Elipson INFINITE A1000: A High-Fidelity Power Amplifier at the Cutting Edge of Technology

The Elipson INFINITE A1000 is a mono power amplifier designed to deliver exceptional performance in high-end home theater and hi-fi setups. This Class D model, equipped with advanced DSP, pushes the boundaries of power and sound customization for discerning audio enthusiasts.

Massive Power for Your Bass

The INFINITE A1000 delivers an impressive 1000 W of power at 4 ohms, making it an ideal choice for driving one or more passive subwoofers, particularly the Elipson Infinite S12 in-wall models. This substantial power reserve ensures deep, powerful, and perfectly controlled bass, even in large rooms or during high-volume listening sessions.

The Class D amplification technology used in the INFINITE A1000 ensures optimal energy efficiency, minimizing heat production and allowing for a compact design despite its high power output. The integrated DSP (Digital Signal Processor) handles large amounts of data simultaneously, offering advanced sound processing capabilities.

Flexible Connectivity for Any Setup

This mono amplifier stands out for its versatility in terms of connectivity. It features multiple inputs to adapt to any possible configuration:

• A stereo XLR input for professional, balanced connections
• Two stereo RCA inputs for compatibility with most consumer audio sources
• A high-level input with screw terminals for easy integration with amplifiers lacking dedicated subwoofer outputs

This variety of connections allows the INFINITE A1000 to seamlessly integrate into any audio system, whether it’s a complex home theater setup or an audiophile hi-fi system.

Precise Frequency Response Control

One of the most remarkable features of the INFINITE A1000 is its adjustable low-pass filter, offering a wide adjustment range from 40 to 200 Hz. This flexibility allows for precise tuning of the subwoofer’s cutoff frequency to match the room’s acoustics and the characteristics of the main speakers.

Users can also choose from several attenuation slopes, ranging from -12 to -48 dB per octave, in 6 dB increments. This advanced functionality ensures a perfectly smooth transition between the subwoofer and the main speakers, eliminating any risk of overlap or gaps in the system’s frequency response.

Advanced Sound Customization

The INFINITE A1000 goes beyond basic settings by offering sophisticated sound customization tools. Seven predefined EQ profiles are available to quickly adapt the sound to user preferences or the room’s acoustic characteristics.

For the most demanding audiophiles, a 9-band parametric equalizer covering frequencies from 20 Hz to 125 Hz allows for fine-tuning of the subwoofer’s response. With an adjustment range of -6 to +3 dB for each band, users can precisely correct room acoustic anomalies or tailor the response curve to their personal taste.

Perfect Integration into Multichannel Systems

The INFINITE A1000 integrates seamlessly into home theater setups thanks to its LFE (Low Frequency Effects) mode. In this mode, only the subsonic filter remains active, leaving the AV amplifier to manage the high-frequency cutoff. This feature ensures optimal coherence between the subwoofer and the main speakers in a multichannel system.

The adjustable electrical phase, ranging from 0 to 315° in 45° increments, allows for precise alignment of the subwoofer’s phase with that of the main speakers, ensuring perfect temporal and spatial coherence of the bass in the listening room.

Intelligent Protection for Peace of Mind

The INFINITE A1000 includes several features designed to protect both the amplifier and the connected subwoofer. A subsonic high-pass filter, adjustable to 20 or 40 Hz, limits excessive cone excursion, preventing potential mechanical damage.

An auto-standby system, configurable from 5 to 30 minutes in 5-minute increments, saves energy by putting the amplifier into standby mode when no signal is detected. The standby power consumption, below 0.5 W, reflects the attention given to energy efficiency.

Elegant and Functional Design

Despite its impressive power, the INFINITE A1000 maintains reasonable dimensions (425 x 89 x 368 mm), making it easy to integrate into an audio cabinet. Its weight of 12.5 kg reflects the quality of its construction and components.

The sleek and elegant front panel blends harmoniously into any interior, while the included remote control allows for easy adjustment of various parameters from the listening position.
