LOCi FRONT PANEL
(1) INPUT SELECT PUSHBUTTON Switches
(L&R)
Select either IN - MM (Moving Magnet)
connected to Input 1, or OUT MC (Moving Coil)
connected to inputs 2 or 3.
(2) MONO SELECT SWITCH "MONO (L+R)"
Pushbutton switch (German ITT) which combines
left and right inputs into a summed mono signal.
When this switch is depressed and illuminated,
left and right input signals are combined into a
single mono signal sent to both left and right
compensation and filter path inputs.
(2) POLARITY REVERSE SWITCH "POL REV"
Pushbutton switch (German ITT) which, when
depressed and illuminated, reverses the polarity
(180 degree inversion) of the right channel input
signal. Use with vertical groove recordings or
stereo sources which are in reversed polarity
relative to each other.
(4) SIGNAL PRESENT & OVERLOAD
INDICATORS "SP" & "OL"
Green and red LEDs (light emitting diodes)
which show signal activity (green) and high-level
(red). The green Signal Present LED illuminates
with an audio signal level of approximately -30
dBu, and should illuminate with any normal
phono input signal. The red high-level LED
illuminates with an audio signal level of
approxi20 dBu at the Post EQ output
XLR jacks and should only illuminate on the very
highest peak levels.
(5) HIGH RESOLUTION PHONO GAIN
CONTROL
Detented, 36-position gain control employing a
Grayhill mil-spec gold plated rotary switch.
Switch gain is approximately 1.5 dB per step
and is inter-channel matched to better than 0.08
dB at all settings. After a brief warm-up period,
adjustment of this switch is virtually silent. Two
illuminating pushbutton switches ("A" = Green
and "B" = Amber) determine the gain "range" of
the rotary switch.
When the pushbutton switches are not
depressed and non-illuminated, the phono
preamplifier gain is as printed on the front panel
(9.0 dB, 10.5 dB, 12.0 dB, etc..).
When the green "A" pushbutton switch (only) is
depressed and illuminated, add 18 dB to the
gain settings as printed on the front panel.
When the green "A" and amber "B" switches are
both depressed and illuminated, add 36 dB to
the gain settings as printed on the front panel.
For example, with both pushbutton switches
depressed and the rotary switch at 1:00 o'clock
position, the preamp gain would be 55.5dB
(19.5 + 36).
(6) BAND IN/OUT SWITCH "IN"
Pushbutton switch which places its associated
EQ band in circuit or out of circuit. There are
eight bands of equalization on the LOC Analog
Legacy.
Four bands provide precise phono compensation,
including RIAA and an unlimited number of
legacy curves.
Four additional bands (marked "FILTER") provide
additional sculpting and repair tools. An EQ band
is in-circuit when its associated band switch is
depressed and LED is illuminated. Band In/Out
switches are provided both for comparing a
single EQ band setting versus flat-band
response, and for bypassing any band entirely,
such as with flat acoustic recordings.
(7) FREQUENCY SELECT ROTARY SWITCH
Six position rotary switch (Grayhill, gold
contacts, military spec) which selects fixed high
and low band frequency points.
LF compensation frequencies are preset to 200,
250, 300, 400, 500/RIAA, and 700/USER (in
Hz).
HF compensation frequencies are preset at 10
kHz to -5.0, -7.0, -9.5, -11.5, -13.7/RIAA, and -
16.0/USER (in dB).
Where a switch is marked "USER", the user may
change the value of a fixed capacitor to allow for
virtually any compensation frequencies not
preset on the factory stock rotary switch points.
See printed circuit board diagram on page 8 for
capacitor socket location (C14 on LF board and
C8 on HF board).
