3. If RCA connection is not possible connect as sketch K.
4. SUBWOOFER OUTPUT connect to subwoofer speaker as sketches L = total impedance
2 - 8 ohms, M = total impedance 2 - 4 ohms, N = total impedance = 4 - 8 ohms. The amplifier
delivers the highest power at 2 ohms. The sound and overload safety are the best at 8 ohms.

A-400 HIGH INPUT
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 with STANDBY ON
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. STANDBY LED: lights at standby mode
14. STANDBY OFF: amplifier is always on with POWER ON
15. STANDBY ON: amplifier switches on immidiately with input signal and switches
automatically back into standby mode after 30 seconds without signal
16. LEVEL SUB: 7=no sound, 5=maximum input sensitivity
17. HIGH CUT: cuts high frequencies above 7=40Hz, 8=55H, 9=65Hz, 10=70Hz, 11= 75Hz,
12=77Hz, 1=80Hz, 2=90Hz, 3=110Hz, 4=125Hz, 5=150Hz
18. BOOST LEVEL: increases the level at 7=0dB, 8=0.5dB; 9=0.8dB, 10=1dB, 11=2dB, 12=2.5 dB, 1=3dB,
2=4dB, 3=4.5dB, 4=5dB, 5=6dB
19. BOOST FREQUENCY: sets the BOOST frequency at 7=20Hz, 8=22Hz, 9=23Hz, 10=25Hz, 11=30Hz,
12=35Hz, 1=35Hz, 2=40Hz, 3=45Hz, 4=50Hz, 5=55Hz
20. EQUALIZER LEVEL: reduces the level at the frequency set by EQUALIZER ,FREQUENCY at 7 = 0dB, 8 =
0.5 dB, 9 = 1 dB, 10 = 1.8 dB, 11 = 2.5 dB, 12 = 2.5 dB, 1= 3,5 dB, 2 = 4 dB, 3 = 4.5 dB, 4 = 5 dB, 5 = 6 dB
21. EQUALIZER FREQUENCY: adjusts the narrow bandwith decrease at 7=22 Hz, 8=30Hz, 9=40Hz,
10=43Hz, 11=50Hz, 12=65Hz, 1=70Hz, 2=72Hz, 3=75Hz, 4=78Hz, 5=80Hz
22. SUBSONIC: filters unwanted lowest frequencies below 7=15Hz, 8=16Hz, 9=18Hz, 10=19Hz, 11=21Hz,
12=24Hz, 1=28Hz, 2=30Hz, 3=33Hz, 4=37Hz, 5=40Hz,
23. 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.
24. SAT OUT: limits the lowest frequency of the satellite speakers at 7=50Hz, 8=55Hz, 9=60Hz, 10=65Hz,
11=70Hz, 12=80Hz, 1=90Hz, 2=100Hz, 3=110Hz, 4=130Hz, 5=150Hz.
