Model 38-SDM, 30-SDM
General Description
The 38-SDM and 30-SDM are compact, roadworthy 3-way
stage monitor speaker systems with Thiele-Small aligned bass
reflex enclosures which house one 15" (38-SDM) loudspeaker
one 12" (30-SDM) loudspeaker and a small-sized radial horn
coupled with high efficient compression driver and two
(38-SDM) or one (30-SDM) high performance tweeter They
are designed to be used as f ull 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 TOA's unique front-slotted design functions as an
acoustic low pass filter obtaining a smooth crossover between low and high frequencies and ensuring flat response.
The enclosure's have side-mounted handles for ease in ca rr y -
ing and set up, and metal grills to protect loudspeakers.
Features
1. Extended frequency response
2. High power capacity of 120 watts continuous pink noise
(Test duration: 24 hours)
3. Slotted design that functions as an acoustic low pass filter
4. Side-mounted handles for ease in carrying
5. Input jacks fo r bi-amplification

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.
30-SDM
Adju sts 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.

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
INPUT JACK MAY DAMAGE THE SPEAKER.
