IRON LUNG
Vocoder
Congratulations on your purchase of the Electro-Harmonix Iron Lung Vocoder. The Iron Lung
is a versatile and easy to use vocoder in a compact pedal format. Musicians no longer need
large rac equipment, computer plugins, or large eyboards to get a wide array of classic and
modern vocoder sounds. The Iron Lung includes the same popular vocoding algorithm as the
V-256.
Special Features of the Iron Lung:
 256 band Vocoder
 TONE and GENDER BENDER controls
 Guitar Bypass or Split Guitar/Vocal Bypass (requires Insert Cable)

BASIC AMPLIFIER CONNECTION SETUP
1. Connect your microphone (dynamic mics wor s best since the Iron Lung does not
provide Phantom Power) to the MIC input on the right side of the Iron Lung using a
balanced XLR cable.
2. Using an unbalanced instrument cable, plug your instrument into the INST Input Jac on
the right side of the Iron Lung.
3. Connect an unbalanced instrument cable from the OUTPUT jac on the left side of the
Iron Lung to input of your amplifier.
4. Plug the AC Adapter into a wall outlet.
WARNING: Use only the AC Adapter that the Iron Lung comes
supplied with. Do not use any other AC Adapters. Using other AC
adapters, even those made by Electro-Harmonix, could cause harm to
the unit, t
he adapter or you. The Iron Lung
does not use batteries.

5. Plug the barrel connector of the AC Adapter into the 9V power jac at the top of the Iron
Lung. Polarity is enter negative .
6. Turn both nobs to their middle, 12 o’cloc positions.
7. Set the Mic Gain switch to the middle position.
8. Push the MIC BYPASS footswitch until its associated LED is lit. Play your instrument,
while singing or tal ing into the microphone. You should hear the vocoding effect.
Remember you will only output from the Iron Lung when you are playing your
instrument and speaking into the mi rophone.
9. If you connect a guitar to the input of the Iron Lung, try adding a distortion pedal
between your guitar and the Iron Lung, this will help to emphasize the vocoder effect.
- CONTROLS, INDICATORS & I/O-
TONE
This nob adjusts the tonal quality of the effect. Fully CCW emphasizes lower frequencies and
fully CW emphasizes higher frequencies. Additionally as the TONE nob is turned CW from
noon, harmonic overtones are added to the instrument signal to ma e them sound fuller and
richer. The added harmonic overtones are especially useful when you using a dry electric
guitar straight into the Iron Lung.
GENDER BENDER
Formant shift corresponds roughly to the length of the vocal tract. Bass and baritone singers
have longer vocal tracts than sopranos and tenors.
The GENDER BENDER nob adjusts the amount of formant shift that is applied to the effected
signal. For nob settings above noon, the formant will shift upward, which is equivalent to
shortening the vocal tract, to sound more female. For nob settings below noon, the formant
will shift downward, which is equivalent to lengthening the vocal tract, to sound more male.
At noon, there is no formant shift.
BYPASS FOOTSWITCH / STATUS LED
The BYPASS footswitch toggles the Iron Lung between effect mode and bypass mode. If the
STATUS LED is lit, then the Iron Lung is in effect mode. If the STATUS LED is off, then the
Iron Lung is in bypass mode.
NORMAL BYPASS mode: when a standard mono guitar cable is plugged into the Iron
Lung’s output jac , while the Iron Lung is set to bypass, your unaffected instrument is output
through the OUTPUT jac and the effect is muted. In effect mode the dry guitar is muted and
only the effected vocal signal is passed through the OUTPUT jac .
SPLIT BYPASS mode: when a TRS Insert Cable is plugged into the OUTPUT jac before
applying power. In bypass mode, the instrument is output on the TIP of the OUTPUT jac and
the vocal is output on the RING of the OUTPUT jac . In effect mode, the effect will be

present on both the Tip and Ring of the insert cable. NB: in order to use Split Bypass, the
insert able must be plugged into the Iron Lung’s Output ja k before applying
power to the Iron Lung.
MIC GAIN TOGGLE SWITCH
Use this switch to change the sensitivity of the mic pre-amp in the Iron Lung. Experiment
with your setup to see whether LO, MID, or HI gain mode wor s best.
MIC INPUT XLR Ja k
The MIC INPUT XLR jac is a fully balanced microphone input. Connect your microphone
directly to this input jac . The input impedance at the MIC INPUT XLR jac is 10 Ω .
INST INPUT ¼” Ja k
Plug the output of your instrument into the INST INPUT jac . The input impedance presented
at the INST INPUT jac is 520 Ω .
INST OUTPUT ¼” Ja k
The Iron Lung’s effect is output on this jac . In BYPASS mode, this jac outputs your dry
guitar signal. In SPLIT BYPASS mode the jac outputs dry guitar signal to the TIP and MIC
vocal to the RING of an Insert Cable (enabled when the Iron Lung is powered up with an
Insert Cable plugged into the OUTPUT). While in effect mode, the effect signal is present on
both the Tip and Ring contacts of the OUTPUT jac . Connect this output to your amp, effect
pedals or other devices. The output impedance is 550 Ω .
9V Power Ja k
Plug the output of the Iron Lung’s supplied AC Adapter into the 9V power jac located at the
top of the Iron Lung. The Iron Lung requires 9 to 9.6VDC at 200mA with a center negative
plug. The Iron Lung accepts Boss style AC Adapters.
