Complimentary White Glove Delivery • Expert Private Cinema Design

The StormAudio Impulsion 8 is an advanced eight-channel power amplifier combining high-output Class D amplification, native digital Audio over IP (AoIP) connectivity and integrated loudspeaker processing in a compact 2U chassis. Engineered for reference home theaters, immersive audio systems and professional studios, Impulsion 8 delivers 200 watts per channel into 8 ohms or 400 watts per channel into 4 ohms, with all eight channels driven.

Unlike conventional multichannel amplifiers, Impulsion 8 incorporates AES67/Dante-compatible digital audio inputs, onboard DSP, ESS SABRE HyperStream IV digital-to-analog conversion and full IP monitoring. This architecture allows digital audio distribution, loudspeaker management and amplification to operate within a single integrated component.

For demanding loudspeaker systems, the amplifier supports four bridged channels delivering 800 watts RMS each, with peak power capability reaching up to 1,200 watts into 4 ohms under specified conditions.

Developed using Pascal Audio UMAC Class D technology and a substantial 3,600-watt UREC power supply, Impulsion 8 offers exceptional flexibility for sophisticated private cinema installations.

Eight Channels of High-Current Class D Amplification

The Impulsion 8 delivers substantial continuous power across all eight channels, making it suitable for demanding surround sound and immersive audio systems.

In standard eight-channel operation, the amplifier provides 200 watts RMS per channel into 8 ohms and 400 watts RMS per channel into 4 ohms, measured with all channels driven at 0.1% THD+N.

Pascal Audio's UMAC Class D architecture combines high efficiency, low distortion and precise loudspeaker control. A damping factor greater than 400 supports controlled driver movement and accurate transient reproduction.

With a signal-to-noise ratio exceeding 115dB, Impulsion 8 is engineered to preserve detail across demanding movie soundtracks and multichannel music.

Four-Channel Bridged Operation

Impulsion 8 supports Bridge Tied Load (BTL) operation for installations requiring additional output power.

In bridged configuration, the amplifier delivers 800 watts RMS per channel into 8 or 4 ohms, with all four bridged channels driven.

Peak power capability can reach up to 1,200 watts into 4 ohms under the manufacturer's specified conditions.

Standard and bridged output modes can be assigned according to the loudspeaker configuration, allowing the amplifier to accommodate systems with different power requirements.

Native AES67 and Dante-Compatible Digital Audio

One of Impulsion 8's defining features is its eight-channel digital Audio over IP input, supporting AES67 and Dante-compatible network audio workflows.

Alongside its eight balanced XLR analog inputs, this connectivity allows the amplifier to receive audio directly over a compatible digital network.

Digital audio distribution can simplify system wiring, reduce the need for long analog cable runs and provide greater flexibility when designing complex private cinemas.

Impulsion 8 integrates naturally into StormAudio's networked ecosystem and compatible professional audio installations.

Integrated DSP and Loudspeaker Management

Impulsion 8 incorporates onboard digital signal processing for its AoIP signal path, providing advanced loudspeaker configuration capabilities without requiring separate external DSP hardware for those functions.

Available processing includes:

• Multi-way loudspeaker management

• Parametric equalization

• FIR filtering

• Limiting and compression

These tools allow installers to implement precise loudspeaker processing, manage active speaker configurations and optimize system performance.

Integrated DSP is particularly valuable for advanced private cinemas, active loudspeaker systems and installations requiring sophisticated signal routing.

ESS SABRE HyperStream IV DAC Technology

The Impulsion 8 uses ESS SABRE HyperStream IV digital-to-analog conversion technology, sharing a digital audio architecture with StormAudio's reference immersive processors.

This high-performance DAC platform converts incoming digital audio signals for amplification while supporting the amplifier's integrated processing capabilities.

The result is a streamlined digital signal path from a compatible networked processor to the loudspeaker outputs.

3,600-Watt UREC Power Supply

The amplifier incorporates a high-capacity Pascal Audio UREC switching power supply rated at 3,600 watts.

Designed to respond rapidly to changing electrical demands, this power supply supports substantial dynamic headroom across multiple amplifier channels.

Its universal-voltage architecture accommodates installations using 100–240V AC power.

Full IP Monitoring and Remote Management

Impulsion 8 provides comprehensive network-based monitoring for professional system integrators.

Through compatible StormAudio ISP processors, technicians can access amplifier operating information, including temperature, fan speed, power status, mute status and protection conditions.

Network configuration supports DHCP or static IP addressing, allowing integration into professionally managed AV networks.

This capability is especially valuable in private cinemas with remotely located equipment racks, where ongoing system monitoring and diagnostics can reduce service complexity.

Quiet Cooling and Compact 2U Construction

The Impulsion 8 occupies just two rack units, offering substantial power and processing capability in a compact enclosure.

Electronically controlled ventilation uses multiple thermal sensors to regulate cooling according to operating conditions.

StormAudio specifies maximum fan noise below 30dB, making the amplifier suitable for installations where low operating noise is important.

The amplifier weighs approximately 25.6 pounds, simplifying installation compared with larger multichannel amplifier designs.
