Frequently Asked Questions - Receiver Box PRO-JECT

How do I turn on the Receiver Box?

Press the power button on the front panel or use the remote control. The LED indicator will light up when powered on.

Why is there no sound coming from the speakers?

Check that the speaker cables are correctly connected to the terminals and that the impedance matches. Ensure the correct input source is selected and the volume is not muted. Also verify that the amplifier is not in standby mode.

Can I connect a turntable directly?

Yes, the Receiver Box has a built-in phono preamplifier for moving magnet (MM) cartridges. Connect your turntable to the Phono input and set the switch to MM if applicable. For moving coil (MC) cartridges, you may need an external step-up transformer.

How do I reset the device to factory settings?

There is no user reset function. To restore defaults, disconnect the power cord for 30 seconds and reconnect. If issues persist, contact Pro-Ject support.

Does the remote control require line-of-sight?

Yes, the remote uses infrared (IR) signals. Point it directly at the receiver's sensor within a range of about 10 meters. Avoid obstacles between remote and sensor.

What is the recommended speaker impedance?

The amplifier is designed to work with speakers of 4 to 16 ohms. Using speakers with lower impedance may cause overheating or damage.

How do I clean the Receiver Box?

Use a soft, dry cloth to wipe the surface. Do not use any chemical or abrasive cleaners. Avoid getting liquids inside the device.

Can I use it with a subwoofer?

Yes, you can connect a powered subwoofer using the Pre-out output. For passive subwoofers, you would need an external subwoofer amplifier.

Is the Receiver Box compatible with Bluetooth?

The standard model does not include Bluetooth. However, you can add Bluetooth streaming by connecting an optional external Bluetooth receiver to any Line input.

What do the blinking LED lights mean?

A blinking LED may indicate protection mode (short circuit or overheating) or a fault. Turn off the device, disconnect speakers, and let it cool. If the LED continues blinking, contact support.
