Power
When power is applied, the STANDBY key
a
is used for
power control. The standby indicator
b
shows green when
the amplifier is operating and glows red when in standby
mode.
In regular use the preamplifier should be connected
permanently to the mains power supply. When left
unattended for a long period (holidays etc) it should be
disconnected from the AC supply.
Selecting an Input
Press the INPUT key •
1@
.
The current input number will be displayed.
Turn the ROTARy CONTROl • e to change to another
input.
Press the ROTARy CONTROl
• e to select the input.
After a short delay, the input will be selected.
Settings display
The display will indicate the input number selected and
whether the input is set for MM or MC operation.
The display will also indicate the gain setting in dB, the input
resistive load setting (IP R) and the input capacitive load
setting (IP C).
The bargraph display shows a graphic indication of the left
and right channel levels. This can assist with setting MC
gain.
MM/MC cartridge type selection
Each input can be set to be compatible with either Moving
Magnet or Moving Coil cartridges.
To change between MM and MC for the selected input -
Press the MM/MC key •
1)
.
Turn the ROTARy CONTROl •
e
to switch between Moving
Magnet and Moving Coil settings.
Press the ROTARy CONTROl • e to select a new setting.
After a short delay, the cartridge type will change and
the selection will be saved for this input.
MM/MC indicator
The MM/MC indicator will light yellow when an input is set
to Moving Magnet and green when set to Moving Coil.
When an input is selected or a setting is changed the
indicator will change to red briefly to indicate that the sound
is muted.
Cartridge matching
Moving coil cartridges
If you have connected a moving coil cartridge to one or
more of the inputs, you should now refer to the ‘Configuring
MC Inputs’ section on the next page to configure those
input(s).
Moving magnet cartridges
For inputs set for moving magnet cartridges, the gain,
resistive load and capacitive load settings are pre-optimised
to standard values that best match this type of cartridge.
The GAIN, RES (resistance load), and CAP (capacitance load)
keys are therefore disabled and the indicators will not light.
Warp filter
The warp filter will assist in removing very low frequency
information caused by warps in the vinyl. In a high quality
record playing system these large amplitude signals may
overload a preamplifier or cause large bass unit excursions
for the loudspeakers.
Press the WARP key • 1! to switch in the warp filter.
The WARP indicator will light and ‘FLTR’ will be
displayed.
Low frequency signals caused by warps will be reduced.
Press again to cancel the warp filter. •
