Professional JackPack (XH G1 only)

While there are many situations that call for smaller, lighter HD cameras, most such products are unsuit- able for professional applications because they lack the necessary interface capability. The Canon XH G1 features a Professional JackPack with HD-SDI (SMPTE 299M) or SD-SDI (SMPTE 272M) output, Genlock input, and SMPTE Time Code in/out con- nectors. The HD-SDI output provides a 1.485Gbps 60i signal at 1920 x 1080 resolution and with

4:2:2 color sampling with embedded audio and time code. Because a single industry standard connection carries video, audio, SMPTE (LTC)

Time Code, and digital audio, cabling complexity is significantly reduced. It enables longer cable runs, improves operator mobility, and simplifies cabling. The Genlock input enables multi-camera synchronization in live-switched environments. It can accept either an SD (black burst) or HD (tri-level) sync signal when shooting HD. A switchable SMPTE input/output port accommodates time code requirements during multi-camera shoots and post-production.

Shutter Speeds

When shooting with the shutter priority auto exposure mode, the XH G1 and XH A1 provide 14 different shutter speeds ranging from 1/3 to 1/15,000 of a second. The 24F mode includes a 1/48 second setting that perfectly matches the shutter speed of a motion picture film camera. (For NTSC 60i/30F and PAL 50i/25F, there are 13 avail- able settings.)

Superior Connectivity

The XH G1 and XH A1 include a full complement of input and output ports to meet just about any interface requirement. Two XLR mic/line audio inputs accommodate professional balanced connections. Also provided are industry standard connectors, including component (HD/SD) and composite video outputs (BNC/RCA), an IEEE 1394 (Firewire) port, a LANC terminal, and a headphone jack.

Audio Recording Control

Individual audio level controls, switchable 20 dB mic attenuation, 12 dB mic gain boost, and various monitoring options provide full control over the sound as it is recorded. They even include switch- able phantom power (+48V) to eliminate the need for any external power supply with direct mic input. An external microphone holder is provided for on-camera mounting and for an optional professional shotgun microphone.
