WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
The lightning flash with arrowhead symbol, within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying
the appliance.
CAUTION: Changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to

DO NOT attempt to lift or move the Conductor-LP without
adequate assistance. Failure to follow the procedures included
in this section may result in personal injuries and/or product
damage.
DO NOT attempt to lift the Conductor-LP while bending at the
waist. When lifting, stand as straight as possible using the leg
muscles to lift.
When unpacking the Conductor-LP:
DO save all packing materials for possible future shipping needs.
DO inspect the Conductor-LP for signs of damage during shipment.
If damage is discovered, contact an authorized Clef Audio dealer for
assistance making appropriate claims.
Unpacking
Caution!
Warning!
Position the Conductor-LP on a stable, horizontal surface where
there is no risk of it being knocked, or subjected to vibration such as
from loudspeakers.
Conductor-LP 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.

When shipped, the Conductor-LP is configured for 220-230V AC
power operation at 50Hz. Before operating the Conductor-LP make
sure the AC mains connector label indicates the correct operating
voltage for the current location.
The Conductor-LP should be unplugged during lightning storms
and extended periods of non-use. Otherwise, it is designed for
continuous operation. For best performance, make sure power is
connected to the AC mains connector at all times. During normal
operation, do not use the power switch (on the rear panel) to power
off the Conductor-LP. Instead, use the on/off button to place the
Conductor-LP into standby.

Operating States
The Conductor-LP has a very accurate RIAA equalization curve. This
curve is accurate to better than 1/10 dB over 10 octaves.
The accuracy of this curve does not vary with an adjustment change
of gain or cartridge loading.
Conductor-LP features gain adjustable from between 40dB and
76dB; a range sufficient to allow successful operation of not only
high output moving magnet cartridges, but also the lowest output
moving coil cartridges without the use of an auxiliary step-up
transformer.
Dual mono design topology. This gives the better isolation between
channels. Soundstage imaging is improved, offering true
soundstage width and depth. Instrument placement and layering
are more accurate.

Moving Magnet cartridge need to select capacitance. It will be
impossible to give suggestions for correct capacitance with any
given cartridge, due to the huge variation in capacitance on the
cables. The optimal value is selected by listening.
There are five Capacitive loading switches with values of 100pf,
220pf, 330pf, 430pf and 550pf.
The correct value is that which gives the best overall tonal balance.
Typically if the cartridge sounds too bright more capacitive loading
will be required. The typical Moving Magnet cartridge has a fairly
predictable output.
The Conductor-LP gain in moving magnet is fixed at 42dB and
Resistive loading is fixed at 47k-ohm
Moving coil cartridges are the typical cartridges of choice for the
serious Audiophile and generally the lower output moving coil
cartridges are preferred. The Conductor-LP may be used with even
lower output cartridges without an auxiliary step-up transformer.
To operate the Moving Coil pre-amp, you need to select Moving
Coil (MC) "On". In addition you will need to attach the turntables
phono cartridge to the Conductor-LP Moving Coil input.
Your next task is going to be to set gain and Resistive Loading.
The available gain settings are 52 dB, 62 dB, & 72 dB.
There are five Resistive loading switches with values of 33ohm
100ohm, 470ohm, 1k-ohm and 47k-ohm.
