1 ~ 20 kHz
The outer concentric knob sweeps the EQ Fre-
quency between 1,000 and 20,000 Hz.
-15 ~ +15 dB
The inner concentric knob adjusts the gain of the
set frequency band by plus or minus 15 dB. A
center detent is provided for unity gain.
10. HIGH-MID
Q
This rotary control adjusts the Q (the bandwidth)
of this section of the equalizer from a very narrow
band to a very broad band, with a center detent
at a Q of 1.2.
0.4 ~ 8 kHz
The outer concentric knob sweeps the EQ Fre-
quency between 400 Hz and 8,000 Hz.
-15 ~ +15 dB
The inner concentric knob adjusts the gain of the
set frequency band by plus or minus 15 dB. A
center detent is provided for unity gain.
11. LO-MID
Q
13. EQ (In/Out switch)
This locking switch activates the channel EQ or
bypasses it completely. The EQ is active when the
switch is engaged (and the LED in it is on). Bypass
allows for A-B comparison, and absolutely mini-
mum signal degradation when EQ is not needed.
14.
HPF (H.P. filter in/out switch and control)
This locking switch activates the input channel
HIGH PASS FILTER or bypasses it. The filter is
active when the switch is engaged (and the LED in
it is on). This filter bypass function is independent
of the EQ section, which has its own bypass switch.
20 ~ 400Hz
This rotary control adjusts the Q (the bandwidth)
of this section of the equalizer from a very narrow
band to a very broad band, with a center detent
at a Q of 1.2.
80 Hz ~ 1.6kHz
The outer concentric knob sweeps the EQ Fre-
quency between 80 Hz and 1,600 Hz.
-15 ~ +15 dB
The inner concentric knob adjusts the gain of the
set frequency band by plus or minus 15 dB. A
center detent is provided for unity gain.
12. LO (Peak/Shelf)
This locking switch selects peaking type EQ
(switch out) or shelving type EQ (switch en-
gaged). When the switch is engaged (shelving
mode), the adjacent Q control is not operational.
Q
This rotary control sweeps the cutoff frequency of a
high pass filter (or "low cut" filter) from 20 Hz to
400
Hz. The filter slope is 12 dB per octave.
Typical applications including cutting wind noise,
vocal "P" pops, stage rumble, and low frequency
leakage from adjacent instruments. You can use
higher frequency settings to reduce leakage into
mics that are primarily handling high-frequency
sources. It is a good practice to use the filter to
protect woofers from unnecessary over-excursion
due to the presence of unneeded low frequency or
sub-sonic components, especially if a microphone is
dropped or kicked. Bypass the filter (switch up)
only when you want very low frequencies, as with
an organ, drum, bass guitar, and so forth.
15. INSERT PRE
The insert in point is normally after the HPF and
equalizer. Engaging this switch moves the insert
point between the equalizer (pre-EQ) and the
HPF. The LED in the switch is on when the
insert point is pre EQ.
16. INSERT ON
This rotary control adjusts the Q (the bandwidth)
of this section of the equalizer from a very narrow
band to a very broad band, with a center detent
at a Q of 1.2.
30 Hz ~ 600 Hz
The outer concentric knob sweeps the EQ Fre-
quency between 30 and 600 Hz.
-15 ~ +15 dB
The inner concentric knob adjusts the gain of the
set frequency band by plus or minus 15 dB. A
center detent is provided for unity gain.
This locking switch activates the channel’s
INSERT IN jack, from which it applies signal to
the rest of the channel (see item [15] also). The
INSERT OUT jack is always “live,” and this
switch does not affect it. The primary use of this
switch is to select or de-select any signal proces-
sor or independent line input source which may
be plugged into INSERT IN. When the switch is
engaged, making the Insert In jack “live,” the
LED in the stitch is on.
If there is nothing plugged into the INSERT IN
jack, this switch has no effect.

NOTE: PM3000 users will notice there is no EQ CLIP
indicator. Clipping at this stage can occur even though
the input signal is not clipping, due to boost (gain)
applied with the EQ circuitry. In the PM4000, clipping
in the equalizer is detected and shown on the PEAK
indicator [7] adjacent to the GAIN control.
