Built around the finest aspects of our praised V256 vocoder, the Iron Lung is the baby brother housed in our smallest, die-cast chassis . The Iron Lung uses the highest resolution of 256 bands to deliver defined vocoder performance while our famous Gender Bender control lets you adjust a male to female emphasis that delivers numerous and exacting possibilities at the turn of a knob. An XLR input allows your microphone of choice to be used with 3 independent gain controls. To round it out, the tone control integrates with the Gender Bender to refine the tone to exactly where you want it to be. Use a guitar or keyboard for polyphonic delivery. One of the very classic instruments from the past made available to every musician at a classic price!

BASIC AMPLIFIER CONNECTION SETUP
1. Connect your microphone (dynamic mics works 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 Jack on the right side of the Iron Lung.
3. Connect an unbalanced instrument cable from the OUTPUT jack on the left side of the Iron Lung to input of your amplifier.
4. Plug the AC Adapter into a wall outlet.
5. Plug the barrel connector of the AC Adapter into the 9V power jack at the top of the Iron Lung. Polarity is center negative.
6. Turn both knobs to their middle, 12 o'clock 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 talking 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
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-
This knob adjusts the tonal quality of the effect. Fully CCW emphasizes
lower frequencies and fully CW emphasizes higher frequencies.
Additionally as the TONE knob is turned CW from noon, harmonic overtones
are added to the instrument signal to make them sound fuller and
richer. The added harmonic overtones are especially useful when you
using a dry electric guitar straight into the Iron Lung.
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 knob adjusts the amount of formant shift that is
applied to the effected signal. For knob settings above noon, the
formant will shift upward, which is equivalent to shortening the vocal
tract, to sound more female. For knob 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 jack, while the Iron Lung is set to bypass, your
unaffected instrument is output through the OUTPUT jack and the effect
is muted. In effect mode the dry guitar is muted and only the effected
vocal signal is passed through the OUTPUT jack.
SPLIT BYPASS mode: when a TRS Insert Cable is plugged into the OUTPUT
jack before applying power. In bypass mode, the instrument is output on
the TIP of the OUTPUT jack and the vocal is output on the RING of the
OUTPUT jack. 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 cable must be plugged into the Iron Lung's Output jack 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 works best.
MIC INPUT XLR Jack
The MIC INPUT XLR jack is a fully balanced microphone input. Connect
your microphone directly to this input jack. The input impedance at the
MIC INPUT XLR jack is 10 kï�—.
INST INPUT " Jack
Plug the output of your instrument into the INST INPUT jack. The input impedance presented at the INST INPUT jack is 520 kï�—.
INST OUTPUT " Jack
The Iron Lung's effect is output on this jack. In BYPASS mode, this
jack outputs your dry guitar signal. In SPLIT BYPASS mode the jack
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 jack.
Connect this output to your amp, effect pedals or other devices. The
output impedance is 550 ï�—.
9V Power Jack
Plug the output of the Iron Lung's supplied AC Adapter into the 9V power
jack 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.
