Connecting Speakers

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.

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)

Maximum output

voltage: 100V

voltage: 70V

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]

not used. Do not connect to the terminals.

Note

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

■

Low-impedance Connections (30W x 2 channels)

Speaker impedance

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

to [4Ω 3Ω].

Set the [SETUP] DIP switch 1 to [4Ω] (up, impedance: 4Ω or more) or [3Ω] (down,

impedance: 3Ω to 4Ω) corresponding to the specifications of the speakers to be

connected.

Connect the [SPEAKERS A]

terminals to the "+"/"-" terminals of the first

speaker, and the [SPEAKERS B]

terminals to the "+"/"-" terminals of the second

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.

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

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

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.

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

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.

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.

Ensure that load is not applied to the speaker cable.

Note

• If both Duckers of the [MIC IN 1] jack and the [MIC

Connecting Speaker Cables

Caution

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 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.

• 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.

Loosen terminal screws.

Insert cables.

Securely tighten terminal screws.

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

terminal of PA2030.
