Clip Light
– This indicator will flash if
clipping occurs in the EQ section of the
preamp. This can be remedied by
decreasing the amount of boost in the EQ
section or by decreasing the Gain control.
This light should never be on while playing.
Other EQ Considerations
yourself running out of amplifier headroom,
cut a little in the lower frequencies, which
require the most power from your amp.
Two areas are a frequent source of
frustration for bassists trying to achieve their
sound: frequency masking and frequency
enhancement. Frequency masking occurs
when other instruments (particularly cymbals
and electric guitars) obscure the important
upper harmonic content of your sound. As a
result, you find that the EQ settings that
were so perfect at home lack definition in a
live setting. On the other hand, the stage
settings that worked so well sound harsh
and/or thin in the absence of other
instruments. Frequency enhancement
results from cabinet placement and room
acoustics. A cabinet placed on the floor will
have the lower frequencies boosted by
about 3 db. Placement against a wall adds
another 3 db. A corner adds 3 db more.
Consequently you may find a surprising
boominess to your sound. Certain qualities
in the room itself can also enhance the lower
frequencies, further contributing to this
problem. Frequently this effect is more
noticeable in the audience than it is on
stage. Compensating for it may result in a
stage sound that may seem a little thin.
However the sound is actually quite full out
in front.
OTHER CONSIDERATIONS
Suggested Speaker Systems
speaker system, should be chosen to
accommodate the characteristics of your
amplifier and your predominant application.
If you will only be using one cabinet per
side, a 4 Ohm model will draw the most
current from your amplifier. If you will
generally be using two cabinets, they should
both be 8 Ohm models so their combined
impedance will be 4 ohms. If you are
uncertain about your future needs always go
with the 8 Ohm speaker option so that you
can add another speaker later if you need
to.
Headphone Jack as a Line Driver
some occasions (such as high-volume or
outdoor situations) it may be desirable to
use the Time Traveler along with an
– If you find
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
provided a signal that is post EQ and master
volume controls, allowing the entire system
to be controlled from the Time Traveler.
Using the Time Traveler With out
Speakers
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.
MAINTENANCE
Your Eden amplifier has been designed to
require minimal routine maintenance.
Attention to the following areas will ensure
optimum performance of your amplifier.
Contact Point Cleaning –
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,
– Your
cases, etc. 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.
