Edwards Audio MC2 User manual

User manual MC2
Thank you for purchasing an Edwards audio phono stage, with care over the
correct installation we are sure that it will give many years of pleasure.
CONNECTIONS
The main MC2 should be placed on a separate
shelf next to or near your Turntable. Connect
your turntables arm leads to the sockets marked
‘input’ observing Red for RIGHT and White/Black
for LEFT. If you have an additional Earth or
Ground cable attach this to the GND terminal
provided above the input sockets. Depending
on your systems grounding arrangements it may
or may not be necessary to connect this, so if
you can hear a hum through your speakers try
connecting/disconnecting this wire. Next connect
an additional pair of high quality RCA Phono
cables (not supplied) between the output sockets
and any available LINE input on your amplifier,
this is usually marked AUX. Next the Power supply
should be plugged in to any available AC outlet
near to your system then plug the Mini Din into the
socket marked DC on the rear of the MC2. Please
observe the polarity and do not force the plug into
the socket else damage may occur. To power ‘ON’
switch on the AC power supply at the wall, there is
no power switch on the phono stage itself.
LISTENING
At this point it may be a good idea to try playing
a record by selecting Aux on your amplifier (or
whatever input you used to plug the MC2 into) and
advancing the volume control slowly, hopefully
music will be heard. Assuming all is well, lift the
needle from the groove and check that there
are no hums or buzzes, if there are, experiment
with the position of the MC2 and or the ground
connection, it may well be that the quietest position
is not on a shelf at all. There are no hard and
fast rules as to where to best position the MC2,
basically the quieter it is the better it will sound,
all you should hear is a feint hiss, if this is on the
floor behind your equipment rack the so be it.
Don’t be worried about where it is, it’s position and
orientation will have no detrimental effect on the
MC2’s function or reliability.
FRONT PANEL LED
You can turn off the front panel LED indicator,
should you desire by removing the Blue jumper
(J1 on diagram 2) from the front of the PCB, This
can be accessed by removing the 4 screws on the
rear panel marked in red on diagram 1. and sliding
the PCB out backwards, see diagram 1.
MM – OPERATION
The factory default is the MC setting but if you
wish to use this with an MM or HOMC cartridge
this can be set by moving the 4 yellow jumpers
marked J3,J4,J5,J6 in diagram 2 to their alternate
positions. These jumpers can be accessed by
removing the four screws on the rear panel marked
in red on diagram 1, (excluding the GND terminal)
and sliding the PCB out backwards. There are no
user serviceable parts inside, so please do not be
tempted to play or modify any part of the MC2, this
will invalidate your guarantee.

WARP FILTER
There is a warp filter function which operates at a
very low frequency of around 7Hz. This frequency
was chosen as it is around the common arm/
cartridge resonant frequency and helps to remove
any excessive cone movements in your speakers
due to this as you play a record. It can be disabled
by moving 2 Green jumpers J14 & J15 on diagram
2 to the off positions
