Phase Flip; Comp Section; Boost; Sansamp Section - Tech 21 The Acoustic Fly Rig NYC Owner's Manual

GUIDE TO FUNCTIONS and CONTROLS
(in order of signal flow)

PHASE FLIP

Reverses the input of the guitar signal to help combat feedback.When
out, the output is in phase with the input.When in, the output is re-
versed. If your instrument feeds back, try positioning the switch in to
reverse the phase. If the feedback remains, return the Phase Flip switch
to the out position before proceeding with diagnosing the cause. (Refer
to Noteworthy Notes on pages 7-8.)

COMP Section

Utilizes old school, all-analog, FET-based technology from the '50s and
'60s, which is inherently warmer, more transparent and more musical
than other methods of compression.
A single, continuously variable control allows you to dial in just the
right amount of compression you need. A little goes a long way, from
soft and barely noticeable to super squashy, infinite sustain.
LEVEL: Adjusts the output level of the Comp section.

BOOST

Independent Boost for solos, up to approx. 12dB.
Includes a wide mid-range boost for improved
clarity.

SANSAMP Section

SANSAMP ON: Engages the all-analog SansAmp technology which
enables the Acoustic Fly Rig to run directly into mixers of recording
desks and PA systems. Sweepable, semi-parametric, active EQ controls
provide professional grade tweakability for any situation.
NOTCH: Sweepable from 70Hz to 350Hz.To engage, push the corre-
sponding switch in. It is designed to diminish the sensitivity for feedback,
caused by the resonating, low acoustical frequency of your guitar. Effec-
tive, yet gentler than most notch filters, it should not adversely alter
the tone. For an average size and weight acoustic guitar, a setting of
150Hz should be adequate. Different models and sizes, however, may
require further adjustment.
VOLUME: Adjusts the output level of the unit when the SansAmp
section is engaged.This control has an exceptionally wide range for
maximum compatibility with a variety of equipment.
LOW and HIGH: On-board post-EQ section gives you full control,
like having a studio mixing board at your fingertips. Unlike passive tone
controls that only cut, these active shelving EQs cut or boost ±18dB
from unity gain at 12 o'clock, with pivot point at 1kHz.
MID and MID SHIFT: Sweepable, semi-parametric EQ controls
range from 150Hz to 3.2kHz, ±15dB, respectively.With the Mid Shift
control, you can select the center frequency of the mid-range (Mid)
control. Note: If you set Mid Shift at 12 o'clock, Mid operates as a tra-
ditional mid-range control.
LOW PASS FILTER: Sweepable from 1.5kHz to 20kHz, rolls off un-
desirable frequencies and artifacts.
