Step 

1

Change the setting depending on the speaker connection (high- or low-impedance connection), the kind 

of speakers, and the installation location of the speakers. Refer to “Connecting Speaker Cables” at the 

right bottom on this page and the explanation of high-impedance connection, etc. at the following URL.

Yamaha Pro Audio site: “Better Sound for Commercial Installations”:

http://www.yamahaproaudio.com/global/en/training_support/better_sound/

 Caution

•  Before connecting speakers, make sure that the power of the device is turned off. If the power is on, there is a risk of 

electrical shock.

•  Ensure that load is not applied to the speaker cable.

•  In a high-impedance installation, make sure that the sum of the power input ratings of the speakers to be connected 

does not exceed 60W.

•  In a low-impedance installation, make sure that the total impedance of speakers to be connected is at least 3 ohms. 

■

High-impedance Connections (60W x 1 channel)

voltage: 70V

1 

Set the speaker output to high-impedance by setting the [OUTPUT] switch to 

[100V] or [70V] corresponding to the maximum output voltage.

Use speaker cables to connect the [SPEAKERS A] 

 terminal to the positive “+” 

terminals of the speakers, and the [SPEAKERS B] 

 terminal to the negative “-” 

terminals.

In case of high-impedance connection, the [SPEAKERS A] 

 and [SPEAKERS B] 

 terminals are 

not used. Do not connect to the terminals.

Note

  The speaker output is processed through a high pass filter (80Hz, 18dB/oct.).

1 

Select a stereo input by rotating the [ST SOURCE] knob. 

The [ST SOURCE] indicator corresponding to the selected input signal lights.

2 

Input audio signal from the external device, and confirm that sound is being output 

from the speakers by gradually rotating the [VOLUME] knob to the right.

Make sure that the [VOLUME SIGNAL] indicator lights according to the sound input and that sound 

comes from the speakers.

Matching the volume levels of external devices (including microphones) 

When connecting two or more external devices, you can lower the volume of the louder devices (or 

microphones) to match the level of the faintest device. If you are using microphones, follow the instructions in 

“Option 1 Using Microphones” before executing the operation below.

1 

Select the stereo input with the loudest sound by rotating the [ST SOURCE] knob.

2 

Press and hold the [ST SOURCE] knob until the [ST SOURCE] indicator flashes.

3 

Rotate the [ST SOURCE] knob to the left until the volume decreases to the point that 

lowers as loud as that of the faintest sounding stereo input (or microphones).

As the volume becomes fainter, the flashing rate of the [ST SOURCE] indicator becomes slower.

4 

Push the [ST SOURCE] knob to complete the adjustment.

The [ST SOURCE] indicator lights.

Note

  Adjustable range: -18dB – 0dB

Using Microphones

1 

Turn the [MIC IN 1] knob or the [MIC IN 2 GAIN] trimmer all the way to the left, and 

connect a microphone to the [MIC IN 1] jack or the [MIC IN 2] connector.

2 

Set the [VOLUME] knob to roughly a 2:00 position.

3 

Loudly speak into the microphone, and turn the [MIC IN 1] knob or the [MIC IN 2 GAIN] 

trimmer to the right until the output signal is not distorted.

If you input a loud voice but the output is small, raise the volume with the [VOLUME] knob.

If the sound out of the speakers is too loud, lower the volume with the [MIC IN 1] knob or the [MIC IN 2 

GAIN] trimmer.

4 

Make sure the input from external devices matches the volume levels of the 

microphones and the external devices.

Refer to “Matching the volume levels of external devices (including microphones)” in “Step 4 Adjusting 

Volume” for instructions.

Note

  •  To adjust the [MIC IN 2 GAIN] trimmer, use a slotted screw driver.

•  Refer to “Attaching Euroblock Plugs” for installation of Euroblock plugs.

•  The input signal is always processed through a high pass filter (120Hz, 12dB/oct.) to cut off low frequency signals 

as well as a Feedback Suppressor to suppress howling.

•  Activating the Ducker lowers the output volume of 

the stereo inputs by 24dB and mutes that of the 

other microphone input.

Connecting Speaker Cables

The [SPEAKERS] output connectors on the rear panel are barrier strip type connectors. The connections 

are described below for two methods: using a spade lug and using a bare conductor.

 Caution

Ensure that load is not applied to the speaker cable.

Note

  Connect the cables so that the amplifier’s “+” and “-” symbols match those of the speaker. If they are reversed, 

the phase will be reversed and the sound will not be output correctly.

When using a spade lug

Loosen the screw, insert the spade lug all the 

way from below, and tighten the screw.

≤5.8mm

(≤0.23")

≥3.2mm

(≥ 0.13")

When using a bare conductor

Loosen the screw, wrap the conductor wire around 

the barrier strip terminal, and tighten the screw. Be 

sure that the bare wire does not touch the chassis.

Note

  •  You must use the supplied Euroblock plugs. If the plugs have been lost, please contact your Yamaha dealer.

•  To prepare the cable for attachment to a Euroblock connector, strip the wire as shown in the illustration using 

stranded wire to make connections. With a Euroblock connection, stranded wires may be prone to breakage 

because of metal fatigue due to the weight of the cable or due to vibration. When rack mounting your device, 

use a lacing bar when possible to bundle and fasten the cables.

•  Do not tin (solder) the exposed end.

3 

Securely tighten terminal screws.

4 

Insert the Euroblock plug into the [MIC IN 2] terminal of MA2030 or the [LINE IN] 

terminal of PA2030.

Panel Lock

Changes by several knobs can be locked, so that the settings of the device are not affected by accidental 

touch or unauthorized operation. The [ST SOURCE], [SOURCE EQ BASS] and [SOURCE EQ TREBLE] 

knobs can be locked.

1 

Adjust the [ST SOURCE], [SOURCE EQ BASS] and [SOURCE EQ TREBLE] knobs 

to the desired fixed settings.

2 

Turn off the power.

3 

Set DIP switch 8 to the downward position.

4 

Turn the power back on again.

Note

  To unlock, turn off the power, set DIP switch 8 to the upward position, and turn on the power.
