Eden NA320 - Manual (Page 15)

Headphone Jack as a Line Driver – On some occasions (such as high-
volume or outdoor situations) it may be desirable to use the NA320 along
with an additional power amplifier and added cabinets. A standard shielded
instrument cable may be used to connect from the headphone jack of the unit
to an unbalanced input of a standard power amplifier. This will provide a
signal that is post-EQ and after the Master Volume control, allowing the
entire system to be controlled from the NA320. This way, you only have to
adjust one set of knobs. This is a Really Neat Thing, huh?
Using the NA320 Without Speakers -This amplifier is designed to be used
safely with headphones only, without the loud speaker plugged in. No harm
will result from using the amplifier in this fashion. This allows the use of the
unit for practice with headphones and as a preamplifier with other
amplifiers. Neighbors and room mates really love this, which qualifies it as
another Really Neat Thing.
MAINTENANCE
Your Nemesis amplifier has been designed to require minimal routine
maintenance. Attention to the following areas will ensure optimum
performance of your amplifier. We’re serious. Don’t blow this off, OK?
Contact Point Cleaning – One of the weakest links in most bass
amplification systems are the solderless connection points where
instruments, speaker cabinets, effects, and other devices are connected to the
amplifier. (The most vulnerable of these types of connection is the jack on
your instrument). In addition to contamination from airborne pollutants,
these points are frequently assaulted by connectors that have picked up
debris from dirty stages, cases, etc.
This contamination can result in poor contact as well as poor tone, and we
all know that bad tone is a Very Bad Thing. These points should be cleaned
regularly with a cotton swab soaked in denatured alcohol or a commercially
available de-oxidant. Frequent cleaning of the plugs on your cords is also
recommended.
Dust Removal – You should periodically inspect the ventilation openings
on the top and sides of the unit to ensure that they have not become blocked
by accumulated dust. Vacuum the openings to remove any dust buildup.
Dust bunnies are definitely not cool.
