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

How to resolve the issue of no sound when connecting Bluetooth between an iPod and the JVC KDT925BTS?

Accepted Answer

If you do not hear any sound when connecting your iPod to the JVC KDT925BTS via Bluetooth, follow these precise steps to resolve the issue:

1. Check that the BT AUDIO source is selected

Press the SOURCE button (or B SRC on the front panel) repeatedly until BT AUDIO appears on the screen.
This is the most important step: if the source is not set to BT AUDIO, no sound can be heard even if the device is connected.
Also check in the menu that [SOURCE SELECT] has BT AUDIO enabled (set to [ON]).

2. Properly adjust the volume levels

Turn the volume knob on the JVC KDT925BTS to increase the sound to an audible level (at least 10-12).
Also increase the volume on your iPod itself.
Check that the JVC is not in mute mode: press the volume button to unmute if the mute icon is displayed.

3. Confirm the Bluetooth connection

Check that your iPod is properly connected to the JVC KDT925BTS in the Bluetooth settings of the iPod (should display the name "KD-T925BTS").
Make sure Bluetooth is enabled on your iPod.
If you are also using a USB connection for the iPod, note that the USB connection takes precedence over Bluetooth: unplug the USB cable if you want to use only Bluetooth.

4. Reactivate the Bluetooth connection

Turn off Bluetooth on your iPod, wait 5 seconds, then turn it back on.
If that doesn't work, completely turn off the JVC KDT925BTS (detach the front panel) and turn it back on.
Restart playback on your iPod after rebooting.

5. Delete and re-pair the device

On the JVC KDT925BTS, access the menu by pressing the volume button, then select [BT MODE] → [DEVICE DELETE].
Turn the volume knob to select your iPod from the list, then press to confirm.
Select [YES] to delete the pairing.
On your iPod, remove the JVC from the list of known Bluetooth devices.
Restart pairing by searching for "KD-T925BTS" from your iPod and confirm the pairing with the PIN 0000 if prompted.

6. Reset Bluetooth settings if the problem persists

Go to the JVC menu and select [BT MODE] → [INITIALIZE].
Select [YES] to reset all Bluetooth settings (pairings, phonebook, etc.).
Then proceed with a new complete pairing with your iPod.
Once reconnected, adjust the volume again and check that BT AUDIO is selected as the source.

If after these steps you still have no sound, test with another Bluetooth device (phone, tablet) to determine if the issue is with the JVC KDT925BTS or your iPod.
