1. Sine – Select here to turn on a pure sine wave test tone.

2. Pink Noise – Select here to turn on a pink noise test signal.

3. Square – Select here to turn on a square wave test tone.

Caution: Take care with the use of test tones in case the ampliers

in your system take oence and overheat, or this causes damage

to your hearing. Ampliers (and ears) are much more used to the

normal ups and downs of musical program material, than the

constant sine wave test tones, especially at the lower frequencies.

4. Frequency – The sine wave or square wave test tone frequency

can be changed by dragging this control left or right.

If you press and hold the round encoder knob on the actual

DM-RTA device, the frequency will increase in Octave steps.

5. Frequency Value – Alternatively, you can adjust the sine wave or

square wave frequency by entering a numeric value here.

6. Output Level – You can adjust the output level of the test tone by

dragging this control left or right.

You can also adjust the output level by rotating the round encod-

er knob on the actual DM-RTA device.

7. Output Level Value – Alternatively, you can adjust the test tone

output level by entering a numeric value here.

8. Output Level Mute – You can quickly turn the test tone output

on and o by clicking here, without changing the level value.
