Overview

3 Overview
The 88 Series is a group of 8x8 Vertical Interval Matrix Switchers1 and a
Remote Control Panel for video/stereo audio/data signals that support the
simultaneous connection of one or more inputs to several outputs2. Vertical
Interval Switching3 ensures an undisturbed picture transition. The major
innovation with the 88 Series is the ability to switch different kinds of signals
simultaneously. Section 3.1 outlines the 88 Series and section 3.2 includes
recommendations for achieving high quality performance.
3.1 The 88 Series
The 88 Series includes the following items:
VS-88A (stereo audio matrix switcher for analog balanced audio)
VS-88V (video matrix switcher for analog composite video)
SD-7588A (audio matrix switcher for digital audio)
SD-7588V (video matrix switcher for digital video)
RC-8000 (remote controller for use with the switchers)
3.2 High Quality Performance Recommendations
Achieving high quality 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)
Using good quality sockets and connectors for the sources and acceptors to
avoid signal path breaks4. Aim for Zero Ohm connection resistance and ensure
that sockets and connectors match the required impedance (75 ohms in video)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality. Install unbalanced audio and video lines5
(even though the cables are shielded) away from mains carrying cables, electric
motors, and transmitters
1 Switching is implemented during the vertical interval period according to the SMPTE RP-168 standard, when using
synchronized SDI sources
2 However, you cannot connect two or more inputs to a single output
3 Frequently used when recording or transmitting a video program involving several video sources
4 Poor quality connectors tend to rust, which may cause breaks
5 Balanced audio lines are less prone to interference

Positioning the switcher correctly. Each switcher is housed in a professional
19-inch rack mountable enclosure, requiring one vertical rack space per
product1. The standard 19-inch (IU) EIA rack assembly requires no specific
spacing above or below the unit for ventilation
4 Your Matrix Switchers
This section describes the products2 in the 88 Series range that can function
separately3 or switch together in the same manner in the In System mode4.
4.1 Your VS-88A 8x8 Balanced Audio Matrix Switcher
The VS-88A is a high performance 8x8 stereo audio matrix switcher for
balanced audio stereo signals using detachable terminal block connectors. In
addition, the VS-88A:
Is a true matrix switcher, enabling the user to simultaneously route any input to
any or all outputs
Delivers excellent audio performance ensuring that it remains transparent in
almost any audio application
Is controllable via the front panel buttons as well as the built-in RS-232 and
RS-485 interfaces
Includes 15 preset memory locations for quickly and easily accessing the most
frequently used configurations
May be used with the RC-8000, an optional remote controller (see section 0)
Functions as a standalone unit as well as part of a Kramer multi-signal switcher
system5
Figure 1 and Table 1 define the VS-88A:
1 To install a switcher in a rack, see section 5
2 Switchers in the 88 Series share identical front panel controls. Video switchers with the suffix V, have rear panel BNC
connectors. Audio switchers with the suffix A, have rear panel detachable terminal block connectors
3 Standalone
4 Section 7 describes the different modes
5 Which includes digital and analog video, digital and analog audio and RS-422 control switchers. When integrated in a
system, it switches together with the video during the vertical interval, thus supporting true IN SYSTEM mode
