1:5 s-Video/Composite/Audio Distributor 

 

Several words on Distribution Amplifiers:   

 
 

Distribution amplifiers distribute one signal to several users. They 

vary in the number of inputs, looping capability, number of outputs, 
operating format, bandwidth and input/output coupling. Distribution 
amplifiers are used to distribute one video and/or audio source to several 
video/audio acceptors for simultaneous recording or monitoring one source. 
 

A good quality distribution amplifier amplifies the incoming signal 

(video and audio), pre-compensates the signal for potential losses (resulting 
from the use of long cables, for example) and generates several identical 
buffered and amplified outputs. 
 

Often, a signal processor is inserted between the source and the 

distribution amplifier for correction and fine-tuning of the source signal 
before multiplication, thus all copies are corrected in the same way.  
 

There are many factors effecting signal quality when transmitted from 

a source, to an acceptor: 

 

Source and acceptor signal handling capability - as different brands offer 

different qualities and the result is limited by the lowest quality part 
performance. Using a low quality source will always result in low quality 
duplicates. 

 

The connection cables should be of the best quality you can afford. Low 

quality cables are susceptible to interference, deteriorate signal quality due 
to poor matching and cause elevated noise levels.  

 

Sockets and connectors of the sources and acceptors - so often ignored, 

should be of best quality, as "Zero Ohm" connection resistance should be 
assured. Sockets and connectors should match the required impedance (75 
ohms in video). Cheap connectors tend to rust, causing breaks in the signal 
path. 

 

Amplifying circuitry quality is extremely important and is needed for 

high linearity, low distortion and low noise operation. 

 

The distance between source and acceptors plays a major role in the 

result. If long distances (over 15 meters) exist between sources and 
acceptors - special means should be taken in order to avoid cable loss, such 
as using higher quality cables or if necessary - line amplifiers. 

 

Interference from neighboring appliances may have an adverse effect on 

signal quality. Balanced audio lines are less prone to interference, but 
unbalanced audio and video lines, even though the cables are shielded, 
should be installed far away from mains carrying cables, electric motors, 
transmitters etc. 

 

The KRAMER VM-5YC 

The KRAMER 

VM-5YC

 is an extended bandwidth, state-of-the art 

YC/Video/Audio Stereo Distribution Amplifier 

designed for studio and other 

demanding applications. The 

VM-5YC

 splits a single input source into five 

identical outputs with no discernible signal degradation. Hundreds of copies 
of videotapes can be made at the same time using several 

VM-5YC

 units 

chained through the looping inputs.  The user may select video AC or DC 
coupling for full flexibility. 

The 

VM-5YC

 has an additional unique feature - by a flip of a switch, 

it allows converting a YC source to 5 Composite Video outputs.

  

 

Operation: 

 

Connect composite or Y/C video and audio stereo sources to the 
appropriate inputs of the 

VM-5YC

 

Select with the rear-mounted switch whether AC or DC coupling is 
needed. 

 

If an Y/C input is connected, select with the MODE rear switch whether 
you want to distribute plain Y/C signals (switch is on the "YC" side) or 
convert the Y/C input to five Composite Video outputs (switch is on the 
"YC to CV" side.) 

 

Connect up to five Video/s-Video/Audio acceptors to the output sockets. 

 

If looping is needed, connect a second unit to the "LOOP" sockets, toggle 
the termination switch on the first unit into the "Hi-Z" position and the 
next unit into "75 Ohms" position.
