Determines the base volume for channels 3/4. Set this to LOW (O) if the [SIG/PEAK] LED keeps lighting up red or if
the sound is distorting.

NOTE

Turn the channel faders to the minimum setting before you toggle the [GAIN HIGH/LOW] selector switch. This is because you may hear
a noise when the switch is toggled.

Streaming a conversation on your smartphone via computer

When you want to stream the conversation you’re having on your smartphone via the computer (such as
when guests are participating via phone call), use a 3.5 mm four-conductor (TRRS) stereo mini cable to
connect the [LINE 7/8 IN/OUT] smartphone input/output jack to the headset jack on your smartphone
(iPhone, Android device, etc.).

The default output setting for the smartphone input/output jack is AUX, which prevents the other party’s
own voice from looping back to them when you are making a smartphone call.

NOTE

You will need a conversion adapter cable if your smartphone does not have a jack for connecting stereo mini plugs. For example, for
Android devices that use a USB-C port to input/output audio, you’ll need a USB-C to 3.5 mm four-conductor (TRRS) earphone jack
conversion adapter cable. For iPhones equipped with a Lightning connector, you will need a Lightning to 3.5 mm Headphone Jack
Adapter.

Troubleshooting

Power-related

The power LED will not light up

Is the power of this product turned on?

(

The LED will not light up if this product is not turned on.

(

This product must be supplied power from the included AC adapter. Connect the included AC adapter
to the [12V] DC jack on the rear panel.

The power LED is flashing, or lights only intermittently

There might be a problem with the power supply.

(

(

The LED flashes when there is some kind of problem with the power supply. Connect the included AC
adapter to the [12V] DC jack on the rear panel.

Are you using the appropriate USB cable?

(

(

Make sure to use the included USB cable.

(

For iPads/iPhones with a Lightning connector: an Apple Lightning to USB 3 Camera Adapter and a
commercially available USB-A to USB-C cable is required.

Troubleshooting > Audio-related and other issues

Audio-related and other issues

Your computer (Windows PC/Mac) does not recognize this product

Have you installed the driver?

(

You must install the Yamaha Steinberg USB Driver if you wish to connect this product to a computer
(Windows PC/Mac).

(

Refer to the following website for how to install the Yamaha Steinberg USB Driver.

No sound is heard

Are you using the appropriate settings for the [STREAMING ON/OFF] switch?

(

Are any external devices (such as a mic) or powered monitor speakers connected correctly?

(

Are the connecting cables shorted out or otherwise disconnected?

(

Have you turned on the power of any connected electronic instruments or powered monitor

(

speakers?

Are the [GAIN] knob, the faders, the [MONITOR] knob and the [MONITOR PHONES] [H] knob

(

adjusted appropriately?

Is the [LINE/USB] selector switch set correctly?

(

Is the [GAIN HIGH/LOW] selector switch set correctly?

(

(

Set the switch to [HIGH]. If the volume from the sound source is too low, you may not be able to hear
the sound when this switch is set to [LOW].

Is the [MIX MINUS] switch turned on?

(

If you are using Internet livestreaming software, have you adjusted the volume in the software?

(

Sound is distorted or noisy

Is the channel [SIG/PEAK] LED lit up red?

(

(

Try lowering the [GAIN] knob and turning the [PAD] switch on.

Are the [OVER] indicators (red) on the STREAMING OUT LED level meters lit up?

(

(

Adjust the fader for each channel. [OVER] does not go dark on the STREAMING OUT LED level meters,
even though the volume is turned down on the [MONITOR] and [MONITOR PHONES] [H] knobs.

Are the levels set too high on the devices connected to this product?

(

(

Lower the volume of the connected devices.

Is the [LINE/USB] selector switch set correctly?

(

Is the [GAIN HIGH/LOW] selector switch set correctly?

(

Set the switch to [LOW]. If the volume from the sound source is too high, the sound may distort when
the switch is set to [HIGH].

73

Troubleshooting > Audio-related and other issues

Making the vocals or speech sound clearer

Set the [COMP EQ] button to on (the button lights up orange).

(

(

A parameter that’s appropriate for Internet livestreaming is already set for this button by factory
default, which keeps down unnecessary noise in the low end and helps smooth out differences in the
input levels.

Reverb is not applied

Is the FX effect type for channel 1 set to REVERB?

(

Troubleshooting > Restoring the product to factory default settings (initialization)

Restoring the product to factory default settings
(initialization)

Follow the steps below to initialize and restore the product to its factory default settings. This initializes all of
the settings including the parameters you modified using the AG08 or the AG08 Controller app, the CH1
PRESET data, the SOUND PAD audio data and so on.

1 Set the [z] (standby/on) switch to standby for the time being.
2 Set the [z] (standby/on) switch to on while holding down the [COMP EQ] button

for channel 1.

All of the LEDs on the top panel flash twice, and initialization begins. Wait until the LED light animation is
finished. Initialization takes about 50 seconds.
