The Akro series is Avante Audio's flagship professional line array system, designed for medium to large-scale live events, touring productions, and permanent installations. The system centers on the ATL328 3-way active module with Milan™ certified network audio and German-engineered DSP, paired with the ATS218 dual 18-inch subwoofer. Target users include touring production companies, rental houses, large houses of worship, and AV integrators requiring broadcast-grade audio networking and scalable, high-SPL coverage.

For small to medium venues (500–1,000 capacity), a minimum of 4 ATL328 modules per side with 1–2 ATS218 subwoofers provides adequate coverage and headroom. Medium to large venues (1,000–3,000 capacity) typically require 6–8 ATL328 modules per side with 2–4 ATS218 subs. For large outdoor events or arenas exceeding 3,000 capacity, 8–12 modules per side with a distributed sub array is recommended. Always account for throw distance, venue geometry, and required SPL when finalizing your configuration.

The Akro series is a full-scale line array with Milan™ network audio, 132 dB peak SPL per ATL328 module, and a 3-way coaxial design optimized for large venues and touring. Imperio Pro is a compact mini line array with 5-inch drivers and IDVAT HF technology, designed for fast deployment in small to medium venues. Choose Akro for large-scale events, critical listening applications, or when AVB/Milan networking is required. Choose Imperio Pro for corporate events, smaller touring acts, houses of worship, or applications prioritizing portability and rapid setup.

The ATS218 is designed to extend the ATL328's low-frequency response down to 35 Hz. For time alignment, measure the physical offset between the sub array and main array positions, then apply corresponding delay to whichever system is closer to the audience. The ATL328 crosses over internally at 600 Hz on the low end; set the ATS218's DSP high-pass filter to complement this and avoid overlap. For optimal coupling, ground-stack or fly subs in pairs and maintain phase coherence using the onboard DSP polarity controls.

The Akro system uses the AFB328 flybar as the primary rigging frame, rated for flying full arrays of ATL328 modules. The AXB328 extension lifting bar attaches to the top of the array for connection to the flybar and provides splay angle adjustment. Always verify load ratings against your total array weight including cables, and consult the Avante rigging manual for maximum module counts at specific splay angles. All rigging must be performed by qualified personnel following local safety regulations and load certification requirements.

The ATS218 supports standard broadside arrays and cardioid configurations. For cardioid mode, position one sub facing rearward with polarity inverted and apply appropriate delay via the onboard DSP to cancel rear energy and increase front-to-back ratio. End-fire arrays are also achievable using multiple units with staggered delay. Ground-stacked pairs in standard configuration provide maximum LF output for front-facing coverage.

Imperio Pro is Avante Audio's compact mini line array system, engineered for small to medium venues requiring professional-grade audio with rapid deployment. The system features the IMP205 active module with dual 5-inch neodymium drivers, IDVAT HF technology, and 32-bit DSP with FIR filters. It pairs with either the IMP118 18-inch subwoofer or Sub210 dual 10-inch sub. Ideal applications include corporate AV, houses of worship under 1,000 seats, touring singer-songwriters, DJs, and rental inventory requiring versatility and fast turnarounds.

While both are Avante line array products, Akro and Imperio Pro are designed as separate systems with different driver configurations, voicing, and DSP architectures. Combining them in the same coverage zone is not recommended due to tonal and phase differences. However, you can deploy them in separate zones—for example, Akro as the main PA and Imperio Pro as delay fills or balcony coverage—provided each zone is time-aligned and level-matched independently at the system processor or console.

Imperio Pro represents a significant upgrade over the original Imperio series. Key improvements include increased amplifier power (440W vs 240W on the original), neodymium magnets on the 5-inch drivers (replacing ferrite in the original), the addition of IDVAT (Inverted Dome Vertical Array Technology) for tighter HF pattern control, upgraded 32-bit DSP with FIR digital filters for improved phase coherence, IP-rated locking power connectors for reliable daisy-chaining, and selectable system configurations via onboard controls. The IMP118 subwoofer adds a DSP-controlled end-fire mode not available in the original lineup. These changes address professional touring and rental requirements for repeatability and advanced system tuning.

A standard Imperio Pro system consists of 2–4 IMP205 modules per side flown or ground-stacked on the IMP118 18-inch subwoofer. The IMP118 provides low-frequency extension down to 32 Hz (-10 dB) and includes selectable crossover points from 60–160 Hz to match the IMP205's response. For stereo applications, deploy a pair of IMP118 subs with 2–4 IMP205 modules on each side. The IGS205 ground stack bar allows secure mounting of IMP205 columns directly onto the IMP118 for fast setup.

