OPERATING CARE
EL AMP uses a high current
power supply and runs warm to the
touch. Avoid covering the top and rear
sides.
To ensure an optimal noise floor,
always position audio equipment as far
away as possible from wireless devices.
The Element can be safely powered on
24/7. For maximum relay lifespan, cycle
power at least once per month.
Do not lift amplifier by knob, or turn
knob beyond its limits.
Use gentle force when inserting or
removing cables.

Internal LED flashes, then turns off
Cause: Wrong power adapter detected
Solution: See Power Adapters section below
No sound in one channel
Cause: Bad cable, or incorrect computer settings
Solution: Check balance settings; try another headphone or RCA cable.
