iFi SilentPower HDMI iSilencer

The SilentPower HDMI iSilencer is a compact active HDMI noise filter designed to reduce electrical interference and help maintain clean, stable audio and video performance. Active Noise Cancellation II (ANC2) technology targets incoming electrical noise and interference from connected AV equipment, while dedicated circuitry helps reduce jitter for improved signal timing.

The HDMI iSilencer also incorporates Transient Voltage Suppression (TVS) surge protection to help protect connected equipment from excess voltage and electrostatic discharge. Its pure-passthrough design supports HDMI 2.1 and earlier HDMI standards, including Ultra HD/HDR video up to 8K/60Hz and 4K/120Hz.

Installation is simple: connect the HDMI iSilencer to an HDMI port and connect your HDMI cable to its HDMI output. Its compact 51 × 24 × 10mm enclosure makes it easy to integrate into home theater, gaming, and other AV systems.

Active Noise Cancellation II

ANC2 technology is designed to reduce incoming electrical noise and electromagnetic interference generated by components within an AV system, helping minimize interference that can affect HDMI audio and video performance.

Jitter Reduction

Internal circuitry is designed to reduce jitter and improve signal timing at the conversion stage, with SilentPower citing improvements in areas such as image contrast and color accuracy.

HDMI 2.1 Pure Passthrough

The HDMI iSilencer maintains HDMI signal passthrough while supporting HDMI 2.1 and earlier standards, including Ultra HD/HDR video up to 8K/60Hz and 4K/120Hz.

Surge Protection

A built-in Transient Voltage Suppression system helps protect connected AV components against excess voltage and electrostatic discharge while maintaining normal HDMI operation.
