Frequently Asked Questions - M2si Musical Fidelity
How do I connect my speakers to the M2si?
Use high-quality speaker cables. Connect the positive terminal of the amplifier to the positive terminal of the speaker, and negative to negative. Ensure the speaker impedance is at least 4 ohms.
Can I use the M2si as a preamp only?
Yes, use the pre-out RCA outputs to connect to an external power amplifier. The internal amplifier stage can be bypassed.
What type of phono cartridge works with the built-in phono stage?
The built-in phono stage is designed for Moving Magnet (MM) cartridges. Moving Coil (MC) cartridges require an external phono preamp.
How do I set up the USB input for my computer?
Connect the M2si to your computer via USB cable. Your computer should recognize it as a audio device. Select the USB input on the amplifier. No driver installation is needed for most systems.
What is the recommended power cable?
Use the supplied power cable. Ensure the voltage matches your local mains (115V or 230V). Do not use extension cords with insufficient rating.
Why is my amplifier not turning on?
Check that the power cable is securely connected and the mains switch is on. Ensure the unit is not in standby mode. If still not working, check the fuse and contact support.
Can I bi-wire my speakers?
The M2si has single speaker terminals. For bi-wiring, you need a speaker that allows it and you must connect the amplifier's single output to both terminals using a jumper or bi-wire cable.
How often should I clean the amplifier?
Clean the exterior with a soft, dry cloth as needed. Avoid using any liquids or sprays. Ensure ventilation slots are free of dust.
What is the warranty period?
Musical Fidelity offers a standard 2-year warranty from the date of purchase. Warranty terms may vary by region.
