The Amulet M Phantom
The
Amulet M Phantom
™ has new features as well
as the ability to be powered via phantom power. To
access these new features, unplug the keyed
Connector Plug
on the side of the preamp, then
remove the two screws on the sides of the preamp
and remove the lid. Here you will find the new
Gain
Trimmer
and
Phase Switch
.
The
Gain Trimmer
allows you to vary the overall
gain of the preamp plus and minus 14dB. This allows
you to set the output to
precisely match your
amplifier or signal chain,
and also enables you to
match output levels
between multiple instruments. This trimmer, combined with the Trim Control
located between the two transducer inputs (see P.7 of your
Amulet M User
Guide
for more info) gives a wide range of customizable adjustment.
The
Gain Trimmer
can be adjusted with a small flat-bladed screwdriver or
a #1 size Phillips head screwdriver. When this
Gain Trimmer
is set to the
center of its rotation, the output is the same as a standard Amulet M
system. The gain increases as the trimmer is rotated clockwise, and
decreases with counterclockwise rotation. Be careful not to force the trimmer past the built in
mechanical stops at each end of the rotation.
The
Phase Switch
is an internal slide switch that allows you to invert the
phase of your signal, so you can perfectly match any additional pickups you
might use with your instrument in a multi-system setup. This can also be used
to help to increase gain before feedback in difficult monitoring situations.
Make sure when setting the
Phase Switch
that it is set completely to one side
or the other
. If the switch is set in the middle, then there will be no output from
the preamp.
When the switch is set to the Down position (towards the endpin
jack) the output is in-phase, the same as a standard Amulet M system. Setting
the switch in the Up position (towards the transducer input jacks) will set the
preamp output out-of-phase.
The small
EXT Jack
on the side of the preamp is
where the controls for the M-V volume control or M-VT
volume and tone controls are connected. If you are
using the system with no controls
, you must insert the special Connector
Plug in this jack, or else there will be no sound from the system
. (NOTE :
The Connector Plug and M-V/M-VT control cable that connects to the EXT
Jack has a keyed design so that it only plugs in correctly with the plug oriented
in ONE DIRECTION. If you look at the side of the small black plugs on the
connector cable, you will see a small ridge on either side of the plug, closer to
one side than the other. If you look closely at the connector (either the EXT
jack or the connector on the soundhole thumbwheel controls) that it plugs into,
you’ll see a slot cut into each side, that will mate with the ridges on the connector, but ONLY WHEN IT
IS PLUGGED IN CORRECTLY. This is called a polarized connector, and it ensures that all of the cable
wires get hooked up correctly during installation. Make sure the two are lined up correctly, and don’t try
to force the plug in. If it won’t go, this would be the probable reason!
