User manual MC1
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.
INSTALLATION
The main MC1 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 between the output sockets and any
available LINE input on your amplifier, this is
usually marked AUX. 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 MC1. 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
Having successfully connected the MC1 to your
system you can now try playing a record. Select
Aux on your amplifier (or whatever input you used
to plug the MC1 into) and slowly advance the
volume control, hopefully music will be heard.
Assuming all is well, lift the needle from the groove
and listen to check that there are no hums or
buzzes, if there are, experiment with the position of
the MC1 and or the ground connection, it may well
be that the quietest position is not on a shelf at all.
CONNECTIONS
INSTALLATION
There are no hard and fast rules as to where to
best position the MC1, 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 MC1’s function or
reliability.
FRONT PANEL LED
Should you want to, you can turn off the front
panel LED indicator. This is done by moving the
Blue jumper shown on as J1 on diagram 2. This is
located near the LED at the front of the PCB. This
can be accessed by removing the 4 screws on the
rear panel marked in black on diagram 1. and Slid
ing the PCB out backwards, see diagram 1.
MM OPERATION
The factory default setting for the MC1 is MC
however 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, and J6 in
diagram 2 to their alternate positions. These
jumpers can be accessed by removing the four
screws on the rear panel marked in black on
diagram (excluding the GND terminal) and sliding
the PCB out backwards.