Power linking capacity depends on mains voltage. At 120V, you can daisy-chain 3–4 IMP205 modules on a single circuit. At 230V, the system supports 4–6 IMP205 units in a power-linked chain. Always verify your circuit capacity (typically 15A or 20A at 120V; 10A or 16A at 230V) before deploying multiple units on a single run. The IP-rated locking power connectors ensure secure connections during touring and rental applications.

The Sub210 (dual 10-inch, 700W RMS) is optimized for applications where portability and compact footprint outweigh deep bass extension—such as small corporate events, acoustic performances, or DJ applications where sub-bass below 40 Hz is not critical. The IMP118 (18-inch, with response to 32 Hz) is preferred for live music, touring bands, or any application requiring authoritative low-frequency impact.

The IFB205 flybar is engineered to rig up to 16 IMP205 modules in a flown array configuration, enabling scalable deployments for medium-sized venues and touring productions. The flybar provides adjustable splay angles between modules for coverage optimization. Always verify the total suspended weight against venue rigging points and local safety regulations. Use certified rigging hardware and ensure installation is performed by qualified riggers. The IMP-LINKPIN4 link pins are required to secure modules to the flybar and to each other.

The IMP205 features 32-bit DSP with selectable system configurations accessible via rear-panel controls. These include array voicing presets optimized for different module counts (e.g., 2-box, 4-box, 8-box arrays), which adjust crossover, EQ, and limiting parameters for consistent tonal balance across deployment sizes. Additionally, the IMP205 offers selectable input gain sensitivity to match various console output levels. FIR digital filters provide linear-phase crossover performance for improved coherence across the frequency range.

Both models share the same core hardware: an 8-inch neodymium subwoofer base unit with two column speaker arrays, 250W RMS sub amplification, and multiple input options including dual XLR/TRS combo jacks. The only difference is that the AS8 ACDC includes an onboard battery for untethered AC/DC operation. Choose the AS8 for fixed-power applications; choose AS8 ACDC for outdoor events, mobile DJs, or locations without convenient AC access.

The IMP205 offers selectable input gain via rear-panel controls with adjustable positions at -3, 0, +3, and +6 dB, allowing operators to match the module's input stage to different console output levels. Proper gain staging at the speaker input ensures optimal signal-to-noise ratio and headroom utilization without premature limiting.

The IMP118 subwoofer includes DSP-controlled cardioid mode for rejecting low-frequency energy behind the sub array, reducing stage wash and improving front-of-house clarity. End-fire mode is achievable using multiple IMP118 units with staggered delay settings to create a forward-focused LF pattern. Access these modes via the rear-panel DSP controls. Crossover frequency is selectable from 60–160 Hz to integrate with IMP205 arrays or other tops. These features enable professional-grade LF management typically found only in larger-format systems.

IDVAT (Inverted Dome Vertical Array Technology) is the high-frequency driver configuration used in the IMP205 module. It features six 1.75-inch inverted dome drivers arranged vertically to create a coherent, tightly controlled HF wavefront. This design improves vertical pattern control compared to conventional compression drivers, reducing ceiling and floor reflections in reverberant spaces while maintaining consistent coverage across the listening area. IDVAT is a key differentiator enabling the Imperio Pro's intelligibility in challenging acoustic environments.

Use XLR or TRS inputs for any professional application requiring consistent, low-latency audio—live microphones, mixing consoles, DJ controllers, or playback devices. XLR provides balanced signal with superior noise rejection. Bluetooth input is suitable for background music, walk-in/walk-out playlists, or applications where convenience outweighs critical monitoring requirements. Bluetooth introduces approximately 40–200ms of latency depending on codec, making it unsuitable for live performance monitoring or speech requiring lip-sync accuracy with video.

The Imperio Pro ecosystem includes the IMP211 adjustable speaker pole for mounting IMP205 arrays on subwoofers or stands, the IFB205 flybar for rigging up to 16 IMP205 modules, the IGS205 ground stack bar for mounting IMP205 arrays directly on the IMP118 subwoofer, IMP-LINKPIN4 link pins for securing modules, and the IMC118 caster board for wheeling the IMP118 sub. A flybar LG (large) and white versions of select accessories are also available for installations requiring aesthetic matching.

The AS8 and AS8 ACDC column PA systems include a carry bag for the column speaker elements as standard. Pull-over covers are available for the Achromic series: CVRA10, CVRA12, and CVRA15. For Imperio Pro, the IMC118 caster board adds transport convenience for the IMP118 subwoofer. Padded covers and flight cases for specific models vary by region and may be available through authorized Avante dealers.
