Setup/Configuration Screen

Rotate the data wheel to scroll across the screen and push the wheel to select and confirm.

A B C & D INPUTS:

Input sensitivity switches between –10 dBV or +4 dBV inputs. The +4 dB position should be considered the “normal” position and should be used with professional systems. The -10 dB position allows the unit to be driven with “hi-fi” level equipment or directly from a CD player.

Mute toggle on/off.

Analog/digital operation is selectable on input A.

Level controls digital processing headroom and is adjustable from 0 dB through –100 dB. This adjustment is best left as high as possible but may be adjusted as necessary.

Trim is variable from –6 dB to +6 dB and is used to match analog input sensitivity as necessary. Exit this screen by selecting “Done” and pressing the data wheel or pressing the “setup” button.

ST/M:

Toggles between Stereo and Mono. Selecting Stereo associates the A/B channel inputs. It does not affect the output channels. When engaged in “stereo” adjusting a parameter on channel

A will make a corresponding adjustment on Ch B. This may be most useful when adjusting PEQs, Delay or Dynamic settings. Preliminary adjustments can be made to both channels in this manner and then the switch can be toggled to mono allowing further independent adjustment of single inputs. The switch may be toggled again to link up the dynamic sections for stereo tracking of the comp/limiters.

MIC:

Allows engaging the +48 V phantom power as well as adjusting the Mic gain range from 23 dB to 67 dB of gain. Select “done” or press “setup” to escape to the main screen.

GEN:

This screen selects the parameters for the signal generator. Pink, White or Sine may be selected. When Sine is selected the frequency of the sine wave may be adjusted for 20 Hz to 20 kHz. The output level may be adjusted by highlighting the fader graphic and adjusting the Level control. An In/Out button is provided

to turn on and off the generator. The screen may be exited by selecting “done” or pressing the “setup button. The Generator must be assigned to an output of your choice with the Matrix. A single Band pass filter can also be assigned to that output and the skirts may be adjusted to provide limited bandwidth noise for testing purposes.

Matrix:

The matrix provides the method to assign inputs to outputs. In the default configuration NO SIGNAL IS PASSED through the unit until some selection in the matrix is made. This prevents potentially destructive signals from reaching the wrong outputs. The inputs are represented by the rows and the outputs by the columns. Most users will commonly assign crossovers in the setup screen so that only a single input assignment will be necessary. In addition to the line inputs the Mic and GEN inputs are assigned in this screen. To continue from the matrix you must

exit from the upper left or the lower right squares.

VSX 48 specifications

The Peavey VSX 48 is a sophisticated digital loudspeaker management system designed for professional audio applications, blending advanced features with user-friendly functionality. With the ability to manage and optimize sound across various environments, the VSX 48 stands out as a powerful tool for sound engineers and audio professionals.

One of the main features of the VSX 48 is its high-bandwidth digital signal processing capabilities. Operating at a 48 kHz sample rate, it ensures pristine audio quality and minimal latency. The system boasts 4 input channels and 8 output channels, allowing for extensive routing and configuration possibilities. Each channel is equipped with a 24-bit AD/DA converter, ensuring that the audio signal remains transparent and true to the original source.

The VSX 48 is built around a comprehensive set of processing tools, including parametric equalizers, crossover filters, and delay options. The 8-band parametric equalizers for each output channel allow users to fine-tune frequencies with precision, helping to eliminate feedback and enhance sound quality. The crossover filters support various configurations, enabling the separation of audio signals into different frequency bands for optimized performance of amplifiers and loudspeakers.

Another distinctive technology is the integrated feedback suppression system. This feature actively identifies and reduces feedback in real-time, allowing for a cleaner and more professional sound. The delay functionality is particularly useful for time-alignment of multiple speaker arrays, ensuring that sound reaches the audience in a coherent and unified manner.

The device also features an intuitive user interface, accessible via both its front-panel controls and a computer-based software application. This allows users to monitor performance and make adjustments easily, whether on-site or remotely. The MIDI compatibility of the VSX 48 also enables external control and integration into complex audio setups, increasing its versatility.

Durability is a key characteristic of the VSX 48, designed to withstand the rigors of touring and live sound environments. With its sturdy chassis and reliable components, it is built for longevity, making it an ideal investment for any audio professional.

In summary, the Peavey VSX 48 is a robust and flexible loudspeaker management system that combines advanced digital processing technologies with user-friendly operation. Its comprehensive features make it a valuable asset for achieving optimal sound quality in various audio environments. Whether for live performances, installations, or sound reinforcement, the VSX 48 stands out as a reliable choice for audio excellence.
