glossary
The following terms are used in this manual. Since they
may be unfamiliar, the following definitions are provided.
Bridging:
Combining two amplifier channels into one channel.
Typically used to create a high-powered mono output.
Gain:
The ratio of output voltage to input voltage. The gain on
the M Series amplifiers has two different areas of adjust-
ment. The input gain jumper offers 40 dB of input gain
adjustment while the front panel potentiometer offers 15
dB of amplifier output level adjustment.
LED:
Light Emitting Diode. The M Series uses 3 colored LED’s
to indicate the operational status of the amplifier. A RED
LED for power on/off, YELLOW for low impedance protec-
tion and ORANGE for thermal protection.
Load Impedance:
Measurement of speaker(s) resistance/reactance that the
amplifier must drive. The M Series protection circuitry
engages when a load impedance of less than 2
Ω
’s is present.
Mixed Mono:
The amplifier’s ability to play the Left and Right Stereo
channels while playing a third (bridged) mono channel.
Module Port:
18 pin connector located inside the M Series amplifiers designed
to connect Xtant’s accessory modules. Each M Series amplifier
has two Module Ports for every two channels of input.
PWM:
Pulse-Width Modulated power supply. Our regulated PWM
maintains a high conversion efficiency over an input supply
range of 10.5–15 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,
and CD players.
