OVERVIEW
We believe
the best way to step up a Moving Coil
cartridge is with a wide bandwidth
transformer. The reason we like this
approach is two fold. One is that it's
a passive device and therefor
noiseless. Two, is that makes the
cartridge sound better with improved
dimensionality, weight, and top end
resolution.
This device
is used only when your phono stage
doesn't have MC (moving coil) inputs
which is often the case with tube
phono stages.
The ZMC
features an adjustable cartridge
loading knob on the front of the unit.
To use it, slowly turn the knob while
the record is playing until the volume
stops increasing. At that point
you cartridge is perfectly loaded.
You can of
course use this knob on the fly or
revisit the setting at any time.
It can be handy to sometimes under
damp the cartridge to give more air in
the top end, or over damp the
cartridge to tame a bright sounding
record. You do that by simply turning
the knob slightly down or slightly up
from the ideal setting.
We offer
three types of transformers shown
below. With our own phono stage (model
ZP3) the most popular choice for a
step up is the ZMC1. The higher
ratio works well with the 42dB of gain
from our phono stage and mates best
with most cartridges.
|
ZMC1
|
For low
output MC cartridges
|
1:20 ratio for
use with 3~25 ohm
cartridges.
|
|
ZMC2
|
For high
output MC cartridges
|
1:10 ratio for
use with 3~100 ohm
cartridges.
|
|
ZMC3
|
For high
impedance MC cartridges
|
1:12 ratio for
use with 25~100 ohm
cartridges.
|
The
high bandwidth and very low phase
shift ensures excellent transient
response. Mumetal can
for magnetic shielding is standard.
Typical
response is 10Hz ~ 100kHz.
OPERATION
The ZMC connects between your turntable
and phono stage. There is a standard
ground lug on the rear of the ZMC. In
addition, there is also an IEC connector
for those rare custom systems that wish
to place an earth ground at the source.
Since the best way to obtain an earth
ground is ta wall outlet, you can
simply use a standard grounded power
cord between the ZMC and wall outlet.
In regular systems using a power
cord to effect an earth ground for the
ZMC is not recommended.
