SDI Dual Channel Modulator

The Contemporary Research QMOD-SDI 2 is a dual channel modulator with 2 HD-SDI inputs.  Not only does it accept SDI resolutions, the QMOD-SDI 2 can accept 3G SDI and 60/30 Hz feeds from prosumer type SDI sources. Send two HD-SDI streams over affordable coax cable, perfect for sports bars, house of worship, gyms and much more.

The QMOD-SDI 2 accepts pass-through AC-3 audio, converts stereo and PCM to stereo AC-3, can create dual-language audio for each program.  Mount in a single rack space side by side with the RK2 mount or as a single with the RK1 mount.

The QMOD-SDI 2 Includes Scaling

Full scaling is now included which allows precise formatting of digital signage and accepts 1080p video, as well as compensates for 60/30 Hz consumer source and scales all video to a set resolution.
