Alesis prolineardsp User Manual

 

The ProLinear DSP has an extremely useful feature called 

Input Level mode that can help you optimize the speaker’s 

performance. This mode allows you to measure the level of  

the incoming signal, which in turn makes it possible to adjust 

the rear panel Input Level control to its ideal position.  

 

In addition to allowing you to achieve maximum signal 

integrity for an individual speaker, Input Level mode can also 

be used: 

1. 

To be certain that all ProLinear DSP speakers in the 
system are at the same level, and

 

2. 

To be certain all speakers are operating at an optimal 
signal-to-noise ratio (SNR).

 

 

To optimize your setup, you need to send a constant, steady 

signal to the ProLinear DSP speaker. Most audio engineers 

would send the unit pink noise, white noise or a sine wave. We 

recommend that you purchase a reference CD containing 

these and other signals commonly used for level calibration. 

It’s very difficult to calibrate any professional audio device 

using regular music or program material.  

 

To use Input Level mode: 

Hold for three 
seconds 

 

•  Starting from within Program mode, press and hold 

the Page button for three seconds. The following 

display is an example of  what may be shown: 

 

 

 

 

 

 

 

 

•  Once this display is showing, reach around to the 

back of  the ProLinear DSP and set the Input 

Level control to its minimum position.  

 

•  Select a test tone that has a level very close to 0dB 

on the CD player and send it to the speaker.  

 

•  Slowly increase the Input Level control until the 

display reads -10dB.  

 

To exit Input Level mode, hit the Page button again.
