allowing easy removal without detriment to the top end of the audio band. Our well tuned filtering circuit gives immeasurably small jitter, noise and distortion artefacts allowing astounding imaging, detail and transparency, to deliver all music types exactly as the artist originally intended. This new design now takes into account different sampling frequencies with the upper audio bandwidth now extending to 90 kHz for 192 kHz natively sampled input signals.

The M1 SDAC fully asynchronous USB input copes with files up to 24-bit 192 kHz sample rate input. This takes full advantage of the higher quality recordings now available. It works with personal computers running Microsoft Windows®, Linux and Apple® OS.

An aptX® capable Bluetooth A2DP receiver has been included. aptX® is a high quality Bluetooth link. It features full bandwidth sound, for wireless connection to Bluetooth-capable products, such as mobile phones, computers, etc. The Bluetooth receiver is also backward-compatible with non-aptX® Bluetooth devices.

M1 SDAC has been carefully designed to be partnered with other M1, M3 and M6 products. It also matches well with M8 and M1 series products. Using any of these combinations will yield one of the best high-fidelity systems available at any price.

Used 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.

INSTALLATION

Introduction

Congratulations on the purchase of the new M1 SDAC. This unit will deliver the ultimate performance possible from any digital source. It is designed to upgrade CD players, TVs, set-top-boxes, DAB tuners, and any other source providing a variety of digital outputs.

Installation

Position the M1 SDAC on a stable, horizontal surface where there is no risk of it being knocked, or subjected to vibration such as from loudspeakers.

Important note: In normal operation, the unit dissipates a small quantity of power at all times, and it is important that it is adequately ventilated. The M1 SDAC 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 M1 SDAC is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the unit.

Audio input connections

RCA audio inputs AUX 1, AUX 2: Use good quality shielded RCA phono audio cables (fully connected at both ends - signal and ground), for optimum signal transfer.

Audio output connections

RCA audio outputs: Use good quality shielded RCA phono audio cables (fully connected at both ends - signal and ground), for optimum signal transfer.

HEADPHONES output: Use good quality headphones for private listening.

Digital input connections

COAXIAL inputs: Connect RCA digital source to digital input RCA sockets 1, 2 or both. Use a good quality fully connected (signal and ground) coaxial digital cable, for optimum signal transfer.

AES BALANCED input: Connect AES/EBU digital source to balanced digital input XLR socket. Use a good quality balanced DIGITAL cable, for optimum signal transfer. Recommended wiring is given on P.7

OPTICAL input: Connect optical digital source to optical input socket. Use a good quality “Toslink” cable, for optimum signal transfer.

Note: If connecting to Home Theatre Processor, TV or DVD, Blue-Ray, or similar Home Theatre digital sources, it may be necessary to change the digital output of the source to “16 bit stereo PCM”, or similar, which is the format the M1 SDAC will understand. Please refer to the source’s manual for information on how to do this. The M1 SDAC does not recognise the information in multichannel (surround sound) digital audio streams.

USB input: Connect computer or similar USB “host” source to USB input socket. Use a good quality USB 2.0 “A to B” type cable (not supplied), for optimum signal transfer. Try to keep USB cable length to a minimum for best reliability. The USB 2.0 standard maximum for a single cable is 5M, after which repeaters (normally mainspowered USB hubs) are required. We do however; recommend avoiding such a setup if at all possible and keeping the USB lead length to the absolute minimum possible for the setup.

Digital output connections

COAXIAL output: Connect RCA digital receiver or digital recording device to digital output RCA socket. Use a good quality fully connected (signal and ground) coaxial digital cable, for optimum signal transfer.

OPTICAL output: Connect optical digital receiver or digital recording device to digital output optical socket. Use a good quality “Toslink” cable, for optimum signal transfer.

Trigger Connections

Trigger input: Connect system triggering device output to this socket. Use good quality 3.5mm mono jack cable. Unit accepts 4.5V-15V DC triggering, either polarity.

Trigger output: Connect further devices in the system to be triggered into this socket. Use good quality 3.5mm mono jack cable. Unit passes on +12V DC at up to 60mA, for further devices.

Interconnects

Please note: Musical Fidelity currently do not make any interconnecting cables other than those supplied with the unit. Musical Fidelity does not endorse any other manufacturer’s cables.

If necessary, please refer to the dealer who can advise on quality cables for any particular setup.

DIGITAL OUTPUTS

Digital Outputs and Analogue to Digital Conversion.

ANALOGUE inputs are converted to digital internally by an analogue to digital converter. This allows the passing on of the selected ANALOGUE input signals to another DAC, processor, or recording unit digitally. The unit may therefore be used as an analogue to digital converter, passing on the ANALOGUE as well as DIGITAL input signal to another DAC, processor, or recording unit digitally.

The Digital output sockets all pass the DIGITAL input signal from digital optical/coaxial SPDIF or USB inputs at the same sample rate as it comes into the DAC. This means the digital outputs are not up sampled or reprocessed in any way.

