2. GENERAL DESCRIPTION
TOA's SR-M3L and SR-M3R stage monitor speakers are especially designed for touring applications.
They feature high sound quality, high power handling capacity, and robust construction that protects the unit
from damage during transportation and setup.
3. FEATURES
• Both the SR-M3L and SR-M3R are single-amp driven speaker systems with passive internal networks.
The speakers can also be easily converted to "biamp" operation by changing the unit's internal wiring.
• Internal 38 cm woofer having a large 20 cm magnet
• The tweeter features a large, high-power driver, a titanium diaphragm, and a 40° horizontal x 60° vertical
constant directivity horn.
• Neutrik NL4MP connectors are used to facilitate and ensure tight cable connections. Two Neutrik connectors
are provided to permit parallel speaker connections.
4. NEUTRIK CONNECTORS AND THEIR WIRING DIAGRAM
• The Neutrik input connectors are shown at right.
Because both connectors are internally connected in parallel,
either connector may be used for connection.
• For wiring of the NL4MP connector pins, refer to the table on
the right.
• The Neutrik connector (on the cable side) that can match to
the NL4MP is the NL4FC.

When the Unit is in Use
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
• Do not stand or sit on, nor hang down from the unit
as this may cause it to fall down or drop, resulting
in personal injury and/or property damage.
