The ATL328 is a 3-way active dual 8-inch line array module delivering 900W RMS (1800W peak) via Class D amplification. It achieves a peak SPL of 132 dB per unit with a frequency response of 70 Hz to 20 kHz. The coaxial MF/HF section uses a 4-inch midrange and 2.55-inch neodymium HF driver on a custom waveguide, crossed over at 600 Hz and 3.5 kHz. Horizontal directivity is 110°.

For small to medium venues (200–500 capacity), 4–6 ATL328 modules per side typically provide adequate coverage. Medium to large venues (500–2000 capacity) generally require 8–12 modules per side. Large touring productions may deploy arrays of 12–24 modules per side depending on throw distance requirements and desired SPL. The AFB328 flybar is TÜV-certified to support up to 24 ATL328 units in a single flown array.

Milan certification means the ATL328 supports deterministic, low-latency network audio transport over AVB/TSN (Audio Video Bridging / Time-Sensitive Networking) Ethernet infrastructure. Milan ensures plug-and-play interoperability with other Milan-certified devices from any manufacturer. The protocol supports redundant network paths and guaranteed bandwidth allocation. Dante integration is possible via a Milan-to-Dante bridge device.

The ATL328 features power linking between units, allowing daisy-chaining of AC power through the array. The exact number of units per circuit depends on your local AC voltage and circuit capacity. On a 20A/240V circuit, multiple units can be linked; consult the ATL328 user manual for specific power draw calculations based on your electrical infrastructure. Always verify total current draw does not exceed circuit breaker ratings.

The ATL328 is primarily designed for vertical line array deployment using the AFB328 flybar or ground stack configurations with the ATC328 transport cart and ASB328 stabilizer bars. Vertical arrays leverage the 110° horizontal dispersion while the vertical coverage narrows as more modules are added, providing controlled throw. Horizontal configurations are not standard for line array deployment but may be considered for specialty applications with appropriate rigging.

The ATS218 is a dual 18-inch active subwoofer delivering 2400W RMS (4800W peak) via Class D amplification. Frequency response extends from 35 Hz to 200 Hz with a peak SPL of 142 dB. Each 18-inch driver features a 4-inch voice coil. The unit includes an auto-switching power supply (100V–240V, 50/60Hz) and German-engineered DSP with Milan certification for network audio integration.

A common starting ratio is 1 ATS218 subwoofer per 4–6 ATL328 modules, depending on music genre and desired low-frequency impact. For medium events with 8–12 ATL328s per side, 2–4 ATS218 units total provides balanced LF extension. Large touring productions with 16–24 ATL328s per side may require 6–12 ATS218 units in ground-stacked or flown sub arrays. Adjust ratios based on content type—bass-heavy genres may warrant additional subs.

Yes, the ATS218's onboard DSP supports configurations for cardioid and end-fire sub array deployments. Cardioid arrays use front-facing and rear-facing subs with delay and polarity adjustments to cancel rear energy, reducing stage bleed. End-fire arrays stack subs front-to-back with progressive delay to increase forward throw. The German-engineered DSP provides the delay, phase, and filter controls necessary for these configurations.

Time-align the ATS218 subwoofers to the ATL328 array by measuring the physical offset between sub and main array positions. Use the ATS218's onboard DSP delay function to compensate for path length differences—typically 1ms per foot (3.3ms per meter) of offset. Set the ATS218 crossover frequency to integrate with the ATL328's 70 Hz low-frequency limit. Use measurement software to verify phase coherence at the crossover region.

The IMP205 delivers 440W RMS and features dual 5-inch neodymium LF drivers paired with 6x 1.75-inch IDVAT (Inverted Dome Vertical Array Technology) HF drivers. The onboard 32-bit DSP includes FIR digital filters for precise phase and frequency response control. Selectable system configurations and gain input sensitivity allow optimization for various deployment scenarios. IP-locking power connectors enable secure daisy-chain power linking.

