Tuner Out Jack
– This standard ¼ inch jack is designed to provide a pre-
gain signal for connection to a tuner. It can also be used to provide pre-tone
signal to other devices such as a direct box or console. The signal is enough
to provide adequate signal to virtually every tuner on the market.
OPERATING INSTRUCTIONS
Mechanical and Thermal Issues
– During operation, your amplifier should
always be placed away from sources of moisture or heat. Care should be
taken not to obstruct the ventilation holes on the bottom and sides of the
unit. In the event of thermal shutdown, you should eliminate the cause of the
thermal problem (poor ventilation, speaker loads lower than 2 ohms)
immediately. The supplied rack ears can be used to install your amplifier in
a conventional equipment rack for protection during transportation.
Electrical Connection
– The NA320 requires at least 10 Amps of correctly
wired alternating current for proper operation. Providing less than 10 Amps
of power may result in poor amplifier performance, so it’s probably not a
good idea to plug all of your band’s gear into a single wall outlet.
Connections
– All instrument-level input connections (everything but the
speakers) should be made with high quality shielded cables. The use of
speaker cables for input connections will result in excess noise. Speaker
connections should be made with high quality 16 gauge or heavier
unshielded speaker cables. We recommend 10 or 12 gauge cables.
The use
of shielded line or instrument cables for speaker connections can
damage your amplifier
. The speaker cable should be as short as possible.
INITIAL SET UP
As bassists, each of us has in our head a concept of our perfect sound. Eden
amplifiers are designed to help you easily achieve the sound you hear inside
you. However, it’s a multi-step process as explained below.
In order to ensure the ultimate in tone, it’s important to follow the procedure
outlined below. Don’t skip steps; don’t jump around. Yes, this may take a
minute or two, but the work is well worth it. Once they’ve done it a few
times, most users can do it time and again in about a minute.
