AM II
Adaptive MOSFET II is an advanced protection circuit
designed to prevent amplifier shut-off due to low load imped-
ance. AM II optimizes output power to maintain uninterrupted
operation whenever the amplifier senses a load impedance of
less than two Ohms. An L. E. D. signals when AM II is working,
Bridging:
Combining two amplifier channels into one channel, typically
used to create a mono output.
Gain:
The ratio of output voltage to input voltage. The gain control
allows adjustment to the amplifier's output level for varying
input levels.
L.E.D.:
Light Emitting Diode. Indicates power on / off and when AM II
is working.
Load Impedance:
Measurement of speaker(s) resistance / reactance that the
amplifier must drive.
Mixed Mono:
The amplifier's ability to play the Left and Right Stereo channels
while playing a third (bridged) mono channel.
PWM
Pulse-Width Modulated power supply. Our PWM maintains a
regulated output voltage and a high conversion efficiency over
the input supply range of 11 - 15 VDC. The result is less demand
on the battery, lower (amplifier) operating temperature, and
extremely accurate low frequency reproduction.
Remote Turn-On:
Low current automatic switching circuit that turns the amplifier
on and off. Typically connected to the remote antenna or amp
turn-on lead of most car radios, cassette, or CD players.