The level of the digital outputs is not affected by the volume control.

The Bluetooth digital output is also available when selected, and is output at 96 kHz.

The USB digital output is also available when selected, and is output at native (original input) rate.

N. B. M1 S-DAC USB socket functions as digital input ONLY. No digital audio output signals are available from the USB socket.

Note: The SPDIF coaxial and AES (XLR) outputs are capable of up to 192 kHz 24 bit signals.

- The optical output however can only output signals up to 96 kHz. If input signal greater than 96 kHz is present, there will be no output from the optical output.

BLUETOOTH

The M1 SDAC features a Bluetooth A2DP audio input (receiver circuit). This can be used to receive Bluetooth transmissions from other Bluetooth Audio (A2DP) enabled devices such as mobile phones, laptop computers or similar Bluetooth enabled sources. If the connecting device

supports aptX®, the M1 SDAC will use it.

Bluetooth is a digital “radio” link and as such requires an external antenna to function. This antenna is supplied with the M1 SDAC. Consult the reseller/dealer if the antenna is missing.

BLUETOOTH antenna

M1 SDAC is housed in a top quality metal enclosure and therefore requires an external antenna for Bluetooth operation. Bluetooth is unlikely to work at all without the antenna attached!

The Bluetooth antenna should either be attached directly to the socket on the back of the unit. For better positioning flexibility, the antenna may be attached to its magnetic base which, is then attached to the antenna socket on the back of the unit.

When positioning the antenna, ensure it is away from potential sources of interference, and in full, plain view from across the room.

When making connections, please ensure the nuts are tightened to “finger-tight” and as such be secure. It is neither necessary nor recommended to use tools to tighten them any further!

BLUETOOTH device setup

To create a Bluetooth link it is necessary to “pair” and then “connect” the Bluetooth device(s) to the M1 SDAC.

This needs to be done every time a new device is introduced to the M1 SDAC.

The M1 SDAC stores information for up to 16 Bluetooth devices.

The M1 SDAC must be turned on; with blue POWER LED and display lit (it is not actually necessary to switch to Bluetooth input at this point, but it is easier to see when a valid link is established). The display will show no link. This means that the unit does not yet recognize any Bluetooth device in the vicinity.

BLUETOOTH

No Link

Please consult and follow the device (phone, etc) manual instructions for pairing.

You do not need to do anything on the M1 SDAC other than ensure it is ON.

If the DAC is not listed, try refreshing the list in the Bluetooth device, and check that the M1 SDAC is on (i.e. not in standby). Also check antenna is fitted; positioned away from potential sources of interference, and in full, plain view from across the room.

“Pair” (see device user manual for more details) with the “Musical Fidelity M1 SDAC” that should appear in the device’s Bluetooth list.

N.B. If asked for a password, please enter “1234” on the phone. This password is not changeable.

“Connect” (see device user manual for more details) with the “Musical Fidelity M1 SDAC” that should appear in the device’s Bluetooth list.

The device should then be “connected”. Successful connection is indicated by the word “Linked” as shown in the example below.

BLUETOOTH

44.1kHz > 192kHz

BLUETOOTH input

To use the BLUETOOTH input, press the BLUETOOTH input select button on the front panel, or remote control.

The incoming sample rate will be displayed if a valid digital signal is present.

BLUETOOTH

44.1kHz > 192kHz

Issue 4

Page 14 of 47

BLUETOOTH

aptX® audio (automatic)

If aptX is available on the connecting device, the M1 SDAC will automatically implement it for best audio quality.

To check if the connecting device supports aptX® please consult the device manuals/support. No user intervention on the M1 SDAC is possible and the setting is entirely automatic.

BLUETOOTH aptX 44.1kHz > 192kHz

The Bluetooth input is capable of accepting up to 16 bit 48 kHz PCM stereo data streams. The incoming data sample rate is accurately displayed on screen for reference.

Caution: If changing the Bluetooth link sample frequency from the transmitting device, e.g. computer, it is highly recommended to first disconnect/unpair the two Bluetooth devices before making the changes. Once the change has been made, simply reconnect/pair the two devices and carry on using as normal.

Disconnecting Bluetooth device(s)

To disconnect the M1 SDAC from the Bluetooth device press and hold the Bluetooth button Until the display shows

Forget all devs?

Confirm: OK

to cancel disconnection press any button or to continue with disconnecting press OK or press volume control in.

All devs removed

The M1 SDAC will prompt if the device is to be “Forgotten” or not. This is best used to forget devices that are not likely to be used again with the M1 SDAC. Up to 16 devices can be remembered so there is plenty of space for different devices under normal use.

Disconnect Link?

Confirm: OK

Press OK or volume knob to disconnect the link, any other key to cancel forgetting device (i.e. remember it). Forgetting the device briefly shows

Now disconnected

before returning to the Bluetooth input screen.
