The optional Analog Output Module (slot C15) provides component 
analog monitor outputs for M/E 2 program and switched preview. These 
outputs are designed for monitor use only and should not be used as on air 
outputs. 

There are two DAC Mezzanine boards on the Analog Output Module; one 
providing the Program analog output and the other, the Preview analog 
output. There are ten Color Difference or RGB formats to choose from as 
the analog output. Output format is determined by the customer by setting 
jumpers on the Analog Output Module and the mezzanine boards. Gain 
adjustments must also be made for accurate output levels. 

Analog Output Modules leave the factory set at RGB .700V, No Setup, and 
narrow RP125 blanking. To change to a different standard, perform the 
following steps:

1. Remove the Analog Output Module from the rear Signal Processor 

Frame, and place it on a flat, static-free surface.

2. Locate jumper J17, on the right hand side of the Analog Output Module 

immediately below TP7. Set the jumper setting to the desired blanking 
width of the converted video output. When set to RS-170 (wide 
blanking), blanking edges are placed as in the RS-170 specifications for 
60 Hz systems or for the CCIR 470-2 recommendation for 50 Hz 
systems. When it is set to RP-125, blanking is active from end of active 
video (EAV) to start of active video (SAV) data words, inclusive, as 
described in SMPTE recommended practice RP-125.

3. Locate jumper J16 on the Analog Output Module, and select the 

appropriate Setup (54 mV) or No Setup setting for your system’s 
desired analog outputs. Note that this setting is common to both 
program and preview outputs. Whatever is chosen for one applies to 
both.
