NSEQ-2
NSEQ-2 FRONT PANEL
(1) BAND IN/OUT SWITCH "IN"
Pushbutton switch which places its EQ band in circuit or out of circuit. EQ band is in circuit
when switch is depressed and LED is illuminated. Because of the NSEQ-2's unique shunt de-
sign, EQ bands should have no detectable sonic signature when they are in circuit as long as the
boost/cut control (4) is set at zero. Band In/Out switches are provided for comparing a band's
EQ setting versus flat response.
(2) FREQUENCY SELECT SWITCH
Rotary switch (gold contacts, mil spec) which selects fixed high and low band frequencies.
(3) PEAK/SHELF SWITCH
Pushbutton switch which selects high and low band curve shape. When switch is depressed and
LED is illuminated, EQ is shelving at 6 dB per octave. When switch is not depressed, EQ is
peaking with a fixed "Q" of 1.0.
(4) BOOST/CUT CONTROL
Conductive plastic rotary potentiometer offering up to +20 dB of boost and -20 dB of cut. Can
also be configured for +/-10 dB via master gain range switch (10). Boost/Cut Potentiometer has
21 detented positions for accurate repeatability and logging.
(5) PARAMETRIC FREQUENCY CONTROL
Conductive plastic rotary potentiometer which sweeps all center frequencies from 20 Hz to 25
kHz. The low-mid band sweeps 20 Hz to 220 Hz -or- 220 Hz to 2.5 kHz, depending on the sta-
tus of frequency range switch (6). The high-mid band sweeps 250 Hz to 2.5 kHz -or- 2.5 kHz
to 25 kHz, depending on the status of Frequency Range Switch (6). This control is optionally
available with 21-step detents for accurate repeatability and logging.
(6) PARAMETRIC FREQUENCY RANGE SWITCH "10X"
Pushbutton switch which selects 1X or 10X parametric frequency range. When switch is de-
pressed and corresponding LED is illuminated, frequencies as shown on front panel legend are
multiplied by 10X. When switch is not depressed and LED is not illuminated, frequencies are as
shown on front panel legend.
(7) PARAMETRIC QUALITY CONTROL "Q"
Conductive plastic rotary potentiometer which sweeps "Q" (Quality factor) from 0.4 to 4.0. "Q"
is defined as the ratio of the center frequency to the bandwidth. For example, a filter setting
with 3 dB down points near 100 Hz and 1000 Hz exhibits a "Q" of approximately 0.4.
This control is optionally available with 21-step detents for accurate repeatability and logging.
(8) MASTER CHANNEL IN/OUT SWITCH "IN"
Pushbutton switch which places the corresponding four band EQ channel in circuit or out of
circuit. EQ channel is in circuit when switch is depressed and LED is illuminated. When switch
is not depressed, or when NSEQ-2 power is off, the EQ channel is completely bypassed via a
relay and inputs become hard-wired directly to outputs.
