Frequently Asked Questions - DALIMa 20Q Ram Audio
How do I connect speakers to the DALIMa 20Q?
Use Speakon connectors on the rear panel for each channel. Ensure the amplifier is turned off before connecting or disconnecting speakers.
Can I bridge two channels for more power?
Yes, the DALIMa 20Q supports bridging. Set the mode switch to 'Bridge' and connect the speaker to the bridged output terminals. This doubles the power output.
What is the correct power cable for this amplifier?
Use a heavy-duty IEC C19 power cable rated for at least 15A. The amplifier requires a grounded outlet.
The amplifier goes into protect mode frequently. What should I do?
Check for shorted or faulty speaker cables, ensure load impedance is not below the minimum (2 ohms per channel in stereo, 4 ohms bridged). Also verify proper ventilation and that the unit is not overheating.
How do I clean the DALIMa 20Q?
Disconnect power. Wipe the front panel and chassis with a soft, dry cloth. Use compressed air to blow dust from the front ventilation grille and rear fan intake.
What is the minimum impedance per channel?
The amplifier is stable down to 2 ohms per channel in stereo mode and 4 ohms in bridge mode.
Can I use this amplifier in a 100V line system?
No, the DALIMa 20Q is a low-impedance amplifier designed for 2, 4, or 8 ohm speakers. It does not support 100V line transformers.
Does the unit have a built-in crossover?
Yes, each channel features a selectable high-pass filter (30 Hz or 50 Hz) to protect subwoofers and reduce low-frequency waste.
What is the correct rack mounting procedure?
Use the included rack ears and M5 screws. Ensure support brackets are used for heavy amplifiers. Allow at least 1U space above and below for ventilation.
How do I interpret the clip LED indicators?
The clip LEDs illuminate when the input signal is too high, causing distortion. Reduce the input level until the LED flashes only occasionally on peaks.
