30-SD
General Description
The 38-SD and 30-SD ar e compact, roadworthy 3-way speaker
systems with Thiele-Small aligned bass reflex enclosures
which house one 15" (38-SD) loudspeaker, one 12" (30-SD)
loudspeaker and a small-sized radial horn coupled with high
efficient compression driver and two (38-SD) or one (30-SD)
high performance tweeter They are designed to be used as
full range systems or with the use of the additional in/out 1/4"
phone jacks can be bi-amplified. They offer extended frequency response, exceptionally high power capacity (120W
continuous pink noise) and high efficiency They are ideal for
any sound reinforcement application that requires a blend of
outstanding performance and maximum portability TOA's
unique front-slotted design functions as an acoustic low pass
filter, obtaining a smooth crossover between low and high
frequency and ensuring f lat response. They are equipped wit h
the side-mounted handles fo r ease in carrying and set up. The
enclosures have metal grills to protect loudspeakers and
interlocking corners for vertical stacking of similar models and
an integral stand mounting adapter.

Connects to the output of power amplifier. This is
the input jack when used as a full range speaker.
Connects to the amplifier for high frequency when
driving the speaker system with bi-amplification.
Connects to the amplifier for low frequency when
driving the speaker system with bi-amplification.
Adjus ts the sound level of the mid-frequency when
driving the speaker system as a full range speaker
system. Make the level setting according to the
environmental conditions, although almost flat
frequency response is obtainable so far as the
attenuator remains within the "NORMAL" range.

FULL RANGE OUTPUT
Make bridge connection of this output to the full
range input of another speaker system when driving
two speaker systems with one power amplifier.
BI-AMP OUTPUT (HIGH)
For bridge connection in high frequency to another
speaker.
BI-AMP OUTPUT (LOW)
For bridge connection in low frequency to another
speaker.
CAUTION:
DO NOT USE THE BI-AMP JACKS UNLESS TH E
SPEAKER SYSTEM IS DRIVEN UNDER
MULTI-AMPLIFIERED SYSTEM. CONNECTING
THE FULL RANGE OUTPUT TO THE BI-AMP
