iFi Audio HDMI iSilencer 2 Active HDMI 2.1 Noise Filter with Surge Protection

The iFi Audio HDMI iSilencer 2 is a compact, active HDMI signal conditioner designed to reduce unwanted electrical interference, improve signal integrity and provide additional protection for connected home entertainment equipment. Featuring iFi's patented Active Noise Cancellation II technology, Jitter Elimination and integrated Transient Voltage Suppression, this second-generation device helps maintain clean, stable digital audio and video transmission between compatible HDMI components.

Designed for modern home theatre systems, the HDMI iSilencer 2 supports high-bandwidth HDMI 2.1 connections, including 8K Ultra HD video at 60 Hz and 4K video at 120 Hz. It also supports compatible HDR content, making it suitable for high-resolution televisions, projectors, AV receivers, processors, gaming consoles and media players without compromising supported video formats.

Approximately 20% more compact than the original HDMI iSilencer, the second-generation design features tapered sides that accommodate closely spaced HDMI connections. Its integrated HDMI male and female connectors allow straightforward inline installation, while the included 15 cm (5.9-inch) HDMI extension cable provides additional flexibility for equipment with restricted access or tightly arranged ports.

Active Noise Cancellation II Technology

The HDMI iSilencer 2 incorporates iFi's patented Active Noise Cancellation II technology to reduce unwanted electrical noise travelling through an HDMI connection.

This active filtering system is designed to counter electromagnetic and radio-frequency interference generated by connected electronic equipment. Compared with conventional noise filters, iFi specifies measured noise reduction of up to 100 times, representing more than 40 dB of attenuation under its stated measurement conditions.

Reducing interference helps maintain signal integrity throughout the connected audio/video system, particularly in installations containing multiple digital devices and switching power supplies.

Jitter Elimination Technology

Jitter refers to unwanted timing variations within digital signal transmission. The HDMI iSilencer 2 incorporates dedicated Jitter Elimination technology designed to reduce these timing irregularities and support more consistent digital signal delivery.

By addressing unwanted timing variations, the device is designed to help preserve audio and video signal accuracy. The audible or visible effect depends on the connected equipment and the level of interference present in the installation.

Integrated Surge Protection

The HDMI iSilencer 2 features integrated Transient Voltage Suppression (TVS), providing additional protection against electrical transients that may travel through an HDMI connection.

TVS technology is designed to respond to short-duration voltage spikes, including electrostatic discharge and other transient disturbances, helping reduce the risk of damage to sensitive HDMI interface electronics.

This integrated protection complements the device's signal-conditioning functions. It is not a replacement for appropriate mains surge protection or lightning protection equipment.

HDMI 2.1 with 8K and 4K Support

The HDMI iSilencer 2 supports HDMI 2.1 and remains backward compatible with earlier HDMI interface versions.

Its high-bandwidth signal path accommodates supported video resolutions up to 8K at 60 Hz and 4K at 120 Hz, making it suitable for modern high-resolution televisions, gaming systems and home theatre installations.

Compatible HDR signals are also supported, allowing the device to be integrated into systems using high-dynamic-range video content. Actual resolution and refresh-rate capabilities depend on the connected source, display, cables and equipment configuration.

Compact Second-Generation Design

The HDMI iSilencer 2 is approximately 20% smaller than its predecessor. This reduced footprint helps simplify installation behind televisions, projectors, AV receivers and other equipment where connector spacing may be limited.

Tapered side profiles allow the device to fit more easily alongside adjacent connections, while its shorter internal signal paths support the compact active filtering architecture.

Measuring only 30 x 20 x 9.3 mm (1.18 x 0.79 x 0.37 inches), the HDMI iSilencer 2 adds signal-conditioning functionality without requiring a large external enclosure.

Simple Inline HDMI Installation

The HDMI iSilencer 2 installs directly into a compatible HDMI connection between the existing HDMI cable and an AV component.

The device features an HDMI female input and HDMI male output, allowing it to connect inline without replacing the existing HDMI cable.

An included 15 cm (5.9-inch) male-to-female HDMI extension cable provides additional installation flexibility where direct connection would be difficult or place unnecessary strain on the HDMI port.

Designed for Modern Home Entertainment Systems

The HDMI iSilencer 2 can be integrated with compatible AV receivers, surround sound processors, televisions, projectors, video streamers, Blu-ray players and gaming consoles.

Its combination of active noise reduction, jitter management and transient protection provides a practical signal-conditioning option for home entertainment installations where electrical interference or signal integrity is a concern.

The device is designed to preserve supported HDMI functionality while providing filtering and protection within the existing connection.
