INSTALLATION
Introduction
Congratulations on the purchase of the new M1 HPAP. This unit will give top quality performance when used
as a top quality headphone amplifier, delivering the best performance possible from any source.
It is also
designed to allow use as a single-input (two inputs, if the USB input
is included) preamplifier.
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 HPAP 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 quantity of power at all times, and it is important that it
is adequately ventilated. The M1 HPAP 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 HPAP is supplied with a standard IEC mains cable which plugs into the IEC socket at the back ofthe
unit
Output connections
RCA pre-outputs: Use good quality RCA phone audio cables (fully connected signal and ground), for optimum
signal transfer.
6.25mm 1 %"
Jack headphone outputs: Use good quality headphones for absolute optimum sound quality.
Use either Jack socket to connect a pair of headphones, or use both Jack sockets for two pairs, if required.
Please note: different headphone types will almost certainly have quite different output levels and possible
sonic characteristic differences when directly compared. This
is due to each headphone's individual design.
Volume control settings may vary appreciably, depending
on the headphone's sensitivity, original source
material recording levels, and user listening comfort level.
Input connections
LINE (RCA) inputs: Connect line level source to LINE input sockets. Use good quality RCA phono audio cables
(fully connected signal and ground) 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.

LINE inputs
OPERATION
These inputs accept LINE level (nominally anything between 0.03V-3V RMS) signals from any hi-fi source.
They may
be connected directly to the stereo outputs of a CD player, DVD, Tape, Minidisk, and TV or similar.
Signals from a normal turntable with moving coil or moving magnet cartridge, (and
no internal amplification), will
need a PHONO preamplifier connected before the
M1 HPAP.
Alternatively,
it may be used to add headphone output to an existing integrated or pre-power amplifier setup.
To do this, simply identify the LINE outputs from the integrated or preamplifier. These are used for TAPE
RECORDING, and usually labeled TAPE OUT, TAPE REC or similar. Simply connect these outputs to the
M1
HPAP LINE IN sockets. If you had anything originally connected to the TAPE OUT or REC OUT sockets,
reconnect it to the LINE OUT sockets
on the M1 HPAP. See LINE output section below.
To use a LINE input, move the input select switch
on the front panel to the desired LINE position.
USB input
To use the USB input, move the input select switch on the front panel to the USB position (up).
Plug
in one or two pairs of headphones and adjust the volume control for comfortable listening.
LINE output
The LINE OUT sockets pass on the LINE INPUT totally unaffected. They are in fact directly connected to the
LINE INPUT RCA sockets to allow reconnection of a recording device (if the
M1 HPAP is using the TAPE REC
output of
an Integrated/Pre-Amplifier).
Note: volume control has no effect on LINE OUT levels.
PRE output
The PRE OUT sockets give an output that is affected by volume control. They are in fact directly connected to
the output JACK sockets to allow connection of a power amplifier. This allows the
M1 HPAP to be used as a
preamplifier with one line, and one USB input. When used
as a preamplifier, any unused headphones should be
disconnected from the unit.
The USB input source may
be selected for the PRE OUT sockets by selecting USB on the front panel switch.
The
M1 HPAP is a self contained unit. Therefore it does not mute the speakers in a system (even if using the
unit as a preamplifier). If listening through headphones
on a system with speakers, please turn down the
speakers using the system volume control, or switch off the power amplifiers.
It is recommended in such a setup to switch on the power amplifiers AFTER switching on the HPAP, and to
switch off the power amplifiers BEFORE switching off the
M1 HPAP.
Computer settings for USB
A good quality USB A to B cable is required to connect the unit to the computer.
Plug the B (square) end into the socket
in the back of the unit, and the A (rectangle) end into a free USB socket
on the computer.
The computer should now detect the new hardware and install a generic driver automatically (No setup or driver
disk should
be required).
CD, MP3, WAV, AAC, FLAG, and all other audio file types p·layed on any software should now play through the
unit. This device has been designed to work with
PC Windows 98, ME, 2000, XP, Vista and 7, as well as Apple
Macintosh
OS X, Snow Leopard and later.
PC users-
Check the computer has picked up the device and
is currently using it by clicking: (most Windows
versions)
-Start
-Settings
-Control panel
-Sounds and Multimedia
-Audio
Check that "USB audio device" appears under
PREFERRED AUDIO DEVICE tab
A second mixer will now be available which will be
the default mixer whenever the unit is plugged in.
Use this mixer to select the source or adjust levels
if required.
Mac users-
Check the computer has picked up the device and
is currently using it by clicking: (MAC OS X)
-System preferences
-Hardware
-Sound
Check that "USB audio DAC" is selected under the
OUTPUT tab.
If the computer's warning sounds/chimes are to
played through the unit, make sure it
is selected
under the
SOUND EFFECTS tab too.
Note: USB may also
be selected as an output in
some individual programs.
Please note: This device is a high speed serial data processor, and by its nature, requires a very high volume of
USB band width. It will benefit greatly from being the only device connected on its USB 'bus'. Sharing the same
bus with otherdevices
may cause unwanted artifacts such as dropouts or temporary loss of signal.
This
espeC?ially applies to the use of the unit on a USB hub/splitteralongside other USB components

