Professional HDMI Distribution Amplifiers
VigilLink's HDMI Distribution Amplifier range covers every technology tier the modern professional AV market requires: HDMI 2.1 at 48Gbps for 8K@60Hz and 4K@120Hz source distribution, HDMI 2.0 at 18Gbps for standard 4K@60Hz multi-display installations, HDBaseT-integrated models that extend and distribute simultaneously over a single Cat6 cable to 150 meters, audio de-embedding variants that split off analog and digital audio from the HDMI path, and VLink CAT extender models that distribute HDMI signals across existing Cat cable infrastructure without dedicated HDBaseT receivers.
Whether you're distributing 4K60 presentation content across a multi-screen boardroom, splitting a 4K@120Hz gaming source to multiple monitors, feeding eight HDBaseT drops from a single source in a large venue, or routing audio separately from video in a house-of-worship AV system, VigilLink provides a purpose-engineered distribution amplifier for the task — backed by a 6-year warranty and full professional AV integration support.

Choosing the Right HDMI Distribution Amplifier
8K 48Gbps HDMI 2.1 (VLSP-12H21S / VLSP-12H21SA / VLSP-14H21S / VLSP-14H21SA / VLSP-18H21S / VLSP-22H21): 48Gbps bandwidth supporting 8K@60Hz, 4K@120Hz, VRR, ALLM, and Dolby Vision. Available in 1x2, 1x4, and 1x8 configurations, plus the VLSP-22H21 2x2 dual-input variant. SA models add audio de-embedding. Choose this family for any installation involving PlayStation 5, Xbox Series X, 8K sources, or high-frame-rate displays.
4K 18Gbps HDMI 2.0 (VLSP-12H20 / VLSP-14H20 / VLSP-14H20D / VLSP-16H20 / VLSP-18H20): Standard 4K@60Hz distribution at 18Gbps in 1x2, 1x4, 1x8, and 1x16 configurations. The VLSP-14H20D adds an integrated scaler to simultaneously feed 4K and 1080p displays from a single unit. Choose this family for presentation systems, digital signage, and corporate AV where 4K@60Hz is the maximum source requirement.
4K 18Gbps over HDBaseT 150m (VLSP-12HT150 / VLSP-14HT150 / VLSP-18HT150): Combines 4K@60Hz HDMI 2.0 distribution with HDBaseT transmission to 150 meters per output over a single Cat6 cable — no separate receiver required at each display. Choose for large venues, campus AV, and any installation where display locations exceed standard HDMI cable distances.
HDMI 2.0 with Audio De-Embed & Downscale (VLSP-AS12H20 / VLSP-AS14H20): Distributes 4K@60Hz video to all HDMI outputs while simultaneously extracting analog stereo, optical, and coaxial S/PDIF audio. Choose when an HDMI source must feed both displays and a separate room audio system that lacks an HDMI input.
VLink HDMI over CAT (VLSP-12CTH14 / VLSP-12CTH20 / VLSP-14CTH14 / VLSP-14CTH20 / VLSP-18CTH14 / VLSP-18CTH20): Distributes HDMI over Cat5e/6 at up to 70m (HDMI 1.4) or 60m (HDMI 2.0) in 1x2, 1x4, and 1x8 configurations. Choose when existing Cat cabling is already installed to display locations and HDBaseT distances are not required.
Ideal Applications
Corporate AV & Multi-Display Presentation
HDMI 2.0 distribution amplifiers (VLSP-14H20, VLSP-18H20) feed identical 4K@60Hz to every display in a conference room or training facility from a single source. For rooms with a separate audio system, the VLSP-AS12H20 or VLSP-AS14H20 simultaneously extracts audio for the room amplifier while distributing video.
Digital Signage & Retail Display Networks
The VLSP-16H20 (1x16) and VLSP-18H20 (1x8) drive high-count signage arrays from a single rack unit. HDBaseT models (VLSP-14HT150, VLSP-18HT150) extend signal to displays up to 150 meters from the head end, eliminating local media players at each screen. VLink CAT models serve installations where existing Cat cabling already runs to display locations.
