Overview

3 Overview

The high-performanceVP-1081:8 XGA / Balanced Stereo Audio DA is an

8-channel distribution amplifier for VGA/XGA and stereo audio (balanced or unbalanced) that uses 15-pin HD connectors for the VGA-type signals, and detachable terminal block connectors for the audio.

In particular, the VP-108:

￿Is unique in that each of the eight XGA outputs, and each of the eight stereo audio outputs, may be individually enabled or disabled1, replacing a switcher which would typically be used in such setups

￿Is controllable (switching of the outputs) via RS-232 or RS-485 serial commands transmitted by a touch screen system, PC, or other serial controller, as well as via external dry contact switches

￿Stores the output configuration in non-volatile memory so that the machine will restore its power-down status when power is returned

￿Uses solid-state electronic switching, and low-noise amplifying circuitry throughout the unit, and the sync pulses are detected and reconstructed before amplifying and buffering to the outputs

￿Has a high video bandwidth, ensuring that each unit remains transparent even at the highest resolution VGA modes such as XGA

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 VP-108unit in a location free from moisture, excessive sunlight and dust
