Topaz Router
Revision 2.0 Page 13
3.4. ANALOG VIDEO (AV)
The video inputs are terminated in 75Ω and DC coupled, enabling it to handle composite or component
signals. The output amplifiers are adjustment-free with a bandwidth to over 100MHz.
Vertical interval switching is referenced to the Sync Input and complies with SMPTE RP-168.
This product can also route AES unbalanced audio signals.
3.5. ANALOG AUDIO (AA)
The inputs are electronically balanced to provide a high common mode rejection over a wide frequency
range. The input connectors are two D50 multi-way types and outputs are a single D15. The output
stages are balanced and the insertion gain is so accurately maintained that no adjustment is required. A
jumper link for each output is provided to correct the gain when driving into 600Ω loads. If it is necessary
to drive unbalanced loads then just one of the output lines and 0V are used, resulting in a 6dB drop in
level.
3.6. AES/EBU DIGITAL AUDIO (DA)
3.6.1. Balanced (D50)
Not available yet.
3.6.2. Un-Balanced (BNC)
For applications using the SMPTE 276M 75Ω AES3-ID coaxial interface a standard video router can be
used. Contact the factory for more details about this application.
