A-409 Subwoofer Mono Amplifier 1 x 400 W / 2 Ω Subwoofer Amplifier
with complete Frequency and Room Adjustment

You want to use your subwoofer(s) optimally? This is the right amplifier for it!

 

The A-409 is a very efficient amplifier for subwoofer operation with high quality, power and various frequency controls. This 400 Watt mono amplifier is almost alone on the market.
The 2 Ohm capability enables the parallel operation of e.g. two 4 Ohm subwoofers.
In the power range a strong 500 Watt toroidal transformer was used and the resilient TOSHIBA end transistors allow a higher pulse power up to 485 Watt. Designed and manufactured with SMD circuit board in the preamplifier and partial SMD in the output stage, the A-409 is state of the art. The high operational reliability is guaranteed by various protective circuits. The heat loss is dissipated via the anodised cast aluminium housing (designed as a heat sink).

The following is available for extensive settings:
LEVEL SUB = adjustment of subwoofer volume, HIGH CUT = upper bass frequency, BOOST LEVEL = bass boost strength, BOOST FREQUENCY = bass boost frequency range, EQUALIZER LEVEL = bass cut strength, EQUALIZER FREQUENCY = bass cut frequency, SUBSONIC = low bass filter starting point, PHASE = phase shift starting point, LOW CUT = lower frequency of satellite speakers starting point, LOW CUT = lower frequency of satellite speakers starting point, LOW CUT = lower frequency of satellite speakers starting point, EQUALIZER LEVEL = lower frequency of satellite speakers starting point, EQUALIZER FREQUENCY = lower frequency range of bass cut, EQUALIZER LEVEL = lower frequency of bass cut, EQUALIZER FREQUENCY = lower frequency of bass cut starting point, PHASE = lower frequency of satellite speakers starting point, LOW CUT = lower frequency of satellite.
