EHXO IRON LUNG Vocoder User Manual
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 rack equipment, computer plugins, or large keyboards to get a wide array of classic an 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)
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, the adapter or you. The Iron Lung does not use batteries.
BASIC AMPLIFIER CONNECTION SETUP
- 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.
- Using an unbalanced instrument cable, plug your instrument into the INST Input Jack on the right side of the Iron Lung.
- Connect an unbalanced instrument cable from the OUTPUT jack on the left side of the Iron Lung to input of your amplifier.
- Plug the AC Adapter into a wall outlet.
- Plug the barrel connector of the AC Adapter into the 9V power jack at the top of the Iron Lung. Polarity is center negative.
- Turn both knobs to their middle, 12 o’clock positions.
- Set the Mic Gain switch to the middle position.
- 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 microphone.
- 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 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.
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 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 k.
INST INPUT ¼” Jack
Plug the output of your instrument into the INST INPUT jack. The input
impedance presented at the INST INPUT jack is 520 k.
INST OUTPUT ¼” 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 .
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.
