CONTROLS DESCRIPTION:
-HI+ TILT:
The -HI+ tilt switch interacts directly with the NF,transitioning
from a gentle filtering of upper frequencies to the natural
openess of the EF86s. The +2 position removes all filtering,
while the "-" positions add a gentle broadcast type hi
frequency roll off. Most effective when the NF knob is
between 11:00 and 5:00, The more Negative Feedback, the
more reactive.
Stock position is
NF or NEGATIVE FEEDBACK:
Turning the "NF" knob counterclockwise reduces the amount
of Negative Feedback, brightening and moving the sound
forward while heightening harmonics and sensitivity. It also
raises total
gain from 42 to 60db. Turning it clockwise
increases the amount of negative feedback, producing a
darker tone with a smooth harmonic structure.
Stock position is
-LOW+ TILT:
The -LOW+ tilt knob boosts and cuts lower frequencies in the
Negative Feedback Loop, dimensionally boosting and moving
the low end from front to back in the soundstage. Most
effective when the NF knob is between 11:00 and 5:00, The
more Negative Feedback, the more reactive.
Stock position is
INPUT:
Next to the phase reverse switch, is a 5-position attenuation
network of 'Balanced H-pads' that go between the mic and
input transformer. The first four positions are for 150 ohm
microphone inputs and are 0, -6, -12, and -19 db. The final
Line (LN) position is for any balanced line level signal such as
tape machines, daw outputs, other preamps, etc.
Stock position is
OUTPUT:
The OUTPUT control knob is placed between the first and
second tube stages. It sets the final level and offers further
manipulation of the two-stage gain structure.
