Features
Your Atlantic Technology Powered Subwoofer was engineered using the latest
technology and finest components available.
● High excursion drivers in a sealed acoustic suspension cabinet
● Continuous power output conservatively rated at 125, 150 and 200 watts
(Model 222, 262, and 352, respectively) Coupled with our highly efficient drivers,
this is plenty of power for even the most dynamic music and effects you are likely
to encounter.
● Discrete very high current output devices rated at 30 amps each
The 352 PBM THX doubles up output devices for even higher current capability.
● Working frequency range from 20Hz to low pass filter setting up to 125Hz
● Continuously adjustable low-pass filter from 60Hz to 125Hz
The slope of the low-pass filter is -24 dB/octave. This allows for flexible integration
with most any brand or type of speaker on the market.
● Two line input and two passive line level outputs with gold RCA connectors
The model 352PBM THX uses one line input as the THX input to comply with
THX requirements.
● All speaker inputs and outputs are gold 5-way binding posts
This is the ideal way to make connections without compromising signal integrity.
All models employ a 12dB/octave subsonic filter for frequencies below 20Hz.
Frequencies below 20Hz are inaudible and consume vast amounts of amplifier
power. Filtering them out with a gradual slope maintains amplifier headroom
while maintaining fidelity.
● Phase inverter toggle switch (0/180°)
Allows matching with many systems whose output may be inverse phased.
● Woofer output level control
Matches a wide range of input levels.
● Optical anti-clipping circuitry
This is the lowest distortion type of circuit available. It has ideal linearity, works in
real time and uses imperceptible time constant triggers (delays) so that its effect
during operation, if needed, is virtually instaneous and inaudible.
● 75°C thermal protection
Temperature at external surface of heatsink never goes above 70°C. The output
devices are rated to operate safely at much higher temperatures.
● Auto power on/off function
The 7-10 minute turn-off delay features a front panel mounted dual-color LED
power indicator for power on and standby indication.
