Overview

3 Overview

The 88 Series is a group of 8x8 Vertical Interval Matrix Switchers

and a

Remote Control Panel for video/stereo audio/data signals that support the

simultaneous connection of one or more inputs to several outputs

. Vertical

Interval Switching

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 breaks

. 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 lines

(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

Your Matrix Switchers

Positioning the switcher correctly. Each switcher is housed in a professional

19-inch rack mountable enclosure, requiring one vertical rack space per

product

. 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 products

in the 88 Series range that can function

separately

or switch together in the same manner in the In System mode

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

system

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

Table 1: VS-88A 8x8 Balanced Audio Matrix Switcher Features

# Feature Function

1 POWER Switch Illuminated switch supplying power to the unit

2 ALL Button Pressing ALL before pressing an INP button, connects that input to all outputs

3 OFF Button Pressing OFF after pressing an OUT button disconnects that output from the

inputs. To turn off the connections, press the ALL button and then the OFF

button

4 IN Select the output to which the input is switched (from 1 to 8)

SELECT

Buttons OUT Select the input to switch to the output (from 1 to 8)

5 STO Button Pressing STO (Store) followed by an output button stores the current setting

(refer to section 8.2.1)

6 RCL Button Pressing the RCL (Recall) button and the corresponding OUT key recalls a

setup. Press the RCL button again to implement the new status (refer to section

8.2.2)

7 IN SYSTEM Button Pressing IN SYSTEM twice

, switches between the Standalone mode (in which

the switcher implements any action independently from the others) and the In

System mode (in which all switchers implement the same action simultaneously)

8 TAKE Button

(TAKE = CONFIRM)

Pressing TAKE toggles the mode between the CONFIRM mode

and the AT

ONCE mode (user confirmation per action is unnecessary)

9 OUTPUT labels Identifies a connection between the output and the input shown below it

INPUT Status Display Displays the selected input switched to the output (marked above each input)

10 INPUT Terminal Block

Connectors

Connect to balanced stereo audio sources (from 1 to 8)

11 OUTPUT Terminal

Block Connectors

Connect to balanced stereo audio acceptors (from 1 to 8)

12 MACHINE # Dipswitches setup (refer to section 6.1)

13 RS-485 Connector RS-485 detachable terminal block port. Pins # 1 to # 3 are for RS 485 and pin #

4 is for vertical sync distribution

as Figure 7 illustrates

14 Power Connector with

Fuse

AC connector enabling power supply to the unit

15 RS-232 OUT 9-pin

D-sub Connector

Connects to the RS-232 IN 9-pin D-sub port of the next unit in the daisy-chain

connection

16 RS-232 IN 9-pin

D-sub Connector

Connects to PC or Remote Controller

1 For example, press ALL and then Input button # 2 to connect input # 2 to all the outputs

2 For example, press STO and then the Output button # 3 to store in Setup # 3

3 After pressing IN SYSTEM once, it blinks

4 When in Confirm mode, the TAKE button illuminates

5 The 88 Series RS-485 connector has 4 pins, and the remote controller RS-485 connector has just 3 pins

6 If the unit is the final unit in the daisy-chain connection, no termination is required

7 If the unit is not the first unit in the line, connects to the RS-232 OUT 9-PIN D SUB port of the previous unit in the line

Switches during the vertical interval

Accepts analog video as the external source for its vertical interval trigger

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

system
