9. JOINING SPEAKERS
Two linear speakers can be linked to each other using the optional SR-EP3 Extension plate.
Joining line array speakers configures a longer linear sound source, permitting transmission of higher sound
output over a longer distance.
Notes
• Linkage is only possible for the following two speaker combinations, and cannot be performed for any other
combinations:
SR-H3L + SR-H3L
SR-H3L + SR-H2L
• When linking, position the lower speaker upside down.
Step 1. Of the screws on the speaker rear (SR-H2L or SR-H3L), remove the lower four M5 flat-head screws.
The removed screws will no longer be used.
Step 2. Attach the SR-EP3 Extension plate to the rear of the two speakers with its supplied screws.

Note
When linking the SR-H3L to the SR-H2L, if the same input voltage is applied
to both speakers, a difference in sound pressure between the two will result.
For this speaker combination, it is highly recommended that each speaker be
driven by a separate amplifier.

Speaker unit x 9
SR-H3L
Speaker unit x 16
Setting the SR-H2L’s volume 2.5 dB
lower than that of the lower SR-H3L
will cause the 25 speaker units to
produce the same sound volume.
