KRAMER:  SIMPLE CREATIVE TECHNOLOGY

 

Overview 

 

In particular, the 

VM-25

:

 

Includes a looping connector for connecting to a local monitor, other 

acceptor, or for forming larger systems

1

 

Has a video bandwidth of more than 430MHZ, ensuring transparent 

performance with typical video sources 
Has front panel video trimmer controls

2

 for output level (LEVEL) and 

cable equalization (EQ.) 

Achieving the best performance means: 

Connecting only good quality connection cables, thus avoiding 

interference, deterioration in signal quality due to poor matching, and 

elevated noise levels (often associated with low quality cables) 
Avoiding interference from neighboring electrical appliances and 

positioning your 

VM-25

 away from moisture, excessive sunlight and dust 

Figure 1 and Table 1 define the 

VM-25

 

1:25

 

Video Distribution Amplifier

 

                                                       

 

1 For example, you can connect 3 VM-25 units to make a 1:75 video distribution amplifier. See section 4.2 for details 
2 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately 
trimmed for output level and cable equalization (EQ.) thus achieving different compensations for different cable lengths
