Frequently Asked Questions - Intelligent Harmony Machine Electro Harmonix
How do I connect the Intelligent Harmony Machine?
Connect your guitar to the INPUT jack and the OUTPUT jack to your amplifier or next pedal. Use a 9V DC center negative power supply or a 9V battery. Turn the volume down before connecting.
How do I set the key for harmony?
Press the KEY button and rotate the knob to select the desired key (A through G, with sharps/flats). The LED will indicate the key. The pedal will then generate harmonies based on that key.
What harmony intervals can I choose?
Use the INTERVAL knob to select intervals like 3rd, 5th, octave, and more. The MODE button changes between major and minor intervals. The specific intervals are listed on the pedal's face.
Can I use this pedal with a bass guitar?
Yes, the Intelligent Harmony Machine works with bass guitars. The harmony tracking is designed to handle low frequencies, but results may vary depending on your playing style.
How do I achieve true bypass?
The pedal has true bypass by default. When the effect is off, the signal passes through directly without coloration. A relay ensures pristine switching.
What is the battery life?
With a fresh 9V alkaline battery, expect approximately 20 hours of continuous use. For longer sessions, use an optional 9V DC power supply (center negative).
Can I power multiple pedals from one supply?
Yes, you can use a daisy chain power cable, but ensure the total current draw does not exceed the supply's capacity. The Intelligent Harmony Machine draws 150 mA.
How do I clean and maintain the pedal?
Use a soft, dry cloth to wipe the exterior. Avoid liquids, solvents, or abrasive cleaners. Keep away from moisture, dust, and extreme temperatures.
Is there any latency with the harmony effect?
The pedal uses 24-bit digital processing with very low latency, typically less than 3 ms. It is barely noticeable in most playing situations.
What should I do if the pedal stops working?
First, check the power supply and battery. Ensure cables are firmly connected. If issues persist, contact Electro Harmonix support or an authorized service center. Do not attempt internal repairs.
