Common issues, fixes, power linking, thermal management, and setup tips.
My ATL328 Milan™ network audio is not initializing — what should I check?
First, verify that your AVB/TSN network switch is Milan™ certified and properly configured for AVB traffic prioritization. Check that the ATL328 is connected via its primary network port and receiving link activity (LED indicator should be solid or blinking). Ensure your Milan controller software detects the device; if not, power cycle the ATL328 and confirm the network cable is Cat5e or better with proper termination. If using a Dante bridge, verify the bridge is online and the stream format matches (48kHz sample rate typical).
How do I set proper delay and alignment for a flown ATL328 array?
Access the DSP on each ATL328 module via the Akro Command software and measure the physical distance from each cabinet to the primary listening position using a laser measure. Apply delay compensation at 1.1ms per foot (or 3.6ms per meter) of additional distance for any delayed fills or out-riggers. For the main flown array, ensure all boxes in the cluster share identical delay settings unless intentionally shading coverage. Use measurement software with a reference microphone to verify phase alignment between array sections and confirm the house EQ matches the predicted coverage pattern.
My ATL328 is going into thermal shutdown — what are the cooling and duty cycle requirements?
The ATL328 requires adequate airflow around its rear amplifier section; ensure a minimum 4-inch clearance from walls or other cabinets when ground-stacked. For sustained high-SPL operation (above 125dB continuous), ambient temperatures should not exceed 35°C (95°F). If arrays are covered with weather protection, use breathable material that doesn't trap heat. Reduce output level by 3-6dB during extended peak-demand periods in hot environments.
My IMP205 won't power on when daisy-chained to other units — what's wrong?
Check the power linking configuration on your IMP205 chain. If too many units share a single AC feed, the protection circuit may prevent power-up. Try disconnecting units and running separate AC feeds to additional modules. Verify that the IP locking power connectors are fully seated and the AC source provides stable voltage (not a long extension cord run causing voltage drop). Check that the circuit breaker rating can handle the combined current draw of all linked units.
My IMP118 in cardioid mode has very low output — what am I doing wrong?
Cardioid mode on the IMP118 requires proper physical placement: the rear-firing subwoofer must be positioned against or near a boundary (wall or stage rear) with the correct spacing from the front sub. If placed in open air without a boundary, cancellation occurs at all frequencies rather than selectively at the rear. Verify the cardioid DSP setting is correctly selected (not end-fire, which requires different spacing). Confirm that both the front and rear subs have identical input signal with proper polarity — reversed polarity will cause full cancellation rather than rear rejection.
I'm getting phasing issues between my IMP205 tops and IMP118 sub — how do I fix alignment?
First, verify that all units have the same polarity setting — an inverted sub will cause severe cancellation in the crossover region. Measure the physical distance from each cabinet's driver to the listening position and apply delay to the closer cabinet (typically the sub if ground-stacked forward of flown tops). Use a measurement mic and analysis software to check phase correlation at the crossover frequency (typically 80-120Hz); adjust delay in 0.1ms increments until maximum summation is achieved. Ensure the IMP118 crossover setting matches your system's high-pass on the IMP205.
The clip LED on my IMP205 stays on even at moderate levels — how should I gain stage?
The IMP205 clip LED indicates the input stage or amplifier is being overdriven. Start by reducing the output level on your mixing console or processor until clipping stops, then adjust the IMP205 input sensitivity switch to match your source level (line level vs. lower output devices). Avoid boosting EQ excessively at the source, as this eats headroom before the signal reaches the speaker. If clipping persists, check that no upstream device (mic preamp, channel strip, main fader) is clipping — digital clipping passes through as persistent distortion regardless of downstream gain settings.
I'm getting feedback with my AS8 in a small room — how do I fix it?
Position the AS8 columns in front of and facing away from all microphones — column speakers have narrow vertical dispersion, so elevation matters. Use the built-in 2-band EQ to cut the frequency where feedback occurs (typically 2-4kHz for intelligibility-focused speech systems or 250-500Hz for room boom). Keep microphones at least 6 feet from the front of any speaker column. If feedback persists, use a parametric EQ at your mixer to notch out the specific ringing frequency. Avoid placing the system in room corners, which amplify standing waves and make feedback more likely.
My A12X / A15X Bluetooth won't connect to my phone — how do I reset pairing?
Access the DSP menu via the rear LCD screen and navigate to the Bluetooth settings. Select 'Clear Pairings' or 'Reset BT' to remove all stored devices. Exit the menu and the speaker will enter discoverable mode. On your phone, go to Bluetooth settings, forget any existing A12X/A15X entries, then scan for new devices. The speaker should appear as 'A12X' or 'A15X' — select it to pair. If it still fails, power cycle the speaker and ensure no other device within range is attempting to auto-connect to the speaker's Bluetooth.
I have no audio output from my Avante speaker — how do I systematically troubleshoot?
Start at the source: verify signal is leaving your mixer (meters showing output, headphone check). Confirm the XLR cable is connected to a line output, not a mic-level or aux send requiring gain. Check that the cable runs to the speaker's INPUT jack, not link/thru output. On the speaker, verify power LED is lit and input gain is above minimum. If using a mic directly, ensure phantom power is off unless required by a condenser mic. Swap the XLR cable with a known-good cable. If multiple speakers are daisy-chained, test each individually to isolate the fault. Check that no limiter or mute is engaged on the speaker's DSP.
I'm hearing distortion at moderate volume levels — how should I set gain staging?
Distortion at moderate levels typically indicates clipping at a gain stage before the speaker. Start with your mixer's channel gain: set input trim so peaks reach -6dB to -3dB on the channel meter, never hitting red. Keep channel faders near unity (0dB) and control overall level with the master fader. The speaker's input sensitivity should match your mixer's output level (typically +4dBu for pro gear). If distortion persists, check that no EQ boost is adding gain that pushes the signal into clipping. Use a limiter at the mixer output if transient peaks are too aggressive for the system's headroom.
How do I register a warranty claim for my Avante product?
Email support@avanteaudio.com with your proof of purchase (invoice from authorized dealer), product serial number (located on rear panel label), description of the defect, and your contact information. Include photos or video demonstrating the issue if applicable. Avante's 2-year limited warranty covers manufacturing defects but not damage from misuse, improper voltage, or unauthorized modification. Support will respond with an RMA number and shipping instructions if service is required. Keep your original packaging for safe transit — damage during shipping without proper packaging is not covered.
