Frequently Asked Questions - HDA-4.90 Black Hydra
How do I connect the receiver to my TV?
Connect the HDMI OUT port to your TV's HDMI input. If you are using an older TV, use the composite or component video outputs. Make sure to select the appropriate input source on the receiver.
How can I set up the FM radio?
Press the FM/AM button on the remote or front panel. Then use auto search to scan and save stations. For manual tuning, press the tuning up/down buttons. Save preset stations using the preset memory function.
Why is there no sound from the speakers?
Check that the speaker connections are secure and that the impedance matches the receiver. Ensure the sound mode is not set to "Mute" and that the correct input is selected. Verify the A/V sync and level adjustments in the speaker setup menu.
Can I control the receiver with my smartphone?
Yes, the receiver supports Bluetooth and Wi-Fi, so you can use the Black Hydra Remote app available for iOS and Android. This app allows you to control volume, inputs, and even access streaming services.
How do I clean the receiver?
First unplug the unit. For the exterior, use a soft, lint-free cloth slightly dampened with water. Do not use solvents or abrasive cleaners. For the ventilation openings, use a vacuum cleaner with a brush attachment to remove dust.
What safety precautions should I take?
Place the receiver on a flat, stable surface with at least 10 cm of clearance around the vents. Avoid exposing it to moisture, direct sunlight, and heat sources. Do not block the ventilation openings and unplug during thunderstorms or when not in use for extended periods.
Where can I find spare parts?
Spare parts such as remote controls, power supplies, and HDMI boards can be ordered through the Black Hydra support website or from authorized service centers. Provide your model number HDA-4.90 for the correct part.
How do I perform a factory reset?
To reset the receiver to default settings, press and hold the Pure Audio button for 5 seconds while the unit is in standby. Alternatively, navigate to the System Setup menu and select Reset. This will erase all your settings and return to factory defaults.
How can I update the firmware?
Check the Black Hydra support website for the latest firmware for the HDA-4.90. Download it to a USB drive and insert it into the USB port on the front. Then go to System Setup > Firmware Update and follow the on-screen instructions.
What is the recommended ventilation clearance?
It is recommended to leave at least 10 cm of space above, below, and on the sides of the receiver for proper heat dissipation. Ensure that the ventilation slots are not covered by curtains or other objects, and place the unit in a well-ventilated area.
