7 - GAIN RANGE +/- 10 dB switch:
OUT is bypass, IN changes the +/-20 dB gain ranges on the
LF GAIN (ref. #9) and the HF GAIN (ref. #12) to +/-10 dB,
which allows for more accuracy in dialing in EQ
8 - Low Frequency (LF) In switch:
OUT is bypass; IN inserts the 20 dB boost/cut shelving filter and
variable frequency sweep. The green LED below switch will
indicate when LF EQ is engaged.
9 - Low Frequency Curve Gain control:
This continuously variable control adjusts the LF gain from -20
dB to +20 dB; the slope of the CurveShaper™ EQ varies as
Curve Frequency and Curve Gain settings interact.
10 - Low Frequency Filter control:
This continuously variable control adjusts the -3 dB break-
frequency (as measured at full cut; -20 dB on the LF Gain) of the
filter from 40 Hz to 675 Hz; maximum LF reduction is -20 dB.
11 - High Frequency (HF) In switch:
OUT is bypass; IN inserts the HF EQ circuitry. The green LED
below switch will indicate when HF EQ is engaged.
12 - High Frequency Curve Gain control:
This continuously variable control adjusts the HF gain from
-20 dB to +20 dB; the slope of the CurveShaper™ EQ varies as
Curve Frequency and Curve Gain settings interact.
13 - Curve Frequency control:
This continuously variable control adjusts the +3 dB break-
frequency (as measured at full boost; +20 dB on the HF Gain)
from 2 kHz to 28 kHz.
14 - Audio Signal Level indicators:
The green LED snaps on at -20 dBu to indicate the presence of
signal. The yellow LED snaps on at 0 dBu. The red LED snaps
on at +20 dBu to warn of approaching signal overload.
15 - Power Switch:
OUT is off; IN powers on unit.
Green LED above the switch will indicate that the unit is on.
