Extron electronic manual Audio, General, DVS 605 • Introduction

Audio

•Audio switching — The DVS 605 A and DVS 605 AD feature audio switching for five analog stereo balanced or unbalanced inputs.

•Output volume control — DVS 605 audio models provide master volume control. Fixed and variable line level outputs are available, and each output can be balanced or unbalanced. Stereo input signals can be output as dual mono. The DVS 605 audio models also include a S/PDIF digital audio output.

•Audio input gain and attenuation — Gain or attenuation can be adjusted for each analog audio input to eliminate noticeable differences when switching between sources.

•Audio breakaway — Provides the capability to break an analog audio signal away from its corresponding video signal and route to the audio outputs, allowing the analog audio channels to be operated as a separate switcher.

•Audio switching transitions — A transition technique can be applied during switches that lowers the audio of the switched-out source while simultaneously bringing up the audio of the activated source. The duration of the audio crossfade matches the duration of the video switching transition.

•Integrated audio delay — The DVS automatically delays all analog and digital audio inputs to compensate for internal video processing delay. Occasionally additional audio delay is required to account for other signal processors, scalers, or display devices in a system. For these situations, the DVS 605 offers an additional 0-255 ms static global audio delay that can be set via SIS command or internal web pages to eliminate audio “lip sync” issues.

•HDMI audio embedding and de-embedding — For DVS 605 models with audio, analog input audio signals can be embedded onto the HDMI output signal.

The DVS 605 can also extract PCM embedded HDMI audio signals. Encoded bitstream audio for Dolby® Digital or DTS® Digital Surround a can be passed to the HDMI and S/PDIF outputs.

General

•HDCP compliance — features include data rates up to 6.75 Gbps, Deep Color, and HD lossless audio formats.

•HDCP authentication and signal presence confirmation — The DVS 605 provides real-time verification via RS-232 or Ethernet of the HDCP status for each digital video input and output. This allows for signal and HDCP verification through USB, RS-232, or Ethernet, providing feedback to a system operator or helpdesk support staff.

•HDCP visual confirmation — This provides a green signal when encrypted content is sent to a non-compliant display, providing immediate visual confirmation that protected content cannot be viewed on the display.

•Key Minder — This feature continuously verifies HDCP compliance for quick, reliable switching. It authenticates and maintains continuous HDCP encryption between input and output devices to ensure quick and reliable switching while enabling simultaneous distribution of a single source signal to one or more displays.

•Advanced scaling engine — The DVS 605 features a high performance 30-bit scaling engine with the ability to scale high resolution computer-video and HDTV as well as standard definition video up or down in resolution.

•EDID Minder — This feature automatically manages EDID communication between connected devices, ensuring all sources power up properly and reliably output content for display.