For a 500-seat venue, 4–6 IMP205 modules per side typically provides adequate SPL and coverage for speech and moderate-level music reinforcement. For higher-SPL applications like live bands or DJ events, consider 6–8 modules per side. Pair with IMP118 or Sub210 subwoofers for full-range LF extension below the IMP205's native response. The IFB205 flybar supports arrays up to 16 IMP205 modules for larger configurations.

IDVAT (Inverted Dome Vertical Array Technology) refers to the IMP205's six 1.75-inch high-frequency drivers arranged in a vertical line with inverted dome diaphragms. This configuration provides controlled vertical dispersion while maintaining wide horizontal coverage, characteristic of line array behavior. The inverted dome geometry improves off-axis frequency response consistency and reduces comb filtering compared to conventional dome tweeters in array configurations.

The IMP205's 32-bit DSP offers selectable system configurations via a rear-panel selector switch. These presets optimize the module's frequency response, limiting, and crossover settings for different array sizes and deployment scenarios (e.g., small arrays, large arrays, standalone use). Additionally, selectable gain input sensitivity allows matching to various console output levels. Refer to the user manual for specific preset descriptions and recommended applications.

The IMP118 is a professional 18-inch active subwoofer with a 4-inch (100mm) voice coil in a bass-reflex enclosure. Frequency response is 32 Hz–130 Hz (–10dB) or 38 Hz–130 Hz (–3dB). Onboard DSP provides delay, selectable crossover frequencies (60/70/80/90/100/120 Hz), and cardioid mode for directional bass control. The unit is designed to pair with IMP205 line array modules for full-range Imperio Pro systems.

The IMP118 features a selectable cardioid setting accessible via the rear-panel DSP controls. Cardioid mode applies internal delay and phase processing to reduce rear-firing low-frequency energy, minimizing stage bleed and improving front-of-house clarity. For optimal cardioid performance, position the IMP118 with its rear facing the stage. The unit also supports end-fire configurations when multiple subs are deployed with appropriate delay offsets.

Set the IMP118's crossover frequency to complement the IMP205's low-frequency roll-off—typically 80–100 Hz provides smooth integration. Use the IMP118's onboard delay to time-align the subwoofer to the IMP205 array based on physical placement offset. Both units feature 32-bit DSP, allowing precise matching. Verify phase coherence at the crossover point using measurement software, and adjust polarity if needed to ensure summing rather than cancellation.

A single ATL328 module achieves 132 dB peak SPL. When coupling multiple modules in a vertical array, SPL increases by approximately 3 dB for each doubling of array elements (e.g., 2 units ≈ 135 dB, 4 units ≈ 138 dB theoretical peak). Actual system SPL depends on array configuration, splay angles, and environmental factors. The German-engineered DSP includes multiband limiting to protect drivers while maximizing output.

The AFB328 flybar is required to fly ATL328 arrays and is TÜV-certified to support up to 24 ATL328 modules in a single flown array. The flybar serves as both the primary rigging point and a ground stack base when not flying. For ground-stacked deployments, the ATC328 transport cart doubles as a ground-support platform when used with ASB328 stabilizer bars. Always follow local rigging codes and use certified rigging personnel.

The ATL328 uses a 3-way active crossover architecture with crossover points at 600 Hz and 3.5 kHz. The dual 8-inch neodymium woofers handle LF below 600 Hz, the coaxial 4-inch midrange covers 600 Hz to 3.5 kHz, and the 2.55-inch neodymium HF driver on a custom waveguide handles frequencies above 3.5 kHz. Each driver section has its own dedicated amplifier channel for optimized power delivery and DSP control.

The ADB218 transport dolly board is designed specifically for the ATS218 and can be positioned over the grill or under the cabinet when horizontal. One dolly board can transport up to three ATS218 cabinets stacked together. The dolly boards are stackable when not in use for space-efficient storage. Heavy-duty casters provide smooth rolling on venue floors and loading docks.

