l

Designed for use in a wide variety of PA applications.

l

SSA-10000 is a 1000 Watts Mixer Amplifier with Eight Unbalanced 

Mic  inputs.  Four  are  independent  Mic  Inputs  and  Four  Mic  inputs 
alternate to Four Auxiliary inputs selectable through slide switches. 
Fourth Auxiliary input is provided with RCA Socket for connecting CD 
Player.

l

SSA-10000 has a Preamp output for recording the program, a Line 

output  for  connecting  to  a  Booster  Amplifier  and  a  Line  input  for 
connecting to an external  PA  Audio Mixer.

l

Box  Speaker/  Driver  Unit  selector  switch  has  been  provided  for 

protecting  the  Driver  Unit's  diaphragm  from  unwanted  low 
frequencies. Since Box speakers can reproduce the full spectrum of 
audio  frequencies  but  Driver  Units  cannot  reproduce  very  low 
frequencies, the switch should be positioned to the Driver Unit side 
when Driver Units, Horns and Column speakers are connected.

l

Circuit Protector Device in place of AC fuse & DC circuit breaker (MCB 

type)  have  been  provided,  these  safeguards  the  amplifier  against 
overload and  short circuit. 

l

Provision  for  automatic  changeover  from  AC  to  Battery  Operation 

ensuring continuity of program has been provided.

l

Protection  provided  against  the  reverse  polarity  of  Battery 

connections. 

l

Ease  of  operation,  combined  with  service  accessibility  has  been 

optimized in the design.
