Thank you for you purchase of the qtone DA-1001 20W Digital Amplifier. The unit has 4 inputs as
well as 2 outputs and up to 20 watts of amplification. As a digital amplifier it is very efficient (up to
93%!) While no audio is provided the amplifier uses very little power and while in use, due to its
efficiency, requires no heat-sink.
The outputs can be used to connect other devices to further use the selected inputs sound. The
“Audio Out” if from the selector before any tonal adjustment, meaning that it can be used to
connect to another amplifier or a recording device and without adjusting the input. The “VU Out” is
designed for the qtone AV-1001 Audio Visualiser, this output is after the tone controls so is
representative of the signal to the amplifier.
The Amplifier also provides power out from the unit (12V up to 3 amps). Two options are available,
one switched and one constant. The switched supply is turned on and off with the amplifier, useful
if ancillaries are needed to be turned off with the amp. Connecting to the constant permanent
supply will provide power regardless of the amplifiers state; as long as the amplifier is connected
to a power source.

* the outputs share power with the amplifier and each other. So there is a total of 1.5A or 3A (depending on speakers
impedance) between the switched and permanent outputs.
