HEB550 - HD, SD 8 channel analog audio embedder with ‘TWINS’ dual channel function (3Gb/s upgradeable)
Description
The HEB550 is an HD SDI and SD SDI analog audio embedder. It is capable of inserting or appending up to 8 analog audio channels. The GEB500 has 4 analog audio inputs. The core of these modules consists of four embedder-blocks Emb_A, Emb_B, Emb_C and Emb_D and 2 delay blocks. These blocks can be used in series for a single SDI 4 group embedder with up to 1 sec of video offset delay, or in parallel for 2 individual channels with each 2 group embedders and individual 500ms offset delay in a fully separate channel TWINS function. Each block is capable of embedding 4 audio channels into one group, which gives a total of 16 audio channels (out of 8 local analog audio inputs and 16 additional inputs via the ADD-ON buss) into four (or 2x2) groups. The TWINS mode is a single command operation and controls 4 individual selection switches as can be seen in the block diagram.
In addition, four ADD-ON cards can be connected to create a routing matrix. The architecture of Emb_A to Emb_D blocks is identical. The local analog audio can be controlled to adjust Phase, Gain and delay (on the fly).

Complementary cards:
- ADC20, ADC24, DIO24, DIO48, DLA44, DLA43
* (In dual mode, or 2-SDI shuffle mode the sources need to be running on the same clock, the phase is not critical)
