Energy Star Sleep Mode
If no audio is present on any input of the power amplifier, the amplifier goes into a low power
“shutdown, or sleep mode” within 30 minutes. During sleep mode, power consumption of the
power supply and the amplifier is less than one (1) watt.
Two (2) audio inputs: Line In and Jack Line In
The
LINE IN
inputs accepts a balanced input via a Phoenix style screw terminal plug. The JACK
LINE IN accepts unbalanced input via 3.5 mini jack. The mini jack accept stereo inputs. The stereo
channels are summed together. This input is muted during Priority Override.
Priority Override Feature
The
Priority
input accepts balanced input levels of resistor selected 100 volts audio, 70 volts
audio, 25 volts audio and 1 volt (approximately line level) audio. Audio on the
Priority
input
suspends audio on the
Line In and Jack Line In
inputs and switches the speaker amplifier to pass
the
Priority
audio.
After the
Priority
audio stops, the unit waits before returning to the
Line In and
Jack Line In
audio input.
Balanced Line Level Output
A nominal 0dB level, balanced output is available at LINE OUT. The source of this output is both
balanced and Jack Line In sources.
Power Amplifier Features
The power amplifier outputs 2 times 20 watts or 40 watts total into 8 ohms and 15VDC power. The
class D power amplifier has reduced radiated electromagnetic interference (EMI) due to a special
feature of the power amplifier, operating in a patented spread spectrum. The power amplifier
protects itself from over-temperature, over-current, over-voltage conditions. The power amplifier
will shut itself down during these conditions.
IMPORTANT NOTE! This amplifier is intended for audio use only! Continuous sine wave drive
into a load will cause the amplifier to shut itself down when it heats up.
