General Description
The SF112A and SF115A are 2-way powerful and reliable loudspeakers. With
its high-current capacity ampliers, high-output 1.75” titanium diaphragm
compression driver, and special magnet heat radiator woofer, they produce an
even smoother sound than the original. Our design goal was to build a sound
reinforcement speaker with:
• High output, most reliable and accurate playback.
• Very wide, smooth dispersion of mid and high frequencies.
• Light weight and ergonomical design for easy transport.
Through the combined resources of our analog engineers, and our experienced
transducer engineers, and the the result is a highly impact sound reinforcement
system which will amaze your hearing experience.

1. IEC POWER SOCKET
Before connecting to the AC outlet, make sure the voltage is
same as required.
2. POWER SWITCH
This switch will determine the SF Series speaker where on or
off. Make sure the level control is down before you turn it on.
3. ON indicator
This green indicator lights on when power is turned on and it
goes off when power is off.
4. MIC/LINE level control
This knob determines the input level (microphone or line
inputs) to be sent to built-in power amplier.
5. LOW CUT FILTER
This Pushing in this switch engages a low-cut lter, which
rolls off 12 dB per octave at the low frequencies below 100
Hz. This is useful for minimizing stage noise (rumble) and
microphone handling noise. It is highly recommended that
you engage this switch when using the SF speaker as a stage
monitor. This allows the bass amplier to utilize its power for
those frequencies useful in stage monitor applications.
6. MIC/LINE SWITCH
Press down this button and the INPUT jack is for microphone
input source, and release this button the INPUT jack is for
line source, like mixer or signal processors.

8. SIGNAL INDICATOR
When input level gets to -40dBu, then this indicator will be on
to inform the user there is input signal sent in.
9. LF LIMITER
When built-in LF power amplier is overloaded, the builtin limiter circuit will be engaged to the audio path to prevent
speaker damaged by over-drive or excess signal level. This
indicator will keep on when LF limiter is triggered.
10. HF LIMITER
When built-in HF power amplier is overloaded, the builtin limiter circuit will be engaged to the audio path to prevent
speaker damaged by over-drive or excess signal level. This
indicator will keep on when HF limiter is triggered.
11. XLR INPUT JACK
This is a female XLR-type connector that accepts a
balancedor unbalanced mic- or line-level signal.
12. XLR LOOP THRU JACK
This is a male XLR-type connector that produces exactly the
same signal that is connected to the INPUT jack. It can be
a balanced or unbalanced mic- or line-level signal. Use it to
daisy-chain several active speakers together off the same
signal source.
7. MIC/LINE INDICATOR
When MIC/LINE SWITCH (no. 6) is pressed down, this
indicator will be lighted up, and the VOLUME CONTROL
(no. 4) is for microphone input. When it is off, then VOLUME
CONTROL (no. 4) is for line source.
