Owner's Manual

3. 1/4" TRS Line-Level Input and Output – These are balanced con-

nections for line-level analog signals. The line-level 1/4" TRS out-

put from your equipment can connect here, so the DM-RTA will re-

ceive the line-level audio signals for analysis. The line-level analog

output from the DM-RTA connects to the line-level inputs of your

power ampliers and other equipment.

4. Options Port – This port allows you to connect our optional

Bluetooth adapter, so you can stream audio into the DM-RTA from

your Bluetooth-enabled devices. Further details will be available

when this accessory and others become available.

5. RCA Line-Level Inputs and Outputs – These are unbalanced

stereo RCA connections for line-level analog signals. The line-level

output from the head unit or factory-installed radios can connect

here, so the DM-RTA will receive the line-level audio signals for

analysis. The line-level analog outputs from the DM-RTA connect

to the line-level inputs of your power ampliers and other equip-

ment.

6. Stereo Speaker-Level Inputs – The speaker-level output

from ampliers and factory installed radios can connect

here, so the DM-RTA will receive the audio signals this way

and do its thing. Make sure that you follow the plus and mi-

nus polarity markings on the DM-RTA and match it to the

polarity of the speaker wiring. Analog signals entering the

DM-RTA are the sum of the speaker-level inputs and the other

inputs.

7. Coaxial and Optical Digital and USB Outputs – These S/PDIF

and Toslink inputs allow you to connect the digital audio output

from the DM-RTA to your other equipment.

8. Rotary Push-Encoder – This control is used to adjust the Test

Tones from the DM-RTA. Press the control to increment through

octaves, and rotate it to control the level.

9. Mounting Holes – These holes are used for mounting the DM-RTA

securely, if for example, you want to install it as part of handy test

cart.
