Firmware Enters Unknown State
In the event a critical failure occurs and the firmware enters an
unknown condition, it will power down the amp and indicate
this condition with a specific blink code. Unplug the AC power
adapter for 30 seconds, then plug it back in to reset the MCU. If
this condition
persists, please contact Monoprice™ Technical
Support for assistance.
OPERATING GUIDELINES
To get the most out of your amplifier and to protect it from
possible damage, follow the guidelines listed below.
Gain Setting
While the amplifier supports hot switching the gain setting,
changing gain introduces a small DC transient at the output.
Depending on the sensitivity of your headphones, this transient
might be quite loud or damaging. We highly recommended that
you turn off the amplifier before changing the gain setting.
