REALTIME ANALYZER

QUICK START

If you are familiar with real time analyzers, feel free to jump right in. To avoid some of the lurking sharks read these

few tips as a reminder of what it is you already know:

FLAT IS NOT BEAUTIFUL. Equalizers have two basic purposes: correction and enhancement. The Rane analyzer

allows you to accurately correct system response to each location. A task very difficult to do by ear. Once this is quickly

done, then you adjust for further sound quality enhancement by ear; only rarely will a system be left in a “flat” condition.

USE MORE THAN ONE TEST MICROPHONE LOCATION. Speaker dispersion characteristics vary greatly, from

beamy highs to boomy bass traps. While performing the pink noise test, try at least two different test mic locations and

average the two if they differ.

USE ENOUGH PINK NOISE VOLUME TO OVERRIDE BACKGROUND NOISE. There’s no need to run

deafening pink noise levels to EQ a system. Just be sure that no green/red LED responds when pink noise is turned off (if

they do, background noise is causing erroneous readings and pink noise should be turned up higher).

USE ±3 dB DISPLAY SETTING FOR LOW FREQUENCY ADJUSTMENTS. The crest factor (peak response) of

true pink noise causes considerable LED flutter in the ±l dB mode, making it difficult to adjust quickly. We recommend

that the ±3 dB setting be used on frequencies below 500 Hz or so; use the ±l dB on the more sensitive mids and highs.

MONITORING PROGRAM WITH ANALYZER DISPLAY. When the front panel microphone is unplugged, the

analyzer display automatically monitors the RA 27 LINE INPUT signal. Use this feature to identify specific feedback

points by watching for red LEDs during the performance. You can then apply EQ exactly where it’s needed very quickly. If

all else fails, read the rest of the manual.
