3. With the speakers positioned upside down, mount the stands to the speakers using the thumbscrews, notating the direction of the speakers.
   1. The front of the speakers should be oriented to the front of the stand if you need to angle the speakers up. If you need the speakers to angle down, then orient the front of the speakers to the rear.

7. If you are using the Bluetooth option, push the Bluetooth button on the rear of the left speaker to enable pairing, and pair to your source device according to your device's instructions.
8. If you are using the USB input (GoAux 4 only); ensure that you select it as your audio output in the sound settings of your computer or DAW.
9. Play an audio track from your source and slowly bring up the volume of the source device (mixer, audio interface, or computer) to the desired listening level; Then, use the volume knob on the front of the left speaker to further adjust the level.
10. If you have a GoAux 4 and want to use the Automatic Room Correction feature, please see the AUTO ARC SETUP section.

PLACEMENT

Ensure that you place the monitor with the power and input connections on the left side. Download and use the free KRK Audio Tools app for the next steps. The left and right studio monitors should be approximately 1 to 1.5 meters (3 to 5 feet) apart and directed at a 60-degree angle towards the listening location. Measure the distance between the left and right studio monitors and note that the listening position is the same distance to both sides. This will form an equilateral triangle. It is important that both left and right studio monitors are level matched.

The GoAux monitor series are a two-way studio monitor with a tweeter (producing high frequencies) and a woofer (producing mid and low frequencies) in one enclosure. The midpoint between the tweeter and woofer is the acoustic axis. Ensure the acoustic axis is pointed to ear level in the listening position. Use the tilting mechanism integrated into the isolation stands to orient the acoustic axis to the correct position.

AUTO ARC SETUP

GoAux 4 only
Ensure that you have completed the PLACEMENT section before beginning.

1. Attach the included microphone to the microphone input on the front left of the monitor.
2. Position the microphone at ear level in your ideal listening position.
3. Push and hold the Auto ARC button on the rear of the left speaker.
4. The speakers will produce a series of 25 tones then repeat; this may last several minutes. Do not move the microphone during this time.
5. When the test is complete, a quick low frequency tone will indicate that the Auto ARC is finished.

You can now disconnect and store your microphone in the carry bag.
