Q: What are the 2 ohm impedance specifications for the KD-R462?

The KD-R462 has a maximum output power of 50 W × 2 when a 4 Ω subwoofer is connected. However, the recommended impedance for this model is 4 Ω to 8 Ω . Although the manual indicates a specification at 2 ohms, it is not recommended to use an impedance lower than 4 ohms for this device. Operating below this minimum impedance can cause an overload of the amplifier and damage both the receiver and your speakers. For your safety and that of your equipment, ensure that your speakers or subwoofer comply with the recommended impedance of 4 Ω - 8 Ω.

Question 6

Does the JVC LT-24FD120 television have Bluetooth?

Accepted Answer

No, this JVC LT-24FD120 television does not have Bluetooth.

According to the technical specifications in the manual, the available ports on this device are:

2 HDMI ports
1 USB port
1 VGA port
1 RF port (antenna)
1 Mini AV port (composite video)
1 coaxial connector (audio output)
1 3.5 mm headphone jack
1 PC Audio jack

The model does not have Bluetooth or built-in WiFi. If you want to connect a wireless device (speaker, headphones, phone...), you can:

Use the 3.5 mm headphone jack for wired headphones or earphones
Connect an external WiFi decoder (IPTV box, Android TV Box) to one of the HDMI ports to access internet services and more connectivity

Question 7

What are the 2 ohm impedance specifications for the KD-R462?

Accepted Answer

The KD-R462 has a maximum output power of 50 W × 2 when a 4 Ω subwoofer is connected. However, the recommended impedance for this model is 4 Ω to 8 Ω.

Although the manual indicates a specification at 2 ohms, it is not recommended to use an impedance lower than 4 ohms for this device. Operating below this minimum impedance can cause an overload of the amplifier and damage both the receiver and your speakers.

For your safety and that of your equipment, ensure that your speakers or subwoofer comply with the recommended impedance of 4 Ω - 8 Ω.

Question 8

What output voltage can the JVC KD-R462 deliver?

Accepted Answer

The JVC KD-R462 sends a pre-amplified output voltage (pre-out/line) of 2,500 mV (2.5 volts) maximum on a 10 kΩ load. This voltage is constant and does not vary with the volume setting of the player - it is the standard line level, used to connect external amplifiers or audio signal processors.

The output impedance of the preamplifier is ≤ 600 Ω, ensuring clean transmission to your external equipment.

If you are looking for audible power (speaker output), the JVC KD-R462 delivers 50 W × 4 channels (or 50 W × 2 + 50 W × 1 for subwoofer) at 4 Ω on its built-in amplifier outputs.

Question 9

Where is the power reset button on the JVC RA-F320B?

Accepted Answer

The JVC RA-F320B radio has a reset function (power reset), although the Reset button is not explicitly identified in the control diagram.

To perform a power reset, follow these steps:

Turn off the radio
Press and hold the Power button and the Reset button simultaneously for a few seconds
The screen will turn off and then back on, confirming the reset

If you have trouble locating the Reset button on your device, carefully check the small buttons on the sides or back of the radio. As a last resort, you can contact Darty support at 0 978 970 970.

Question 10

Why does my JVC RA-F320B crackle when saving radio stations?

Accepted Answer

The crackling during saving usually indicates a problem with radio reception rather than the saving process itself. Here’s how to fix it:

Correct saving procedure

Use the ▲/▼ buttons to tune into a clear FM station (87.5-108.0 MHz).
Press and hold the SET button until the MEM indicator appears and “01” starts blinking.
With the number still blinking, press ▲/▼ to choose the memory number (up to 10 FM stations).
Press SET again to confirm the recording.

Solutions to crackling

Antenna: Fully extend the wired FM antenna at the back and position it correctly. A partially folded antenna always causes crackling.
Interference: Keep the radio away from fluorescent lamps and nearby electronic devices (TV, microwave, etc.).
Volume: Ensure the volume is not too low (range L01-L15). A very low volume can amplify noise.
Local signal: Check that a reliable FM station is broadcasting properly in your geographical area.

If after these checks the crackling persists, the problem lies with the quality of the radio signal in your location, not with the device or the saving process.
