Frequently Asked Questions - DENEB 2.5Q DANTE Ram Audio
How do I connect the DENEB 2.5Q DANTE to a Dante network?
Connect an Ethernet cable from your network switch to either the Primary or Secondary Dante port on the rear panel. Ensure your network supports DHCP or configure a static IP. The amplifier will appear in Dante Controller software for audio routing.
What are the power requirements for this amplifier?
The amplifier operates on 100-240 V AC, 50/60 Hz. Use the voltage selector switch on the rear panel to match your local mains voltage. The power consumption is approx. 800 W under full load.
Can I use analog inputs instead of Dante?
Yes, the DENEB 2.5Q DANTE has two balanced XLR analog inputs. When an analog source is connected, the amplifier automatically prioritizes analog over Dante. You can also mix analog and digital sources per channel using the Dante controller.
What is the impedance range for speakers?
The amplifier is stable down to 4 Ω per channel (stereo mode) or 8 Ω bridged. Using lower impedances may cause thermal overload and damage. For 2 Ω loads, the amplifier is not recommended.
How do I bridge the amplifier for more power?
Set the rear panel switch to Bridge Mode (consult manual for exact location). Connect the positive speaker wire to Channel 1 +, and negative to Channel 2 + (not ground). Input signal only on Channel 1 input. The output power becomes 700 W at 8 Ω.
How do I update the firmware?
Firmware updates are performed via the Dante network using Dante Updater software. Download the latest firmware from Ram Audio’s website, run Dante Updater, select the amplifier, and follow the instructions. Do not power off during update.
What do the front panel LEDs indicate?
The green Power LED indicates normal operation. The Signal LEDs (green) illuminate when audio signal is present per channel. The Clip LEDs (red) flash or stay on when the amplifier is overdriven. If the Protect LED (red) is lit, a fault condition exists (short, DC, thermal).
Can the amplifier be used in a 70V/100V distributed system?
No, the DENEB 2.5Q DANTE is a low-impedance amplifier (4-8 Ω) only. For high-impedance systems, you would need an external 70V/100V transformer or a dedicated model.
What is the recommended cleaning and maintenance?
Disconnect power before cleaning. Use a dry or slightly damp cloth to clean the chassis. Do not use solvents. Periodically check air filters (if any) and vacuum dust from vents. Ensure fans are unobstructed. No internal user-serviceable parts.
Where can I find the full user manual?
The full user manual can be downloaded as a free PDF from notice-facile.com or the official Ram Audio support page. It contains detailed setup instructions, wiring diagrams, and specifications.
