A-801 Amplifier for Subwoofer and Bass Shaker
Compared to the A-800, the controls are front and extended by variable bass relief / SUBSONIC . The proven strong analog power supply with the 1000 Watt toroidal transformer is combined with a digital final amplification. Softstart relays enable operation with a standard 16A home fuse.
For large seating areas with 2 separable elements, 2 x BS-200i structure-borne sound transducers / bass shakers are required per element. The high power reserve of the A-801 enables strong and precise vibrations. The same applies to 4-6 separate armchairs or a platform up to 500 kg total weight with persons.
A slight vibration of the transformer cannot be avoided as the huge toroidal transformer (approx. 5 kg) cannot be installed completely insulated. However, this can only be heard up to 0.5 metres away and by no means from the loudspeakers.
For house network interferences, please use the GND/ LIFT switch on the rear panel.

LEVEL SUB controls the input sensitivity / volume. The SUBWOOFER output of the AV receiver or other music sources should be set to approx. + 80% to send a strong, clean signal to the A-801 INPUT L or R or both (for stereo subwoofer outputs).
SUB OUT - HIGH CUT limits the frequencies above 40 - 300 Hz. For structure-borne transducers we recommend 50-70 Hz = control position 8-10:00 for movies. For games / car racing you can set to 10-12:00.
SUBSONIC: For music with a lot of low bass, turn slowly from the very left to the right until the low bass or the vibration of the structure-borne sound transducer becomes slightly weaker, then again 3-4mm to the left = reactive power is filtered = more useful reserve.
If you turn the subsonic control further to the right, you can mechanically and electrically relieve small subwoofers.
A manual or automatic boost with measuring systems of the falling low bass is not necessary, without additional 5-fold amplifier reserve. The lowest octave of 20-40 Hz requires more than 70% of the total power. In this range it is not a question of subtleties, but of sheer power = fast, strong current delivery for impulse fidelity in low bass even at very high power levels.
If only one subwoofer RCA output is available on the AV receiver, this can be doubled with the enclosed Y-adapter. A Cinch mono cable then leads to the amplifier INPUT L or R.
Power for up to 6 x BS-200i:
For large seating areas with 2 separable elements you need 2 x BS-200i per element. The high power reserve of the A-801 enables strong and precise vibrations, as well as 4-6 separate armchairs or a platform up to 500 kg total weight with persons.

Super Kombi

Habe dieses Set mit dem 801 und zwei Shakern BS200 seit zwei Wochen im Einsatz. Die Shaker in Kinosesseln montiert und trotz der vielen Umlenkhebel/ Ausziehmechanismus erreicht man ein 4. Dimension im Kino. Ich war vorerst skeptisch, ob ein nicht starr verbundenes Untergestell mit dem Sesselpolster die Vibrationen überhaupt produzieren / übertragen kann.

Das Ergebnis ist erstaunlich. Der Verstärker ist so fein justierter, dass geringste Basssequenzen sehr sauber synchronisiert mit dem Filmgeschehen dargestellt werden. Das System hat bei 2 BS200 noch dermaßen Reserven, dass bei Pegeleinstellungen im SUB Level /„Lautstärke“ von nur 20% (den Sub LFE am AV auf 80% gestellt) das Bodyshaker Ergebnis vollkommen ausreichend ist.

Absolut Daumen hoch
