GEB550 - 3Gb/s, HD, SD 8 channel analog audio embedder with ‘TWINS’ dual channel function
Description
The GEB550 is a 3GB/s,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).
The GEB500 can be future upgraded to GEb550. The HEB500 can be future upgraded to HEB550, GEB500 or GEB550. This allows for staged implementation of HD infrastructures and spread the cost over multiple budget years.

- Transparent for ATC time code RP188, RP196, RP215
- Locks to Tri-level, Bi-level syncs or SDI input
- Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP)
- Optional 1 or 2 fiber inputs, 1 or 2 fiber outputs or a fiber in and output (replacing 1 SDI in and output) on the I/O panel
- Optional relay bypass (BHX18 or BHX18D)
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).
