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.
NOTICE
• Match the impedance settings of this device and the connected speakers. Use in which the impedance does not
match may cause damage to the device or speakers.
• 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.
• Connectable cable gauges: AWG20 (0.5mm
2
) to AWG16 (1.3mm
2
)

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 rotate the [VOLUME] knob.
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” to adjust the volume level of 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 ashes.
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.

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.

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.
NOTICE
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.
• Recommended cable gauges for the Euroblock plug: AWG26 (0.13mm

) to AWG16 (1.3mm
2
)
• 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.

Securely tighten terminal screws.
4
Insert the Euroblock plug into the [MIC IN 2] terminal of MA2030a or the [LINE IN]
terminal of PA2030a.
Switching the panel lock on/off
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
Press the [ST SOURCE] knob three times within a second.
3
To set the panel lock off, press the [ST SOURCE] knob three times within a second
again.
