Operation  
Specifications, cont’d  
Equalize adjustment — This control is similar to a TV’s  
sharpness control. The equalization adjustment compensates for  
losses due to capacitance over long cable runs. The control  
adjusts the peaking, through multiple turns, between 0 and +4dB.

Video output  
Number/signal type ................... 7 composite video .... 6 amplified for distribution  
1 buffered loop-through  
Connectors .................................... 7 BNC female  
Operation — With a waveform monitor connected to the far end  
of one of the output cables, adjust the equalization so that the  
color burst ranges between -20 IRE and +20 IRE.  
Minimum/maximum levels ...... 0.4V to 2.0V p-p  
Impedance .................................... 75 ohms  
DC offset ....................................... 20mV maximum with input at 0 offset  
If no waveform monitor is available, adjust the equalization to  
restore the frequency response and achieve the best possible  
image.  
Sync  
Standards ...................................... NTSC 3.58, NTSC 4.43, PAL, SECAM  
The equalize adjustment is a 15-turn potentiometer with a soft  
mechanical stop at the high or low end. If you have reached the  
high or low end of the adjustment, the potentiometer makes a  
clicking sound as you turn it, and no change is apparent on the  
display.  
General  
Power ............................................. 100VAC to 240VAC, 50/60 Hz, 12 watts, internal,  
auto-switchable  
Temperature/humidity .............. Storage -40° to +158°F (-40° to +70°C) / 10% to  
90%, non-condensing  
The level and equalization adjustments affect all six output  
channels simultaneously and equally. For maximum effectiveness  
of the level and equalization controls, all display devices should be  
connected with cables of equal length.  
Operating +32° to +122°F (0° to +50°C) / 10% to  
90%, non-condensing  
Rack mount ................................... Yes, with optional 1U rack shelf, part #60-190-01  
Enclosure type .............................. Metal  
Enclosure dimensions ................. 1.75" H x 8.75" W x 9.4" D (1U high, 1/2 rack  
The level and equalization adjustments have no affect on the  
buffered loopout, which should not be run the long distances as  
the amplified outputs.
