AM II
Adaptive MOSFET II is an advanced protection circuit
designed to prevent amplifier shut-off due to low load imped-
ance. AM III 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.
The following terms are used in this manual. Since they may be unfamiliar, the
following definitions are provided.
ACM
Amplifier Control Module. Our ACM-420 (optional) controls up
to ten PPI amplifiers for synchronized system start and "noise
gate" functions to inhibit background noise when no music
signal is present
