3  Overview 

The Kramer 

VS-88HC

 is a matrix switcher designed for high quality home 

entertainment. It is a true 8x8 matrix switcher for HDTV compatible, 

component video (Y, Pb/Cb, Pr/Cr), digital audio (S/PDIF) and analog 

unbalanced stereo audio signals, letting you simultaneously route any of the 

eight inputs to any or all of the eight outputs. The component video, S/PDIF 

and analog audio signals are on RCA connectors. The S/PDIF 

INPUT/OUTPUT 2 is also available on optical (TOSlink) input/output 

connectors. 
The 

VS-88HC

 features: 

 

A resolution of up to 1080p, fully loaded 

 

An audio channel sampling rate of up to 192kHz, including 

multi-channel audio (suitable for multi-channel applications, 

like AC3)  

 

A built-in digital audio delay line on OUTPUT 2, which corrects 

lip sync errors, so that the audio delay will match the video delay 

 

DC coupled video inputs and outputs 

 

Audio-follow-video and breakaway options, as well as input 

and output analog audio level control 

 

Storing and recalling of 16 setups 

 

A TAKE button for precise switch control 

 

A LOCK button to prevent tampering with the front panel 

 

A 7-segment display showing the status 

Control the 

VS-88HC

 using the front panel buttons, or remotely via: 

 

RS-232 and RS-485 serial commands transmitted by a touch 

screen system, PC, or other serial controller 

 

The Kramer infra-red remote control transmitter 

 

The ETHERNET 

 

An external remote IR Receiver (optional)  

To achieve the best performance: 

 

Connect 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) 

 

Avoid interference from neighboring electrical appliances that 

may adversely influence signal quality and position your Kramer 

VS-88HC

 away from moisture, excessive sunlight and dust
