Amplifier Operation

1. The LS has a short startup delay to protect the headphones. Do not

attempt to defeat this startup timing. Do not repeatedly push the

power button on and off because this will always reset the timing.

2. Plug the Monolith/Liquid Spark labeled power supply into the back

of the amplifier.

3. Press the power button to turn on the amplifier.

4. The small LED in the center of the front panel should light red.

5. After approximately 10 seconds the LED will turn white and the

headphones will be connected.

6. If the LED does not turn white within 30 seconds, please contact

Monoprice Tech Support Associates

7. Select gain with the center pushbutton. Pushbutton out is 3X, push

button in is 6X.

8. The preamp output is only active when headphones are not

plugged in.

9. To turn off the power push the power button again (pushbutton

out).

CAUTION: Please remember to turn down the volume (or power

down completely) before plugging or unplugging any sources or

headphones into or from your Liquid Spark.
