RTA - Band-Pass

The RTA (Real Time Analyzer) - Band-Pass component allows you to measure the magnitude of a signal over the audio frequency range. The RTA - Band-Pass is typically used for tuning your system. For example, you can place microphones around your venue, feed them into the RTA - Band-Pass, and adjust the EQ for the individual areas to get the best/same tuning for each area.

Control

Function

Default / Range

Response Panel

Graphical display of the RTA - Band-Pass response.

X Axis = 20Hz to 20kHz

Y Axis = -80 dB to 20dB

RMS Response Time Constant

(ms / sec)

Sets the RMS Level Detector time constant for both attack and decay.

This controls how quickly the RTA - Band-Pass A respond to changes in the input levels.

Default = 100 ms

Range = 100 ms to 30 sec

Max Hold Time

(seconds)

Sets how long the maximum magnitude displays are held before refreshing.

Default = 1

Range = 0.1 to 10

Infinite Hold

(button)

Holds the display, until the button is disengaged.

During the period the Infinite Hold button is on, the RTA - Band-Pass updates the display with any magnitudes that are higher than the initial response, but does not change if the magnitude is lower.

Off / On

Clear Response

Clears the Response Panel display.

Choices

Bandwidth

Selects the bandwidth for the band-pass filters in the RTA - Band-Pass.

One octave provides 10 filters for the audio spectrum giving a wide bandwidth for each filter and a smoother response. A bandwidth of 1/24 octave provides 124 filters giving a narrow bandwidth for each filter, and a more granular response - more distinct highs and lows.
