MC3.2

Digital Audio & Video Master Clock
Generates highly accurate reference clock signals for synchronizing professional digital audio and SD/HD video equipment.

Three Clock Generators in One
Combines Word Clock, SD video sync, and HD video sync generation in a single unit for complete studio synchronization.

Ultra-Low Jitter Clock Generation
Provides exceptionally clean clock signals that improve synchronization accuracy and enhance overall audio performance.

Studio-Wide Clock Distribution
Supplies stable clock signals to multiple digital devices from a single centralized timing source.

Multiple Word Clock Frequencies
Generates a wide range of standard Word Clock frequencies to support virtually any professional digital audio workflow.

Independent Clock Rate Outputs
Allows different output groups to operate at different clock rates simultaneously while remaining synchronized to the same master reference.

Word Clock Multipliers
Supports multiple clock multiplication modes, including Super Clock compatibility for legacy Pro Tools® systems.

SD Video Sync Generation
Produces professional SD video reference signals for PAL and NTSC production environments.

HD Tri-Level Sync Generation
Generates HD tri-level sync signals for modern high-definition video production and broadcast systems.

Multiple HD Video Formats
Supports common HD formats including 720p, 1080i, and 1080p with multiple frame rate options.

Audio and Video Phase Synchronization
Keeps audio clocks and video reference signals phase-aligned from a common timing source for reliable A/V synchronization.

AES/EBU & S/PDIF Clock Outputs
Provides synchronized AES/EBU and S/PDIF blank-frame reference signals alongside Word Clock outputs.

Film & Broadcast Pull Factors
Supports common pull-up and pull-down rates for seamless synchronization between film, video, and audio production standards.

AES11 Grade 1 Accuracy
Delivers broadcast-grade timing accuracy that complies with AES11 Grade 1 synchronization standards.

Improved Audio Quality
Helps reduce jitter-related distortion and can improve the performance of connected AD/DA converters and digital audio systems.

Eliminates Clicks & Pops
Maintains stable synchronization across connected devices to prevent digital audio errors during recording and playback.

Simple Front Panel Operation
Intuitive controls allow quick selection of video standards, frame rates, clock frequencies, and output settings.

Automatic Settings Memory
Retains all user settings after power is removed, allowing immediate return to the previous configuration.

Compact Rack Design
Half-width enclosure saves rack space while fitting easily into professional studio installations.

Universal Power Supply
Built-in international power supply supports worldwide operation without external voltage selection.
