Sescom A/V Lip-Sync Corrector - Simple Audio Delay Control

In this review the Sescom A/V Lip-Sync Corrector is evaluated for anyone who needs fast, reliable alignment between stereo audio and video. The bottom line: it is a compact, no-frills tool that corrects audio-playback leading video by inserting a selectable delay up to 300ms, making it a practical choice for installers, home theater hobbyists, and AV technicians who route audio and video through different paths. The unit is straightforward to set, focused on function rather than features, and delivers clear, usable synchronization when sources or signal chains introduce audible lip-sync errors.

Key Features

• Adjustable Delay: Manual control lets the user set audio delay increments from 0 to 300ms to align sound with picture precisely.
• Stereo L/R I/O: Dedicated left and right analog inputs and outputs preserve stereo channels when correcting sync between devices.
• Compact Form Factor: A small footprint makes it easy to add to existing racks or AV closets without taking much space.
• Simple Operation: The device focuses on a single job with an intuitive control scheme so users can correct sync without complex menus.
• Compatibility with Mixed Paths: Designed to resolve mismatches when audio travels over analog lines and video over digital/HDMI chains.

Who It's For

The Sescom corrector is best for AV installers, streamers, and homeowners who experience audible lag when video goes through distribution amps or set top boxes while audio runs separately to amplifiers or sound bars. It is especially useful when PC audio outputs or multi-room setups create sync drift that simple display lip-sync adjustments cannot fix.

It is less suitable for users who need automatic, per-channel digital processing, or for those who require HDMI-embedded audio correction - this unit is an analog L/R delay box meant for direct stereo lines rather than an all-in-one digital matrix processor.

Pros & Cons

Pros

• Effective at eliminating audible lip-sync errors for stereo sources when set correctly.
• Easy manual adjustments make it quick to find the right delay without menus.
• Compact and unobtrusive, fitting easily into existing AV setups.
• Good value for a single-purpose tool that addresses a common synchronization problem.

Cons

• Delay increments are manual and capped at 300ms, so very specific sub-millisecond tuning or automatic correction is not available.
• Input quality can vary with source equipment, so some setups may require additional signal conditioning for optimal results.

Our Verdict

The Sescom A/V Lip-Sync Corrector is a focused, affordable solution for anyone battling audible lead or lag between audio and video in mixed-signal installations. It is not a digital matrix or HDMI embedder, but for stereo analog delay correction up to 300ms it is effective, easy to use, and represents solid value for installers and hobbyists who need predictable, manual synchronization.

Frequently Asked Questions

Can this unit fix sync when audio is sent to a separate amplifier?
Yes. It is designed to add delay to the analog audio path so the sound lines up with video sent over HDMI or other digital routes.

How fine is the delay adjustment?
The delay is set in defined increments up to 300ms with manual control; it does not offer automatic or sub-millisecond tuning.

Is this for HDMI audio correction?
No. This corrector works on stereo L/R analog lines and is not an HDMI-embedded audio processor.
