RGB4X-R Performance Review:

 

With all the money you spend on your Home Theater system, you want to be sure that any component you install does not degrade the final picture. The system is only as good as its weakest link!

 

A Component Video Switcher is one of these critical links. So how does the RGB4X-R perform? Is it going to degrade the Component Video Signal? In pure performance, the RGB4X-R is the highest performing Component Video Switcher under $1000. We use only the best Switching IC's( Analog Devices AD8184 ) and High current video output drivers available. Others use relays and switches, which honestly, are perfectly fine for short lengths, but if you need to drive more the 10 feet of cable, you need a active circuit to drive that cable.

 

Below are the actual Oscilloscope pictures of the RGB4X-R compared to the Shinybow™ YUV and the "OTHER" (see notes below) The results speak for themselves. As you will see, Video Bandwidth is often overstated!

 

0 to 120MHz Sweep

What to watch for: Reduced level and 'bumps' in the waveform.

 

Top trace: INPUT

Middle trace: 30, 60, 90, 120MHz frequency markers

Bottom trace: OUTPUT

 

The SHINYBOW starts dropping at around 5MHz and has some bad phase modulation.

The "OTHER" is -3dB at 60MHz and continues to drop. The input is not properly terminated.

NTSC Color Bars

What to watch for: Noise in the signal

White Field

What to watch for: Field Integration (ramping). Caused by poor Low Frequency Response.

Can cause flashes in picture during dark to bright scene changes.

The Inday and "OTHER" have proper low end frequency response. The SHINYBOW does not

50MHz Pulse Response

What to watch for: Reduced Level and rounded edges. Causes detail loss in picture

Top trace: Input. Bottom Trace: Output

You want the Output should look just like the Input. The Inday RGB4X-R is closest to achieving this.

The SHINYBOW is down > 12dB. The OTHER is down about 4dB and has lost all its edges.

25MHz Pulse Response

What to watch for: Reduced Level and rounded edges. Causes detail loss in picture

Top trace: Input

Bottom Trace: Output.

Even at 25MHz the SHINYBOW is down greater than 6dB.

10MHz Pulse Response

What to watch for: Reduced Level and rounded edges. Causes detail loss in picture

The competition states is bandwidth is > 100 MHz.

Top trace: Input

Bottom Trace: Output

The SHINYBOW at 10MHz is down about 3dB. This switch will have trouble passing even Progressive Scan DVD.
