LISTENING TIPS
OPERATING CARE
Listen safely to conserve your hearing:
www.hearingloss.org
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.
