Overview

3 Overview

The VS-3232A is a high-performance 32x32 matrix switcher (router) for

analog balanced stereo audio signals. The unit can route any or all inputs to

any or all outputs simultaneously.

The VS-3232A features:

Clean switching (noise free)

Level control for each input and output

An S/N ratio of over 100dB at +20dBu/1kHz and a linearity better than

0.1dB from -25dBu to +20dBu

THD and noise below 0.03%

A flat frequency response from 20Hz to 20kHz (±0.1dB)

The ability to operate as a standalone audio router or as a companion

router to the VP-3232V(xl)

The ability when connected to the VP-3232V(xl), to operate in audio-follow-

video or breakaway mode

Flexible control options: front panel, remote control via RS-232

(K-Router™ Windows®-based software is included), RS-485, Ethernet

and IR remote (included)

A TAKE button for executing multiple switches all at once

60 memory locations to store the machine's full status such as presets to be

recalled and executed when needed. One "Default" setup can be executed

immediately by pressing the default button

Front panel lockout

Two optional communication protocols, the Kramer 2000 and Sierra

ASCII protocols (partial)

A worldwide power supply, 100-240V AC on a standard 19” rack mount

size, with 2U Rack "ears" included

To achieve the best performance:

Use only good quality connection cables to avoid 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 VS-3232A away from

moisture, excessive sunlight and dust

The keypad selector buttons (illustrated in Figure 2 and Table 2) are used to

select the outputs and the inputs when routing

. Use the keypad button to

shift the display content to the left, and the keypad button to shift the

display content to the right (as the LCD display is only large enough to show

13 cross-points out of a total of 32). Most keypad buttons have more than one

function, as defined in Table 2.
