Product Overview

The KD-ADA4 HD View4 is a very versatile and novel Distribution Amplifier

(DA) that will suit your needs for crystal-clear distribution of HDTV and SDTV

Component Video (YPrPb) or Composite Video (CV) sources to Component

Video "HDTV-ready" monitors, or Composite Video monitors. Signal process-

ing circuitry permits excessive distribution cable runs of up to 1000 feet, with

 

HD

simple front-panel adjustments. And you can drive four component or compos-

ite monitors simultaneously. Each unit handles Left and Right stereo audio, or

digital PCM audio.

HD View4 provides so much flexibility, yet will not degrade the image quality

 

of your input signals. Each unit can be cascaded to other KD-ADA4, KD-DA6,

 

or KD-CDA12 DA’s by Key Digital Systems, to drive as many outputs as

2

desired from one source. HD View4 has an added feature (via internal DIP-

switch control) whereby you can distribute only Composite Video (CV) or digi-

 

tal PCM audio inputs to as many as 24 destinations.

 

Why do you need a Distribution Amplifier?

For installations where you need to distribute your HD and SD video and analog or dig- ital audio to more than one destination, you need a high-quality Distribution Amplifier (DA). Perhaps you have a configuration where you need to distribute an HDTV Set Top Box output to several different display monitors. You’ll want to feel confident that the DA introduces little or no degradation to your signals.

Our DA’s produce crystal-clear images which do not harm your input signals, can drive long cables (typically up to 300 feet, and our ADA4 which can drive up to 1000 feet), and can be cascaded to accommodate future expansion requirements. Let us help you choose exactly the right DA for your specific installation application.

This allows users to connect multiple audio zones or devices simultaneously, providing enhanced audio capabilities across a wide area. Each output can be independently controlled, giving users optimal control over their audio environment.

The KD-ADA4 utilizes state-of-the-art technologies, including digital signal processing (DSP), to provide dynamic range control, equalization, and other audio enhancements. The inclusion of DSP ensures that the audio remains clean and professional, regardless of the source material or environment. This is particularly beneficial in settings where audio clarity is paramount, such as in conference rooms or live event venues.

Another core characteristic of the KD-ADA4 is its compatibility with a variety of audio sources. It supports both analog and digital inputs, including balanced and unbalanced connections. This flexibility makes it easy to integrate the KD-ADA4 into existing audio systems, allowing users to leverage their current equipment while updating their audio distribution capabilities.

Furthermore, the KD-ADA4 is designed with user simplicity in mind. It features intuitive front panel controls and LED indicators that facilitate easy operation and monitoring of the system's status. For more advanced configurations, users can utilize Key Digital's proprietary software, which enables complex setups to be managed via a computer interface.

Robust build quality is another important aspect of the KD-ADA4. Designed to withstand the rigors of commercial use, it features durable hardware and an efficient cooling system to ensure reliable performance during extended operation. This makes it a dependable choice for projects where downtime must be minimized.

In summary, the Key Digital KD-ADA4 is a versatile audio distribution amplifier that combines advanced technology, comprehensive connectivity options, and user-friendly features. With its robust performance and flexibility, it is an essential tool for any professional audio installation requiring reliable audio distribution across multiple zones or devices.