The Sub210 is a dual 10-inch subwoofer delivering 700W RMS, designed for compact Imperio Pro systems. Compared to the IMP118 (single 18-inch, deeper extension to 32 Hz), the Sub210 offers a more portable form factor with reduced low-frequency extension, suitable for smaller venues. Choose IMP118 for maximum LF output and extension; Sub210 for portability and mid-size deployments.

The IFB205 flybar is designed for flying IMP205 arrays and supports up to 16 IMP205 modules in a single flown array. A flybar LG (large) variant is also available, including a white version for installations requiring aesthetic matching. For ground-stacked configurations, the IGS205 ground stack bar provides secure module connection. All rigging should be performed by certified personnel following local safety codes.

The IMP205 features XLR input and output connectors for signal pass-through to additional modules. IP-locking power connectors enable secure AC daisy-chaining between units. This allows building complete arrays with a single signal feed and power run to the first unit.

The AS8 ACDC includes a 28.8V 5000mAh (144Wh) lithium-ion battery. Battery life varies based on output level—at moderate volumes, expect several hours of continuous operation. A battery life indicator on the unit displays remaining charge. Recharge time depends on charge state and ambient conditions; the unit can operate on AC power while charging. Consult the user manual for detailed battery specifications and charging guidelines.

All three Achromic series speakers (A10X, A12X, A15X) feature dual-position pole mounting at 0 degrees and 7.5 degrees of tilt. This allows aiming the speaker downward toward the audience when mounted on a standard speaker pole or subwoofer pole mount. The 7.5-degree position is particularly useful for elevated speaker positions where downward coverage is needed to reach the front rows.

The A10X, A12X, and A15X feature integrated fly points: 2 on top and 1 on the back of each enclosure. These M10 threaded points accept standard rigging hardware for permanent installation or temporary flying in houses of worship, theaters, and corporate environments. Always calculate total system weight and use appropriately rated hardware. Follow local building codes and consult certified riggers for overhead installations.

The A10X, A12X, and A15X use H-PP (High-Performance Polypropylene) molded enclosures, providing a durable, weather-resistant housing suitable for portable and installed applications. The molded design offers consistent acoustic properties and resists the wear typical of rental and touring use. A 1.2mm steel grill protects the drivers from impact damage during transport and setup.

The AVAC4 caster kit (set of 4) is designed for the Achromic A15S and A18S subwoofers, enabling easy transport across venue floors. The casters attach to the bottom of the subwoofer enclosure and can be removed for stationary use. This accessory is particularly useful for rental houses and venues requiring frequent repositioning of subwoofers.

The ATL328 features a custom waveguide for the coaxial 4-inch mid and 2.5-inch HF driver, providing 110° horizontal directivity. The waveguide design ensures consistent HF coverage across the horizontal plane while allowing vertical directivity to be controlled by the number of modules in the array. This wide horizontal coverage is ideal for venues requiring broad audience coverage from a compact line array format.

Set the A18S crossover between 80-100 Hz for pairing with the A12X, or 70-90 Hz with the A15X, depending on venue acoustics and desired low-mid impact. Apply delay to the subwoofer to time-align it with the tops based on physical placement — typically 1 ms per foot of offset between sub and top positions. Use the A18S LCD to verify settings, and apply a high-pass filter on the tops at the same crossover point to prevent LF overlap and reduce driver excursion.

The SPL110 is a professional tripod speaker stand with a maximum load capacity of 50 lbs. It is compatible with full-range speakers featuring a 35 mm pole socket, including the A10, A10X, A12, A12X, A15, and A15X. The stand is not intended for subwoofers or line array modules, which require dedicated rigging hardware or ground stack configurations.

The SPL110 is designed for 35 mm pole-mount speakers and is not the primary stand solution for Imperio Pro line array systems. Imperio Pro deployments typically use the IMP211 adjustable pole (mounted on the Sub210 subwoofer), the IMP194 pole, or the IFB205 flybar for flown configurations. SPL110 assembly involves extending the tripod base legs, locking them at full extension, then inserting and securing the telescoping pole at the desired height using the locking collar.
