LOC REAR PANEL
(1) INPUTS:
Bal Phono Input 1 / MM Conventional 3-pin
female XLR input connectors for use with
differential-balanced phono cartridges. Can also
be used with certain line-level sources.
Standard input load resistance is 47,000 ohms.
This resistance can be changed by the user to
facilitate different phono cartridge load
requirements. See phono preamp PCB
illustration on page 7.
Standard input load capacitance is 470 pF. This
capacitance can be changed by the user if
necessary, but should not be lower than 270pF.
XLR pin 2 is positive polarity. XLR pin 3 is
negative polarity. Connector contacts are
Neutrik gold plated. It is suggested that XLR
cable connectors used with the LOCi employ
identical plating.
Bal Phono Input 2 /MC, Conventional 3-pin
female XLR input connectors for use with all
standard phono cartridges. Can also be used
with certain line-level sources. Inputs 2 and 3
connect to an input transformer, the Lundahl
LL9226.
Phono In 3/MC RCA input. To use the RCA input
connections, select “MC OUT” on the front panel
Use your cartridge manufacturers recommended
R/C loading. The cartridge loading can be
modified by changing resistors and capacitors.
See illustration on page 13.
(2) PHONO PRE DIR OUT
Buffered Direct output from the pre amp card.
Post polarity and mono switching. This is the
same signal fed into the compensation and filter
circuits.
(3) PHONO PRE TRIM OUT
Adjustable, buffered signal derived from the
Direct out.
(4) UNBAL EQ OUT PRE TRIM
Post filter and compensation circuit unbalanced
signal. Available in both RCA and XLR
connections. Output RCA connections are
independent of input switching.
(5) BAL EQ OUT POST TRIM
Balanced output from the compensation and
filter circuits.
(6) EARTH/AUDIO GROUND JUMPER STRAP
A barrier terminal which ties earth ground to
audio ground. If ground “hum” loops are
experienced when using the LOCi, removing this
jumper may help. Using this jumper to lift
ground, the integrity of the chassis/earth safety
ground connection is never compromised.
(7) AC VOLTAGE MAINS SELECTION “100-
120” or “200-240”
A power entry module with a removable fuse
holder block. This fuse holder block is selectable
for 100 - 120 Volt or 200 - 240 Volt worldwide
mains powering. The fuse block contains two
fuses - one fuse is in series with the hot power
line while the other fuse is in series with the
neutral power line. Both fuses must be installed.
To change the mains voltage selection, remove
IEC power connector and assure that the LOCi is
not connected to mains power. With a non-
conductive tool, gently pry the fuse block away
from the power entry module. Remove the two
fuses and replace both with type as shown
below.
Slide out the internal PC Board, turn it over, and
reinsert the PCB so that the desired AC mains
voltage appears in the viewing window.
Double check that the fuses installed correspond
to the AC mains voltage range which appears in
the viewing window. Gently push the fuse block
back until flush and snug.
FUSES:
For 100-120 VAC mains, use two 5 x 20 mm,
1A, slow blow, 250 V, Littelfuse 218 or equiv.
For 200-240 VAC mains, use two 5 x 20 mm,
1A, slow blow, 250 V, Littelfuse 218 or equiv.
Use only the power cord provided with the LOCi
unit or equivalent U/L approved type SV, SVT,
SJ, or SJT AC power supply cord. Do not defeat
the third pin earth ground. If ground lifting is
desired, remove the Earth/Audio Ground Jumper
Strap (topic #6, above). Export units are not
supplied with a power cord
