WORK WITH AN INPUT SIGNAL OF
300MV TO 1 VOLT. TO INCREASE THE GAIN,
MOVE THE JUMPER TO THE +20 dB POSITION. TO DECREASE INPUT GAIN,
PLACE JUMPER IN THE 0, -10, OR -20 dB POSITION.
➂ INSTALL ACCESSORY MODULES. AT YOUR BENCH, ADJUST
CROSSOVER MODE JUMPERS AND CHANGE CROSSOVER FREQUENCY
SIP’S .

NOTE: –20 dB = 10V – 17V IS ONLY TO BE USED WITH BALANCED INPUT FROM A BALANCED SOURCE. (IE: FOATING GROUNG OUTPUT)
–20 dB = 10V – 17V
–10 dB = 3V – 8V 0 dB = 1V – 3V +10 dB = 300mV–1V +20 dB = 100 – 300mV
BALANCED INPUT: TO ENABLE THE BALANCED LINE, PLACE
THE JUMPER ON THE LEFT AND CENTER SET OF PINS
