They select if signal will be present on the
balanced outputs (XLR connectors), or on
the unbalanced outputs (¼-inch, 2-conductor
monaural jacks). The nominal level of the
balanced outputs is +4dBu, unbalanced is
–10dBv.
Level monitoring has been improved by
going to 5-segment level meters, instead
of the original signal present and clipping
LEDs. The meter ballistics are designed
to give a combination of VU and peak
performance.
We hope you like the improvements!
Installation
Mounting
The Mic-PreEminence is rack-mountable,
requiring one 1.75-inch (4.5cm) rack space.
It weighs a bit over four pounds (1.9kg),
and operates on AC mains power of either
nominal 115Vac or 230Vac.
Locating the Unit
It is a good idea to keep the
Mic-PreEminence physically separated
from other electronic devices that produce
electrical fields. As a high gain device,
hum and noise pickup is possible through
the chassis and associated cabling. Locating
the unit away from power amplifiers, power
transformers, lighting controls, etc., will
help to avoid pickup of unwanted signals.
If the Mic-PreEminence is mounted in a
rack, be sure that sonic “garbage” is not
being picked up from nearby equipment.
Connecting the Unit to Power
The Mic-PreEminence may be operated
from mains power of either nominal 115Vac
or 230Vac, 50/60Hz. Units shipped to North
America are factory selected for 115V
operation and are supplied with a 0.5A 3AG
fuse and a power cord. Units shipped out-
side North America are factory selected for
230V operation and are supplied with a
0.25A 5x20mm fuse. No power cord is
supplied with those units. Your dealer or
distributor will provide an AC mains cord.
Before connecting the Mic-PreEminence
to power, determine the actual line voltage
and check to see that the voltage selector
switch (located on the back panel of the
unit) is set to the appropriate voltage.
Please note that an incorrect setting could
seriously damage the unit. Should it be
necessary to change the voltage selection,
ensure that the correct fuse value is used:
0.5A for 115V, 0.25A for 230V.
The Mic-PreEminence uses an IEC
standard connector to mate with the AC
mains cord. The wire colors in the AC mains
cord should conform to the internationally
recognized CEE color code and must be
wired accordingly:

Signal Connections
All signal connections on the
Mic-PreEminence are made via 3-pin,
XLR-type male and female connectors, and
¼-inch, 2-conductor monaural jacks stan-
dard to the audio industry. The microphone
input connectors are female, the balanced
