Question 1

How to record a radio station with the MAGNAT MR 780 amplifier?

Accepted Answer

The MAGNAT MR 780 amplifier does not have a built-in recording function. To record a radio station broadcast through this device, you need to use external equipment. Here’s how to proceed:

Steps to record radio with the MAGNAT MR 780:

Turn on the amplifier and select the desired radio station in FM/AM tuner mode.
Connect an external recording device to the audio output of the amplifier. This can be a digital recorder, a computer, or another device capable of capturing an audio signal. Use the available RCA or jack outputs on the amplifier.
Start recording on your external device while the radio station is being broadcast through the amplifier.
Check the quality of the recording by adjusting the volume on the amplifier and checking the levels on the recording device.

This method allows you to capture the sound transmitted by the amplifier, as the MAGNAT MR 780 does not offer built-in recording.

Question 2

Are the feet of the MAGNAT MR 780 amplifier adjustable?

Accepted Answer

The MAGNAT MR 780 is equipped with fixed, non-adjustable feet. This design has been deliberately chosen to ensure optimal stability of the device and minimize unwanted vibrations during music playback, which contributes to the overall audio quality.

If you wish to adjust the position of the amplifier or improve its contact with the installation surface, several practical solutions are available. You can use rubber or acoustic foam isolation pads, available in adhesive or disc form, which you will place under each foot to enhance vibrational isolation. Specific audio supports, such as decoupling feet or stabilization platforms, are another alternative to optimize the positioning and stability of the device.

Before installing the amplifier, make sure to place it on a flat and rigid surface, and adhere to the clearance distances recommended by the manufacturer (approximately 10 cm minimum around the device and 20 cm from walls) for adequate ventilation.

Question 3

How to save radio stations on the MAGNAT MR 780 amplifier?

Accepted Answer

Your MAGNAT MR 780 amplifier has two independent station memories for FM and DAB stations, each allowing you to save up to 40 stations. This feature lets you quickly access your favorite stations without having to search for them each time.

Steps to save a station:

Select the desired DAB or FM station using the TUNING buttons on the device or via the remote control, using either automatic search or manual tuning.
Choose a memory location by pressing and holding the corresponding numeric keypad button. For two-digit locations (10 to 40), first press and hold the +10 button, then enter the desired digits.
Wait for the STORED PRESET message to appear on the screen to confirm the successful saving. The display will show the location number followed by the station frequency.

Accessing your saved stations:

To quickly listen to a saved station, briefly press the numeric keypad corresponding to the saved location.
Your various stations will be displayed on the screen with their location number and frequency.

You can save up to 40 stations in each memory, giving you great flexibility to organize your favorite FM and DAB stations according to your listening preferences.

Question 4

How to set the impedance (ohms) on the MAGNAT MR 780 amplifier?

Accepted Answer

The MAGNAT MR 780 amplifier does not have a direct setting for impedance (ohms), as this is a property of the speakers themselves, not the amplifier. Impedance is the electrical resistance that speakers present to the flow of the audio signal. The MR 780 is designed to work with speakers that have an impedance between 4 and 8 ohms.

Before connecting your speakers, check their impedance by consulting their technical manual or the specifications indicated on their label. This value should be within the 4-8 ohm range to ensure optimal operation and avoid overheating or damage to the amplifier. The MR 780 delivers a power of 100 W per channel at 4 ohms or 75 W per channel at 8 ohms, depending on the impedance of your speakers.

To properly connect your speakers to the rear terminals of the MR 780, first prepare your high-quality audio cables (minimum gauge 1.5-2.5 mm²). Strip the ends about 10 mm and twist the wires. Then, unscrew the terminal screws one by one and insert the stripped ends into the side openings. Tighten the screws while ensuring the correct polarity: red or marked (+) wire to the positive terminal, black or unmarked (-) wire to the negative terminal.

You can also use pre-made cables with 4 mm banana plugs or fork connectors, which plug directly into the terminals. The MR 780 accepts bi-wiring, meaning you can use two pairs of cables per speaker (one for bass, one for treble) if your speakers allow it.

If you plan to connect multiple pairs of speakers or wire in parallel, ensure that the total impedance remains at 4 ohms or higher. An impedance that is too low could trigger the amplifier's protection. Also, check your speakers' manual to verify their compatibility with the MR 780.
