control offers a wide range of control covering from

0 dB to 120 dB.

Press the GAIN switch and use the

Data Wheel to adjust the level either up or down .

DETECT

The D1500 RTA can respond using both PEAK and

RMS detection. The detection algorithm determines

the speed, or ballistics at which the RTA reacts to

the incoming signal. When set to PEAK the RTA will

respond quickly to the absolute highest level. When

RMS is selected, the RTA uses

root mean square

av-

eraging which will cause the meters to react slower.

To set the detection mode, press the DETECT switch

and use the Data Wheel to select either PEAK or

RMS.

INTEG – INTEGRATION

The speed at which the D1500 LED meters respond

can be adjusted using the INTEGRATION parameter.

The INTEGRATION time can be set in a range from

15 milliseconds, all the way to 20 seconds.

WEIGHT

The D1500 lets you apply audio industry standard

equalization curve filters to the input of the RTA.

You can select A, B, C or D filter curves or NONE if

you choose. To select the input filter curve, press the

WEIGHT switch and use the DATA Wheel to select

the desired filter curve.

Operating the D1500

Adjusting the RTA parameters

Before you get started using the RTA function, press and

hold the RTA switch for about two seconds and take no-

tice of the parameters that can be adjusted while using

the RTA. You’ll notice that the SOURCE, GAIN, DETECT,

INTEG, WEIGHT, REF, RES, HOLD and FREQ are all illumi-

nated indicating that the parameters can be edited.

SOURCE

The D1500 can analyze an audio signal from its Left

and Right inputs or from the Mic input when con-

nected to a measurement microphone. The SOURCE

switch allows you to select one of the three input

configurations; LEFT, RIGHT, or LEFT + RIGHT.

If you want to measure a mono signal from either the

LEFT or RIGHT inputs select LEFT or RIGHT respec-

tively.

If you want to measure the response curve from a

stereo source select LEFT + RIGHT.

For measuring room response using a test micro-

phone select MIC from the Global menu as described

in section

"Selecting the input"

on the previous page.

Note: The D1500 can also analyze a digital audio sig-

nal when fitted with the optional DIO1 digital input

and output interface card.

GAIN

The GAIN control is used to set the reference point of

the RTA display. You can slide the scale of the RTA dis-

play using the GAIN. Once you confirm that you have

set the correct operating level for your line or mic

input (using the GLOBAL set up and the main input

meter), you can adjust the GAIN so the RTA response

is in a good range with most of the readings averag-

ing halfway up the display. The D1500’s GAIN