Esports, Gaming & Broadcast Monitoring
The VLSP-14H21S and VLSP-18H21S distribute full 48Gbps bandwidth to multiple gaming monitors and capture devices simultaneously, preserving 4K@120Hz, VRR, and Dolby Vision from PlayStation 5, Xbox Series X, and gaming PC sources. The VLSP-14H21SA adds audio de-embedding for simultaneous feed to a streaming audio mixer.
House of Worship & Large Venue AV
HDBaseT distribution amplifiers (VLSP-18HT150) feed main screens, overflow rooms, lobby monitors, and streaming encoder inputs from a single rack unit over Cat6 at up to 150 meters per output. Audio de-embedding variants simultaneously feed the installed sound system from the same HDMI source.
Higher Education & Lecture Capture
HDMI 2.0 distribution amplifiers deliver consistent 4K@60Hz to projection, rear monitors, and lecture capture systems with full HDCP compliance. The VLSP-14H20D scaler variant supports mixed-resolution environments where some displays are 1080p and others are native 4K. VLink CAT models serve buildings where Cat cable runs to displays are already in place.
Frequently Asked Questions
What is the difference between an HDMI distribution amplifier and a passive HDMI splitter?
A distribution amplifier uses active signal regeneration at every output to maintain full bandwidth, HDCP compliance, and signal integrity. A passive splitter divides the signal electrically, causing quality loss, HDCP handshake failures, and unreliable operation with 4K or HDR content. Active distribution amplifiers are required for any professional AV installation.
What is the difference between HDMI 2.0 and HDMI 2.1 distribution amplifiers?
HDMI 2.0 models support 18Gbps for 4K@60Hz. HDMI 2.1 models support 48Gbps for 8K@60Hz, 4K@120Hz, VRR, and ALLM. If your source is a PlayStation 5, Xbox Series X, or 8K system, an HDMI 2.1 amplifier is required. HDMI 2.1 models are backward compatible with HDMI 2.0 sources and displays.
How many outputs do I need?
Choose output count based on total display and destination count — including recording systems and streaming encoders. VigilLink models are available in 1x2, 1x4, 1x8, and 1x16 configurations. Selecting one tier above your current count is recommended for future-proofing.
What cable types and maximum distances are supported?
Standard HDMI models support cable runs to approximately 10–15 meters. HDBaseT models (VLSP-12HT150 through VLSP-18HT150) extend to 150 meters over Cat6/6A. VLink CAT models reach 60–70 meters over Cat5e/6. Distances beyond 150 meters require fiber extender solutions.
Do VigilLink distribution amplifiers support HDCP 2.3 and HDR?
Yes. All VLSP-series models support HDCP 2.3, HDR10, HDR10+, Dolby Vision, and HLG passthrough. Each output manages its own HDCP handshake independently, so a non-HDCP display on one output does not affect other outputs.
Can I send different resolutions to different displays?
Standard models output the same signal to all ports. The VLSP-14H20D is the exception — its integrated scaler simultaneously outputs native 4K to HDMI outputs and 1080p on the scaler output. Per-output resolution control across all ports requires a matrix switcher with per-output scaling.
What is an HDBaseT distribution amplifier and when do I need one?
An HDBaseT distribution amplifier combines splitting with long-distance HDBaseT transmission over a single Cat6 cable to 150 meters, replacing both a DA and separate extenders with one device. Use when display locations are spread across a large venue and direct HDMI cable runs are impractical.
What is audio de-embedding in a distribution amplifier?
Audio de-embedding extracts the HDMI audio stream as a separate analog or digital output — L/R stereo, optical TOSLINK, or coaxial S/PDIF — while passing full video to all display outputs. It is needed when a source must simultaneously feed displays and a room audio system without an HDMI input. Available on the VLSP-12H21SA, VLSP-14H21SA, VLSP-AS12H20, and VLSP-AS14H20.