Problem
No power
No sound
Sound
is not precise, lacking in
bass and stereo image
Hum
No audio output, or too low
level output
No audio output from USB
input
Not detected when connected
to USB
Dropouts
in sound (USB input)
Probable Cause
Mains power supply is not fully inserted
into mains socket
Mains power supply lead
is not fully
inserted into rear socket
Wrong connections between input
sources and the unit
Headphone(s) connector plug not fully
pushed
in
Lead fault in headphones
Audio connector plug not fully pushed
in
Cable Fault
Unsuitable Cable
(e.g. cable grounds not connected)
Incorrect or missing connections
USB Driver not selected (PC or MAC)
USB Cable not connected
USB Driver not selected (PC or MAC)
USB Cable faulty
USB not working/enabled
on computer
Correct USB drivers not installed
(can happen particularly with factory-
preinstalled Windows operating
systems)
Shared USB port with another device
Computer busy with another application
Computer low
on resources
Remedy
Plug in securely
Check audio input lead
connections
Check plug
is inserted fully and
securely
Check phones
on Headphone
output
of a different unit
Insert plug securely
Check cable
is connected at both
ends.
N. B. some esoteric cables have
internal wiring intentionally
disconnected/modified. For best
results on all inputs analogue AND
digital, please use good quality
screened coax; signal and screen
directly connected both ends.
Check connections and make sure
they are secure.
See P.8
PC users or MAC users
section
Check connections and make sure
they are secure.
See P.8 PC users
or Mac users
section
Check and replace cable
Check USB port functions with
another device.
Please check with the computer
manufacturer. Enquire about USB
driver or update.
Avoid sharing the USB port with
other devices, if possible.
At times
an application (program)
may intervene, sometimes invisibly
e.g. a virus scanner. When this
happens, computer resources are
temporarily used
up, and playback
may suffer. This
is not a fault. Try
running fewer applications if
possible.
If none
of these actions affect a cure, please contact the dealer, or an authorised Musical Fidelity service agent.
Never open the case of the unit, as this will invalidate the guarantee.

Dear Fellow Music Lover,
Thank you for purchasing a Musical Fidelity product.
About thirty years ago, I started Musical Fidelity on my kitchen table. Finance was
supplied from my £500 limit on my credit card and $200 loaned to me by my
mother-in-law. Everything else came from my passion and commitment to making
the best hi-fi I knew how.
Three decades have gone by in a blink
of an eye. Musical Fidelity products may
look different now, and they are made in a small factory instead
of on my kitchen
table, but my passion and commitment to their quality remains undimmed.
At Musical Fidelity, we use every ounce
of our experience, knowledge and
understanding
of hi-fi to make sure that every product sounds fabulous, is a great
technical performer and,
of course, gives excellent value for monry.
We hope that your Musical Fidelity product brings you huge musical satisfaction.
Welcome to the Musical Fidelity family. Thank you again.
Kindest regards,
Antony Michaelson
Founder, Musical Fidelity Limited
