Introduction
Congratulations on the purchase of the new M1 DAC. This unit will give top quality performance when used as
a top quality digital to analogue converter, delivering the best performance possible from any digital source. It is
designed to upgrade CD players, DAB tuners, Minidisk, and any other source providing digital stereo PCM
outputs.
Cleaning
Before cleaning the unit, switch off power at the mains switch and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist cloth. Using solvents, white spirit or thinners is not
advised, as they could damage the surface finish.
Installation
Position the M1 DAC 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 DAC 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.
Please note: Musical Fidelity currently do not make any interconnecting cables, nor do we endorse any
particular manufacturer's cables. If necessary, please refer the dealer who can advise on quality cables for any
particular setup.
Power Connections
The M1 DAC is supplied with a standard IEC mains cable which plugs into the IEC socket at the back of the unit
Audio output connections
RCA audio outputs: Use good quality RCA phono audio cables (fully connected signal and ground), for
optimum signal transfer.
XLR audio outputs: Use good quality XLR audio cables (fully connected hot and cold signals and ground), for
absolute optimum signal transfer.
Digital input connections
COAXIAL input: Connect RCA digital source to digital input RCA socket. 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.
OPTICAL input: Connect optical digital source to optical input socket. Use a good quality "Toslink" cable, for
optimum signal transfer.
USB input: Connect computer or similar USB "host" source to USB input socket. Use a good quality USB 1.1 or
2.0 "A to B" type cable, for optimum signal transfer.
If connecting to Home Theatre Processor, TV or DVD, or similar Home Theatre sources, it may be
necessary to change the digital output of that source to "16 bit stereo PCM", or similar, which is the format the
M1 DAC will understand. Please refer to the source's manual for information on how to do this.
This is because the M1 DAC does not recognise the information in multichannel (e.g. 5.1 surround sound)
digital audio streams.
