5. If the voltage printed at the back side (110 V or 230 V) is equivalent to your house voltage
connect AC INPUT with your house AC with the attached cable. Due to the high switch-on
power at least a 230V/10 amp (110V/20 amp) house fuse is needed.
6. Play your main amplifier at low level music with deep bass
7. POWER at On and LEVEL turn right until you hear sound from your subwoofer
8. At medium loudness adjust all knobs as shown below. The numbers are related to clocklike setting,
examples: 7 = 7 o'clock = far left, 12 = 12 o'clock = upright, 5 = 5 o'clock = far right
9. POWER OFF: amplifier is totally off = no electric power wasted
10. POWER ON: amplifier on = steady electric consumption 10 watts
11. PROTECT LED: lights up at faulty operation as too low speaker impedance / short cut,
overload, overheat
12. CLIPPING LED: a short light up indicates that overload starts but it is still tolerable at
very short bass impulses. At stronger light up reduce LEVEL. At speaker shortcut, too low
impedance and overload the relay cuts the speaker and the LED steady on. After about
every 10 seconds the circuit tests if the shortcut, low impedance or overload has been relieved.
13. LEVEL SUB: 7=no sound, 5=maximum input sensitivity
14. HIGH CUT cuts frequencies above 7=40Hz, 8=58Hz, 9=80Hz, 10=110Hz, 11= 150Hz,
12=180Hz, 1=200Hz, 3=240Hz, 4=260Hz, 5=300Hz
15. BOOST LEVEL: increases the level at 7=0dB, 8=1.2dB; 9=2.4dB, 10=3.6dB, 11=4dB,
12=5 dB, 1=6dB, 2=6.3dB, 3=6.5dB, 4=7dB, 5=7.5dB
16. BOOST FREQUENCY: sets the BOOST frequency at 7=15Hz, 8=18Hz, 9=20Hz, 10=30Hz,
11=35Hz, 12=40Hz, 1=45Hz, 2=47Hz, 3=50Hz, 4=53Hz, 5=55Hz
17. EQUALIZER LEVEL: reduces the level at the frequency set by EQUALIZER ,FREQUENCY at 7 = 0dB,
8 =1.2 dB, 9 =2.4 dB, 10 = 3.6 dB, 11 = 4 dB, 12 =5 dB, 1=6 dB, 2 =6.3 dB, 3 = 6.5 dB, 4 = 7 dB, 5 = 7.5 dB
18. EQUALIZER FREQUENCY: adjusts the narrow bandwith decrease at 7=17 Hz, 8=25Hz, 9=35Hz, 10=40Hz,
11=50Hz, 12=60Hz, 1=65Hz, 2=70Hz, 3=75Hz, 4=80Hz, 5=85Hz
19. SUBSONIC: filters unwanted lowest frequencies below 7=10Hz, 8=13Hz, 9=16Hz, 10=22Hz, 11=26Hz,
12=30Hz, 1=34Hz, 2=39Hz, 3=43Hz, 4=47Hz, 5=50Hz
20. PHASE: adjusts the subwoofer for same acoustical phase as the front speaker at the preferred listening
spot. Listening test for best mix of front speaker and subwoofer is essential.
21. SAT OUT: limits the lowest frequency of the satellite speakers at 7=30Hz, 8=36Hz, 9=60Hz, 10=97Hz,
11=126Hz, 12=150Hz, 1=200Hz, 2=280Hz, 3=310Hz, 4=357Hz, 5=400Hz.
