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.

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.
• This device uses a BTL (Balanced Transformer-Less) connection method for the amplifier output. As the amplifier output
is sent to the positive and negative connectors, any contact with other terminals or the device chassis may lead to
malfunction.
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

Precautions for Rack Mounting
This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When
mounting the unit with other MA2120 unit(s) or other device(s) in an EIA standard equipment rack,
inter
nal temperatures can exceed the specified upper limit, resulting in impaired performance or
failure. When rack mounting the unit, always observe the following requirements to avoid heat buildup:
•
•
When mounting the unit in a rack with devices such as power amplifiers that generate a significant
amount of heat, leave more than 1U of space between the MA2120 and other equipment. Also either
leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility
of heat buildup.
To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters
fr
om walls or other surfaces. If the rear of the rack can’t be left open, install a commercially available
fan or similar ventilating option to secure sufficient airflow. If you’ve installed a fan kit, there may be
cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack
and/or fan unit manual for details.

WARNING
Always follow the basic precautions listed below to avoid
the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, re or other hazards. These
precautions include, but are not limited to, the following:
Power supply/power cord
• Do not place the power cord near heat sources such as
heaters or radiators, and do not excessively bend or otherwise
damage the cord, place heavy objects on it, or place it in a
position where anyone could walk on, trip over, or roll anything
over it.
• Only use the voltage specified as correct for the device. The
required voltage is printed on the name plate of the device.
• Use only the supplied power cord/plug.
If you intend to use the device in an area other than in the
one you purchased, the included power cord may not be
compatible. Please check with your Yamaha dealer.
• Check the electric plug periodically and remove any dirt or
dust which may have accumulated on it.
• When setting up the device, make sure that the AC outlet you
are using is easily accessible. If some trouble or malfunction
occurs, immediately turn off the power switch and disconnect
the plug from the outlet. Even when the power switch is turned
off, as long as the power cord is not unplugged from the wall
AC outlet, the device will not be disconnected from the power
source. When installing in a rack, connect a power cut-off
device additionally to power off the device handily.
