Features

Four Inputs and One Output
Supports all HDTV modes 480i through 1080p, including 720p and 1080i. Each input consists of six analog channels (Pr/Pb/Y/Left/Right/CV) and one channel of Digital Audio. Analog audio channels are routed using the same high-bandwidth relay switches as the video channels, and can be used to route H & V components (with proper adapter cables) for an RGBHV switch, supports all RGBHV PC modes.

Passive Switching of Analog Signals
The HDS4.1 passively switches its analog signals using high quality relays designed specifically for switching low level signals such as those used in the audio and component video paths. Relays offer a switching quality like that of physically swapping cables, without the added noise and distortion that is inherent in active switches. This also allows the HDS4.1 to be used in reverse. The Output can be used as an input and switched to each of four outputs.

Break Before Make Switching Logic
Unlike our competitors, all of our relay based switches have always featured a 20 millisecond break before make switching sequence. The 20ms delay, when switching between inputs, guarantees that all relays have fully deactivated before the next input's relays activate, thereby preventing a momentary short between inputs.

Fully isolated analog grounds
The HDS4.1 features full isolation of its analog and digital grounds to eliminate digital noise from being superimposed on its analog signals, and to help eliminated ground loop problems.

5.1 Multi-channel Audio Switch
Since there are six available analog channels, the HDS4.1 can easily be used as a four to one 5.1 multi-channel audio switch. The fully passive design, and full isolation of the digital and analog grounds, makes the HDS4.1 ideal for switching analog audio signals between SACD and DVD-Audio players.

High Quality Gold Clad, Silver-Palladium Relays
All analog signals are switched using high quality relays with gold clad, silver-palladium (AgPd) contacts. The combination of gold clad on silver-palladium while expensive, holds the highest rating for long life, when switching low level signals such as those found in analog audio and video paths. Each analog channel is routed using a separate relay, thus reducing the possibility of cross talk between channels, when compared to the less expensive design of using multi-contact relays and routing multiple signals through a single relay.

Gold Plated Connections
Gold plated RCA connectors are used throughout the design to reduce the possibility of contact generated noise caused by corrosion.

Toslink and SPDIF Digital Audio
Both Toslink (Optical) and SPDIF (Coax) can be routed through the HDS4.1. Either input will be accepted and both Toslink and SPDIF are available as outputs simultaneously. All conversions between formats are done as needed.

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 from input two back to input one!

Full Featured Remote Control Interface
A full featured IR command set is available using any remote control, commands are: Power Toggle, Direct Channel Selection of each input, and for better integration with universal remotes with macro capabilities, the discrete commands Power On, and Power Off are also available.

Features Zektor's Exclusive IIR Learning
The HDS4.1 features Zektor's exclusive IIR (Intelligent Infra-Red) learning. Zektor's IIR learning allows the HDS4 to work with virtually any remote control! Control the HDS4.1 with an obsolete TV remote. The HDS4.1 also works great with any universal remote control.

Since Zektor's IIR™ allows you to use any remote, you don't need to order a remote if you plan on using your own remote to operate the HDS4.1.

Auto Dimming Display
The LED indicator lights can be set to Bright, Dim, Auto Dim, or Off. The Auto Dim mode will fade the LEDs from the Bright setting to the Dim setting about 4 seconds after a channel is selected.

Adjustable Front Panel LED intensities
The intensity levels of the front panel LEDs are fully adjustable, allowing the HDS4.1 to be used in a wide range of lighting conditions. The front panel can even be made to gently dim its front panels lights to 'off' when the front panel is not in use.

Rack Mountable Metal Enclosure (1RU)
Enclosed in a heavy gauged, steel chassis, and with fully adjustable front panel LED intensities, the HDS4.1 easily integrates into your existing home theater environment.

Optional International Power Supply
Available with an international power supply for 90-264VAC, 47-63Hz operation. The international supply comes with adapters for UK, EURO, AUS and USA use.
