The HDS4x2 is a 4 input, 2 zone (outputs), non-blocking, active matrix component video (Y/Pb/Pr) switch.

The HDS4x2 features a 400MHz bandwidth giving it the ability to pass all HDTV 1080p60 signals, including 3rd harmonics, effortlessly.

The HDS4x2 includes stereo analog audio switching as well as both optical and coax formats of digital audio switching. Conversion between coax and optical digital audio are done automatically.

Full discrete IR codes are available for power and inputs, switch any input to any output with a single IR code. A rear panel hardware IR jack and RS-232 port are also included.

Features

True Ultrawide Bandwidth: 400MHz

We've gone out of our way to bring the quality and specifications you'd find on a professional video switch, to the home theater market. And we started with bandwidth. To correctly display sharp images at 1080p60, a switch or distribution amplifier must be able to pass at least the third harmonic of the video signal, and the third harmonics of a 1080p60 can be as high as 280MHz. With a -3db bandwidth of 400MHz, the HDS4x2 effortlessly passes 1080p60 and all it's third harmonics.

Four Inputs and Two Zones (Outputs)

Each zone consist of three channels. A component video channel, an analog audio channel, and a digital audio channel.

Easy to use Front Panel Control of Switching

Front panel buttons are available to directly select each input. You are not forced to sequence through all inputs when switching a zone from input two back to input one.You are also not forced into a series of three or four key presses each time you want to change an input. Front panel operation is as simple as selecting a zone (or zones), and then switching between inputs as simply as you would with a single zone switch. The dual 7-segment LEDs always display how each input is mapped to each zone, without the need of any key presses to request the information.

Front Panel Breakaway

Full audio and video breakaway is available on the front panel. Switch just the audio channels or just the video channels of any zone. Watch the game while listening to CD's!

A Real Analog Audio Section

Analog audio is not an after thought on the HDS4x2, nor is it just another channel of an internal video switch. The HDS4x2's analog audio section has been designed using very low noise, low offset amplifiers, switches, and buffers designed specifically for analog audio. To prevent video and digital noise from leaking into the audio section, the HDS4x2 audio section has its own power supply regulation, which is not shared with the video or digital sections.

True Digital Audio Switching

Be weary of a manufacturer that states their "digital audio coax" channel can double as a composite video switch. This is a good indication they are using a composite video switch to route digital audio, and that they are not S/PDIF compliant! To be S/PDIF compliant, a switch must be able to receive a full range of input voltages, and yet output a nominal 500mv signal into 75 ohms, regardless of the input voltages. A composite video switch will simply pass out of spec levels straight through to the output. It's impossible for a S/PDIF compliant switch to pass composite video.

The HDS4x2 can accept any range of inputs from 200mV to 7V and and regardless of input values, will drive the coax outputs with the proper 500mV required by the S/PDIF specifications. We use high current drivers with the power needed to drive extended length cables. True S/PDIF audio switching also allows us to clean up noisy signals and automatically convert between coax and optical on both the inputs and outputs, something that cannot be done using a "composite video" channel to route digital audio.

D.C. Coupled Video Inputs and Outputs

D.C. coupled inputs and outputs are usually found only in professional, or passive (relay based) switches. In the HDS4x2, D.C. coupling is used throughout the video section. A completly black screen is passed with no field tilt distortions, as well as a completly white screen. By using a D.C. coupled design, we've also eliminated the "roll" that sometimes occurs on A.C. coupled switches when the screen changes quickly from very dark to very bright (or vice versa).

D.C. Coupled Audio Inputs and Outputs

D.C. coupling is used throughout the audio section, there are no blocking capacitors to cause audio distortion. The HDS4x2 audio frequency response extends from 0Hz (DC) to (TBD), well beyond human hearing. There is no bass roll-off in the HDS4x2, which means no loss in those chair rattling subharmonics that can reach down into the single digit frequencies (<10Hz).

Adjustable Mute Switch Delays

The HDS4x2 supports video / audio blanking during switching, sometimes called "Fade to Black". Each zone can be individually set to blank its video or mute its audio for an adjustable amount of time during switching. This can help eliminate the "rolling" that sometimes occurs when quickly switching between two un-synchronized video sources. The adjustable audio mute delays can also help eliminate the "thumps" that sometimes occur when digital audio is switched quickly.

Complete control is given over all switching delays on the HDS4x2, not only is each zone individually adjustable, but each channel of each zone is individually adjustable. For instance you can have Zone1's video blank for 200ms, while the digital audio only mutes for 10ms, and yet have analog audio switch with no delays. Zone2's timings can be set differently.

All timings can be adjusted to match the needs of any piece of equipment you have connected to the HDS4x2.

Five Separate Power Supply Regulators

To help keep digital noise from finding its way into the analog sections, the HDS4x2 incorporates five separate power regulators that supply power to the Video, Audio and Digital sections. By using separate regulators for the different subsections, we've reduced the possibility of video banding caused by digital audio signals leaking into the video section. Or the possibility of analog audio buzzing because video sync pulses have leaked into the analog audio section. These are problems that can occur when power supplies are shared.
